Trade links with other sites.

You don’t have to spend a cent. All you have to do is reach an agreement
with another webmaster. With exchanging links, the efforts both sites do
will benefit both sites. Every traffic that goes to the site could potentially
click on the link of your site and visit your site as well.
A major prerequisite in exchanging links with other sites is having the
same niche or content as the other site. They should share a common
subject so that there is continuity in the providing of service and
information to what interests your target traffic.
Exchanging links also boosts your chances of getting a high ranking in
search engine results. It is common knowledge that search engines ranks
high sites that have inbound and outbound theme-related links. With a
good ranking position in the search engines, you will generate more traffic
in your website without the high costs.
