What does Google say about SEO? /
Domain names represent a foundational element of any SEO strategy, and Google's official statements on this topic provide essential clarifications for search engine optimization professionals. This category compiles all of Google's positions regarding the impact of domain choices on rankings: the influence of extensions (generic vs geographic TLDs), the use of subdomains versus subdirectories, the relevance of exact match domains (EMD), and technical questions related to URL structures. Google has regularly clarified its stance on these aspects, particularly concerning the relative importance of domain names in the ranking algorithm. Understanding these declarations helps dispel persistent misconceptions, such as overvaluing keywords in domains or myths surrounding certain extensions. Official recommendations also cover domain migrations, the use of the www prefix, trailing slash management, and optimal URL architecture. For SEO experts, this information proves crucial when launching new projects, undertaking redesigns, or developing international strategies, enabling informed decisions based on verified facts rather than assumptions. These insights directly impact technical SEO implementation and help align domain strategy with Google's actual ranking factors and best practices for sustainable organic visibility.

★★★ How does Google group your pages to measure Core Web Vitals?

★★★ Does Google really track Core Web Vitals for AMP and non-AMP pages separately?
Google tracks CWV data for both AMP and non-AMP versions separately based on actual user data. If users go directly to the non-AMP URLs and use Search to access the AMP URLs, both versions will have d...

★★★ How does Google really group your pages to evaluate Core Web Vitals?

★★★ Do 301 redirects really transfer all ranking signals without any loss?
With a 301 redirect, Google groups the old and new URLs together and transfers all signals (links, etc.) to the canonical URL (usually the destination). It's also necessary to update internal and exte...

★★★ Should you create related content to boost your topical authority?
Creating content on topics related to your main field (e.g., laptop reviews if you sell laptops) helps build a reputation for knowledge in this area for both Google and users. This strengthens trust a...

★★★ Do 301 redirects really pass on 100% of PageRank and link signals?
With a 301 redirect, Google groups the old and new URL together and transfers all signals (including links) to the canonical URL, usually the destination of the redirect. To ensure that the new URL is...

★★★ Can a low-quality page really taint your entire site?
Google tries to evaluate each URL individually and in detail. However, the pages on a site link to each other. If a main page is of low quality, it affects the others because they revolve around it. A...

★★ Why does Google keep crawling outdated 404 URLs on your site?
It is normal for Google to check old URLs that return 404 from time to time, even after years. This is not a sign of a problem, just the systems ensuring nothing is missed. Old sites naturally accumul...

★★★ Core Web Vitals: Which version truly impacts your ranking when Google shows the AMP?
When Google has data for both AMP and non-AMP versions and displays the AMP version in the results, it is the data from the AMP version that is used for ranking. This principle also applies to interna...

★★ Why does Google keep rechecking your old 404 URLs for years?
Google keeps old 404 URLs in its systems and periodically rechecks them (sometimes once a year) to ensure they still return 404. This is not a problem. On older sites, the number of 404 URLs naturally...

★★ Could Google hide one of your sites if they look too similar?
For two distinct sites without duplicate content, Google should rank them individually. If multiple very similar domains exist, Google may show only one. With two unique sites, they should appear sepa...
John Mueller Feb 05, 2021
★★ Is it true that Google never disconnects your old pages during a migration?
During a migration, Google does not de-index the old page before re-indexing the new one. The process works via canonical change: Google sees the redirect, checks that the content is identical, and sw...
John Mueller Jan 29, 2021
★★★ Does a website that changes ownership inherit Google penalties?
When a site changes ownership and domain, Google does not apply previous manual actions to the new owner. If no manual action appears in Search Console, the site is treated as normal. Algorithms evalu...
John Mueller Jan 29, 2021
★★★ Does Google really transfer all signals in bulk during a complete site migration?
During a complete site migration, if Google can recognize that all indexable content has been moved, it transfers all signals in bulk to the new domain. This is more efficient than a partial migration...
John Mueller Jan 29, 2021
★★★ Subdomains vs Subdirectories: Is there really an SEO advantage to favoring one over the other?
Google's systems are designed to treat subdomains and subdirectories essentially equivalently. There is no automatic bonus for choosing one over the other. The choice should be based on considerations...

★★ Should you really submit both mobile AND desktop versions in your sitemap?
If the mobile/desktop annotations are correctly implemented in the pages themselves, it is unnecessary to include both versions (mobile and desktop) in the sitemap. Submitting either of the two URLs i...

★★ Is it really sufficient to include only one version, mobile or desktop, in your XML sitemap?
For a site with separate mobile and desktop URLs, it is enough to include only one version in the sitemap if the bidirectional annotations are present in the HTML code. There is no need to include bot...
Google Jan 28, 2021
★★ Does the http:// or https:// namespace in an XML sitemap really affect crawlability?
In the XML Sitemap, using http:// or https:// for the namespace URL (xmlns) has no functional importance. Google treats both identically. Conventionally, http:// is more common....

★★★ Should you really use the manual indexing request in Search Console?
The indexing request feature in the URL inspection tool is back in Search Console. It allows individual pages to be manually submitted for indexing in specific situations where it is useful....
