Thanks very much for all the replies,

I have tried a number affiliate advertising services including adbrite, commission junction etc but i don’t really get any success. I’m not really sure why but the adverts served up by adsense are very close to my website topic. Whereas the adverts served up through other networks seem to be very generic, every day things and not that specific to my site. I think YPN would be a good thing to try but unfortunately I live in the UK so am not eligible for this! I have actually just got my azoogle account activated so am going to give them a try, and see how that works out! Anyone got any recommendations of specific networks that they think I should try?

Regards
Mart
