Here’s a tip unrelated to your question, but important nonetheless….
It’s very helpful to create a headline that describes your situation, rather than something like “i tried this….” which doesn’t tell anyone anything about the post. Chances are that few people will click on a post with a nebulous subject line. This one could have said “Does repeat posting work?” or “Should I repeat my FB posts?” or something along those lines. I bet you’d get a lot more involvement.
Of course, that doesn’t explain why I clicked on it, except that I’m anal. And BTW, I don’t repeat my posts. I think it’s not a bad idea, but the organization for which I post, I think it’s not helpful.
