I post a lot of different things. I get the most views from photos, though, so I post and repost those in different contexts often. For example, I post a photo with a link in the caption when I first list the item, and repost it when I renew the item, then repost it again in another album if it applies to the latest holiday. For example, I have an album of Mother's Day gift ideas with photos of and links to my products that would be good for Mother's Day, most of which are also posted in other albums on my page.
I also post questions, but don't usually get any response to them. Just trying to engage my fans but for some reason I just don't get any response.
I post events, sales, coupons, links to other shops I admire, a little blurb when I'm producing a new product line, tips for upcoming holidays, that sort of stuff. You can check it out, links are all over my shop.
