Some of methods by which you can increase you backword link counts
1) Directory listing
Get your site listed in the Open Directory Project (Dmoz) which is
free Google uses this site to assist its indexing, it is used by
many 100s of other search engines. Get a listing in the Yahoo
directory as this the leading directory. There are many regional and
lesser-known directories that are also worth considering.
2) Request links
Start by visiting the open directory, and search using your keywords
you will find the sites listed here are normally already well ranked.
Select sites you feel will be open to a link request. Put a link on
your site first then ask for a reciprocal link. Try also using Alexa
to identify highly ranked sites then use their show links to feature
to identify their backlinks (sites linking in) then approach these
too.
3) Promote inter-site linkability
Internal links as well as external links contribute towards Page Rank
a site with a good link structure is also more likely to appeal to
potential link candidates than a site with a poor structure.
4) Publish articles
Consider paying professional authors to write articles on your behalf
then submit them for publishing on the condition that a link to your
site is attached. This can be a very successful strategy but time and
effort is needed for it to pay off.
