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age, helping SEO specialists make informed strategic decisions based on verified information rather than speculation or outdated assumptions about temporal ranking factors.

★★★ How Does Google Actually Determine the Canonical URL of Your Pages?
John Mueller provided on Twitter a list of criteria that Google takes into account to define what the canonical URL of a page is (and therefore its "canonicalization"): redirects, internal links, exte...

★★ 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...

★★ 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...

★★ 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 ...

★★★ 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...

★★★ 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...

★★★ 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...

★★ Is it really necessary to nofollow site-wide links to your legal pages to optimize PageRank?
Having 10 links instead of just one to a legal page (privacy, contact) on every page of the site probably wouldn't change anything. Google understands that these pages are linked everywhere without be...
John Mueller Aug 21, 2020
★★ Should you really set a crawl limit in Search Console?
The crawl limit setting in Search Console defines a maximum that Google will not exceed, not a volume that Google will always achieve. Google recommends keeping this setting on 'automatic' unless craw...
John Mueller Aug 21, 2020
★★★ Is rel=canonical in syndication really reliable for controlling indexing?
If you publish your content on other sites with a canonical link pointing to your page, Google can either index both pages separately (if they are sufficiently different) or choose a canonical URL by ...
John Mueller Aug 21, 2020
★★★ Do Core Web Vitals really measure what your users actually see?
For Core Web Vitals (a future ranking factor), Google measures the performance of the version of the page that users actually see: the AMP version if that’s what displays, the classic HTML version oth...
John Mueller Aug 21, 2020
★★★ Why does Google require a canonical on ALL AMP pages, including standalone ones?
All AMP pages must have a rel=canonical, whether they are connected to a traditional HTML version or are standalone AMP pages. In the case of standalone AMP, the canonical points to the page itself....
John Mueller Aug 21, 2020
★★★ Can you truly prioritize certain pages in Google without a dedicated meta tag?
Google does not allow webmasters to specify that one page should rank higher than another on their own site. The only way to signal the importance of a page is through internal linking: strongly linki...
John Mueller Aug 21, 2020
★★★ Should you really index all paged pages to optimize your SEO?
For pagination, all pages should be indexable if they contain important content or links. They must be connected with standard HTML links (next/previous). Google can crawl and index these pages withou...
John Mueller Aug 21, 2020
★★★ Should you really add nofollow to footer links between sites of the same group?
If sites belong to the same company, there's no need to add the nofollow attribute to cross links in the footer. Google recommends linking primarily by brand name. For a handful of sites, it's no prob...
John Mueller Aug 21, 2020
★★ Can a hacked site lose its crawl budget due to Google security alerts?
A hacked site with malware or phishing reported in Search Console will not see its crawl reduced. The impact is on display in the search results (warnings, filtering), not on the frequency or intensit...
John Mueller Aug 21, 2020
★★★ Do site-wide links in the menu and footer really dilute the PageRank of your strategic pages?
Having multiple site-wide links to the same page (for example, in the menu and footer) does not significantly dilute the PageRank passed to other pages. Google understands that certain pages, like the...
John Mueller Aug 21, 2020
★★ 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...
