Because of my low English knowledge, im edit my blog post one or two times. Each time i edit blog post, wordpress send ping to SE. It is reason for Google penalty... How to avoid it..
Simple answer is NO, Google penalty are applied mostly when you have bad neighborhood links or duplicate contents
My blog not get google penalty, my google traffic reduced 1000 per day to 50.... I am not find any reason....
Did you already check your SERP rankings? Urls? backlinks? content? Layout? Over pinging doesn't have relation to Google penalty.
I create 2 to 3 article and post it within 15 minutes.... Posting 2 or 3 article same time create any problem?
It won't give you a penalty as I'm sure it's a big problem on all the blogs. I'm always editing/updating my blog posts and I haven't been penalized...yet
You won't get penalty from google when you ping more than necessary but ping servers may ban your ip.
If you ping to SE again & again they will not ban you but ignore your requests because they consider to you spam or anonymous user.
