Content - This is the most essential to traffic flow. You have to offer something that makes your site worth visiting. Content creates repeat visitors, increases their stay, encourages word-of-mouth type promotion and assists in improving a blog’s standing with the search engines.
Links - Every link can conceivably serve a traffic producer. If someone finds a link to your blog on another site, they are only one mouse-click away from being part of your traffic. Search engines also assess the number and quality of links to your blog. They regard sites that are linked to frequently as authoritative and reward them with higher placement in search engine results.
