I notice your ad units in the center of the page, just down a little. They do not say that they are adsense ads or anything. Did you edit the code? Because thats a ban, you must leave it intact.
thats pretty good I have one site that makes about $100 a month and it pretty much supports registration etc for all of my other domains
No it is not Against adsense rules but always remember that don't place them near images . Their are so many premium adsense users those placed ads inside posts and Their ctr is very good too .
Its pretty good... keep working on your site and adding rich content so that your earnings dont decrease... if you sit back and relax ...you can see the earnings drop down even if you have the same kind of traffic
It's good payment for you and for me too if I had this one. I think you are getting nice payment for your niche.
I suggest you work on getting more traffic. Traffic = $$$ What you have earned in a month looks good. You are getting good money per click. I usually get $0.03 per click.
