@MarySue, I just took a look at your page. On the whole, there is hardly any engagement with the Etsy links that you are sharing (I'm not sure what the reach of your links is). This is an indication that you should re-consider your strategy.
Some suggestions:
1. Post images as suggested above.
2. Try not to post more than 3 times a day. 40 posts / week are probably too many.

See examples:

See which posts get the maximum and engagement and try to post similar things. However, try to stay relevant to your business / brand. For instance, you may find that humorous posts get a lot of interaction. So it may be nice to post something funny once in a while, but don't only start posting humorous content since you will move away from your brand image.
