How to not waste blog post traffic?

Hey! A few of my blog posts related to my niche (Webflow) are receiving high amounts of organic traffic. But this traffic is not converting or entering my funnel at a high rate.

Most of my blog posts have sections of content promoting my product, and I updated the design of the blog page to make CTAs to my product more prominent. I also tried retargeting on Facebook / Insta but with no success. My assumption is this is not the best ad channel, as most of my target customers seem to be active on Twitter, Reddit, & Youtube.

So just reaching out to the community to see if anyone has any tips to decrease blog traffic going to waste. Are Twitter or Reddit ads really that bad as ad networks for retargeting 😅?
