Gary Illyes sets a clear criterion: any solution claiming to replace hreflang must work for all types of sites — parameterized URLs, country-specific domains, various template systems. The problem? No current proposal fulfills this promise of universality without forcing the Internet to change its architecture. For SEOs, this means we remain stuck with hreflang, despite its complexity.
What you need to understand
What problem is hreflang supposed to solve? <\/h3>
Hreflang tells Google which language or regional version <\/strong> of a page to display to a given user. Without this signal, the engine guesses — often wrongly — and shows the English version to a French person or the Spanish version from Spain to a Mexican.<\/p> The hreflang annotation works via three methods: HTML tags in the head <\/strong>, attributes in the XML sitemap, or HTTP headers. Each page must reference all its variants, including itself. It's cumbersome, redundant, and the slightest error breaks the system.<\/p> Hreflang is a implementation nightmare <\/strong> at scale. Adding a new language to a site of 50,000 pages means modifying 50,000 tags. Mistakes are common: incorrect language codes, incomplete circular references, conflicts between sitemaps and HTML tags.<\/p> Third-party solutions are regularly emerging: automatic detection via IP geolocation <\/strong>, JavaScript redirects based on browser language, simplified custom meta tags. The fantasy? A system that "guesses" everything on its own without heavy maintenance.<\/p> Illyes sets a non-negotiable universality criterion <\/strong>: the solution must work everywhere. Sites with URL parameters changing the language (?lang=fr), completely separate domains (.fr vs .mx), subdomains (fr.site.com), subdirectories (\/fr\/), varied template systems (WordPress, Shopify, custom).<\/p> And this is where it gets tricky. A solution based on IP geolocation? Useless for distinguishing Spanish from Spain vs. Spanish from Mexico <\/strong> — even potentially the same IP. Detection via browser language? Too volatile, a French person may navigate in English. Automatic redirection? Incompatible with parameterized URLs where the very structure changes.<\/p>Why are we looking for alternatives? <\/h3>
What does Gary Illyes really say about these attempts? <\/h3>
SEO Expert opinion
Is this statement consistent with what we observe on the ground? <\/h3>
Absolutely. I've seen dozens of projects attempt homemade systems to bypass hreflang <\/strong>. The result? It works in 70% of cases, then collapses on edge cases. An e-commerce site launching a Canadian French version discovers that its IP detection classifies Quebec and France together. A media outlet using URL parameters realizes that its variants are not indexed.<\/p> The real problem raised by Illyes — without explicitly saying so — is that any simplification hides a loss of control <\/strong>. Hreflang is verbose precisely because it allows the webmaster to declare each relationship explicitly. Automatic alternatives presume rules that never fit perfectly.<\/p> Illyes doesn't say that hreflang is perfect. He says that the proposed alternatives are worse <\/strong>. That's different. The real critique we can make: Google could improve hreflang itself rather than dismiss any alternative.<\/p> For instance, why not allow a centralized declaration in a JSON file <\/strong> instead of redundant annotations on each page? Why not propose an intelligent fallback system when a hreflang relationship is incomplete rather than ignoring the entire chain? [To verify] <\/strong> but Google could technically validate and correct some minor hreflang errors instead of breaking everything.<\/p> Let’s be honest: for a site of less than 100 pages with 2-3 languages <\/strong>, hreflang remains simple. Illyes’s universality criterion mainly aims at solutions claiming to replace hreflang at scale. A small corporate site can get by with HTML tags in the head — it’s manageable.<\/p> The real challenge concerns complex international sites <\/strong>: marketplaces with thousands of local sellers, media with ultra-segmented regional versions, SaaS platforms with dynamically translated content. Here, no alternative holds up to the diversity of structures. And this is precisely the audience targeted by this statement.<\/p>What nuances should be added to this position? <\/h3>
In which cases does this rule not apply? <\/h3>
Practical impact and recommendations
What should be done concretely if managing a multilingual site? <\/h3>
Accept that hreflang remains the standard and implement it correctly rather than looking for shortcuts <\/strong>. This means choosing a method (HTML, sitemap, or HTTP headers) and sticking to it. For large sites, XML sitemaps are often the most maintainable: centralization, no template modification, simplified auditing.<\/p> Document each language relationship in a mapping table <\/strong> before even coding. If you have \/fr\/chaussures, \/en\/shoes, \/es\/zapatos, list all the equivalents. This preparatory work avoids 80% of mistakes. And use validation tools: Google Search Console points out hreflang conflicts, as do third-party validators like Merkle or Screaming Frog.<\/p> Never mix implementation methods. If you have HTML tags and <\/strong> sitemap annotations that contradict each other, Google ignores everything. Choose a single approach. Another classic mistake: forgetting the reference to itself <\/strong>. The page \/fr\/produit must include a hreflang to itself, not just to its variants.<\/p> Also avoid incomplete chains. If \/fr\/ points to \/en\/ but \/en\/ does not point to \/fr\/, the relationship is broken <\/strong>. Hreflang works on the principle of reciprocity — each page must reference all the others, and vice versa. Finally, do not confuse language codes (fr, en) and language-region codes (fr-FR, fr-CA): if you target Quebec AND France, use the regional variants.<\/p> Audit in three steps. First, crawl the site with Screaming Frog <\/strong> in hreflang mode and export the error report. Check for missing codes, incorrect circular references, or orphan pages (no other page references them). Next, cross-check with Google Search Console: "International targeting" section to see conflicts detected by Google.<\/p> Third verification: real user testing. VPN on different geographical IPs <\/strong> and browser configured in different languages. Check that Google displays the correct version according to the profile. If a Spaniard consistently sees the English version, it means hreflang is not working — or Google is ignoring it due to errors.<\/p>What mistakes should absolutely be avoided? <\/h3>
How can I check that my implementation is compliant? <\/h3>
