If you can edit the html of /cars/ for example add the following between the head tags:


that will disallow robots from indexing /cars/ but should let them index for exaple /cars/whatever/

I hope it helps

socomm im so stupid platinum seo pack does this by default but i just wanted to use it in the robots.txt file instead, but im sticking with platinum seo pack for now thanks.

Are you sure it counts as duplicate content?

so eh..what's the result? or conclusion?

Hello,

A robots.txt file can create a vast impact on your WordPress blogs traffic and search engine rank. This is an SEO optimized WordPress robots.txt file. Remember that if you mess up the robots.txt file by overcrowding too much, you could misplace all of your rank.

Thats a bit tricky as you woud have to stipulate all categories in your robots file:

Disallow
/cat
/cat2

etc.
