How do I start Checkbot?
After you’ve added Checkbot to Chrome, you should see a small Checkbot icon in the top-right of your browser window. When you click this icon, Checkbot will launch. You should see then see a prompt asking you which URL you want to start crawling from.
What operating systems does Checkbot run on?
Checkbot will run on any operating system that the Google Chrome browser can run on. This includes macOS, Linux, Chrome OS and Microsoft Windows.
Is Checkbot available for Firefox and other browsers?
Right now, Checkbot is only available for Google Chrome.
Why does Checkbot require the Chrome extension permissions it asks for?
To perform crawls, Checkbot has to be able to fetch URLs from potentially any website. The only way to do this in Chrome at this time is if Checkbot asks for the “read and change all your data on the websites you visit” permission. This permission is used by Checkbot for the sole purpose of processing URL responses requested by Checkbot during crawls within the tab Checkbot runs inside. Checkbot does not interfere with your regular browsing in any way. We’d love to be able to ask for less permissions but like with other developer extensions for Chrome, this currently isn’t possible.
Is Checkbot a web service or does it run locally?
Checkbot is not a web service: all crawling and other functionality is performed locally on your own machine. This has the benefit that you can crawl as many sites as you want as often as you want which wouldn’t be practical on a web service shared between many users.
How do I install Checkbot when Chrome keeps saying “this item is already being downloaded and added into Chrome”?
This is a rare Chrome error that impacts extensions in general that prevents installation from succeeding. You should try clearing your browser cache and cookies, restarting your machine and then attempting to install Checkbot again. Please let us know what worked for you as it isn’t clear yet how to reliably fix this.
How do I get the latest release?
Google Chrome should transparently check for and download updates to Checkbot in the background within a few hours of a release being uploaded to the Chrome Web Store. You need to close and restart Checkbot for a recently downloaded update to be applied. If you want to force Chrome to check for and apply an update you can visit the
chrome://extensions/ URL and press the “Update extensions now” button. Be aware that doing this will restart Checkbot and you’ll lose your current progress.
How do I know which version I have?
You can see which version of Checkbot you’re running by launching the extension and reading the version number from the corner of the start page. The version number is also displayed in your list of installed extensions if you visit the
How can I get notified about releases?
We frequently post on Twitter, Facebook and Google+ about new releases so you can follow us on social media to keep up with the latest changes. You can also sign up to our newsletter to keep up with Checkbot news.
How do I report bugs or feature requests?
Should I aim to get a perfect score?
If Checkbot gives your site a low score in any category, we would recommend you address the critical problems and whichever issues you consider important but we wouldn’t recommend you aim to get a perfect score. It’s close to impossible for a moderately complex website to get full marks and even the Checkbot website has to make some concessions. For example, fixing some minor issues might require 1) major overhauls of your backend 2) for you to switch to a hosting solution that supports the customisations you need or 3) a third party script provider to make changes for you. Only you can decide which issues are important and practical to fix for your own website.
How can I export and share reports?
For each report, in the bottom right next to the search bar you should see a blue “export” button. Click that button and the current table will be exported as a CSV file. If you’ve searched for anything, the file contents will be filtered by your search term also.
Can I tell Checkbot to ignore URLs?
In the sidebar on the startup screen, there’s an option to ignore URLs by pattern. See the help text there for tips on how you can give a list of regular expressions to ignore sets of URLs which match particular patterns. For example, you could ignore all URLs ending in “.png”, URLs to “example.com” or URLs containing the path “/login” to stop Checkbot from checking URLs you’re not interested in.
Will Checkbot appear in my site’s analytics reports?
Why does Checkbot report a page issue I cannot see with my browser?
What can I do if Checkbot is being blocked or shown a CAPTCHA?
Some websites have anti-scraping protection in place that block bots or give CAPTCHA challenges. If this behaviour is based on the user agent string, you can try changing the user agent setting used when Checkbot performs crawls. Beyond this, your only option is to get the administrator of the website to add an exemption for Checkbot somehow such as by user agent or IP address.
What does a Checkbot paid plan entitle me to?
If you purchase a single Checkbot subscription, you can use the paid features of Checkbot on as many devices as you wish as long as you continue to make payments for that subscription. If Checkbot is later supported on additional browsers, your subscription will work for those browsers too. You are the only person who may use the subscription you’ve paid for. Each individual requires their own subscription and we reserve the right to cancel a subscription if a subscription is being shared.
What’s the difference between the free and paid version of Checkbot?
See the pricing section for more information about the differences between the free and paid versions of Checkbot.
How do I use my subscription?
When you purchase a subscription, a user account named after the email address you signed up with will be created and you’ll be asked to set a password. To use your subscription, install the Checkbot browser extension then log in with your account using the “Log in” button in the sidebar. You should then have access to the paid features. If you’re having any problems, please contact us with a note of the email address of your account.
What is the refund policy?
We offer refunds up to 7 days after your paid subscription has begun if you’re not satisfied. If you get a refund, you will lose access to the paid features your subscription unlocked. To request a refund, contact us with the email address and “order number” from your purchase receipt that would have been emailed to you.
What happens if I cancel my subscription?
If you cancel your subscription, the features your subscription unlocked will be unavailable to you after the time you’ve paid for already expires. For example, if you purchase a yearly plan and cancel 9 months later, you’ll lose access to the paid features 3 months later. You can cancel your subscription at any time.
How do I cancel my subscription?

How do I get a VAT refund?
