What is an image SEO audit?
An image SEO audit reviews how website images are described, delivered, discovered, indexed, and rendered. It can include alt text, filenames, dimensions, formats, compression, responsive images, loading behavior, structured data, and image accessibility.
How do I perform an image SEO audit?
Start by inventorying important images, then check alt text, filenames, file sizes, dimensions, formats, responsive delivery, loading behavior, image accessibility, crawlability, and page performance.
Does alt text help SEO?
Useful alt text helps provide an accessible text alternative for images and can provide search engines with additional context about meaningful images. It should describe the image rather than be used for keyword stuffing.
Should every image have alt text?
Meaningful images generally need appropriate alternative text. Decorative images can use an empty alt attribute so assistive technology can skip them. The correct implementation depends on the image's role.
How do I optimize images for SEO?
Use accurate alt text, descriptive filenames where practical, appropriate dimensions, efficient formats, compression, responsive image delivery, suitable loading behavior, and relevant surrounding content.
What image format is best for SEO?
There is no single format that is best for every image. WebP and AVIF can provide efficient delivery in many cases, while JPEG, PNG, SVG, and other formats remain appropriate for particular image types.
Should I lazy load all images?
No. Lazy loading can help defer images outside the initial viewport, but important above-the-fold images should be loaded appropriately rather than automatically deferred.
How can images affect Core Web Vitals?
Images can affect loading performance and visual stability. Large or poorly delivered images can contribute to slower LCP, while missing dimensions can contribute to layout movement measured by CLS.
How do I optimize images for Google Images?
Make images accessible to crawlers, use relevant surrounding content, provide useful alternative text where appropriate, use descriptive image information, avoid unnecessary technical restrictions, and ensure the page containing the image is useful and accessible.
Do image filenames affect SEO?
Descriptive filenames can provide useful context about an image, but filenames are only one part of image understanding and do not independently determine search rankings.
Should I use an image sitemap?
Image sitemaps can be useful for websites with large or important image collections, particularly when additional image discovery support is valuable. They should complement, not replace, crawlable page implementation.
Can image SEO guarantee higher rankings?
No. Image optimization can improve accessibility, performance, discoverability, and context, but search visibility depends on many factors and no image SEO technique guarantees a particular ranking.
