I read somewhere on the internet about how to make more money with adsense and the suggetion is:

1: Dont put more then 1 adsense code per page
2: Dont join the 'advertise on this page'

Is it true?

As i can see google suggest this feature on thier website to maximize adsense income.

anyone can give me an advice?

Thank.

It's not really as simple as that. You may make more by following those two rules, But you may make less. It depends on the site.. The best thing to do is try it and see.

Don't read for anything apart from Google's guideline / suggestion on how to make money with your site as all the rest may be telling about the particular type of site and if you site is not of the same thing you tend be doing nothing good to your site. Again Google terms and suggestions works great (go4expert.com) for my site but may not for your site.

Depends on your site. Some websites works better with only 1 unit, while some with maximum of 3. If you are not sure, just test each of them for a week and judge yourself.

Probably we all will say the same thing in our own style <3

Thank guy for your help.

I have tested last few day putting 3 code on top, side and bottom. I found that top code make me more click and pay high. Side code make only few click with average less then $0.05 cent per click and bottom code have make me no money yet.

The first 3 day after i launch the side with top code make me more money then now.

I wanna try to remove the side and bottom code and see what happen next few days.

Thank alot.
