u can use keyword tracker. people said it's effective. for me i never use it. i get only 50 unique everyday and 5 click or less. but my earning is good. maybe just my luck that i use high paying keyword
Sandy23, The ads are served based on your site's content. If you want better paying AdSense ads, you need to target content that advertisers are willing to pay more for. Stay away from game sites and MySpace stuff. You might attract a lot of visiotrs, but the per click payout is tiny. Try targeting a hot real estate market or another very competitive niche where there are lots of advertisers trying to get into the top of the results. They will pay much better and you need considerably less traffic to make decent revenue. Cheers
there are some threads give you suggestion about high payment keywords here in DP. search a bit and you will get what you want. good luck.
