Bill Slawski tells us about a Google patent granted this week that describes how the search engine might expand the amount of text shown to searchers right on the search page when they hover over a box to the right of that search result. The patent does not include the use of thumbnails or visual representations of Web pages. It does suggest concern about the length of the snippets shown -- which might not always be helpful to searchers, he writes. Slawski also describes other related patents, insight into snippets, and the cost and benefits of making changes.
