Pros : More number of advertisers and comparatively good targeting .
Widgets and auto installers for all major blogging platforms and CMSs.
Cons :Kontera really sucks when it comes to the payments . They offer support for the user to generate higher revenues but its not that working .
Payments only after 100 $ ( Via Paypal or Check ).
Statics page is not so impressive .
Pros:Higher payments: About 2-3 time more payment than Kontera for same user traffic(US) .
Other in text advertising networks can be used along with infolinks
Cons:They currently support only very few countries and in unsupported countries , visitors are shown with a dictionary ad which not even worth a cent .
Payments only after 100$ ( Via Paypal or check )
Tooltip needs flash player .
No plugins and widgets ( Infolinks tag should be placed manually )
Less secure user login ( No SSL security )
Kontera : If you are a publisher outside US and not getting good US traffic .
Infolinks : Inside US / outside US with good US traffic .
In text advertising programs offered by Adbrite and Clicksor are not so popular as Kontera and Infolinks . They need plenty of traffic for generating a neat sum ( In most cases its not that neat !!) .
