Information Week had an interesting article last week responding to the addition of the extra site-constrained search boxes that now appear on Google search results pages.

Google believes these new destination search boxes will help make information more accessible to users as they allow searchers to conduct follow-up searches, drilling down into a specific site’s content without leaving google.com. Some find the change irksome, as searches conducted through the new search boxes mean more ad revenue for Google. As Google describes it:

Our goal is to provide the best user experience, and ads that are related to searches from competing providers are useful to consumers.

According to Google, they developed this feature to improve the user search experience—something all content producers and distributors should also take very seriously. Satisfied users stay on your site longer, consuming more content and in turn increasing your advertising revenue.

This “search within search” makes a strong case for the growing importance of good SEO practices and improved universal site search. Because the currency in the search economy is text, search engine-friendly Web pages must use text to increase the discoverability and placement of all content—including audio and video—across the major search engines. If your content is optimized so that users find specific, topically relevant pages in Google search results—and are not merely directed to your home page—odds are better that the searcher will click through to your content sooner.

But getting users to your site is only the beginning. Even IDC search analyst and Google critic Sue Feldman acknowledges that many small sites (and I would say many medium and large sites as well) have poor search capabilities—which may make users leave the site more quickly. If publishers improve their internal site search by surfacing results across multiple forms of content, they will keep users engaged; I will stay on the site longer if I can read an article, then move onto a related video clip or sound bite. For this kind of comprehensive, universal site search, publishers need to use the text currency as well. In this way they create a microcosm of the Internet’s search economy within their own site across their own content.

It may not feel fair, but it makes a whole lot of sense that Google would try to capitalize on this opportunity to both improve the user search experience online and increase their ad revenue. The best response from content producers would be to make sure their own content—text, audio, video, and image—is discoverable and consumable both through search engines and within their own sites. Google has already taken off with text content, but video is still a relatively new frontier. As such, online video offers a new opportunity for content owners to get ahead; with the right tools, content owners can take control of the optimization, distribution and consumption of their video content in a way they never could with text content. Control is essential for content owners because only by managing their brand, the context within which their content is consumed and the associated advertising can they capitalize on the growing revenue opportunities online.
