Your display ads should be visually stimulating to viewers and aim to hold their attention long enough to entice them to click to your website. Though it's natural to want to share all the details about your product, you should be as simple as possible with your display ads so that viewers aren't overwhelmed. If you include too much information right off the bat, viewers could stop reading or lose interest - simply because there's too much to read. The ad should be simple and direct.
Another one of the highest paying and most popular dating affiliate programs is eHarmony, which is based on the actual earnings that can be made from each referred sale.

Focus on reviewing products that fall within your niche. Then, leveraging the rapport you have created with your audience and your stance as an expert, tell your readers why they would benefit from purchasing the product you are promoting. It is especially effective to compare this product to others in the same category. Most importantly, make sure you are generating detailed, articulate content to improve conversions.
