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age, helping SEO specialists make informed strategic decisions based on verified information rather than speculation or outdated assumptions about temporal ranking factors.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 archive out-of-stock products instead of leaving them marked as unavailable?

★★ Why does Google keep crawling your old 404 URLs?
Google continues to occasionally crawl old URLs that return 404, particularly if they had backlinks or were significant. This crawl is done at very low priority and does not block the crawl of new pag...

★★ Do outbound links that are 404 really harm the perceived quality of a page?
Having a few outbound links returning 404 on a page does not lead Google to consider the page as low quality or outdated. Google adds these links to the scheduler, and if some are 404, it’s not a prob...

★★★ Should you really index all your pagination pages?
You need to decide whether pagination pages should be indexed based on whether they are critical for discovering products. If products are well linked elsewhere on the site, pagination does not need t...

★★★ Do structured FAQs really help improve rankings on Google?
Structured FAQs do not improve a page's ranking; they merely allow for potential display with FAQ snippets in the results. It's not a matter of competitiveness in terms of ranking, but rather visibili...

★★★ Does Google really analyze the audio of your podcasts for SEO?
Google does not perform any textual analysis of podcast audio files to understand what is being said. If content is essential for SEO, it needs to be presented in text on the page, for example through...

★★ Why does Google still display old content in your meta descriptions?
Google adapts the snippets and descriptions based on the user's query, even if the content is no longer present on the page. This adaptation can persist for a few weeks after a content change before i...

★★ Why does Google sometimes show your old meta descriptions in the SERPs?
Even after updating the meta description, Google can temporarily show the old text in snippets if that content was previously on the page and considered relevant to the query. This typically normalize...

★★ Should you really delete your out-of-stock product pages to avoid a quality penalty?
Having hundreds or thousands of out-of-stock product pages can create a mass of low-quality content that doesn't attract attention. It's better to focus this content in a gallery or archive page so th...

★★★ Do out of stock pages really hurt your Google rankings?
Pages of products marked 'out of stock' or 'not available' tend to be ranked as soft 404s. When they slip into a soft 404 state, the page and its images disappear from search results....

★★★ Do 302 redirects really pass PageRank like 301 redirects?
Google treats both 301 and 302 redirects similarly when it comes to the transmission of SEO signals. Both types of redirects pass PageRank and other signals. The difference mainly lies in the choice o...

★★★ Are Core Web Vitals really the only speed criterion that counts for ranking?
For 'page experience' ranking, Google will rely solely on Core Web Vitals as the speed factor. Other performance metrics may be important for user experience but are not direct ranking factors....

★★★ Does the canonical tag really transfer 100% of PageRank without any loss?
When Google follows a canonical tag, all SEO signals including PageRank are transferred to the canonical URL. There is no loss of value when the canonical is used correctly....
John Mueller Oct 29, 2020
★★★ Why does blocking robots.txt prevent noindex from working?
You should not block noindex URLs in robots.txt, as this prevents Google from seeing the noindex directive, and these pages may stay indexed. Instead, use the URL Parameters Tool to reduce crawling of...

★★ Is it true that Google still indexes Flash content, or should everything be migrated to pure HTML?
Google indexes pages with Flash solely based on the visible HTML content in the rendered DOM, not content within Flash files. The removal of Flash from browsers should not affect site traffic as Googl...

★★ Does alternative text for images really enhance SEO?
The alternative text for images is mainly used for image search (Google Images) and for accessibility. It should describe what's visible in the image, not necessarily repeat the product description....

★★★ Does FAQ structured data really need to be 100% visible on the page?
The content of FAQ structured data must be visible word-for-word on the page. Algorithms check that the text is present to avoid promising something in the results that the user cannot find on the pag...
John Mueller Oct 29, 2020
★★ Should you sync visible and technical dates to enhance your crawl?
The date displayed on the page should reflect major changes to the main content, not minor modifications (comments, sidebar). Dates in the sitemap or structured data can indicate any HTML change to si...

★★ Is the URL Parameters Tool in Search Console a zombie or still useful for your SEO?
The URL Parameters Tool in Search Console is still operational and is recognized by Google, but display data has been at zero for a long time. A replacement tool is under development....

★★★ Does lazy loading really harm your content's indexing by Google?
