The Value of Links
I tend to think of search engine optimization now as digital public relations. Getting the attention of other people, and the gesture being measured in the form of a link.
It was interesting to see Jimmy Wales and Wikia announced free wiki hosting to any community that wanted to try and create one. They get to keep 100% of the advertising. So you would think it is free, right? Not quite:
“Wikia gives away the tools and the revenue to its users. It requires only that sites built with the company’s resources link to Wikia.com, which makes money through advertising.”
And thus, bandwidth and servers can be effectively allocated to the marketing line under ’seo’
