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.

★★★ Does a 302 redirect really cause you to lose PageRank compared to a 301?

★★★ Why do domain mergers and divisions trigger extended SEO ranking swings?
During domain mergers or divisions, Google must reevaluate page importance and internal linking structure, which leads to long-term ranking fluctuations. These changes are more complex than a simple d...

★★★ Do you really need bidirectional redirects between mobile and desktop versions to avoid indexing issues?
For sites with separate mobile and desktop versions, you must implement redirects in both directions: mobile to m.domain.com AND desktop to www.domain.com. Without this, Google assumes everything is o...

There are important differences between crawlers and browsers, even when using the same user agent. Crawlers don't support certain features like cookies, which can create different experiences....

★★ Does Google really refuse to index your templated content, and why should you care?
Google does not guarantee indexing of content created from templates, even if it is submitted. If very similar pages are not indexed, you must differentiate key elements such as H1 tags....
