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helping SEO specialists make informed strategic decisions based on verified information rather than speculation or outdated assumptions about temporal ranking factors.

★★ Should you really worry about the impact of 404 redirects on your crawl budget?

★★★ Is it really necessary to translate your content to rank in another language?
A site entirely in one language (e.g., Marathi) will generally not be displayed for queries in another language (e.g., English). Exception: in some countries where local content is lacking, Google may...

★★ Can 301 redirects to fix broken URLs lead to a Google penalty?
Fixing problematic old URLs with 301 redirects is a best practice that improves the site. It is never considered spam. If a ranking drop coincides with these corrections, it is probably independent an...

★★ Are category pages with product snippets really free from duplicate content penalties?
An indexed category page containing product snippets is not considered problematic duplicate content. Duplicate content is normal on the web and does not penalize a site. Google simply seeks to determ...

★★★ When it comes to duplicate content across two sites, does Google really impose penalties or not?
Google does not automatically penalize when a business operates two distinct websites with identical content (e.g., a main site + a site dedicated to a specific section). The two sites are treated ind...

★★ Is it true that your thousands of subdomains slow down Google’s crawling?
When a site uses thousands of subdomains, Google's crawling systems may take time to adapt because they are optimized by hostname. Initially, Google must determine whether all these subdomains share t...

★★ Why do link aggregators struggle to rank effectively?
Sites that primarily function as collections of links to other providers (for example, app or sports betting aggregators) may encounter ranking difficulties because Google’s algorithms may prefer to i...

★★★ Is page speed really just a secondary ranking factor in Google?
Google refutes the claim that page speed is the most important ranking factor. While speed is a factor to consider, it is not the primary criterion for ranking....

★★★ Why does your massive no-index take 6 months to a year to be processed by Google?
Adding no-index to millions of old pages takes time (6 months to 1 year) to be fully processed. Google prioritizes crawling new important pages, even though, in absolute volume, it still crawls many o...

★★ Why do your review snippets seem to disappear and then reappear every week?
Weekly or monthly activations/deactivations of review snippets suggest a technical issue or algorithmic hesitation. This is not normal behavior. It's essential to share the URLs in the forum or with t...

★★★ Is Google really tolerant of technical cloaking?
Serving slightly different content to Google and users (e.g., cached data vs live) is not considered spammy cloaking if the purpose of the page remains the same. The main risk is technical (errors inv...

★★ Do you really need to optimize internal link anchors, or is it a waste of time?
For two strong pages on the same topic (e.g., e-commerce and guide), using the same natural anchor (e.g., 'cheese') for internal links is acceptable. There's no need to over-optimize anchors by adding...

★★ Should you abandon onclick to avoid being penalized for cloaking?
Having a link with href and an onclick handler that prevents the default action and updates the current page's content is not considered cloaking, as long as the displayed content meets expectations a...

★★ Is it really necessary to avoid duplicate meta tags in HTML and JavaScript?
Having duplicate meta tags (for example, in index.html and via React Helmet) is problematic. You need to either remove them from the static HTML file and generate them solely through the JavaScript fr...
Martin Splitt Jun 23, 2020
★★★ Should you really use unavailable_after to manage past events on your site?
For an events site, using the unavailable_after meta tag allows you to indicate to Google when a page will become outdated. This helps Google avoid crawling these pages after expiration and focus on n...

★★★ Does unsupported structured data really affect ranking?
Building a network of structured data between pages with types unsupported by Google has no visible effect on ranking. Google primarily uses the types documented in its developer guide. The rest is ei...

★★ Do you really need to stick to the supported page types for the reviewed-by schema?
The reviewed-by markup can only be used on officially supported page types (e.g., Medical Page). If schema.org does not allow it to be added to NewsArticle, you should not force a non-compliant implem...

★★ Does mobile-first indexing really improve your ranking in Google?
Being migrated to mobile-first indexing brings no ranking or search advantage. It is simply the way Google indexes the site. There is no urgency to force this migration....

★★★ Why does Google crawl your JS/CSS files but never indexes them?
Crawling involves making an HTTP request and retrieving the result. Rendering executes the crawled JavaScript in a browser to produce the content. Indexing stores useful content to display to users. J...
Martin Splitt Jun 23, 2020
★★★ Is Google really confusing your local pages with duplicates because of URL patterns?
Google can make mistakes with canonicalization if the systems determine that a part of the URL (e.g., city name) is irrelevant, especially if random names do not generate a 404. This leads to incorrec...
