I have a feeling that I've been penalized in Google Search for a while now. But I have no idea how to figure out if I am. I see people posting about having -30 penalties, -15 penalties, etc. but how can they tell?
the -XX penalty is for specific keyword, you have to search the keyword all the time and watch your space, then you can talk
Penalization can cause either of following: Deindex your site or disappear from search results or -XX penalty
what is this -xx penalty? How can you see and measure it please? Do you mean the sites just loses 15, 30 places in rankings etc?
