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age, helping SEO specialists make informed strategic decisions based on verified information rather than speculation or outdated assumptions about temporal ranking factors.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 hreflang in HTML really weigh down your pages, or is that just a myth?

★★★ Does Google really rewrite your meta descriptions if they contain too many keywords?

★★★ Why does your hreflang markup still not work despite your efforts?
For hreflang to work, Google must see the markup on both linked pages. If an English page points to a Spanish page, the Spanish page must also point to the English page. If the language versions are i...

★★★ Does the URL removal tool truly deindex your pages?
The URL removal tool in Search Console hides URLs from search results but does not immediately remove them from the index. They continue to be counted in the Index Coverage report until Google fully r...

★★ Does Google Images really select the right image for your pages?
To ensure Google Images associates the right image with a page, integrate main images visibly and use structured data (e.g., article markup) to explicitly specify which images represent the page. This...

★★★ Is the site: command really useless for diagnosing indexing?
The number of results displayed by the site: command is optimized for speed, not accuracy. To diagnose indexing, one must rely on the Index Coverage report from Search Console, which accurately reflec...

★★ Does mixed content HTTPS/HTTP really impact Google rankings?
Mixed content (HTTP within a HTTPS page) does not impact ranking, but Chrome displays a security warning because it may expose session information. It is recommended to clean up these HTTP URLs, for e...

★★ The 50,000 URLs in a sitemap: why does this limit not mean what you think it does?
The limit of 50,000 URLs in a sitemap applies only to the main URL tags (loc tag), not to additional attributes like hreflang, images, or videos. There is also a file size limit. You can create multip...

★★★ Why does Google refuse to index all your pages, and how can you fix it?
Google does not promise to index all pages on the web. On a new site with a sudden influx of content, systems may be cautious and limit crawling and indexing. Submitting via Inspect URL does not guara...

★★★ What happens when your internal linking isn't bidirectional?
For Google to crawl the entire site, it requires links that allow for descending through the hierarchy (to subcategories), ascending back up, and navigating horizontally between items in the same cate...

★★★ Is it true that BERT penalizes websites that lose traffic after its rollout?
BERT is not a ranking algorithm update but a system to better understand the text of long queries and pages. If a site loses traffic after BERT, it's because Google has a better understanding of what ...

★★ Does Google Tag Manager really slow down your site, and should you abandon it?
Google Tag Manager is a viable solution when developer resources are lacking, but it adds extra JavaScript and impacts speed. If you can implement directly on the page or with your own JavaScript, it'...

★★ Does the JSON application state in the DOM create duplicate content?
During server-side rendering, if the application state is serialized as JSON in the page (for hydration) in addition to the rendered HTML, it does not pose a duplicate content issue. Google only looks...
Martin Splitt May 12, 2020
★★★ Is it really time to move on from dynamic rendering for SEO?
Google is no longer actively recommending dynamic rendering (like Rendertron). It's a workaround, not a long-term solution. If JavaScript causes issues for Googlebot, it's likely causing issues for us...
Martin Splitt May 12, 2020
★★★ Is page speed really a Google ranking factor?
Page speed is already a ranking factor, and that won't change. Google uses metrics that model user experience to determine what constitutes a good response to a query. The Web Vitals (LCP, CLS, FID) a...

★★★ Can you really inject the canonical tag via JavaScript without risking your SEO?
It is acceptable to inject the canonical tag via JavaScript, even if the script is in the footer. The important thing is that in the rendered HTML, the canonical tag appears in the head and is the exp...

★★ Is serving a 404 to Googlebot while showing a 200 to visitors really cloaking?
In a pre-rendered React SPA, serving an HTTP 404 code to Googlebot (via pre-render) while the user sees a 200 error page is generally not considered cloaking, unless you are doing something really dub...
Martin Splitt May 12, 2020
★★★ Does Googlebot really ignore your WebP images served through Service Workers?
Googlebot does not execute Service Workers. If a site uses a Service Worker to serve WebP images instead of JPEG/PNG, Googlebot will only see the original formats (JPEG/PNG), not the WebP. This does n...

★★★ Do Lighthouse and PageSpeed Insights really have no impact on rankings?
Lighthouse and Page Speed Insights are tools for developers and SEOs, not direct ranking factors. They model user experience in terms of loading speed and are constantly evolving. These tools help det...

★★ Does serialized JSON in your JavaScript apps count as duplicate content?
During SSR, application state is often serialized in JSON on the page, which duplicates the content once in the JSON and once in the DOM. Google does not consider this problematic duplicate content be...
