For SEO specialists and my old Black Hat crew. An SEO high wind advisory. I admire the creator of this link scam for their ingenuity. Xrumer is an autosubmitter program - it will sign you with up with major forum software platforms like phpbb and even post your first post for you. Not much new with this type of software, but their game plan is brilliant. They are using their own software in a massive one way link blitz. This dwarfs the old Google bomb by a longshot. Their first auto-submitted post does not contain a link, it simply says something along the lines of: “I am looking for Xrumer auto-submit software, does anyone know where I can find the official website?†- Because they did not drop a link like most spammers, it goes unnoticed as spam. Now enter the well meaning member (and I have seen many ADMINS fall for this) who googles Xrumer and posts the link for them. They have just received a bonafied link from a trusted member of that community. Now that is quality spam! You can google Xrumer yourself to see how many forums are hit with it - it is quite impressive. It has hit so many forums recently that I really do not think there is a way to undo it - They got massive linkage. Do not be tempted to buy it, Google will figure it out eventually and penalize it. Maybe you could get away with it if you had a mark that was already branded for linkage - take your chances. A couple things to consider if you are tempted in buying the Xrumer software: 1) The obvious - you are perpetuating Black Hat SEO and spam. 2) Xrumer is a very unique search term, the same ploy would not work on any competitive term - and if you already have branding for your term, you would not want to take a chance with this anyway. 3) If you drop a link on the first post with the program you will be tagged for spam. To drop a link on the first post is the intended use of the software. Xrumer got around this with a unique term and disposable domain for quick cash.
