Small Business Owners & Entrepreneurs

I would go back into your Ad Manager, view your Bid and the Suggested Bid. If your max bid is too low they won't serve your ads. The suggested bid can change over time due to higher demand for your target.

My CTR is typically any where from 0.5% to 5% depending on the post being promoted.

My suggestion would be to write a short post "10 Tips Everyone Should Know When Buying Their First Home". Promote it to people who are married between the age of 25 and 35 in your target area. This improved targeting coupled with building curiosity should improve your CTR, reduce the amount you pay per click and get your ad served.
