Alt text is the signal Google uses to understand and rank your images in search.
Search engines index alt text to understand image content. Without it your product photos, blog images, and hero banners are invisible to Google Image Search.
WCAG 2.1 requires meaningful alt text for all informative images. Sites without it face ADA compliance issues, especially e-commerce stores in the US and EU.
Google treats pages with many un-described images as lower quality. Missing alt text drags down the entire page ranking potential, not just image search results.
A typical WooCommerce store has 5 to 20 images per product. With 500 SKUs that is 10,000 or more potential missing alt tags, each one a missed ranking signal.
Three steps from URL to full fix, no plugin install required for the audit.
Paste any page or site URL. The checker crawls all image tags across your pages and extracts their alt attributes.
Within 30 seconds you see every image with filename, page location, and alt text status: missing, empty, or present.
Connect ImageSEO to your WordPress site and auto-generate accurate, SEO-optimised alt text for every missing image using AI.
Monitor your alt text coverage score over time. ImageSEO re-scans on a schedule and alerts you when new images are added without alt text.

Need more than alt text? Run a full image SEO audit that checks file naming, WebP conversion, lazy-loading, and structured data across your entire site.
Yes. The audit report showing every image URL, which page it was found on, and whether alt text is missing or empty is free with no account required. You only need to sign up (free plan available) to use the 1-click bulk-fix feature that writes and saves alt text to your WordPress media library.
A missing alt tag means the img element has no alt attribute at all. An empty alt means the attribute exists but contains nothing. Both are problems for SEO because Google gets no keyword signal, but empty alt is sometimes intentional for decorative images. The checker distinguishes both so you know exactly what to fix.
The free scan covers up to 200 images across your site. For larger sites such as WooCommerce stores and photography portfolios, ImageSEO paid plans scan unlimited images and can process and fix thousands in a single batch operation.
Yes, consistently. Sites using ImageSEO see an average 287% increase in image search impressions within 60 to 90 days of completing a full alt text audit and fix. The impact on overall page rankings is measurable, especially for e-commerce product pages where image content matches search queries.
The alt tag audit works on any website including WordPress, Shopify, Webflow, and custom HTML. However the 1-click bulk fix requires the ImageSEO WordPress plugin to write alt text directly to your media library. For non-WordPress sites, the audit report gives you the full list to fix manually or via your CMS API.
ImageSEO uses computer vision models trained on product, editorial, and web content imagery. The generated alt text describes what is in the image, including object, colour, and context, and incorporates your page focus keyword if set in RankMath or Yoast. You can review every generated alt before saving, or approve all in bulk.
ImageSEO processes approximately 3,000 to 6,000 images per hour depending on plan tier. A WooCommerce store with 12,400 product images completed a full alt text generation run in under 4 hours. Writing alt text manually at 1 minute per image would take 206 person-hours for the same job.
Yes. ImageSEO integrates with Polylang and WPML, generating alt text in the correct language for each translation. French product images get French alt text, German images get German, automatically based on the post language. This is especially important for image SEO in non-English markets where localised alt text improves rankings significantly.
