Reading Level Checker

Unsupported input

The tool may reject input that does not match the expected content, structure, or file type.

Fix: Confirm the tool input requirements and paste the correct type of data.

Incomplete values

Missing fields or partial content can block processing or produce weak results.

Fix: Provide the full required input before running the tool.

Copying placeholder content

Sample or placeholder values can lead to output that looks valid but is not ready for real use.

Fix: Replace placeholders with your actual values before relying on the result.

What User-Agent does Reading Level Checker send?

Reading Level Checker sends a User-Agent string that identifies itself honestly (DevFox bot) rather than impersonating Googlebot — spoofing UAs can get a site's access flagged. If a page blocks non-browser UAs, you'll see the block clearly reflected in the output.

Can Reading Level Checker check password-protected pages?

No. Reading Level Checker only makes anonymous public requests — it can't log in or carry session cookies. For auth-protected pages, use a headless browser in your own environment.

Does Reading Level Checker respect my robots.txt?

Yes. Reading Level Checker fetches and parses robots.txt before crawling a site and skips disallowed URLs by default. You can toggle off the check if you're auditing your own site and want to see every status code.

How often is the data in Reading Level Checker refreshed?

Reading Level Checker fetches live data on every request — there's no cached result between sessions. That means you always see the current state of a page, at the cost of a small delay while requests complete.

Can I use Reading Level Checker for competitor research?

Yes, for publicly accessible pages. Reading Level Checker only makes anonymous public requests, so the rules are the same as opening the page in a normal browser — if you can see it without logging in, the tool can inspect it.
