Like others have said it really depends on the quality of the links. You would be better off spending that time looking for a couple of good quality links, rather than just dropping your link anywhere you can as quickly as possible.
If it is from forum posting, I can easily hit 20. If it's from blog commenting maybe about 10, because of the time taken to search for dofollow blogs.
Depending on what tools I was using, I'd say maybe 1,600 links or more if I was concerned with just pushing out link volume. That's just focusing on quantity though.
Hi, I'm new here, so forgive me if I'm not buying this 'mine is bigger than yours' discussion. Yes, links can be build very fast, but are they useful for SEO? Will your link stay after one week, one month, one year? So, lets rephrase the question: How many links you can get accepted by Google in a day? (if this is possible)
I build about 20-25 quality links in that time period and enough for a site to rank well with a one week work
Don't you think that you have to research who you want to link to, and who has a good page rank. then you have to fill out all the info. To say you can get so many it is hard to believe.I can sit for a good while and be lucky to get 3-4 good ones.I would say that was a good day.
