Is it possible to block all search engine robots?

[Jesse_Smith]

I'll be doing PPC stuff, and I don't want those pages geting listed in the search engines. Is it possible to block all search engine robots with .htaccess?

[marcs]

Use a robots.txt file to block all robots:

User-agent: *
Disallow: /

[marcs]

To quick on the 'Submit' button :)

Replace

Disallow: /

with a Disallow entry for each of those page unless you do want to declare the entire site off limits to robots.

robots.txt will only block "good" robots, those which obey robots.txt, but not the malicious or badly-coded 'bots.

A user-agent blocking rule and a spider trap script can take care of the bad ones; try this A Close to perfect .htaccess ban list [webmasterworld.com] post and this modified "bad-bot" script [webmasterworld.com] post for more info on how to take care of them.

HTH,
