Image SEO Checker

Crawl a page or small website sample for missing alt attributes, dimensions, lazy loading, and image formats.

Public URLs are fetched securely with strict crawl and rate limits. Reports are not saved to your WordPress database.
Crawl the current page or up to 5 or 10 public pages, then review every image occurrence before updating markup or files.

Image SEO Checker

Find Image SEO Issues Across a Page or Small Site

WebTrendSEO’s Image SEO Checker crawls a public URL and reports image markup and delivery signals found on the selected page sample.

Enter a page or website URL, then choose the current page only, up to 5 pages, or up to 10 pages. The report distinguishes missing alt attributes from empty alt values and checks width and height attributes, WebP or AVIF usage, lazy-loading signals, and the source page for each occurrence.

The checker does not rewrite alt text, compress images, convert files, or edit your website. Empty alt text can be correct for decorative images, so review page context before making changes.

HOW IT WORKS

How to Use the Image SEO Checker

Choose a limited crawl scope, review each reported occurrence, and confirm the image’s purpose before updating it.
Enter a Public URL

Add the page or website address you want the checker to fetch.

Choose the Crawl Scope

Audit only the current page or sample up to 5 or 10 pages.

Run the Image Audit

Let the secure crawler collect image markup from the selected public pages.

Review Each Occurrence

Check alt status, dimensions, format, lazy loading, and source-page context.

Validate the Image Purpose

Decide whether an empty alt value is intentional and whether each recommendation fits the design.

Update and Retest

Make changes in your CMS or codebase, then run the checker again.

WHY USE OUR IMAGE SEO CHECKER?

Improve Image Markup Without Guesswork

Images can affect accessibility, page stability, loading behavior, and how clearly a page communicates its content. A manual review becomes difficult when the same image or template appears across several pages.

This checker keeps the scope intentionally small and shows the source page for each occurrence. Use that context to separate genuine issues from intentional choices, such as empty alt text on decorative images.

RESPONSIBLE PUBLIC CRAWL

A Limited Audit Designed for Public Pages

The checker fetches public URLs through a secure, rate-limited crawler and limits the audit to one, five, or ten pages. Its interface states that reports are not saved to the WordPress database.

Do not enter private staging URLs, login links, credentials, or pages containing confidential information. Large or authenticated site crawls require a separate auditing process.

Any Question?
An Image SEO Checker reviews image markup and delivery signals on public pages. WebTrendSEO’s tool reports missing and empty alt attributes, width and height attributes, modern image formats, lazy-loading signals, and the page where each image occurs.
Enter one public page or website URL, choose the current page or a sample of up to 5 or 10 pages, and run the audit. A secure, rate-limited crawler fetches those pages and organizes the image occurrences it finds.
A missing alt attribute means no alt attribute is present. An empty alt value uses alt=”” and can be appropriate for a decorative image that should be ignored by assistive technology. The checker reports the distinction, but you must confirm the image’s purpose.
It checks alt-attribute status, explicit width and height attributes, WebP or AVIF usage, lazy-loading signals, and the source page for each occurrence. It does not assess visual quality, compress files, or write replacement alt text.
The public tool audits only the selected one-, five-, or ten-page sample and can access only crawlable public HTML. It may not see images loaded after complex interactions, behind authentication, or blocked from the crawler. A sample is not a complete sitewide audit.
No. It does not edit HTML, rewrite alt text, resize or compress images, convert file formats, or change lazy-loading settings. Review the findings, update your CMS or codebase, and retest the affected pages.
