Based on all the information we have gathered during our in-depth research we assign a magic score to each vendor. This is based on factors that affect any solo ad purchase (for e.g: CPC, Sales, Conversion rate etc). We use our proprietary algorithm to do this. As a rule of thumb, higher the Magic Score, better the solo ad experience is going to be.
Building subscriber lists is a common need for email marketers. The important thing to remember with this objective is that your email marketing should be focused on quality and not quantity.
