Google ranks websites through its relevance via Pagerank.
Knowing your Pagerank is important because it helps you keep track of your search engine optimization efforts as well as it helps you rank higher in the google index.
LINKS
Pagerank measures how many websites link to your site. More important than the quantity of the websites is the QUALITY of the websites that link to you. This means, the higher their pagerank is, the better your rank is.
You can submit to a lot of directories such as the search engines (google, yahoo, msn, aol, etc) and directories (dmoz.org) but don’t forget about portals specific to your website (ie, if you have a wedding photography website, submit to wedplan.net, wedj.com, etc.) as well as regional websites (specific to your country, state and city). Some website will call you on the phone trying to sell you higher placement, but in my experience, it really is not necessary. Just tell them, no thank you and just hang up. But expect a LOT of phone calls especially from the wedding industry.
Also, links to your website without a reciprocal link from your website to theirs are measured higher than if you link back as well.
A great way to increase your inbound links without having to reciprocate is by participating in message boards, classified ads and forums. Some forums allow you to create a footer so you can include your website in all your posts. Trying to mess with the pagerank by spamming and other similar ways is frowned upon and your website might get penalized because of this, so make sure that what you post is relevant to the topic.
CONTENT
PageRank is also judged by how relevant your website is with regards to specific keywords.
Make sure that you have a lot of text in your website. If you have a flash website, make sure you have a HTML site that is text-rich with your important keywords.
Create articles and tips that you can place in your website. It does not have to be complicated, just a simple guide for beginners will usually do.
BLOG
Funnily enough, the single thing I did that increased my google pagerank 2-3 points higher is getting a blog. Not just getting an ordinary blog, but getting a blog here at wordpress that is hosted on THEIR server. I’ve had blogs on blogger and blog.com before but they didn’t really affect my rank. I switched to wordpress because they allow bigger photos. Less than a week after I created my wordpress blog, my pagerank jumped for my 2 websites. I don’t have any proof that it’s due to wordpress, but I’ve been submitting my websites everywhere and only when I got a blog did it jump higher.
