Hello All... Is there any software or something which can tell me how can i check penguin updates (Penelity)...
I am not aware of any software. However, if you use a rank tracking tool that saves your ranking overtime like Rankerizer does for example (I am not affiliated), you can see whether an update has had a negative impact on your site. If a person sees loss of rankings that last for about a month or more after the update, I think that a conclusion can be that in fact he/she has been somewhat penalized.
The only reliable place for this is Google Webmaster, and we don't have it on Google Webmaster till now.
