SEO Quick Scan: Ahrefs vs UtilitySEO Compared

An SEO quick scan checks a site for the problems that hold back rankings, without the time a full audit takes. This post compares how Ahrefs and UtilitySEO handle a quick scan and what each one is for. For a longer list of tools, see our guide to SEO quick scan tools.

What an SEO quick scan is for

An SEO quick scan answers one question fast: is anything on this page obviously broken? It is the check you run before a meeting, after a release, or on a prospect's site, not a full audit.

UtilitySEO's quick scan is free, needs no signup and takes about 30 seconds. It returns PageSpeed scores for performance, SEO and accessibility for the page you enter, plus a ranked list of what to fix first. Because it needs no access to the site, you can run it on any URL, including a competitor's. Try it on the free SEO scan page.

Ahrefs' nearest equivalent is Ahrefs Webmaster Tools, which is free but only works on websites you have verified you own. Its Site Audit checks for more than 170 common technical and on-page issues, with 5,000 crawl credits a month per project (checked September 2026). That makes it a good free option for auditing your own whole site, and no option at all for a quick look at someone else's.

Which to use: for a thirty-second check of any single page, an SEO quick scan. For every page of your own site, a full crawl: Ahrefs Webmaster Tools for free, or a paid crawler once you need scheduling and history.
