If you have an e-book or online course that you'd like to promote, ClickBank makes that easy. Once you sign up as a vendor you can list your product with them and set the commission percentage you are willing to pay to anyone who chooses to market and promote your product for you. Once your product is listed, other ClickBank users will start promoting it on their own websites. This will drive traffic to the sales page on your website and hopefully result in sales.
Drop shipping is another great ‘hands-off’ way to sell products. Firstly you will need to find businesses that sell products in your niche that offer a drop shipping service. Then you will need to create a website promoting and selling the products. When you make a sale, you take the payment on your site and then the manufacturer ships the goods to the buyer. The profit comes from charging a higher rate than the manufacturer, and if you are selling a high number of products this can quickly add up to a healthy revenue.
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.
