One of the best ways to get highly ranked in Google is simply being first when it comes to the search engine. Google often ranks my posts which are first the best. Many people have figured out this theory and therefore try to post new topics before anyone else does.
Being first in my experience is one of the number 1 factors for getting a good search result. Write it first and you will get highly ranked. Of course having a good page rank can help that as well as many links going back to your page. But in any case, try to be first and you’ll get better ranked pages.
