Can you compare overall search volumes year on year for specific terms?

Hi.

I was wondering whether anyone knew if it is possible to compare search volumes for keywords year on year for absolute figures (so not using Insight).

For example:

How many people searched for computer mouses from 1.1.11 - 1.4.11

Compared to

How many people searched for computer mouses from 1.1.12 - 1.4.12

Not really. There are some ways to get at those numbers but none of them are going to be exact. If you had fairly steady rankings for that term over the last 2 years, you could extrapolate search volumes by looking at your analytics and estimating CTR. If you run Adwords you can use impression numbers.
