My site has dropped today in google. I havent changed anything lately except I got 150 free directory links in directories with PR 3- PR8 . Could that have affected my serps? If so how do I get back up in google?
"I got 150 free directory links in directories with PR 3- PR8 . Could that have affected my serps?" If doing directory submission make a site drop in search results then people will start to do it for their competitors in order to get their competitor's site drop in search results. Google ranking change all the time. To get a stable position, build backlinks.
