Linkpushing is a process whereby you build an infrastructure to bring your site
to the top of the search engines without leaving the footprint that a contrived
process like a linkwheel would leave.
Totally White Hat - Great for New or Seasoned Sites!
In that it is a random chaotic process, there is not opportunity to even generate a footprint
and in that a linkpush uses different web 2.0 properties, article directories, Doc Share sites,
Micro Blogs and social bookmarking sites it will never be a method that will be hurt your
site in the search engines as linkwheels have.
The process has been tried and tested on a variety of sites by some very good SEO people
and each and every time it has given the targeted site a boost in the search engines for
many different tough to rank for keywords.
