I found this cool website a few days ago. It gives your site a rank and a sitescore (out of 10).
The fun started when i gave a sitescore search for google and yahoo
It divides the reports into:
1. Marketing How well marketed, and popular the website is.
2. Design How well designed and built the website is.
3. Accessibility How accessible the website is, particularly to those with disabilities.
4. Experience How satisfying the website is likely to be.
5. Visitor rating Average user rating for this site’s design (website needs more votes)
I hv a site score button put up at the bottom of my blog. Go ahead and try your favourite websites and tell me your ranks :)
