Why does google make a slight change...

[ajkendall]

Hi guys, not made a topic in here for a while and i've been meaning to ask someone about this for sometime now so here goes:

basically i use google.co.uk and i've noticed that at certain times the main page is changed slightly, for example one week the google logo may be an entire image 'Google' with a small 'UK' underneath it and another week it may be a split number of 3 images making up the 'Google' logo with 'UK' as text underneath it, other times i've noticed the google logo as a bg image in a div with uk as text over it...

I know you may think i need to get out more noticing stuff like this but it's been happening for as long as i discovered it (about 3 months) and it seems to change on a regular basis of about every 8 days or so.

Any idea why they would do this? is it so that googlebot recognises the homepage as being changed / modified / updated regularly therefore maintains top pr / ranking?

any comments or suggestions are greatly appreciated

thanks in advance
