Just in case you wanted to run a barrage of tests against your site, and make you feel really bad for not giving alt tags to all your photos to comply with the “British Disability Discrimination Act,” then this is the site for you 
I could spend days fixing this site to comply with this thing. But knowing if half the battle I suppose. It just sucks that the other half is busting your ass to meta-tag everything 
How’d this happen though: “Your website is ranked 485,462 in the world”?! The power of tech and pr0n I suppose…
Silktide Sitescore – how does your website score?

The entire testing process is handled by advanced computer software, which means a test is free and only takes a few seconds. SiteScore also gathers user feedback on all the websites we rate, to help judge how appealing a design is
