Very good: shows all bot-crawlers.
Our website was sometimes down due to bot-crawlers, with this tool it is easy to solve. Very good logging of bots.
This was the only good plugin I could find for this purpose.
Some bots ignore robots.txt. So I manually changed htaccess, that worked very good.
Easy to understand and set up.
Keep on keepin’ on …
Bingbot and googlebot are hitting my site with hundreds of visits per minute and Gavin from support spotted the problem immediately!
An easy improvement would be to link to the settings page from the plugin entry like other plugins, other than that, in general this plugin and its online dashboard is generally well thought out and useful. My website is small and has limited resources that get overrun by crawlers making it unavailable. This plugin helps identify the culprits and decide if I should block them or not.
For free you can block them in robots.txt, as I have a physical file, the plugin won’t touch that but its easy to add manually. It will report those crawlers that ignore the robots file and the paid version will enforce those rules, but I just update “.htaccess” myself.
I’m reducing my rating by a star since you won’t get much “Agent Analytics” (per month) and for my tiny site it quickly ran out, we are a NFP so don’t have money to burn on subscriptions. The the description for the plan incorrectly states “Unlimited Agent Analytics” when the plan only includes 100,000 events.
Please remind me in a month to provide an update on the performance of this plugin on a heavily visited website.
