The biggest problems are those you can see in the thumbnail — or rather, that you can’t see: The entire cover is unreadable and unintelligible. The fonts are too neutral and unassuming, the orange-vs-teal color scheme doesn’t contrast in value enough for the subtitle to be distinct from the background, and the stock graphic doesn’t seem to have any relation to the topic — it certainly doesn’t draw in potential readers who would want to learn about online businesses. The entire effect is definitely not a passionate one.

My advice would be to start again from the concept up.
(And as an aside, I have no idea what a “PMP” is, or why that designation improves your credibility.)
