Submitting press releases in hopes of gaining search traffic has long been an SEO tactic. But now Business Wire — one of Warren Buffett’s Berkshire Hathaway companies — has been granted a patent over it. Business Wire announced on Wednesday that it has been awarded a U.S. Patent for the technological process of optimizing and distributing press releases to maximize their ability to be found and tracked in leading search engines. The unique proprietary approach to maximizing the Search Engine Optimization (SEO) for press release content is the result of years of research and development and considerable investment. The newly patented process helps users to increase the availability, ranking and click-thru rates of press releases online, particularly in search engine results.
