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.

Review : I’m really happy that I bought this course. Theo was so informative and had really good explanations. I loved how she walked us through setting up our blog step by step which really helped me and also motivated me to get it done. It made starting my blog less overwhelming for me to see her steps on Word Press. She was very thorough and I feel a lot better about it now. She even is responsive on the Facebook group. Would definitely recommend this course! If anything could be changed, I would just want to see even more steps on the word press side as far as physically setting things up. Thanks for a great course Theo! – Jamie Banks
If you have built up an email list, you could also promote your affiliate offers via email promotions. Just make sure you build up a relationship with your audience first instead of going for the hard sell straightaway. The emails you send out must contain your affiliate links to products so when your audience click through. the sale is attributed to you.
Review : I found the course comprehensive and I learned a lot. I wish I found this course when I still owned my Brick and Mortar store, it would have made a big difference in increasing my traffic. I had people coming into my store years after I was open telling me they had no idea my store existed. I used social media but now I see I wasn’t utilizing the platforms to their true potential and that they were not fully optimized at all. I look forward to using what I learned in this course on my next adventure. Makes me excited to get going. Thanks Diego. – Shawn Vesper
When promoting affiliate offers, just make sure you are fully aware of all the terms and conditions attached to your affiliate program. Some programs can be strict about how they allow you to promote their products. For example, some may limit you to banner ads and links only, while others will allow you to use paid advertising, but won't allow email marketing.
