SEO Google Tips

PageRank explained

PageRank is a link analysis algorithm which gives a weighting to a website / webpage. Its a number representing how important a site is from how much support it receives, in the form of hyperlinks. A page that is linked to by many pages with high PageRank receives a high rank itself. If there are no links to a web page there is no support for that page.

Displayed numbers are scaled logarithmically, meaning a PageRank of 4 is rated 10 times larger than PageRank(PR) of 3. Google.com has PR10, google.co.uk has PR8, a newly indexed site with no links to it has PR0 but this may not display if it has not been live since a PageRank update.

PageRank is a trademark of Google but other search engines and similar patents exist for calculating a page’s importance. The higher PageRank the better.

Search engines result page’s or SERP’s will be updated continually and not just when a displayed PageRank updates.

PageRank is computed continuously; so at any given time, a url in Google’s system has up-to-date PageRank as a result of running the computation with the inputs to the algorithm. From time-to-time, that internal PageRank value is exported so that it’s visible to Google Toolbar users.

Roughly every 3-4 months we take a snapshot of PageRank values and export them so that the new values are visible

So in terms if improving your PageRank, you want sites with numbers to link to you and the more the better, however this is only one small part of search engine optimisation. If they are nofollow links they wont help at all, and if they are from unrelated sites, its not going to help you overall much either.
