How can you tell if a visitor to your site is real, or if it's a bot?

Sometimes it's difficult, if not impossible, because they're so good at disguising themselves.

But bots are robots... they're automated scripts. And because of this we can use their own limited behaviour to spot them.


Shield Security Pro 7.3+ has a Mouse Trap feature for detecting bad bots. This feature is one of a few other bot detection signals which we discuss in more detail here.


The Mouse Trap works by leaving a bit of “cheese” in the form a link that alerts Shield to a bad bot whenever it’s been accessed.

How to capture bad bots?

To capture bad bots is a simple matter of switching on the option and Shield will take care of the rest. When enabled Shield Security will:

  • automatically update your robots.txt file to indicate the virtual links that are not to be indexed.
  • automatically include an invisible, fake link at the footer of all pages on your site. This is the cheese to tempt the bad bots.

Options for handling bots that nibble on the link cheese

There are 4 options for dealing with any bots that access the fake link in the Mouse Trap:

  1. Log the event in the Audit Trail
  2. Increment the transgression counter for that IP
  3. Double transgression counter for that IP
  4. Immediately block the IP address

Note: How your site responds is entirely up to you. To err on the side of caution we recommend option #1. But if your patience is a little thin for bad bots, choose the option #2 and immediately block them from further probing.

We definitely advocate a more lenient approach in the beginning. Test this feature on your site by assigning black marks against and IP address several times before outright blocking it. In this way you can be sure the feature works well for your site before firming up your protection and instantly blocking offenders.
