my website is http://www.freewaregames.net/ if anyone has any tips to improve my ad placements, please let me know
Okay, I see some rectangle units at the top of the game subpages. Tip #1: I always think these units are very poor use of space. Try using a banner unit instead. Also good if you can weave a few banner units between the other page content (the lists of games). Colours good.
why don't you put the ads in the middle of the site, surrounded by your content! that's the only way to get the best out of your ads! the square units really helps. also get a link unit at the top, that will imporve your click throughs!
i find that the square ads blend in really well. but the gap is kinda big and looks out of place. i am only seeing 2 ads in the square unit, think it shld have been 3? anyway, add more ads in, ad link shouldn't take up much space.
