Too general a question unless you define your niche. Also if this is Adsense earning then you are violating the TOS
I do believe your earning is good. But you should tell us what is your niche so that we can give you more assistance.
There is no violation here. You can post earnings, but not CTR. "Confidentiality. You agree not to disclose Google Confidential Information without Google's prior written consent. "Google Confidential Information" includes without limitation: (a) all Google software, technology, programming, specifications, materials, guidelines and documentation relating to the Program; (b) click-through rates or other statistics relating to Property performance in the Program provided to You by Google; and (c) any other information designated in writing by Google as "Confidential" or an equivalent designation. However, You may accurately disclose the amount of Google’s gross payments to You pursuant to the Program. Google Confidential Information does not include information that has become publicly known through no breach by You or Google, or information that has been (i) independently developed without access to Google Confidential Information, as evidenced in writing; (ii) rightfully received by You from a third party; or (iii) required to be disclosed by law or by a governmental authority. "
Apparently you missed the part that was bolded: "You may accurately disclose the amount of Google’s gross payments to You pursuant to the Program" Since payments are made from earnings and you can discuss payments, that indicates you can discuss earnings.
If you got high CTR, above 30% in regular daily i think you will got 'yellow or even 'red' flag for your account standing. Where your visitor come from, rich of unique content and much more are some important point of your adsense.
$9 For 90 clicks is quite low, If its the link you have in your sig then yeah its bad for 90 clicks ill be on around $90, my niche is dating. What countries is your traffic coming from.

I got $44.67 for 22 clicks, ... i don't place too many ads on 1 single page. I use google search block top and bottom, 1 large mid block and a small 468x60 text-image on all. Name your ads and follow they daily clicks, I pick a day to check my stats and move my ads around. Use multiples color only on title not back ground. Name your titles with channel and follow up in 2 days see how they perform. my lucky color is lime green, this one has perform well for me. But everyone is different. Good luck.
