Mike Liebner's popular Article Underground service has once again opened it's doors. With some limited slots available in phase 3.
Mike provides a large number of keyword rich articles each month, with a strong focus on search engine optimization.
The stand out benefit with Article Underground compared to other PLR services, has to be the announcement blogs.
You get access to a growing network of blogs. You can add keyword rich links back to your home page, and every individual article page on your sites.
Because these blogs are very active with lots of posts, the search engines visit daily and will quickly find and index your new sites, via the links you add to your posts. (some are page rank 4 and 5 blogs).
