What does Google say about SEO? /
Artificial intelligence is fundamentally reshaping search engine optimization and Google's algorithms. This category compiles Google's official statements regarding AI usage in search, including machine learning technologies, large language models (LLMs), and new generative search experiences like SGE and AI Overview. SEO practitioners will find Google's positions on how AI-generated content (ChatGPT, Gemini, Bard) impacts website rankings and organic visibility. Google has clarified its guidelines concerning artificial intelligence for content creation, distinguishing acceptable practices from manipulative techniques that violate search quality standards. Understanding these official declarations is crucial for adapting SEO strategies to algorithmic evolutions, particularly with the increasing integration of machine learning into ranking systems. This category also covers the impact of AI-generated answers in SERPs, E-E-A-T quality criteria applied to AI-assisted content, and recommendations for maintaining organic search presence in the era of generative search. Essential insights include how Google evaluates content quality regardless of production method, focusing on helpfulness and user value rather than creation process. A must-follow resource for staying ahead in modern search engine optimization.

★★★ Is it true that hidden CSS content is really indexed in a mobile-first manner?

★★★ Should you worry about a Google penalty when deleting content in bulk?

★★★ What URL structure should you choose to boost your international ranking?
For geo-targeting, Google needs to be able to clearly identify distinct sections of the site: ccTLD (e.g., .de, .fr), subdomains, or subdirectories configured in Search Console. For language targeting...

★★ Can you really merge multiple domains using Google's Change of Address Tool?
The Change of Address Tool could technically be set up to consolidate multiple domains into one, but that is not its intended use. It is designed to replace an old site with a new one (signal transfer...

★★ Do technical errors on a main domain really penalize its subdomains?
Technical errors (404s, structured data issues, speed problems, grammar) on a domain generally do not affect subdomains. Exception: if the main domain appears completely offline, Google can deduce tha...

★★ Can blocking JavaScript and CSS really hurt your SEO?

★★★ Should you unblock JavaScript and CSS in robots.txt for better SEO?
Blocking access to JavaScript and CSS files via robots.txt prevents Google from downloading these resources, which can cause rendering issues. If content is generated by JavaScript or if non-native la...

★★★ 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...

★★★ Should you really avoid having multiple pages for the same keyword?
Having multiple pages on the same topic (e.g., a transactional page and an informational page) is normal and acceptable. Google tries to show the most relevant page based on search intent. Cannibaliza...

★★★ Why is Google Discover more demanding than traditional search for showcasing your content?
Google Discover follows the Google News guidelines for eligibility. Since the content is shown to users who are not actively searching for it, the systems are more cautious. A decrease in visibility o...

★★★ 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...

★★★ Should you really prioritize every Search Console issue as a crisis?
The problems listed in Search Console do not all have the same level of criticality. An inability to index is critical, but speed issues are less urgent. It's necessary to evaluate the real impact on ...

★★★ Should you really ditch third-party tools to test the HTML rendering of your pages?
Google recommends using its official tools (Mobile-Friendly Test, Rich Results Test, URL Inspection Tool) rather than third-party tools to check the rendered HTML. These tools show exactly what the Go...

★★ Do flat URLs really hinder Google's understanding?
A very flat URL structure (with no clear folders or parameters) makes it harder for Google to understand which parts of the URL are relevant. Parameters (e.g., city=paris) allow Google to test by remo...

★★★ Is it true that Google delays mobile-first migration for some sites?
For a site not yet migrated to mobile-first indexing, check that the headings are correctly marked up (not just styled text) and that the number of images (especially thumbnails) is similar between de...

★★★ Why do 404 redirects to the homepage destroy crawl budget?
Redirecting 404s to the homepage (even with a 5-second meta-refresh) is confusing for users and Google. Google treats this as a soft 404 and will continue to crawl more. It’s better to serve a genuine...
