While your site is still new, it's a good idea to start capitalizing on someone else's audience. Continue focusing on building your own content, but also considering writing content for a few big, high-traffic blogs that are relevant for your niche. By writing content for a bigger site, you are able to get in front of another audience and showcase your expertise on a particular topic. This will eventually lead to more traffic to your site, as well.
I, too, have always looked at ClickBank as a secondary and even tertiary monetization source. But it can be a great sources of revenue. I linked one of my articles to a related product on CB, and without really doing promotion or anything unusual, I get a few sales a week. Mind you, the keyword(s) for the post aren't that huge either. So, even though the traffic not huge on that post, it still manages to get some sales.
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.
