What does Google say about SEO? /
Web performance has become an official ranking factor in Google's algorithm, particularly since the introduction of Core Web Vitals in 2020. This category compiles all official Google statements regarding loading speed optimization, performance metrics, and their impact on organic search rankings. SEO professionals will find Google's positions on key indicators such as Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), First Input Delay (FID), and Interaction to Next Paint (INP). Google regularly communicates about the importance of loading times, Time to First Byte (TTFB), cache optimization, and techniques like lazy loading. These official declarations help understand how Google truly measures user experience, which performance thresholds to prioritize, and how PageSpeed Insights integrates into a site's overall evaluation. For search practitioners, following Google's official recommendations on web performance is crucial to maintain or improve search rankings while delivering an optimal user experience that enhances conversion rates and visitor retention. Understanding Google's evolving stance on speed metrics enables webmasters to align technical optimizations with actual ranking signals rather than assumptions or outdated practices.

★★★ Is it really necessary to aim for a Lighthouse score of 100 to rank better on Google?

★★★ Should you really aim for 100/100 on PageSpeed Insights to rank well?
The PageSpeed Insights score is a set of metrics used to identify weaknesses, not a magic number to optimize to 100%. In the future, Google will rely on Core Web Vitals rather than this overall score....

★★ Does the FAQ schema work if the answers are hidden in an accordion?
For the FAQ schema, the content must be visible on the page. It is acceptable to display questions with expandable answers, but hiding the entire FAQ block would be problematic. The presence of visibl...

★★ Is it true that using nofollow on internal menu links can control PageRank?
To prevent signal transfer to certain internal menu links, using the nofollow attribute is appropriate. However, in most cases, it is not necessary to hide these links; a no-index on the destination p...

★★★ Does the crawl budget truly impact the rendering phase of your JavaScript pages?
The crawl budget affects not only the initial crawl but also the rendering, as Google needs to fetch additional resources (CSS, JavaScript, API). A poor cache can force Google to continuously re-downl...
Martin Splitt Jul 14, 2020
★★ Should you ditch POST for crawlable APIs and switch everything to GET?
Google cannot cache POST requests, leading to greater crawl budget consumption. For rendering APIs, use GET requests. GraphQL can be employed to reduce the number of requests, but only in GET mode....
Martin Splitt Jul 14, 2020
★★★ Does the crawl budget really boil down to the simple sum of two variables?
The crawl budget consists of two elements: crawl rate (the speed at which Google can crawl without overloading the server) and crawl demand (crawl frequency based on content change frequency and not i...

★★ How does content hashing in URLs truly enhance your crawl budget?
To optimize caching and crawl budget, use content hashes in file names (e.g., application.AEF3CE.js) instead of generic names. This allows Google to cache resources indefinitely, and only new hashes w...

★★ Why do your PageSpeed testing tools show contradictory LCP and FCP scores?
FCP and LCP do not necessarily happen simultaneously, especially on devices with slow CPUs or slow network connections. Lighthouse run locally can yield different results than PageSpeed Insights execu...

★★ How can you precisely identify the elements that degrade your Cumulative Layout Shift?
To identify the elements responsible for a poor CLS, you can individually block requests in the Network tab of Chrome DevTools and rerun the metrics, or use an automated Puppeteer script. Lighthouse 6...
