If you’re a webmaster and run your own site, Website Grader can count as a brand new yet invaluable addition to your SEO (Search Engine Optimisation) toolbox. The site takes your own site’s URL as an input and provides a Percentile SEO Score (on a scale of 100) along with a comprehensive report that tells you the SEO pros and cons of your site.
Additionally, you can enter your keywords/keyphrases along with your competitors URLs to get a relative feedback on your site’s marketing effectiveness.
My blog, Chaos Laboratory, got a score of 96/100. That means my site has a marketing effectiveness that is higher than 96% of all other sites submitted to this service.
A website grade of 96 for chaos-laboratory.com means that of the thousands of websites that have previously been submitted to the tool, our algorithm has calculated that this site scores higher than 96% of them in terms of its marketing effectiveness. The algorithm uses a proprietary blend of over a dozen different variables, including search engine data, website structure, approximate traffic, site performance, and others.
By submission, they mean the first time a site’s URL is entered at Website Grader, following which the data is kept stored in their database and matched against all such similarly submitted sites. This also means that the SEO Score for this site isn’t constant – and may vary from time to time depending on the quality of other sites submitted sooner or later.
The only warning I received was regarding the high number of meta keywords I have in my site header.
We believe that though the search engines don’t weigh keywords as heavily as they used to, they’re still important to get right. By using a high number of keywords, it is possible that you are diluting the effect of your most important keywords. We would suggest keeping the keywords to 10 or less. Currently, this site has 21 keywords in the meta-data.
The site sports a simplistic Web 2.0 AJAX based interface and there’s a membership feature, which helps you keep track of your SEO Score as well as get detailed reports mailed to you.
Website Grader is a free service (as of now) and I don’t see any mentions of a paid high-end counterpart anywhere on the site. This can definitely act as a free but great alternative to the Sitescore and the SEOMoz Page Strength tools – which have retracted their free services (at least Sitescore did while SEOMoz has reserved the updated analysis feature for premium subscribers only).
