And which ones are those ?? A link is a link and can't have negative effect otherwise people would be linking with bad links to their competitors
How can we know which directories Google does not trust? Because if I am submitting my site manually to any directory then I van submit it to a wrong directory because I was unaware that this is a black listed directory also tell me does google punish those sites which are listed in such directories.
I don't think that's true.. otherwise I would try HARD to locate such directories and submit my competitor's websites there.
I have used both digixmas and reseller go... both the tools are good but as a lot of people are submitting using those tools so the directories (those are there in the their list) are flooded with pending links and they are not approving. get the list of directories from digital point or google and submit one by one. you will get better results. I have tried all 3 methods ( digixmas,reseller go and total manual submission one by one) and i found that when you submit manually, there is more probability that your site will get fast approvals as there are less no. of submission for these directories as compared to directories which are there in tools. Thanks...
