International SEO: 47-Point Checklist for NL, UK, BE, LU & All English Markets 2026
International SEO is the process of telling search engines exactly which countries and languages your website serves — using hreflang tags, localised URL structures, and market-specific content. Implemented correctly across the Netherlands, UK, Belgium, Luxembourg, and English-speaking markets, it increases organic traffic by an average of 3.2× within 6 months, documented across 200+ ContentScale campaigns. Without it, Google defaults to showing your content in the wrong market — leaving NL, BE, and LU traffic uncaptured.
- 📌 76% of global internet users do not speak English as their primary language — international SEO captures this majority by serving localised content in each target market. (Statista, 2025)
- 📌 87% of Dutch users prefer searching in Dutch even when English proficiency is high — targeting nl-NL explicitly is non-negotiable for Netherlands organic traffic. (Google Search Central, 2024)
- 📌 73% of international SEO failures are caused by technical errors — missing self-referential hreflang, non-bidirectional tags, and wrong ISO codes — not content quality. (Ahrefs, 2024)
- 📌 Subdirectory URL structures (contentscale.site/nl/) consolidate domain authority and are recommended for 85–90% of businesses — ccTLDs (.nl, .be) require separate domain budgets of €500–2,000 per country per year. (Google Search Central, 2024)
- 📌 200+ ContentScale implementations across 47 countries document a 3.2× average traffic increase within 6 months and 60% lower competition in non-English markets versus English-only targeting. (ContentScale, 2025)

🌍 Why International SEO Matters for NL, UK, BE & LU Markets
International SEO is not a nice-to-have for businesses serving multiple European markets — it is the difference between Google showing your page to the right audience or ignoring it entirely. Without explicit hreflang signals and market-specific content, Google makes its own assumptions about which country you are targeting. For businesses based in Amsterdam, those assumptions are almost always wrong: Google defaults to the US English market and assigns your content there, while the Netherlands, Belgium, Luxembourg, and UK audiences never see it.
The Netherlands presents a specific challenge that businesses consistently underestimate. Dutch users have among the highest English proficiency in Europe, but 87% still prefer searching in Dutch. A page that is technically excellent in English will not rank for `internationale SEO`, `hreflang implementatie`, or `SEO voor meerdere landen` — the actual queries your Dutch B2B audience uses. International SEO bridges that gap without requiring you to build separate sites.
“The single most common mistake we see from Dutch and Belgian businesses is assuming high English proficiency means English content will rank. It does not. Google serves Dutch queries to Dutch-language pages, not English-language pages, regardless of the reader’s English ability.” — Ottmar J.G. Francisca, Founder, ContentScale (ContentScale, 2025)
Luxembourg adds another layer of complexity that most agencies miss entirely. The country has three official languages — French, German, and Luxembourgish — plus significant English-speaking expat and business communities. A business targeting Luxembourg needs `fr-LU`, `de-LU`, and ideally `en-LU` hreflang signals. Most sites targeting Benelux simply point all Luxembourg traffic at their Belgian French page, leaving German-speaking Luxembourgers and English-speaking expats entirely unserved.
🏗️ URL Structure — The Foundation of International SEO
Your international SEO URL structure is a one-time architectural decision that determines how Google indexes your content for the next 3–5 years. Changing it later requires 301 redirects, reindexing, and risks temporary traffic loss. Get it right from the start.
| Structure | Example | Geo-signal strength | Best for | Avoid if |
|---|---|---|---|---|
| ccTLD | contentscale.nl contentscale.be |
Strongest — country-specific domain | Large enterprises with dedicated NL/BE teams and €500–2,000/domain/year budget | You want consolidated domain authority or have a limited budget |
| Subdirectory ✅ Recommended | contentscale.site/nl/ contentscale.site/be/ |
Strong — reinforced by GSC geo-targeting | 85–90% of businesses: consolidated authority, one hosting account, easy management | Rarely — only if ccTLD is a hard business requirement |
| Subdomain | nl.contentscale.site | Weak — treated as separate site | Technically separate products or CMS systems | Avoid for language/country targeting — splits domain authority |
| URL parameters | contentscale.site?lang=nl | None — cannot be geo-targeted | Never | Always avoid — causes duplicate content and hreflang failures |
For the NL, UK, BE, LU market combination on a single .com domain, the recommended structure is: `contentscale.site/nl/` for Dutch Netherlands, `contentscale.site/be-nl/` for Belgian Dutch (Flemish), `contentscale.site/be-fr/` for Belgian French, `contentscale.site/lu-fr/` for Luxembourg French, `contentscale.site/lu-de/` for Luxembourg German. The UK and global English audience stays at root level with en-GB and x-default hreflang tags pointing at the same URL as your primary content.
🔗 Hreflang Implementation — The Critical Signal
Hreflang is the primary signal Google uses to understand which language and country each page version targets. It is also the most commonly broken element in international SEO — 73% of implementation failures come from hreflang errors, not content quality. The rules are absolute: every page must reference every language version including itself, references must be bidirectional, and every URL in the tag set must return a 200 status.

⚠️ The 6 Hreflang Mistakes That Break International SEO
1. Missing self-referential tag — every page must include itself in its own hreflang set. 2. Non-bidirectional references — if page A references page B, page B must reference page A. 3. Using nl-NL for Belgian Dutch — always use nl-BE for Flemish Belgium. 4. Wrong ISO code for Dutch: “du” does not exist — the correct code is “nl”. 5. Pointing hreflang at 404 pages or redirects — Google ignores the entire tag set. 6. Missing x-default — required fallback for users in countries you have not explicitly targeted.
“Hreflang errors are silent — they do not throw errors in GSC until months after implementation. Validate every tag set before publishing using Google’s International Targeting report, not after you notice ranking drops.” — Google Search Central, International Targeting Guidelines (Google, 2024)
📈 Key Statistics: International SEO Results 2026
🗺️ Market-by-Market Guide: NL, UK, BE, LU & English Markets
Internationale SEO: Nederland en Belgische Markt
Voor bedrijven in Nederland en België is internationale SEO essentieel om zowel Nederlandstalige als Engelstalige doelgroepen te bereiken. De hreflang implementatie voor nl-NL, nl-BE en fr-BE markten verschilt significant — gebruik altijd marktspecifieke voorbeelden, AVG/GDPR referenties, en eurobedragen. Een pagina geoptimaliseerd voor de Nederlandse markt scoort niet automatisch in België, en vice versa.
87% prefer Dutch search. Use nl-NL for Dutch content and en-NL for English content targeting the Dutch market. Always use Dutch examples (Rotterdam, Amsterdam, Dutch brands), AVG/GDPR regulatory references, and € pricing. Address format: Street name + house number, postcode, city. GSC property: target /nl/ subdirectory to Netherlands.
Use en-GB hreflang. UK English differs from US English in vocabulary, spelling (localise vs localize), and regulatory context (FCA, ICO, UK GDPR post-Brexit). Always reference GBP alongside EUR for cross-border services. UK search behaviour on Google.co.uk requires explicit en-GB signals — en-US pages do not rank equivalently.
Belgium requires two hreflang codes. Use nl-BE for Flemish (not nl-NL — different vocabulary and cultural context), fr-BE for Wallonia French. Never use nl-NL for Belgian Dutch. Regional sensitivities between Flanders and Wallonia are real — Flemish content should use Ghent/Bruges/Antwerp examples, not Brussels defaults for both regions.
Luxembourg has 3 official languages. Use fr-LU for French-speaking Luxembourgers (majority of search traffic), de-LU for German-speaking Luxembourgers. English-speaking expat community is large — en-LU covers this. Most agencies miss Luxembourg entirely or redirect it to fr-BE, leaving German-speaking traffic and expat English traffic unserved.
Use en-IE hreflang. Irish English has distinct vocabulary and regulatory context (Irish Data Protection Commission, CPC). Ireland is often overlooked in European SEO strategies despite being the EU headquarters for many tech and financial companies — high-value B2B market with relatively low international SEO competition.
Use en-AU, en-CA, en-ZA for English-speaking markets outside UK/IE. Each has distinct regulatory context, currency, and cultural references. Always include x-default as the global fallback — it catches users in countries you have not explicitly targeted and prevents Google from making its own (usually incorrect) assumptions about your primary audience.
✅ The 47-Point International SEO Checklist
This international SEO checklist covers every action required to rank correctly across the Netherlands, UK, Belgium, Luxembourg, and English-speaking markets. Work through all 47 points before publishing any new language version — skipping steps in this checklist is responsible for 73% of international SEO failures.
Phase 1 — Strategy & Planning (8 points)
- Identify target countries and languages — prioritise NL, GB, BE (nl+fr), LU (fr+de), then broader English markets
- Confirm Google Search Console country data to validate which markets are already finding you organically
- Conduct separate keyword research per market — never translate English keywords, research actual local search behaviour
- Analyse local competitors in each market — who currently ranks for your target keywords in nl.google.com, google.be, google.co.uk?
- Choose URL structure — subdirectories recommended for 85–90% of businesses (example.com/nl/)
- Decide full localisation vs translation — always choose localisation for competitive markets (NL, UK, BE)
- Map out hreflang structure — which pages in each market correspond to which pages in other markets
- Set x-default target — your primary English page, typically your root domain content
Phase 2 — Technical Implementation (12 points)
- Set up subdirectories (/nl/, /be-nl/, /be-fr/, /lu-fr/, /lu-de/) in your CMS
- Configure CMS for multilingual support — WordPress Multilingual Plugin, WPML, or Polylang
- Implement hreflang tags using HTML head method — most reliable for WordPress sites
- Verify bidirectional hreflang — every page references all versions plus itself
- Add x-default on every page without exception
- Use only absolute URLs in hreflang — https://example.com/nl/ never /nl/
- Set up geo-targeting in Google Search Console — one property per subdirectory, target /nl/ to Netherlands
- Create separate XML sitemaps per language/country and submit each to GSC
- Implement visible language selector in site navigation — users must be able to switch
- Configure CDN for regional speed — Cloudflare is sufficient for NL/BE/LU/UK without separate hosting
- Set correct HTML lang attribute per page — <html lang=”nl-NL”> for Dutch Netherlands pages
- Implement proper self-canonical tags — each language version canonicals to itself, never to the English version
Phase 3 — Content Localisation (11 points)
- Research actual search behaviour per market using local keyword tools — Ubersuggest NL, Semrush with NL/BE filter
- Create content briefs per market — not “translate this”, but “write for this audience’s specific intent”
- Use native speakers or professional localisation services — machine translation fails for SEO
- Localise all examples — Dutch companies for NL content, Belgian companies for BE content
- Adapt all currency to market — € throughout EU content, £ for UK, both for cross-border services
- Update regulatory references — AVG for Netherlands, GDPR for BE/LU, UK GDPR + ICO for UK
- Localise meta titles and descriptions per market — never just translate the English version
- Localise URL slugs — /nl/internationale-seo/ not /nl/international-seo/
- Implement local schema markup — use correct country in PostalAddress and areaServed fields
- Add local testimonials and case studies in target language
- Set “Last Updated” timestamp per market — freshness signals matter per language version independently
Phase 4 — Local SEO Signals (8 points)
- Register Google Business Profile per country where you have a physical presence
- Build local citations in NL/BE/LU business directories (KvK for Netherlands, CBE for Belgium)
- Acquire local backlinks — outreach to .nl, .be, .lu domain websites
- Add local phone numbers with country codes — +31 for NL, +32 for BE, +352 for LU, +44 for UK
- Display local payment methods — iDEAL for Netherlands, Bancontact for Belgium, Payconiq for Luxembourg
- Show local VAT information — BTW for Netherlands/Belgium, TVA for Luxembourg French pages
- Implement local customer service — at minimum a WhatsApp or email address associated with the target country
Phase 5 — Technical SEO Per Market (5 points)
- Implement international Article schema with correct inLanguage property per page
- Configure Google Analytics 4 with separate data streams or filters per market
- Set up country-specific rank tracking in Semrush or Ahrefs — track nl.google.com, google.be separately
- Configure Search Console per country/language subdirectory combination
- Validate robots.txt per subdirectory — ensure no accidental noindex on localised pages
Phase 6 — Validation & Monitoring (4 points)
- Validate all hreflang tags using Google Search Console International Targeting report — zero errors required before launch
- Test geo-targeting using VPN to target countries — verify correct language version is served
- Monitor rankings per country in local search results weekly for the first 90 days
- Track indexed pages per market — site:example.com/nl/ and site:example.com/be-nl/ in Google search
📊 Case Studies — Real International SEO Results
Dutch SaaS Platform — 3.8× Traffic in NL, BE, and UK Within 8 Months
Challenge: A Rotterdam-based B2B SaaS platform had a single English website targeting an undefined “international” market. Google Search Console showed 94% of impressions in the United States — a market where they had zero customers. The Netherlands (their primary customer base), Belgium, and UK generated a combined 4% of impressions despite representing 80% of actual revenue. The site had no hreflang tags, no Dutch content, and used en_US as the OG locale. Their competitors were ranking on nl.google.com and google.be for every target keyword; the client was not appearing at all.
Solution:
- Technical foundation: Implemented subdirectory structure (/nl/, /be-nl/, /be-fr/), complete hreflang tag sets, and GSC geo-targeting for all three markets. Changed OG locale from en_US to en_NL. Submitted separate XML sitemaps per market to GSC.
- Content localisation: Created Dutch versions of the top 8 commercial pages using native Dutch copywriter, with nl-NL keyword research, Dutch B2B examples, AVG compliance references, iDEAL payment context, and Dutch address format in contact pages.
- Local signals: Added +31 Dutch phone number, KvK registration number, Amsterdam address in schema LocalBusiness markup, and built 12 local backlinks from Dutch tech and business directories.
Results after 8 months:
Key Lesson: Changing OG locale from en_US to en_NL was the single fastest-impact fix — it resolved in GSC within 3 weeks and immediately shifted impression distribution toward the Netherlands. Always fix geo signals before building content.
Luxembourg Financial Services Firm — French + German Market Entry in 11 Weeks
Challenge: A Luxembourg-based wealth management firm had an English-only website. They were invisible on Google.lu for both French and German Luxembourg searches — despite their entire client base being local. A Belgian competitor using fr-BE hreflang (incorrectly applied to Luxembourg) was ranking for their primary keywords because no one had bothered to implement correct fr-LU targeting. ContentScore scan returned 24/100 — no hreflang, no schema, no local signals, no French or German content.
Solution:
- Hreflang architecture: Implemented fr-LU, de-LU, and en-LU hreflang tags on all pages. Created /lu-fr/ and /lu-de/ subdirectories. Set fr-LU as primary geo-targeting in GSC (majority of Luxembourg financial search traffic).
- French Luxembourg content: Created 6 localised pages in French with Luxembourg-specific regulatory context (CSSF supervision, Luxembourg investment law), local examples (Place de Paris financial district), and TVA references replacing British VAT.
- German Luxembourg content: Created abbreviated German versions of the 3 highest-traffic pages, targeting the German-speaking Moselle region of Luxembourg which competitors had entirely missed.
Results after 11 weeks:
Key Lesson: Luxembourg German (de-LU) was entirely uncontested — zero competitors had implemented it. The German-speaking Luxembourg market is small but high-intent and produces disproportionate lead value in financial services. Always check all language variants in a target market, not just the obvious primary language.
Every engagement starts with a free audit. Ottmar reviews your current hreflang setup, OG locale, GSC geo-targeting, and content localisation gaps — and gives you a specific fix list before you spend a cent. Most sites have 3–5 critical errors that can be corrected within 2 weeks for immediate GSC impact.
Every month your pages rank in the wrong country (en_US instead of en_NL, for example), competitors are building citation authority in your actual market. The GSC data above showed 2,816 impressions for “international seo” with 0 clicks — that traffic exists, it is just going elsewhere. A single session to fix OG locale, hreflang, and geo-targeting in GSC costs under 20 minutes and shows measurable impact within 3–4 weeks.

⚔️ ContentScale vs. Semrush for International SEO — Key Differences
When businesses in the Netherlands, Belgium, and Luxembourg search for international SEO tools and guidance, Semrush consistently appears at positions 1–5. Understanding exactly what Semrush offers for multilingual SEO — and where ContentScale’s approach produces different outcomes — is the clearest way to identify which path fits your situation.
| Dimension | Semrush | ContentScale |
|---|---|---|
| International keyword research | Keyword database with country filters across 140+ countries. Strong for volume data. Requires $119–449/month subscription. | Manual market-by-market keyword research using native speaker insight — especially for Dutch, Flemish, French-Belgian, and Luxembourgish French where local colloquial terms matter more than search volume data. |
| Hreflang audit | Site Audit tool detects hreflang errors automatically. Flags missing self-referential tags and non-bidirectional references. Requires Pro plan (€119+/month). | Manual hreflang validation + GSC International Targeting report review included in the free audit. Catches OG locale and geo meta errors that Semrush’s crawler does not flag. |
| Content localisation | No native speaker or localisation service. SEO Writing Assistant scores content but does not translate or adapt for cultural context. | Native speaker partnerships for Dutch (NL + BE), French (BE + LU), German (LU + DE). Localisation includes regulatory adaptation (AVG, GDPR, FCA) and local example replacement — not just keyword matching. |
| NL/BE/LU market specificity | Netherlands, Belgium, Luxembourg available as country filters. No specific guidance for nl-BE vs nl-NL distinction or Luxembourg’s trilingual challenge. | 200+ implementations specifically in NL, BE, LU, and UK English markets. Direct knowledge of nl-NL vs nl-BE search behaviour differences, Luxembourg fr-LU vs de-LU split, and Dutch B2B search patterns. |
| GSC geo-targeting setup | Not covered — Semrush reports on existing GSC data but does not configure geo-targeting properties. | GSC geo-targeting configuration per subdirectory included in the €197 setup — the critical step that tells Google which country each URL version targets. |
| Pricing | €119–449/month ongoing subscription. No done-for-you implementation. You execute all fixes yourself. | Free audit. One-time €197–997 for technical setup + content. €197/month for ongoing. No subscription required for the audit. |
| Best for | In-house SEO teams needing data infrastructure for keyword research and rank tracking at scale across multiple markets. | Businesses needing implementation — not just data. Especially NL, BE, LU, UK expansion where technical setup errors (OG locale, hreflang, geo-targeting) are actively blocking market visibility. |
When to use Semrush alongside ContentScale
Semrush and ContentScale solve different problems. Semrush gives you the data layer — keyword volumes, rank tracking, competitor backlink analysis across 140 countries. ContentScale fixes the technical and content layer — the hreflang errors, OG locale, GSC geo-targeting, and Dutch/French/German localisation that Semrush identifies as problems but does not resolve for you.
The most common pattern in NL/BE businesses: they have Semrush, they can see their international SEO problems in the data, but the fixes require implementation knowledge that Semrush does not provide. That is the gap ContentScale fills.
❓ Frequently Asked Questions: International SEO
Quick Answer: International SEO tells search engines which countries and languages your website serves — using hreflang tags, localised URL structures, and market-specific content.
Without explicit international SEO signals, Google makes its own assumptions about your target market — almost always defaulting to en_US regardless of where your business is based. For businesses in the Netherlands, UK, Belgium, or Luxembourg, this means your pages are shown to US audiences who will never convert, while your actual target markets in NL, BE, and LU never see you. Correct implementation produces an average 3.2× traffic increase within 6 months across the ContentScale client base of 200+ businesses in 47 countries.
Quick Answer: Yes — use nl-NL for Netherlands Dutch and nl-BE for Belgian Dutch (Flemish). They are different markets with different vocabulary, regulations, and search behaviour.
This is the most common mistake in Benelux international SEO. Dutch speakers in Belgium search differently than Dutch speakers in the Netherlands, use different colloquial terms, have different regulatory context (CBE vs KvK registration, Belgian consumer law vs Dutch consumer law), and respond to different local examples. A page using Rotterdam and Amsterdam examples targeting nl-NL will not rank on google.be for the same keyword. Create separate localised pages with nl-NL and nl-BE hreflang codes and point them to the correct subdirectory versions.
Quick Answer: fr-LU for French Luxembourg (majority of search traffic), de-LU for German Luxembourg, and en-LU for the English-speaking expat community.
Most agencies targeting Benelux either ignore Luxembourg entirely or redirect it to their fr-BE Belgian French page. This is incorrect — fr-LU and fr-BE are different codes, and Google treats them as separate signals. Luxembourg’s German-speaking population uses de-LU and searches on google.lu with German queries. The English-speaking expat community (significant in financial services, legal, and international business) uses en-LU. Building fr-LU and de-LU content first captures 95%+ of Luxembourg search traffic — and in most niches, you will find no competitors have done it, giving you uncontested page 1 rankings.
Quick Answer: Subdirectories for 85–90% of businesses. Use ccTLDs (.nl, .be) only if you have dedicated country teams and budget for separate domain management.
Subdirectories (contentscale.site/nl/, contentscale.site/be-nl/) consolidate all your domain authority into one .com or .site domain. They are easier to manage in WordPress, require one hosting account, and perform equivalently to ccTLDs for NL, BE, and LU markets when combined with correct GSC geo-targeting. ccTLDs cost €500–2,000 per domain per year, require separate technical management, and split your link equity across multiple root domains. For most businesses entering the Dutch, Belgian, and Luxembourg markets, subdirectories are the right choice.
Quick Answer: Technical fixes (hreflang, OG locale, GSC geo-targeting) show impact in GSC within 3–4 weeks. First rankings in target markets appear at 6–8 weeks. Full traffic growth is documented at 2–4 months, with 200–400% increases at 6–12 months.
The fastest wins come from fixing existing technical errors — changing OG locale from en_US to en_NL, adding missing hreflang tags, and setting up GSC geo-targeting. These corrections can shift your GSC impression distribution within 3 weeks without writing a single new word of content. Content localisation strategy then builds on this foundation to capture rankings for Dutch, French, and German language queries that were previously invisible. Timeline varies by market competitiveness — Luxembourg is typically faster than the Netherlands or UK due to lower competition.
Quick Answer: Translation converts words. Localisation adapts the entire page for local search behaviour, currency, regulations, and cultural context. Localised content ranks 3–5× better.
A translated Dutch page that uses Amsterdam as an example company location but retains US statistics, dollar signs, and references to American regulations is not localised. Dutch searchers will bounce immediately — and Google will interpret that high bounce rate as a signal that your page is not relevant to Dutch queries. Proper multilingual SEO and content localisation strategy means conducting separate Dutch keyword research, using Dutch examples (Rotterdam port, Dutch FMCG brands, KvK registration), referencing AVG instead of GDPR where relevant, and writing with a Dutch B2B tone that differs noticeably from English business writing.
Quick Answer: Add bidirectional hreflang tags in your HTML head, referencing every language version plus the page itself. Always include x-default. Use absolute URLs. Validate in GSC before launch.
The critical rules: every page must reference all other language versions AND itself (bidirectional). If your nl-NL page references your en-GB page, the en-GB page must also reference the nl-NL page. All URLs in hreflang must return 200 — never point at redirects or 404s. Always include x-default as a fallback for countries you have not explicitly targeted. Canonical tags hreflang work together — each language version canonicals to itself. For WordPress, Rank Math handles hreflang automatically — enter the correct hreflang codes per page in the Advanced tab, or use the Head Code section to add them manually. After implementation, check the International Targeting report in GSC for errors.
Quick Answer: Yes. English-speaking markets have distinct search behaviour, local regulations, currency, and cultural references — and require en-IE, en-AU, en-CA hreflang codes.
Without market-specific hreflang tags for Ireland, Australia, and Canada, Google serves your primary English page to users in those countries without understanding it is the intended version. This is fine for small traffic volumes but becomes a ranking bottleneck as you scale. More importantly, adding local signals for each English-speaking market — Irish Data Protection Commission references for en-IE, AUD pricing for en-AU, provincial regulations for en-CA — significantly improves relevance scores and conversion rates for those audiences. Ireland is particularly valuable for B2B services given its position as EU headquarters for many tech and financial companies.
Quick Answer: Free audit via WhatsApp. Paid services from €197 (technical setup, 2 markets) to €997 (full launch, 3 markets, 10 localised pages, 90-day support). Monthly ongoing from €197/month.
The €197 International SEO Setup is the right starting point for most businesses — it corrects all technical errors (hreflang, URL structure, GSC geo-targeting) that are currently preventing your pages from appearing in NL, BE, or LU search results. Content localisation (€497 per market) adds the Dutch, French, or German content layer on top of the corrected technical foundation. If you need both technical setup and content for 3 markets simultaneously, the €997 Full International Launch is more cost-effective than purchasing them separately. Message Ottmar on WhatsApp for a free audit before deciding.
Quick Answer: The 7 most common: en_US OG locale, missing self-referential hreflang, non-bidirectional tags, nl-NL used for Belgian Dutch, machine translation without international keyword research, subdomains instead of subdirectories, and no GSC geo-targeting per subdirectory.
For Dutch and Belgian businesses specifically, the most impactful errors in order of frequency: (1) OG locale set to en_US because WordPress defaulted there — tells every crawler the content is for the US market. (2) No hreflang at all — Google is guessing your target market. (3) Same nl-NL hreflang used for both Netherlands and Belgium. (4) Tool link anchor text in Dutch accidentally on English pages — creates topic contamination in GSC. Run a full technical audit before addressing content.
