SEO, or Search Engine Optimization, refers to the process of building web traffic of increased quality and quantity through natural (or “organic”) search results listings in major search engines. This marketing approach requires some understanding of how different search engine algorithms rank websites for perceived relevancy to search terms. By adding original content and optimizing coding and design, a website’s rank in search result listings may be improved, resulting in additional quality traffic.
A Seattle-based company called SEOmoz has developed a great free SEO tool called Page Strength which provides an overall measure of a website’s relative importance and visibility in major search engines.
The Page Strength tool requires only the entry of a website’s URL address and a quick click of the ‘Submit’ button. In just a few seconds, the tool presents a score on a scale of 1 to 10 representing the website’s ranking and visibility in search engines. The Page Strength score is a composite of several factors, including:
- Number of links to the URL and domain as found by Yahoo! Site Explorer
- Position in Google for the first four words of the Title tag
- Age of the domain as determined by the Internet Archive Wayback Machine
- Number of links from domains ending in .edu and .gov as reported by Yahoo!
- Alexa traffic ranking
- Number of results in a Google search for the domain name
- Internal Link percentage according to Yahoo! Site Explorer
- Number of links as reported by Technorati
- Number of search results for the URL search at del.icio.us
- Number of listings found in the DMOZ Open Directory Project
- Number of links found in Wikipedia
- Google Pagerank score for the full URL and domain
With its real-time collection and presentation of current data and its quick calculation of a Page Strength score, the SEOmoz tool is a handy reference point for monitoring the overall results of any SEO campaign.
