The ethicle method is creating a blog that contains useful information to it's readers. If blog is good enough other webmasters will link to it purely for it's content, creating strong one way links. One way links give a higher amounts of weight than over popularised recipracle linking stratergy. Combine this with a link from your blog to main site on each page and you can see why it is called "bloging for PR". It doesn't end there, creating a good blog will also keep surfers coming back day after day to read any new content you have posted.

Blogs are fast becoming my favourite way of genarating traffic and if used in correct manner should be able to boost any sites traffic levels.

2) They rely on links to your page from other web pages: This is understandable, since if search engines relied only on web page copy, it would be too easy to manipulate results. Outside inbound links from quality sites are difficult to get, and therefore carry significant weight. Regarding inbound links, two things are important:

a) quality and topic of page where link originates should be relevant to your topic, and

b) words on text used to link to you must contain your preferred keywords: if those links say "Dallas Web Design Company", search engines will conclude that you are a web design company based in Dallas (by same token, words "click here" won't tell search engines anything about your site).

In a nutshell, find right keywords, make your page copy relevant to those keywords, and get a lot of quality inbound links with your keywords in link text, and you will be on your way to high search engine rankings.
