if i have a book store website and have 100000 of dofollow back links from forums,.edu,.gov sites,blogs does this become too much or does search engines really consider in ranking my site up and improve my page rank
I think it highly depends on the age of your domain/site and the frequency in which those links were added. So if you have a brand new book store build just a month ago and you have added 100k of links in 3 weeks then it won't look good
