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helping SEO specialists make informed strategic decisions based on verified information rather than speculation or outdated assumptions about temporal ranking factors.

★★ Are iFrames really crawled by Google, or should you avoid them for SEO?

★★★ Does the cached page truly reflect what Google indexes?
The cached page is a technical copy of the fetched HTML, not a representation of what is actually indexed. To check indexing, use the URL Inspection Tool. JavaScript may not execute on cached pages as...

★★ Are structured data on noindexed pages really lost to Google?
Google probably does not take into account structured data on pages marked noindex, as the processing halts before it analyzes the structured data. Regarding link extraction, it can happen in parallel...

★★★ Does Google really render all JavaScript pages, regardless of their architecture?
Google renders virtually all pages. The fact that part of the content is rendered on the server and another on the client does not influence Google's decision to render the page or not. There is a heu...

★★★ Is it true that Google ignores JavaScript rendering if your noindex tag appears in the initial HTML?
If a page contains a meta robots noindex tag in the initial HTML, Google will not render the page, even if JavaScript later modifies that directive. Google considers that the page does not want to be ...

★★★ What does Google really do with your initial HTML before JavaScript rendering?
Google performs an early extraction of links from the initial HTML to queue them, detects 404 errors, and analyzes meta tags (canonical, description, robots). If a noindex meta tag is present in the i...

★★ Could your deleted resources be harming your pre-render indexing?
When using cached pre-render solutions, it is essential to keep old versions of assets (JavaScript, CSS) available long enough to prevent the cached HTML from referencing resources that no longer exis...

★★★ Can blocking JavaScript really stop Google from indexing all the content on your pages?
If JavaScript code blocks the rendering of part of the page and never completes its execution, Google will stop rendering. The content that this JavaScript was supposed to load and any following HTML ...

★★★ Could a 404 page with JavaScript lead to the complete deindexing of your site?
If a page returns an HTTP 404 status code, Google treats it as an error even if JavaScript would subsequently load content. Using a 404 page to load content via JavaScript leads to the complete deinde...

★★★ Does Google really index all pages after JavaScript rendering?
Contrary to popular belief, there aren't really two ways to index. Google processes the initial HTML, then decides to render the page, and then indexes it. Almost 100% of pages are rendered before bei...

★★★ Do Web Stories really follow the same SEO rules as your regular pages?
Web Stories are normal HTML pages. As a result, everything learned about SEO also applies to Web Stories. The Web Creators team has released a specific video on SEO for Web Stories....

★★★ Why does Google display empty pages even when your JavaScript site is working perfectly?
If a JavaScript request to an API (like /api/cats) is blocked by robots.txt, Googlebot will not be able to load it even if it works in browsers. Browsers ignore robots.txt, but Google respects it, whi...

★★★ Is Google Indexing Really Under Control with a Sitemap and Internal Links?
Google strongly recommends using the usual methods to help search engines find and index content: ensuring the site is properly accessible, that it contains prominent links to new pages, and using sit...

★★ Should we stop optimizing for bots and focus solely on the user?
Google does not provide a specific range of time or CPU measurements because these are implementation details that can change. The recommendation is to optimize for speed and minimize CPU resources as...

★★★ Does Page Experience really change how websites rank on Google?
The Page Experience ranking factor, including Core Web Vitals, will be active in Google Search starting May 2021. Although there is still time, it is recommended to act quickly as improving site speed...

★★★ Does Google really render ALL JavaScript, even without initial server-side content?
Google renders practically all JavaScript pages. The presence of initial server-side content does not influence the decision to render or not render a page's JavaScript. A heuristic exists for certain...

★★★ Why does Google refuse to render JavaScript if the initial HTML contains a meta noindex?
If a noindex robots meta tag is present in the initial HTML, Google will not render the JavaScript page because the instruction already indicates that the page does not want to be indexed. Be careful ...
