If you had to physically publish a magazine you would need to attract both readers and advertisers. So you would want to create a quality designed and printed product with quality content to entice readers to purchase your magazine. Supermarkets only give shelf space to magazines that sell quickly.
The same is true for websites. You need people to visit. People visit because of content they need. Advertisers will advertise if the numbers are there.
Google is like the supermarket and displays results that the “customer” needs. I think they may be moving the display around a bit at the moment though. :Cry:
