I looked into this a bit. I think your read ratio is fine and it's not going to be a problem. We changed the read calculation to just be "read for 30 seconds" but we haven't released the new stats page that shows that yet. In that calculation you are getting read ratios above 40%. And it's a bit hard to for me to tell about daily earnings but I don't think daily earnings is a good lens at all. Last month most of your earnings were from two articles and that means the days when you earned the most were when those articles were popular. Neither are getting much traffic in August and you haven't published anything new. A much better test is going to be whatever you publish next (if you aren't too discouraged to do that).
