Hello, I have been a member here for quite some time now and am quite familiar with White Hat/Black Hat SEO and Link Building process. I am looking for a good and reliable link builder, or link building solution to rank my hundreds of websites which are spread across different niches. I have about 10 Master Sites, and 500+ Direct Response Sites which connect into the different master sites for final checkout. Some of the keywords/search terms are competitive, while 80-85% of them aren't too difficult. The sites are on different servers so they're not all sharing the same IP, and sites which are on the same server are not inter-linking between each other. All sites are custom developed and on-page SEO is done. I have full flexibility to do any type of tweaks needed in the platform or source code of the individual sites / database which would help the ranking. I've been working with a few link builders till now but one was very unreliable, and the other is available only half the times. I haven't played around too much with SENuke or Xrumer as I've been busy putting all these sites together and building the content for each, but now that I'm ready to execute, I'm looking to work with someone who has a good track record and is knowledgeable in this field. Thanks, and any/all help or suggestions would be much appreciated.
