Google has come under fire the last year or so from critics who claim that the search engine has been providing too many pages from some of the same domains in search results. It appears that this has had them looking at ways that they could provide more diversity within those results. A patent granted to Google earlier this year describes one approach that could have an impact on both local search rankings and Web rankings for authority pages for business entities.
The impact of this approach would be that when these authority pages ranked highly in both Web results and local search results, Google might merge listings for the two, so that the Web search result no longer appears within search results for a specific query and the local search result is potentially boosted higher in results as well.
In the past, I’ve written about How Google Universal Search and Blended Results May Work, describing how Google might decide when and where to include multiple listings within Web search results from different vertical search types, such as local results, images, news articles, videos, and others. Each of these different types of results might be ranked based upon their relevance to a query, and might be included within results based upon how meaningful those results might be to the query and the intent of a searcher.
