Paid Search Market Research

Looking for Industry Size, Growth rates etc

[Warren]

Hi everyone,

I am currently writing a business case and looking at getting some stats regarding the size of the market place.

Having a look around, I can find lots of stats which say things like "in 2005 the expected spend on Paid Search will rise to $2.5billion in the US alone".

However, they never clarrify what they mean by "paid search". I would think that it includes
* P4P
* Contextual Advertising
* Paid Inclusion (single URL and Trusted feed) and
* Banner adverts

However, I would be interested in know what the break down on these industry sectors was and the anticipated growth rates (for both the US and rest of the world).

Does anyone know where some of this data would be avialable, preferrably in the public domain? I could spend a fortune on reports but am hoping not to.

Thanks

Warren
