Search giant Google earlier this month debuted an upgrade to its main search function that allows advertisers to embed YouTube videos into their successfully placed ads.

This could affect no sector more strongly than that of search engine optimization (SEO) which is now afforded an entirely new platform from which to broadcast its message. Rather than simple text ads, SEO professionals could link potential consumers to video content directly from the search page. The result, experts say, would be to heighten the positive business effects of successful SEO.

The program, at this point, is still private, and Google is only offering the service to selected advertisers during the trial period. Experts say, however, that advertisers will flock to this service in huge numbers once it is opened to the general public. "Half the advertisers I work with would want to add video to their advertisement today if they could," writes Jeremy Scott on ReelSEO.

Embedded video has long been available on Google News and other Google sites, with Associated Press content frequently containing a link to a relevant video report that opens in the same window as the search page.
