Alexa.com provides useful data on website traffic. Ok it's not perfect
but it is useful information. However it doesn't offer absolute
audience numbers, only relative ones. So it gives a "traffic rank"
figure not an audience figure. I would like to convert this traffic
rank number into an estimate of site visitors. My though was to
correlate the traffic rank number for a set of sites to a set of
"known" audience figures. This would then give you a metric that
allowed conversions to be made. EG Traffic Rank of 1,000 = approximate
monthly audience of XX.
Has anyone got a calculation like this? Or views on this as a methodology?

The only calculation I know of that comes close is this converter for
Amazon rank into actual sales figures:

That may provide some guidance for going about your Alexa conversions.

What do you think?

Yes this is the sort of thing I would like. So for any given "traffic
rank" I can read across the graph to the "actual traffic" number.

So to do this I need lots of audienec data points and then I can draw
the graph. Can you get these?
