Mobile vs Desktop Parity

Google indexes mobile-first. If your mobile HTML is missing content the desktop has, you're invisible for half of what you wrote. This tool fetches the same URL with both a mobile and a desktop User-Agent and diffs everything that matters.

URL to check

Fetches the URL twice — once as a desktop Chrome, once as an Android Chrome (Googlebot-class mobile) — and diffs the HTML that gets returned.

Enter a URL

We'll fetch it with both UAs and diff them.
