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.

★★ Do words in the URL really still have a true impact on Google rankings?
Google uses some signals from the words in the URL, but it's very, very weak. If Google can analyze the page content, it can essentially ignore the words in the URL. Having a word in a different langu...

★★ Can you really host your XML sitemap on an external domain?
The sitemap file can be hosted on a different domain and specified in robots.txt. This allows different departments within a company to manage sitemaps dynamically even if the main content takes time ...

★★ Do Google’s testing tools really give the same results?
All single URL testing tools (Single URL Inspection Tools or SUIT) use the same pipeline and infrastructure: Rich Results Test, Mobile-Friendly Test, AMP Test, and URL Inspection Tool. Differences in ...

★★★ Are URLs with # really invisible for Google SEO?
Fragment identifiers (URLs with #) are completely ignored for indexing. Google treats them as links to the same page. They do not affect rankings or featured snippets. Google may sometimes use them to...

★★★ Should you really use sitemaps to speed up the indexing of your content?
To help Google detect changes more quickly, changes need to be reported via a sitemap file. Most CMSs automatically generate sitemaps or feeds. The URL Inspection tool in Search Console can be used fo...

★★★ Should you really ignore the live test in Search Console to diagnose your indexing issues?
To verify how Googlebot really sees your page, examine the 'crawled page' version in the URL Inspection Tool instead of the 'live test'. The crawled version better reflects actual indexing because it ...

★★★ Why can't Google share JavaScript cache across your domains?

Martin Splitt Oct 15, 2020
★★★ Does domain age and the choice of CMS really influence Google rankings?
Website age is not a factor: Google does not favor either old or new sites systemically. The CMS used (WordPress, Wix, Blogger, etc.) does not matter: Google looks at the generated HTML pages. All mod...
John Mueller Oct 15, 2020
★★★ Do Links Without Anchor Text Really Hold Value for SEO?
There is definitely value in a link without anchor text (naked URL), but Google loses a bit of context. Links without anchors still allow for crawling and determining the importance of pages, but with...
John Mueller Oct 15, 2020
★★★ Why do Google test tools never reflect what Googlebot truly sees?
Testing tools (URL Inspection Tool, Rich Results Test, Mobile-Friendly Test, AMP Test) always perform a fresh fetch and bypass the cache to test the latest version. This differs from actual crawls and...

★★ Is Google’s rendering service blocking your cross-origin resources due to CORS?
Google's web rendering service is bound by CORS (Cross-Origin Resource Sharing) principles, APIs, and headers. If you have cross-origin requests to another subdomain or origin, you must ensure they ar...
