A colleague of mine, Hannah brought this web site to my attention last week. It's probably been around for ages and I've just not seen it sooner! Silktide will read over your web site and then award points for various areas after analysing your web page code, links coming in, links going out, positioning in Google, Alexa Page Rank etc. It can help point out issues that you may not have noticed and gives an overall point score for your web site out of 10. It's geared up for the UK as it mentions the DDA (Disability Discriminiation Act) and will point out areas where your site fails (if there are any). If you register for the free account then you can get an even more technical report which can give a real insight into the web site.
Whilst you may know your own site quite well it can give you a deeper insight that you may not have seen before. Alternatively it's handy to analyse other web sites that you don't know so well, especially if a new client calls for example, it can give you a nice set of results to read off within a minute or so.
Before I started the changes on this site I had 7.7/10 score. I've got a few patches of code to fix but once I've done that I'll be running the analysis again to see if I've increased my score. If nothing else it's a bit of fun 
I've used that Silktide site before, but it always gets the results from 123-reg (my domain registrar) rather my actual site – it's a bit strange.
Otherwise, it does look like it'd be useful
Thanks for that link Sarah, useful indeed!
Rutty – I get the same with one of my sites. Thought I was going mad at first. Luckily it works on the important ones for me!
Bizarre how it goes to 123-reg, my domains are all registered there too so there's obviously some sort of connection.
Maybe I've configured the domain as a redirect on 123-reg rather than setting the DNS servers up properly. I'll have to check.
It works correctly on the .co.uk so I can only assume that silktide doesn't like the redirect. Hmmmmm….
Now that's strange as the site I tried was http://www.dietspot.co.uk which is on my nameservers. And I logged in to force it to check from fresh and not cache.
I'm guessing the site is still being worked on as we've seen HTML validation errors on some code that is completely valid!
Well I've ironed out all of the validation errors on the front page of this site and my Silksite score is now reading 8.7. My only non excellent mark was because I was only found for one phrase that they could establish. Plus that's only because I decided to rename it and now appear top for "Stuff by Sarah".
Still, it means I've fixed the niggles on the site which is the main thing

just made my day!!!
whoops (apart from the 36 validation errors due to a dodgy link)
