as PPC is quite popular in various parts of the word, maybe if you share which country/continent you are aiming at, that way the correct engines will be pointed out.
(from a place called England)
My Personal Top 10 ;)
Note: Most Englishmen seem to like ESpotting.com.
vibgyor79, thanks for that :)
If anyone else would also like to mention their favourites too, that'd be great.
1) Google Adwords
3) Espotting (Europe)
6) Search 123*
*No longer using these ones.
Still trying to find #5 that will sell STUFF
Google Ad Words (but expensive)
Overture (wide reach, expensive too, but less than AdWords)
FindWhat(less reach, but cheap, and good conversion)
Sprinks (can't say much about them yet, but not cheap)
Re my last input as regards Find What: I should have said, good convesion if you trust the FindWhat recent ad analyzer tool which reports conversion. I don't use any other means, and am not so sure it works as advertised, but if it does, then good conversion.
1) Overture (only because of volume of traffic)
2) Google Adwords
I gave up on all the others, but should revisit them now that they have grown.
Never fall for the browser keyword plugin companies (they give you exclusive permission to a keyword typed in the address box of IE, but in reality a user must download their plug in to make that happen).
I like brainfox at .001 it is virtually free
