Frequently Asked Questions (FAQ)

Why is this tool free?

This tool was built as a passion project to help website owners, bloggers, and marketers quickly diagnose common but impactful image SEO issues.

Is it safe? Do you store my data?

100% safe. The audit happens entirely in your browser using a public proxy. Your URL and your website data are never stored on our servers.

Why did my audit fail with a "Could not fetch URL" error?

This is the tool's most common issue and usually means the target website is protected by an anti-bot service like Cloudflare. These services block automated requests from proxies like the one our tool uses. Unfortunately, there is no workaround for this in a browser-based tool. It is not a bug, but a security feature of the website you are trying to audit.

How do I use the "Find on Page" button?

1. Click the button to copy a unique CSS selector. 2. Go to the original webpage and open Developer Tools (F12). 3. In the "Elements" tab, press Ctrl+F (Cmd+F) and paste the selector to instantly highlight the image.

Why were no tags found?

This can happen if images are loaded via JavaScript after the page loads, or if they are CSS background images. This tool specifically audits standard HTML tags, which are most critical for SEO.
