When Your Are placing ads You Need To Avoid tricks

When placing ads on your site do not try to trick the reader. By trick I mean any technique that will deceive the reader into thinking that a link or image is not an advertising when it actually is.
Examples of such tactics include making Adsense unit links look like a navigation bar or text link ads that are placed under a “Recommended Links” header. While those techniques might increase your profits on the short run over the long term they will damage your readership base since a deceived visitor will probably be reluctant to return to your site.
If you are providing quality content with non-intrusive and relevant ads there is no need to trick people. Readers will click on advertisings if they find it interesting or useful, and they will do it consciously which is a good thing both for you and for the advertiser.
