An on-page SEO checker for the page you're already on
Hoverify is an SEO audit extension that checks Core Web Vitals, meta tags, heading structure, images, links and schema from a panel on the page you're auditing. No crawler queue, no pasting URLs into four different sites, and it works on staging behind a login.
Everything an on-page SEO audit should cover
Lighthouse, metadata, structured data, headings, images and links, all checked from a single panel.
The checks, in the order you'd run them
Most on-page problems are dull and fixable. The work is finding them, which is why each check lives in its own tab instead of one long scroll of warnings.
Title, description and the social tags, each measured against the length search engines actually show. Canonical, robots and viewport get checked too, which is usually where the surprise is.
The full H1 to H6 outline, with duplicates, empty headings, second H1s and skipped levels called out where they happen. Easier to read than scrolling the DOM and counting.
Every internal and external link, filterable by type including no-follow, with status codes that come from a real request rather than a guess. Anchor text sits next to each one.
JSON-LD, Microdata and RDFa detected and validated, so an invalid block is visible rather than silently ignored. Nothing on the page? Generate it from a template and copy it out.
Lab scores and real user data
Lighthouse numbers from Google's PageSpeed API, plus Core Web Vitals from the Chrome UX Report, which is what actual visitors experienced rather than what a test machine measured. Mobile and desktop are reported separately, because they rarely agree.
Images, measured rather than eyeballed
Missing alt text, unmarked decorative images and files whose original dimensions dwarf the size they're rendered at. That last one is where most of a page's wasted bytes are hiding.
Export the whole audit as one report
One click turns the whole audit into a single document you can save and send, instead of screenshotting each tab in turn.
Every check, one document. All the checks land in one file, laid out the way you read them.
Tells you what to fix. Every section marks what's passing and what needs work, so the report reads like a to-do list.
Ready to hand off. Save it as a PDF or HTML file and send it straight to a client or teammate.
Works behind a login. Audit staging, a members area or a checkout. Everything but the Lighthouse scores, which need a public URL.
21 schema templates. Organization, Product, FAQ, Article, Event and Breadcrumb among them, ready to fill in.
Copy anything out. Send the meta tags, the heading outline or the schema straight to your clipboard.

love this extension, latest update had a minor bug but was fixed very quickly by dev. Has been super reliable for us at nearly a daily use.

Incredible app for web designers! Wow!! I'm really impressed, it combined a ton of other tools I was using. So happy I found this.
Frequently Asked Questions
Have a question we haven't answered? Get in touch.
What does the SEO checker actually check?
Six things, each in its own tab: Insights, Meta, Headers, Images, Links and Schema. That covers Lighthouse scores and Core Web Vitals, meta and social tags, the H1 to H6 outline, image weight and alt text, every link on the page and structured data. It runs on whichever page you have open, including pages behind a login that a crawler can't reach.
Where do the performance scores come from?
Google's PageSpeed Insights API for the lab scores, and the Chrome UX Report for field data from real Chrome users. You get Performance, Accessibility, Best Practices and SEO, with separate mobile and desktop results. Both of those sources need a publicly reachable URL, so the Insights tab is the one part of the audit that can't run on a staging site.
Can it find broken links?
Yes. It lists every internal and external link on the page, filters by type including no-follow, and checks status codes with a real request so a 404 shows up as a 404. Anchor text is listed next to each link, which is where thin, generic wording usually shows up.
Does it help with structured data?
It detects JSON-LD, Microdata and RDFa already on the page and validates what it finds. If there's nothing there, you can generate markup from 21 templates covering Organization, Product, FAQ, Article, Recipe, Event, Breadcrumb and more.
Can I hand the audit to a client?
Yes. Export it as a PDF or HTML report in one click. Every section marks what's passing and what needs work, so it reads as a to-do list rather than a data dump. You can also copy just the meta tags, headings or schema to your clipboard.
Does it work in Firefox?
Yes. Every tool runs in the Firefox build; it carries an experimental label because Chromium gets fixes and new features first. Chrome is the fully supported browser, along with Chromium forks like Edge and Brave.
Is the SEO audit extension free?
The SEO panel comes with Hoverify, a paid extension with a 14-day refund behind it. A couple of real audits will tell you whether it stays, and you can get your money back if it doesn't. That stands in for a trial. One license runs in 3 browsers at a time, and nothing auto-renews. See the pricing.
Audit the page, then fix it in the same tab
Hoverify keeps the SEO checks next to the CSS inspector, Site Stack and the screenshot tools. Find the heading that's wrong, edit it in place to see how it reads, and export the report when you're done.
- 3 browsers per license
- 14-day refund
- No auto-renewal
