Existing ad mods in SMF are either complicated to install or outdated.
Need a MOD for inserting adcodes from adsense or other networks or our own link/image ads.
They should be added in between posts, on header, footer etc.
Now that google adsense has lifted the upper limit on number of ads per page (earlier was 3 ads per page), we can have 3-4 ads in each topic/page if we've enough content and monetize forums.
Also, these ads should be in kept in rotation.. like auto change ads in a particular position after few days/weeks etc.

Thanks a lot for your suggestion! This one has being indeed in my mind for sometime, and it's possible that an implementation is actually done at some point!

Defo think you should do a ad management mod. 
Got your theme and SEO mod. I just need ad management from you now

Another vote for advertisement! Seems like something that needs to be added!
