Content

Everything else being equal, new content will rank higher than older content in search engine results. Of course everything isn't equal. But this is an important factor because you are competing against a lot of other useful and unique web pages out there, so if you can be newer, why not! As a broad strategy this means that you need to create a constant stream of new content on your site. Write a new page every week for your wine website covering a new variety of grape. Write a new blog entry each day if you're a blogger. If you're out of ideas on what to write on, revisit older blog entries and write an updated version on the same subject. 

Pretend you're Google: A friend asks you to recommend a good article on Merlot grapes. You find two of them and they're very similar so you recommend the newer one. Google does the same thing.
