Nice clean design. From my quick glance at your content, it looks pretty decent.
I would change the “join the community” button to something else other than a link that takes them to a Fgroup away from your website.
Maybe change it to link to a mailing list squeeze page, start to build up a list. A mailing list is much more valuable and is something you own 100% that cannot he taken away from you, unlike a FB group.
you can promote your FB page, just do it some where else less prominent. Like in your footer or sidebar.
You are also going to want to add a lot more content. If you want to make any sort of decent money, aim for around 150 articles.
That migh my seem like a lot, but just give yourself monthly or weekly goals and you’ll get there in a 6 months.
I would also recommend you take a look at the project24 program in the education section. They do a good job breaking down some good techniques for writing effective articles as well as finding keywords worth targeting.
I did a test site using there method a few months ago, quickly put up a site and added 65 articles over 1 month. I’m already ranking on page one for a bunch of keywords in a competitive niche.
best of luck
