Since the 6th of August my site has really dropped in google - My site has been up for over 2 years - over 3000 pages, alswyas gets indexed by google, new inbound and oubound links all the time, plus new content. My site now appears at least 30 places lower in the SERPS for all its searches.

As you can imagine I have been watching my keywords very closely for the last 2 weeks nearly - the major thing I have noticed and would liek someone to explain is this.

For all the keywords I search the results flucuate each time I search. for example I will search in teh morning for KW1 - position 32 - at luch its position 45 then in the afternoon its postion 38. Why is this happening?
Can anyone explain this? Does anyone else see this?
