Posting in news feed every few days or so. Photos look ok but could benefit from a few tweaks. No stories at time of health check. We can work on this. Good use of hashtags. Using a call-to-action and question with most posts which works well.
Aim to post at least once every day in your newsfeed with at least 3 or 4 stories per day. By ramping up your frequency of posts you will gain more attention.
Keep using hashtags and call-to-actions in your posts.
Your photos could do with some tweaking. The shots which have the amps positioned higher than the camera with the camera looking up look great. Eg. The post on Feb 25th.
Try to do more posts like this and keep the photos looking professional.
