What does Google say about SEO? /
The Images & Videos category compiles all official Google statements regarding visual content optimization for search engine optimization. This area encompasses recommendations on image alt attributes, modern formats like WebP, lazy loading implementation, srcset usage for responsive images, and optimization of thumbnails and embedded YouTube videos. Google's positions on these topics are crucial as visual content represents a major lever for enhancing user experience, reducing page load times, and increasing visibility in Google Images and universal search results. SEO practitioners will find clarifications on EXIF data handling, image indexing processes, best practices for naming visual files, and the impact of Core Web Vitals on media performance. Understanding official guidelines helps avoid common implementation mistakes, optimize crawl budget allocated to visual resources, and maximize organic traffic opportunities from image and video search. This documentation centralizes essential technical and editorial recommendations for an effective visual content strategy that aligns with Google's ranking factors and supports overall site performance in search results.

★★★ Is measuring only the LCP a strategic mistake for your SEO?

★★ Why does Google differentiate between crawl speed and user speed?

★★★ Why does Google ignore your canonical tags when the raw HTML contradicts the rendered output?

★★ Can the Mobile-Friendly Test really substitute the URL Inspection Tool for auditing mobile crawling?
The Mobile-Friendly Test always uses the mobile crawler and can serve as an alternative to test what the mobile Googlebot sees, especially for sites not yet migrated to mobile-first indexing where the...

★★★ How can a different canonical tag between raw HTML and rendered output destroy your canonicalization strategy?
Having a different canonical tag in raw HTML and rendered HTML sends conflicting signals to Google. This can weaken the canonical signal and lead Google to choose a completely different URL or alterna...

★★ Does Google really overlook your images during web search rendering?
Google does not necessarily fetch images during the rendering for main web search. Images are retrieved by Google Images, which has its own system. Google recognizes the existence of the image, its al...

★★ Should you be worried about 'other error' issues with images in the Search Console?
In the URL inspection tool, 'other error' issues for images or resources like tracking pixels are normal. Google Search does not directly extract images (that's Google Images' job) and does not need t...

★★ Why does Google crawl your image URLs without extensions twice before indexing them?
If Google cannot recognize that a URL points to an image (due to the absence of an extension), it will first attempt to crawl it for traditional web search, fail, and then potentially treat it as an i...

★★★ Should you really make all structured data images visible on your pages?

★★★ Do Core Web Vitals Really Take 28 Days to Impact Your SEO Rankings?
John Mueller explained in a webmaster hangout that Core Web Vitals "scores" (LCP, CLS, FID) would not be calculated in real-time (unlike filters such as Panda or Penguin, for example) starting next Ma...

★★★ Why Does Google Ignore CSS-Displayed Images for Indexing Purposes?
John Mueller reminded us on Twitter that Google only indexes an image if it is displayed using an <img> tag. Images displayed via CSS (particularly background images) are not taken into account, nor a...

★★★ Does switching CMS really destroy your organic search rankings?
Switching CMS (e.g., from Squarespace to WordPress) will likely affect your ranking, positively or negatively depending on the quality of the migration. Google does not only look at text but at everyt...

★★ Why does Google display incomplete SERPs when some indexes don’t respond?
