So how do you go about this? What (free) tool do you recommend?
Also, how do you handle the accounts? Do you set up separate accounts on each bookmarking site for each niche? Or do you just get one account at each and use it to bookmark for all your niches since nobody should suspect they are linked in any way anyways?
Also, do you just bookmark your Tier 1 sites or do you also throw in some random bookmarks to other unrelated sites just to make the bookmarking look natural? Or does this not matter as nobody checks anyway and just a waste of time?
Really appreciate some guidance on this.
