Hiya, i run 2 websites which generate between 1200 & 2000 unique visitors a day per site, these websites both have Google Adsense plastered all over them. Until about 5-6 months ago the sites together would generate 20-30 dollars a day but for some reason the sites are now bringing in around 10-15 if im lucky even though the traffic to the site is still remaining the same.

My questions are does anyone have any advice or tips on how to get the max out of Google Adsense ? is Adsense paying less or being blocked by some computers, explorers etc? and is there anything else out there that is likley to bring me in more money from the sites ?

The car websites are are based around car tuning, modified cars and car show girls. So the advertising on it would probably be best if it had something simlar advertised to interest the visitors i guess.

the websites are

http://www.maxtuning.co.uk and http://www.carshowgirls.net

any advice would be greatley appreciated

thanks
