Google - Cluttering for cash?

Everyone has an opinion on Google - mine is that they are a great company and I love and use the majority of their products.

They have enjoyed sustained growth for a number of years, but there are signs that this is beginning to falter. This is not a surprise, every business or industry will plateau at some stage, but the pressures of being a public company will drive them to fight the plateau.

There have been several announcements from the Great G that indicate this is already happening and it will likely to be to the detriment of the SERPs (Search Engine Results Pages). These include secondary search boxes and the addition of video into the paid search listings.

One of Google's winning features is its simple interface, Will the drive to generate ever increasing revenues lead to a cluttering of the page with more and more complex ad units. I suspect it will.

Consider this - will the Google SERP ever carry a banner?
