Image Alt Attribute Checker – turn images into SEO and accessibility wins

Use this Image Alt Attribute Checker when you want to see, in one scan, which images on a key landing page are missing alt attributes, using empty alt text or relying on weak, one-word descriptions. Paste the URL of a category page, product listing or blog article and the tool will crawl the HTML, count all <img> tags and highlight where you are losing accessibility and SEO opportunities.

This is especially valuable for ecommerce and content-heavy sites, where descriptive alt text can support long-tail rankings and screen reader users at the same time. Run the check, fix the missing or poor alt texts in your CMS or templates, then upgrade to the SEO Expert plan to combine this with full on-page audits and continuous monitoring of your most important money pages on SEOcheck.hu.

You can paste any public page URL. The tool will fetch the HTML, scan all <img> tags and report how many images are missing alt attributes, how many use empty or very short alt text and which ones might be too long to be practical.

Best practices for image alt attributes

Write alt text for context, not for stuffing keywords

Good alt text briefly describes what is important about the image in the context of the page. Avoid generic labels or keyword lists — instead, explain what a user who cannot see the image should understand from it.

Prioritise key templates and money pages

Start by fixing alt attributes in templates that power many URLs, such as product cards, category grids and featured article blocks. This way a single template update can improve hundreds of pages at once.

Combine alt text optimisation with internal linking

When images are also links, make sure link anchors and alt text together send a clear signal about the topic of the target page. This helps both accessibility and long-term organic visibility for critical sections of your site.
