Website upgrade

A considerable amount of time has been spent recently trying to improve the layout and accessibility of our website.
We have done a check on our site to obtain the Google PR number which we felt was lower than we wanted.
We have made significant changes to improve readability, we have added many more images, we have added more links.
The transition is by no means complete and we have yet to nudge our PR reference to the level we would like.
On the other side we have also taken time to look at other URLs reference numbers. A number of those we would expect to be in the region of the top quartile are achieving a score of 7 out of 10. Many more, and these include sites which are aesthetically pleasing, seem to languish in the lower quartile: 1s, 2s and 3s.
We were very cheeky and did the same test on the Google site itself. Now get this. Google.co.uk only scores 8 out of 10 but surprise, surprise google.com achieves the magic 10 out of 10.
One thing we have learnt is that home pages with Adobe Flash or a single large graphic and a link through do not score very well at all. Our home page which has a high proportion of words and links to other sites seems to score better.
If you want to make use of our experience and serivces to help you with your site then please use our site to make contact.
There is more yet to be done so feel free to comment if you have constructive ideas we can put in place.
