What does Google say about SEO? /
Domain age and historical factors remain hotly debated topics in the SEO community. This category compiles Google's official statements regarding how domain age, history, and accumulated reputation influence search rankings. SEO professionals frequently question whether the sandbox effect truly exists for new websites, whether older domains hold inherent advantages, and how a site's history impacts current performance—including previous ownership changes, past penalties, and archived content. Google representatives have consistently addressed these concerns, particularly regarding the concept of trust built over time. Understanding these official positions helps practitioners separate persistent myths from actual ranking factors recognized by Google's algorithms. This knowledge proves invaluable when acquiring expired domains, conducting site migrations, or implementing rebranding strategies where historical signals can significantly impact future SEO performance. These declarations provide clarity on what truly matters: quality content and user experience rather than mere domain age, helping SEO specialists make informed strategic decisions based on verified information rather than speculation or outdated assumptions about temporal ranking factors.

★★★ Does Nofollow still affect crawling without passing on PageRank?

★★★ 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...

★★★ Does rel=canonical really protect your syndicated content from ranking theft?
When syndicating an article with rel=canonical, two outcomes are possible: either Google indexes both pages separately (risking the syndicator ranking better), or Google chooses a unique canonical. Th...

★★★ 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...

★★★ Why does Google measure Core Web Vitals on the actual page version your visitors are really viewing?
For Core Web Vitals (a future ranking signal, announced at least 6 months in advance), Google will analyze the page that real users predominantly view (AMP or standard HTML depending on the user journ...

★★★ Is the rel=canonical really mandatory on all AMP pages, even standalone ones?
For paired AMPs (classic page + AMP), the canonical is required. For standalone AMPs (no classic version), the page must canonicalize to itself. This rule is independent of hreflang and translations....

★★★ Are URL parameters really a non-issue for SEO anymore?
URL parameters have not been an SEO problem for a long time. Google automatically handles the canonicalization of URLs with parameters. The parameter management tool is only useful for sites with tens...

★★★ 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...

★★ Can the JavaScript History API really force Google to change your canonical URL?
When JavaScript uses the History API to change the URL after the page has loaded, Google may interpret this change as a redirect and choose the modified URL as canonical. This behavior depends on the ...

★★ Do security alerts in Search Console really block Google's crawling?
Security alerts in Search Console (malware, phishing, hacked site) do not affect how Google crawls the site, but they can impact the display of pages in search results. Google remains cautious about w...

★★ 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...

★★ Should you really implement hreflang across an entire multilingual site?
Hreflang can be used selectively: only on certain pages (homepage, key pages) without needing to implement it site-wide. It’s a page-level annotation, not a global requirement....
John Mueller Aug 21, 2020
★★★ Can Google really block a site at position 11 to keep it off page 1?
Google has no algorithm or manual action that blocks a site at a specific position (e.g.: always position 11, never on page 1). If a site is considered relevant for position 11, it can also be relevan...

★★ 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...
John Mueller Aug 21, 2020
★★ Should you really let Google decide your crawl limit?
There is no recommended request/second limit (e.g., 30 req/s). The Search Console setting is a high limit, not a target. Google recommends leaving it on 'Google decides' unless crawling overloads the ...
John Mueller Aug 21, 2020
★★ Should you really keep nofollow on your footer links and service pages?
There is no need to use rel=nofollow on links to privacy policy pages or other service pages to prevent them from ranking. Google inherently understands that these site-wide linked pages are not the m...
John Mueller Aug 21, 2020
★★★ Is advertising on your site harming your SEO?
Displaying ads is not an SEO problem in itself. Google checks that the main content remains visible above-the-fold (not just ads) and that the site adheres to the Better Ads Standard (otherwise, Chrom...
John Mueller Aug 21, 2020
★★★ Is it true that AMP is a speed factor for Google?
AMP or non-AMP is not a speed criterion in itself: it is possible to create very fast pages without AMP and slow pages with AMP. Google measures the actual speed (future Core Web Vitals) of the versio...

★★ Do links in embedded tweets really affect your SEO?
When a tweet is embedded on a third-party site, Google can technically treat the links in that tweet as part of the page. However, Twitter heavily uses nofollow: these links generally have no direct S...
