Fetches the live page and audits every <img> tag for alt text, file names and SEO signals.

📖How to Use the Image SEO Checker

  1. 1
    Enter the page URL

    Paste the URL of any live webpage and click Check Images. The tool fetches the page source via a server-side proxy and finds every img tag.

  2. 2
    Review the image audit

    Each image is listed with its source URL, alt text status (present, empty or missing), and the alt text value where it exists. Images are grouped by status for easy prioritisation.

  3. 3
    Fix and re-audit

    Add descriptive, keyword-relevant alt text to every content image. Decorative images should have empty alt attributes (alt="") so screen readers skip them correctly. Re-run the checker after fixing to confirm all issues are resolved.

Frequently Asked Questions

Why is image alt text important for SEO?

Alt text is the primary way search engine crawlers understand what an image depicts. Images without alt text are invisible to Google Image Search and contribute no keyword signals. Descriptive alt text with relevant keywords improves both image search rankings and overall page relevance signals.

What is the difference between missing alt and empty alt?

A missing alt attribute (img src="photo.jpg") means no alt attribute exists at all — this is both an SEO and accessibility failure. An empty alt attribute (alt="") is intentional: it tells screen readers to skip the image. This checker distinguishes between the two.

What should good alt text include?

Good alt text describes the image content clearly and concisely — typically 5–15 words. If the image supports the page topic, include the target keyword naturally. Avoid keyword stuffing and do not start with "Image of" or "Photo of".

How many images can this tool check?

The tool audits every img element found in the page source. Pages with dozens or hundreds of images (such as e-commerce product pages or image galleries) are fully supported with a scrollable, filterable results table.

Does the tool check image file names?

Yes — the tool shows the image filename from the src URL. A file named IMG_4827.jpg carries no keyword signal. Renaming it to blue-running-shoes-adidas.jpg tells search engines what the image shows and improves discoverability.

What are decorative images and how should they be handled?

Decorative images (dividers, backgrounds, icons used purely for visual effect) add no informational value. They should have empty alt attributes (alt="") so screen readers skip them. Adding keyword-rich alt text to decorative images is considered keyword stuffing.

Does image alt text help with WCAG accessibility?

Yes — WCAG 2.1 Success Criterion 1.1.1 (Non-text Content) requires that all non-decorative images have a text alternative. This means providing meaningful alt text for content images is a legal accessibility requirement for many organisations, not just an SEO best practice.
