Quality and Sticky Content

Good site content builds credibility and lends to a higher CTR
rate. Keep your visitors interested so they return. You want
them to add your URL to their favorites and come back
often. Those returning visitors will lend to a higher CTR and
increased revenue. Keep the quality content fresh too, so
they always have something new to read.

Sticky content on your site and keywords related to that
content. Find the higher rated keywords and key phrases
for what your site offers and create sticky content around
those. You can include breaking articles in relation to your
product or service, testimonials, discussion groups, or
surveys and polls.

Give Away Free Content
If you have articles on your site, as you should, and write
them yourself, consider allowing your visitors to use those
same articles on their sites or in their e-zines. In exchange,
you just ask for a link back to your site when they publish
the article.
