Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.4
GPA, above 3 of the 34 other SEO browser extensions we grade
Checkbot is a Chrome extension that crawls a website from your own computer and tests its pages against more than 50 SEO, speed and security rules, such as broken links, duplicate titles, invalid HTML, redirect chains and missing security headers. The free version checks up to 100 URLs per crawl; the paid Professional plan raises that to 10,000 and adds localhost crawling and CSV and PDF exports.
To get you started, here are 8 things to know about Checkbot, taken from its own pages and our grades.
No rating on record, but nothing to set up: type a start URL and the crawl runs in your browser, with a help note on each problem it flags.

The report card
Best for crawling a small site for SEO problems in Chrome
Checkbot crawls a site from your own Chrome and checks its pages against 50+ SEO, speed and security rules, such as broken links, duplicate titles and redirect chains. The free plan stops at 100 URLs per crawl and shows ads, Professional is $10 a month on yearly billing, and it doesn't run JavaScript, so anything a script adds to a page goes untested.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | Professional is $10 a month billed yearly ($120), or $15 month to month, for one person on any number of devices. That's right on this category's cheaper-quarter line, though 30 of its 35 tools cost nothing. |
| Free plan and trial | C | Basic is free with unlimited crawls and sites, but it stops at 100 URLs per crawl and shows ads. A small brochure site fits; most blogs and shops won't, and exports and localhost crawls need Professional. |
| Features | C | Site-wide crawls scored on 50+ SEO, speed and security rules, crawl filters, single-page rechecks and, on Professional, PDF and CSV reports. The gap the listing names: it doesn't execute JavaScript, so content added by scripts isn't tested. |
| Ease of use | B | No rating on record, but nothing to set up: type a start URL and the crawl runs in your browser, with a help note on each problem it flags. |
| Platforms and integrations | C | Chrome only, so computers only; the FAQ says there's no Firefox or other browser version. No integrations or API are listed. |
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 Checkbot is for
- Fits if you check a site of under 100 URLs for broken links and bad markup before launch
- Works for developers testing a staging or localhost site, on the paid plan
Who it is not for
- Tight if your site runs past 100 URLs, as the free plan stops there and shows ads
- Watch out: it doesn't run JavaScript, so content added by scripts isn't checked
- Watch out: CSV and PDF exports, localhost and password-protected crawls all need Professional
- Pricey if you pay month to month, at $15 against $10 billed yearly, and a plan covers one person
- Not for you if you're not on Chrome, as the FAQ says there's no other browser version
Good to know
Good for
- Developers checking a site for broken links and bad markup before launch
- Freelancers auditing small client sites without a desktop crawler
- People new to SEO who want each problem explained
Worth knowing
- It runs only in Google Chrome; the FAQ says there is no Firefox or other browser version.
- The free plan stops at 100 URLs per crawl and shows ads; localhost crawls and exports need Professional.
- It does not execute JavaScript while crawling, so content added by scripts is not tested.
- A subscription covers one person; new customers can get a full refund within 14 days.

Part 03 · Features
What it does
Its main features, where it runs, what it works with and who makes it
1
Place it runs: Browser extension
Chrome extension that crawls a site for SEO, speed and security issues. Here is what it does, as its own site describes it, and what it covers: site audit, page speed.
The gap the listing names: it doesn't execute JavaScript, so content added by scripts isn't tested.
- Site-wide crawl
- Crawls hundreds of pages at once from a start URL and scores them against 50+ rules drawn from Google, Mozilla and W3C guidance.
- SEO checks
- Finds broken links, missing or long titles and descriptions, duplicate content, canonical problems, missing image alt text, temporary redirects and sitemap issues.
- Speed and security checks
- Flags redirect chains, unminified or render-blocking CSS and JavaScript and missing caching or compression, plus HTTPS, mixed content and security header gaps.
- Staging and localhost sites
- Crawling runs on your own machine, so the paid plan can test localhost, private-network and HTTP Auth password-protected sites.
- Crawl filters and quick rechecks
- Limit a crawl by subdomain, folder, depth, pattern or file type, and recrawl a single page to confirm a fix.
- PDF reports and CSV export
- The Professional plan exports problem lists to CSV in bulk and produces PDF summary reports for clients or teammates.

Keep it
Nothing Checkbot does is plain enough to make in a weekend. The 2 things listed below take a company.
That makes this kind of software worth paying for, not this one in particular: 31 of the 34 other SEO browser extensions grade higher. It costs $120 a year.
What you could not
- A crawler that checks every page of a site.
- Speed tests run from real browsers on a schedule.
What this rests on. Checkbot’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.
