Mh… very hard to answer, as paid advertising is very dependent on accurate targeting, paired with appealing ad assets.
I know that you have very good graphic design content, and your model images are very well selected.
Overall your shop and social channels look great. So this part of your homework is done.
One thing that surprised me instantly is the engagement rate on your FB site.
Though you have reached >4k followers there´s nearly no interaction with your posts.
This can be caused because of bad quality of recruited followers or by FB´s relevancy algorythm “Edgerank”. (I would need another thread to explain it´s parameters) This algorythm scores your content based up on 3 major properties.
And I also would need to have more insights into your community’s health, by looking at specific stats.
To me it looks like you are not achieving the full potential reach anymore: Means: you are not visible in your fans timeline any longer.
In general I´d suggest these things:
- spend 3-5€ on daily FB group ads, to attract fresh new fans
- post more biker relevant content that your audience can relate to (fun pictures, facts, interesting stuff - do not post only external links! FB does not weight that as valuable)
- do this daily 1-5 times (yes, it´s a lot of work)
*reduce the ammount of posts that only have the goal of selling your products drastically.
Only post them when promotions are running.
*include your audience into your page activities
This will take a lot of time, but after 1-2 months your audience as well as your reach will be back up and make it much more easier to attract people.
