Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.8
GPA, above 4 of the 34 other SEO browser extensions we grade
MeasureSEO is a free Chrome extension that lists the words and phrases used most on the page you are viewing, with how often each appears and its share of the page's total words. Phrase length, minimum counts, stop words in more than 25 languages and excluded words can be set, and results export to CSV. The same site offers a web version for pasted text and other small SEO utilities.
To get you started, here are 8 things to know about MeasureSEO, taken from its own pages and our grades.
No rating on record, but nothing to set up: open the popup on a page and the table is there, with no account.
- 1
Best for keyword density on the page you're reading
MeasureSEO counts the words and phrases on the page you're viewing and gives each one's share of the total, with stop words in 25+ languages and CSV export, free and without sending the text anywhere.
- 2
It is free
MeasureSEO has no paid plan at all. The extension and the site's web tools are free, with no sign-up and no stated limits.
- 3
It runs on Web
Web, with a browser extension too.
- 4
Keyword counts and density
Lists every keyword on the page with how many times it appears and its percentage of the total word count, shown above the table.
- 5
Phrase length and minimum count
Switch the table between single words and longer phrases, and hide terms that appear fewer times than a set minimum.
- 6
Stop words in 25+ languages
Stop words are removed by default using lists in more than 25 languages, and you can add your own stop words or excluded words.
- 7
A 2.8 GPA, above 4 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
MeasureSEO is free, so making your own would save you nothing.

The report card
Best for keyword density on the page you're reading
MeasureSEO counts the words and phrases on the page you're viewing and gives each one's share of the total, with stop words in 25+ languages and CSV export, free and without sending the text anywhere. It only counts words: no search volumes or rankings, pages built mostly with JavaScript are harder for it, and the extension hasn't been updated since December 2023.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | Free, with no sign-up and no stated limits, and the site's other web tools are free too. |
| Free plan and trial | A | Free outright: counts, density, phrase lengths, stop-word lists, excluded words and CSV export, with nothing to upgrade to. |
| Features | D | One narrow function: keyword counts and density for one page, with phrase length, minimum counts and stop words in 25+ languages. No search volumes, rankings or other page checks. |
| Ease of use | B | No rating on record, but nothing to set up: open the popup on a page and the table is there, with no account. |
| Platforms and integrations | C | A Chrome extension plus a web version for pasted text, with no integrations. The site adds robots.txt, meta tag, sitemap and UTM generators. |
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 MeasureSEO is for
- Fits if you check a draft or live page for a keyword used too often
- Works for writers on pages in languages other than English, with stop-word lists for 25+
Who it is not for
- Too light for keyword research, as it gives no search volumes or rankings
- Watch out: pages built mostly with JavaScript, such as forums and web apps, are harder for it to read
- Skip it if you're not on Chrome, and note the extension's last update was in December 2023
- Watch out: the developer hasn't identified itself as a trader, so EU consumer rights don't apply
Good to know
Good for
- Writers checking a draft or live page for keyword stuffing
- Seeing which terms a competitor's article repeats most
- Pages in languages other than English
Worth knowing
- Pages built mostly with JavaScript, such as forums and web apps, are harder to analyze, the listing says.
- It counts words on one page; it gives no search volumes or rankings.
- It is listed for Chrome only, and the listing was last updated on December 17, 2023.
- The developer has not identified itself as a trader, so EU consumer rights do not apply, as the store listing notes.

Part 04 · Standing
Where it stands
Its grades against its category, and whether to keep it or make your own
4/34
Other SEO browser extensions it is graded above
MeasureSEO's GPA of 2.8 is higher than 4 of the 34 other SEO browser extensions we grade, and level with 12.
It stands best on free plan and trial (A, above 5 of 34) and worst on features (D, above 0).
MeasureSEO has no paid plan.
On features, ease of use and platforms it scores 2.0 out of 4. Nothing scores higher for less, though at least one tool matches that score at a lower price.
Each grade against the category
Every bar is all 35 SEO browser extensions we grade, cut by the letter each got. MeasureSEO’s own letter is outlined.

Price against what you get
Each dot is one of 34 SEO browser extensions. Further left costs less; higher up scores better on features, ease of use and platforms. MeasureSEO is the marked dot.
What paid plans start at, a month (each step along is roughly double) →
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
MeasureSEO is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces. That makes this kind of software worth paying for, not this one in particular: 18 of the 34 other SEO browser extensions grade higher.
What you could not
- Search volumes for millions of keywords, gathered and kept up to date.
- A score built from what the top results for each keyword cover.
What this rests on. MeasureSEO’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.
