Add-On Type(s)



Lightweight PHP plugin for EE2 that detects a search engine crawlers using PHP. Useful for when using modals on pages and you want search engines to index a different URL for these links instead.

This is my first time writing any any sort of plugin for EE. I’m not a very strong PHP guy so go easy on me :-) Please post any suggestions, changes, bugs, requests, etc to GitHub issues.


Download and unzip the archive. Create a folder called detect_spider, place the file pi.detect_spider.php inside the folder and upload the detect_spider folder to /system/expressionengine/third_party/.

Basic Usage

Check if any crawlers

{exp:detect_spider} - returns true or false

Conditional check for a crawler

{if ‘{exp:detect_spider}’}
  I am a search crawler
  I am a normal visitor
