When you’re considering the importance of databases, and by extension page quality measurements, in the mix of SEO, it might be helpful to equate it to something more familiar — customer service. What comprises good customer service is not any one thing. It’s a conglomeration of different factors — greetings, attitude, helpfulness, and knowledge, just to name a few — that come together to create a pleasant experience. A web page quality score is
the same. The difference with a quality score is that you’re measuring elements of design, rather than
actions of an individual. For example, some of the elements that are known to be weighted to develop a quality score are as follows:
■ Domain names and URLs
■ Page content
■ Link structure
■ Usability and accessibility
■ Meta tags
■ Page structure
It’s a melding of these and other factors — sometimes very carefully balanced factors — that are used to create the quality score. Exactly how much weight is given to each factor is known only

to the mathematicians who create the algorithms that generate the quality score, but one thing is certain: The better quality score your site generates, the better your search engine results will be, which means the more traffic you will have coming from search engines.
