I've checked the forum. Ad Sharing Plugin seems to work best with:
2. In Post content (not sidebar)
Q1: How can I add other affiliate programs like Amazon and CPA like NeverBlue? The Ads should display based on the post categories or niche tags.
Q2: Is Ad Sharing integrated with MarketPress's external link setting?
For example, I create a new product and choose an Amazon product and put the external link there. Can AdSharing work?
Q3: AdSharing sidebar not available?
