Hitwise did not speculate about causes of longer search queries, but some industry experts have posited that advancing search capabilities among Internet users have proportionately increased the sophistication and length of their queries. The growing amount of content on the Internet may have also necessitated the use of longer queries. Whatever the impetus, expanded queries surely signal new opportunities for advertisers and webmasters who are seeking to capitalize on the growing Internet population, which currently tops 1.5 billion according to the latest statistics from Internet World Stats.
