You don’t have a bounce rate problem…
You have a traffic source problem, mainly that you don’t have any.
Small amounts of data are mostly just random results and cannot be relied upon for making decisions. You should focus on generating traffic until that happens you have nothing to measure and analytics can help you make any decisions.
Connect the Dots
Try writing articles in series, start connecting the dots in your content. For example, I noticed that you wrote an article about “Page Load Speed” and in it, you mentioned using a CDN, which is generally good advice, but why stop there?
Why not write an article about CDNs, comparing options, rating the various services and making a specific recommendation and link to it? Then write and link to a “How to” article that provides step-by-step instructions for setting up and using CDN services on your website. And so on.
Continue on and on with articles written in series that keep users on your website reading article after article, then bookmarking your website for future reference, and linking to it in their own blog. That is how you build an audience and keep them coming back.
