Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
1.6
GPA, above 0 of the 34 other SEO browser extensions we grade
SerpWorx is a Chrome extension that puts a bar of SEO metrics under each result on a Google search page, and shows the same figures for any site you visit. It pulls link and authority metrics from Majestic, Moz, Ahrefs and Semrush and adds its own on-page checks such as word count, headings and broken links. It is a paid subscription with a 3-day free trial.
To get you started, here are 8 things to know about SerpWorx, taken from its own pages and our grades.
It's a subscription to sign up for, and the Ahrefs figures only appear if you have your own Ahrefs account.
- 1
Best for Majestic, Moz and Semrush figures on Google results
SerpWorx puts a bar of Majestic, Moz, Semrush and Ahrefs figures under every Google result and on any site you open, with word counts, headings and broken links alongside.
- 2
Paid plans start at $29.95 a month
As its pricing page puts it: $29.95 per month.
- 3
You can try it first
3-day free trial, no credit card needed
- 4
Metrics bar in search results
Shows a bar of SEO metrics under every site in Google's results for the keyword you searched, so ranking pages can be compared side by side.
- 5
Majestic and Moz metrics
Trust Flow, Citation Flow and Topical Trust Flow from Majestic, and Domain Authority, Page Authority and Spam Score from Moz, with inbound link counts.
- 6
Ahrefs and Semrush data
Ahrefs URL Rating, Domain Rating, link counts and anchor text density, which need your own Ahrefs account, plus Semrush keyword visibility and monthly traffic.
- 7
A 1.6 GPA, above 0 of 34
That is against the other SEO browser extensions we grade, on value, the free plan, features, ease of use and platforms.
- 8
Keep it
To replace SerpWorx you would be making an index of the links between billions of web pages. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for Majestic, Moz and Semrush figures on Google results
SerpWorx puts a bar of Majestic, Moz, Semrush and Ahrefs figures under every Google result and on any site you open, with word counts, headings and broken links alongside. It's $29.95 a month after a 3-day trial, the dearest on record in a category where most tools are free, the Ahrefs figures need your own Ahrefs account, and its plan limits couldn't be confirmed.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | D | $29.95 a month, per its Chrome Web Store listing, which is where this category's dearest tenth starts. 19 of the 22 tools here are free outright, and the Ahrefs figures still need a separate Ahrefs account. |
| Free plan and trial | D | No free plan. The trial needs no card but lasts 3 days, under a week, and then it's $29.95 a month. |
| Features | C | Majestic Trust Flow, Moz Domain Authority and Spam Score, Semrush traffic, Ahrefs ratings, word and heading counts, keyword frequency, broken links and a mobile check. No title, meta or schema checks are on record, and the Ahrefs part needs your own account. |
| Ease of use | C | No rating on record. It's a subscription to sign up for, and the Ahrefs figures only appear if you have your own Ahrefs account. |
| Platforms and integrations | C | Chrome only, so computers only, with no Firefox add-on found under its name. It pulls figures from Majestic, Moz, Ahrefs, Semrush and the Wayback Machine. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who SerpWorx is for
- Fits if you size up the pages ranking for a keyword before writing for it
- Works for comparing Majestic, Moz and Semrush figures in one place
Who it is not for
- Pricey if you're one person, at $29.95 a month where most extensions here cost nothing
- Tight if you want to try it properly, as the free trial lasts 3 days
- Watch out: its own pricing page couldn't be read, so usage limits and any team plans are unconfirmed
- Skip it if you don't pay for Ahrefs, since the Ahrefs metrics need your own account
- Not for you if you're not on Chrome, as no Firefox version was found
Good to know

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace SerpWorx you would be making an index of the links between billions of web pages. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 34 of the 34 other SEO browser extensions grade higher. It costs $359.40 a year.
What you could not
- An index of the links between billions of web pages.
- A crawler that checks every page of a site.
- Speed tests run from real browsers on a schedule.
- It plugs into other products, Majestic, Moz and Ahrefs among them.
What this rests on. SerpWorx’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
