An e-commerce merchant that wants to be able to reach a wider base of internet users and shoppers may hire an affiliate. An affiliate could be the owner of multiple websites or email marketing lists; therefore, the more websites or email lists that an affiliate has, the wider his network. The affiliate that has been hired would then communicate and promote the products offered on the ecommerce platform to his network. The affiliate does this by implementing banner ads, text ads and/or links on their multiple owned websites or via email to their clientele. Advertisement could be in the form of articles, videos, images, etc., which are used to draw an audience’s attention to a service or product.
If you have pop-ups and optins on every page, I would have to think that it would be a lot harder to convince someone to link to it. Especially since the pages where you have your optins (and probably receive the most traffic) are probably the same pages that you have your best content on as well that you'd be hoping to pitch in your outreach campaign.
