Fresh Content

Content which is dynamic in nature and gives people a reason to keep paying attention to your website, or content which was recently published.
Many SEOs talk up fresh content, but fresh content does not generally mean re-editing old content. It more often refers to creating new content. The primary advantages to fresh content are:

1. Maintain and grow mindshare: If you keep giving people a reason to pay attention to you more and more people will pay attention to you, and link to your site.
2. Faster idea spreading: If many people pay attention to your site, when you come out with good ideas they will spread quickly.
3. Growing archives: If you are a content producer then owning more content means you have more chances to rank. If you keep building additional fresh content eventually that gives you a large catalog of relevant content.
4. Frequent crawling: Frequently updated websites are more likely to be crawled frequently.
5. QDF: Google's query deserves freshness algorithm may boost the rankings of recently published documents for search queries where they believe users are looking for recent information.
6. The big risk of creating lots of "fresh" content for the sake of it is that many low cost content sources will have poor engagement metrics, which in turn will lead to a risk of the site being penalized by Panda. A good litmus test on this front is: if you didn't own your website would you still regularly visit it & read the new content published to it.
