If you want the search engines to find your blog, hub or website and rank your pages, then you need to post on a daily basis. Some writers that I know put aside one day and write all their posts for the week and submit on a daily basis.

Page rank will increase if you link between different posts and pages on your website. One of the best ways of raising your Google page rank is to post comments on blogs and websites that have a higher ranking than you and leave your URL next to your name. If they follow the link you will get an inbound link from a site with a higher page ranking than yours; this can boost your page ranking.

Don't be too impatient this demands a fair bit of work and Google often doesn't list page rankings for a month or longer - so it could take a while to see a change in your page ranking.
