I didn't find a post comparing these 2 types of links(I might be wrong), so I thought I'd write a little bit about these 2 most popular linking methods. Everyone knows you can do mass commenting through scrapebox, or mass forum profile generation through xrumer. Some people like me are asking themselves - whats the difference between these two? Are they just another link, I mean what big of a difference can there be? Actually - quite a bit. Let's start with comments. Pro: SB is cheap if you want to do comment spamming Possible to comment on high pr sites Commenting is as easy as filling in name, website, comment, if you do it manually Mass link building on autoapprove blogs with your desired anchor text with generic comments. Con: Everyone can comment on the same page. Sure, some pages make it harder through moderation, but you get my point - this means more OBL, and the more OBL, the less link juice for each one. Links are at the end of the page, meaning less link value. Manual high PR commenting means you probably need related comments, and can not use your desired anchor text as name due to Moderation. Direct mass comment backlinks to your main URL will get that Domain banned, making it impossible to direct link once you decide to do manual high PR commenting - at least on blogs with akismet. Profile Backlinks: Pro: Your Profile Page is yours alone. No one can add his links, meaning low OBL, high link juice. You can add several Links to the same page. Less moderation (I think). Your links are NOT in the footer area. Con: Takes more time when done manual. There are no high PR profile pages, unless you do heavy backlinking. The domain PR might give some juice on it's own, but thats true for comments as well, and they can also have high pr pages on a high pr domain. Xrumer is expensive as hell in comparison. Of course it's better to mix them to avoid footprints, but it's good to know the strengths and weaknesses, isn't it? If you know any more pro's or con's, feel free to post them here.
