Link-building is all about establishing credibility on the Web. Think for a moment: if my business and website were top of mind and authoritative, where would I expect it to be listed or referenced on the Internet? Where are my competitors referenced?

Links pointing to your website are considered quality links if they are on sites that are relevant for your topic or to your audience. Increasing the incoming links to your site from quality sites will go a long way to establishing Internet credibility.

There are many strategies to conduct a link building campaign, but we recommend these:

• Registering the site with appropriate online directories
• Establishing link exchange relationships with other quality and on-topic websites
• Publishing press releases and articles online (on relevant news sites)
• Developing a link worthy resource or tool that becomes "viral" on the Web
• Some social media sites are useful for link building; others are not.

Link-building is, by far, the most difficult part of a complete SEO plan; those who sacrifice quality or are impatient will not be rewarded for their efforts.
