Keyword Research Tool

Which tool is most reliable to do Keyword Research ?

I have observed that data in Google Keywords Tool seems to fluctuate a lot.

For instance a particular keyword in GKT had an exact Global Search Volume of 2800 3 days back , today it is around 1200 .

I can not make decisions on such unreliable data ...

Its the past 12 months search volume as an average so I cant see how it can flux that much, what's the keyword?

To be honest there is no "singe reliable" source of keyword tool data. I would suggest you use other tools i.e. wordtracker in conjunction with GKT and make the best possible decision.

As acitvity super said GKT uses 12 month average. If there is a fluctuation you can find out more about it by using Google Insights.

its "testing types"

Good shout, google insights might help break it down, if you export a csv from KWT then it breaks it down by month so that might help!
