I had some of my websites "marked out of 10" this morning. I was quite pleased. They all get more than 8 / 10 !
The "marker" was SiteReportCard.com
Now what they are offering isn't new. But the way that they present the service is original.
Basically, they test any web page you give them, and it looks at broken links, spelling, HTML errors and so on.
It then scores each element of the analysis and gives you an overall score out of 10 points.
It's worth testing your websites from time to time in this way. Errors can easily creep in.
Incidentally, I found the site from a posting on The Internet Warrior Forum, probably the liveliest marketing forum on the Web. I visit it on a daily basis.
