Try change colors and styles of ads while you receive optimal CTR. 4. Use Adsense tags <!-- google_ad_section_start -->/<!-- google_ad_section_end --> for page content and <!-- google_ad_section_start(weight=ignore) --> for non-content elements. 5. Use Adsense tester and watching for MFA sites and another traffic resell stes. Remove them. 6. ...That is all.. Now I have $0.1-0.15 cliks, and for my keywords that is good.
