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.

★★ Are URL parameters still an obstacle for organic search?
URLs with parameters (query strings) have been perfectly acceptable to Google for a long time. The URL parameter management tool is only useful for very large sites (millions of pages) generating an e...

★★★ Is Google really merging your multilingual pages into a single canonical URL?
When a site has identical content pages targeting different countries (e.g., French Canada vs. France), Google may group (fold) them into a single canonical version in the index. In Search Console, on...

★★★ Do cascading internal 301 redirects really drain SEO juice?
Even if internal navigation points to old URLs that redirect via 301, Google follows the chain and treats the link as going directly to the final destination (the canonical). No loss of value. Users c...

★★ Is it really necessary to manually de-index your old pagination URLs?
When pagination is removed, old paginated URLs either return the homepage (automatically canonicalized) or a 404 (de-indexed upon recrawl). Google manages this naturally over time without any manual d...

★★★ Is it really necessary to index all pagination pages to optimize your SEO?
Google must index paginated pages to recover all content and internal links (e.g., products from an e-commerce category). Each paginated page needs to be linked with standard HTML links (next/previous...

★★★ Do internal 301 redirects really dilute PageRank?
If your internal links point to URLs that redirect via 301, Google follows the redirect, identifies the final URL as canonical, and treats the link as if it points directly to the destination. No loss...

★★ Should you manually deindex old pagination URLs after changing your site's architecture?
If you disable pagination on a blog, there's no need to manually deindex old paginated URLs. Google will re-crawl them, see that they return the homepage (200) or a 404, and will naturally process the...

★★★ Does Nofollow still affect crawling without passing on PageRank?
Google can now follow nofollow links to discover new URLs and potentially index them. However, the transmission of PageRank and ranking signals through these links remains independent of the crawl dec...
John Mueller Aug 21, 2020
★★★ Should you still tag your affiliate links with rel=sponsored?
For common affiliate configurations (Amazon, Booking, eBay), Google already recognizes these URLs and treats them as nofollow links internally. Therefore, there is no risk of penalty if you have not a...

★★★ Why does Google ignore the lastmod dates in your XML sitemap?
If all the URLs in a sitemap have the same modification date (e.g., today's date), Google ignores this information and uses the sitemap only to discover new URLs. The priority and changefreq fields ar...
John Mueller Aug 21, 2020
★★★ How does Google really discover your new URLs?
Google doesn't guess URLs: it discovers them through links (internal, sitemaps, RSS, tweets, public emails, etc.). There is no back-door access to the server. A URL mentioned nowhere will never be cra...
John Mueller Aug 21, 2020
★★★ Does nofollow really block indexing, or can Google still crawl those URLs?
Google can now follow nofollow links to discover new URLs and potentially index them. However, the passing of PageRank and ranking signals through nofollow remains independent and is not guaranteed: j...
John Mueller Aug 21, 2020
★★★ Why does Google ignore identical modification dates in your sitemaps?
If all URLs in a sitemap have the same modification date (for example, today's date), Google completely ignores this lastmod field and uses the sitemap only to discover new URLs, not to prioritize re-...
John Mueller Aug 21, 2020
★★ Are sitemaps really essential for Google indexing?
Google discovers new URLs through various means: internal links, RSS feeds, tweets, public mailing lists, external links. The sitemap is not the only source. Google does not guess URLs; it must find t...
John Mueller Aug 21, 2020
★★★ Is it really necessary to optimize the first link on a page for SEO?
Contrary to the common belief that only the first link matters, Google can take multiple links pointing to the same URL on a page into account and combine their anchor signals. There is no need to man...
John Mueller Aug 21, 2020
★★★ Should you still fill in the priority and changefreq attributes in your XML sitemaps?
Google does not use the priority or changefreq attributes in sitemap files. Only the URL and the lastmod date are taken into account. Priority has been ignored because websites filled it out in a non-...
John Mueller Aug 21, 2020
★★★ Is cross-domain duplicate content really harmless for your SEO?
Having the same content in the same language across multiple domains (e.g., English content on .com and .pl) is not penalized. Google simply chooses a canonical URL. If the content differs slightly (l...

★★ Does changing your navigation really impact your rankings?
For a modified navigation structure, Google handles the change very smoothly if only the internal navigation changes without modifying the URLs. It's not akin to a complete restructuring requiring a t...
