vBulletin Manual - Identifying Spiders on Who's Online

If you have set the "Enable Spider Display" to yes, the file includes/xml/spiders_vbulletin.xml is used to determine how a spider is identified.

The file looks similar to this:

<?xml version="1.0" encoding="ISO-8859-1"?>

<searchspiders>
    <spider ident="https://www.almaden.ibm.com/cs/crawler">
        <name>Almaden Crawler</name>
        <info>https://www.almaden.ibm.com/cs/crawler/</info>
        <email>[email protected]</email>
    </spider>
    <spider ident="Ask Jeeves">
        <name>AskJeeves</name>
    </spider>
    <spider ident="Googlebot">
        <name>Google</name>
    </spider>
    <spider ident="Mediapartners-Google">
        <name>Google AdSense</name>
        <info>https://www.google.com/adsense/faq</info>
        <email>[email protected]</email>
    </spider>
    Place additional spiders here!
</searchspiders>

If you want to add spiders to the list, you should add them in place of the red text (just before "</searchspiders>").

At the minimum, you should provide the ident attribute and the name tag. Other tags are simply for your information and not used. The ident attribute is used to distinguish a regular guest from a spider. The value of this attribute is looked up in the browsing user's user agent (what the user's browser identifies him/her as). If a match is found, the value of the name tag is displayed on Who's Online.
