Have you actually used the extension ? The 3 stars seem a little unfair :(
SocialAds is a full Advertisement management system for Joomla offering the most advanced Advertisement platform in the market as of now. With extensible targetting including Geo, Social & custom as well Zones & Ads in Emails.
If no one buys Ad Space, we have the option to let you display Affiliate & Google Ads to use the space till you get your own Ads. There is no other free extension available that gives you all this..
my main problem is why not supported new version of Joomla... very important to be available to all.
I give 3 stars and thanks to the developer.
please make available for all Joomla version!
