Please note that you might get an "Apps, extensions and user scripts cannot be added from this website." message or similar to this:

Please IGNORE the message - this is Chrome’s default message to protect users against downloading nasty applications. Of course, our SEO Toolbar isn't one of them ;)


If you've completed the above steps but still can't install the toolbar, please contact Ahrefs support for help.
