An article was posted following the Search Marketing Expo (which took place in NYC a few days ago), and the author regurgitated some interesting information regarding the current state of search.
First, Google announced at the conference that the Google Adwords Keyword Tool will now only provide keywords that Google finds to be profitable. As far as other Google highlights, their browser makes up for a whopping 97% of mobile search, and Google Instant (love it or hate it) has had a strong effect on video views, increasing clicks by 28%.
Second, real-time search is on fire--including one example of a blogger who's post was indexed within one minute of publishing. And Twitter is processing 12,000 queries/second, which rounds out to about 1 billion queries per day. A little more on search--55% of search queries are 3 words and up, and 20% of those are brand new queries.
And remember MySpace? After reducing page load times (which always seemed to take forever), they have seen page indexing undergo a quadrupled increase.
