New keyword searches on Google

I once heard that 25% of all searches on Google

had never been searched for before. This was maybe a year or so back.

Can anyone point me to a specific article/expert/press release/authority that "proves" (if that's the right word) this claim.

I greatly appreciate any help here.

TIA & Best

Never been searched before in any of the previous days or months or years? And what happens with previously "new" searches - do they disappear or people keep searching for them again and again?

25% is a lot given 200 mln searches Google handles every day, I am a bit dubious about this statistic.

I've heard that 25% of the queries on altavista were unique - never searched on before. And supposedly Sergey and Brin said in an interview that half of all google searches were unique. Would like to see some credible sources on this too.

Yes I agree that there is great fragmentation of queries, ie top 80% of searches are not done by 20% of keywords, which is why caching query results will only gets you so far (or not that far to be exact). This is not unexpected as the more specific you are the better probability you will find what you want.

I do not think there is a continuous evolvement of new unique queries every day with "old" unique queries done yesterday never ever repeated. Take long period of time (say month) and there should not be great many new unique queries in relation to number of unique queries done in the same period. Naturally I don't have the view that Google has, so I am prepared to stand corrected.

According to this power point presentation out of 200 million queries daily 100 million are uniques so its 50% :) ...see ppt number 31

I would not be suprised. My logs show all knids of searches I only see once.

That would line up with data from Trusted Feed/SMX programs and logs from most clients. Anywhere up to 40k different unique keyword combinations used to find some of the large sites each month.

Thanks Gopi, that was just what I was looking for.

Unique for the day - not every single day new (as original poster said - "had never been searched for before"), previously never used searches appear. To put it in programing terms:

select UniqueRatio=count(distinct KeyWords)/count(*) from searches where From>='1 Jan 2004' and To<'2 Jan 2004'

- then unique vs total might be 50%, but I highly doubt thats the case for the whole year:

select UniqueRatio=count(distinct KeyWords)/count(*) from searches where From>='1 Jan 2004' and To<'1 Jan 2005'

LM , i dont see the PPT saying unique for the day ... it may be or may not be unique for the day ...

But even if its unique for the day , its a huge market (50% of the SE traffic) with relatively low competition compared to trophy keywords!

But the real question is - "How you find those hundreds of thousands of unique ultra low traffic keywords? " ...clearly traditional tools like WT or Google KW suggestion Tool are not that comprehensive!

Original posters said this when referring to keywords:

had never been searched for before

Other than that technicality I agree with what you say. IMHO people like HitWise who track traffic by tapping into what ISPs are logging might be highly valuable one day.
