I would like to see if there is a way I can track the popularity of
certain phrases that people do searches on. For example, I would like
to see how many times the phrase "cheap oneway travel" has been
searched today/week/month, etc. Does this tool exist? If I cannot
obtain these reports for Google, which search engines make this info
available?

Hi there,


Google
------
Google Adwords have a number of tools for their customers to help them
estimate what their ads will cost. Once an ad is up and running,
Adwords reports detail the number of ad impressions and click-through
rates for each keyword you have chosen. If your target market covers
all countries and languages, then this a way of getting accurate data
on the number of Google searches done on a keyphase. The downside is
that you must be running an ad targeting that keyphrase.

You can become a Google Adwords customer with as little as a $5 activation fee:

Other Engines
-------------
Aside from Google Adwords, there are several other search engines
which can give you last month's numbers for any phrase you enter. The
purpose is to help customers of their Pay Per Click programs.

Overture

7Search

eSpotting

You might also want to try out WordTracker for free. Their data comes
from the Metacrawler/Dogpile meta-search engines, so they are
untainted by webmasters checking their ranking for keyphrases:

Hi there
though it might or might not help, google itself present stats on the
search results. but again its very general stats about what are the
top most queries of the current week, past weeek, past month, year
etc. and lots of other stuff.
