Google: EMD Update
The EMD Update — for “Exact Match Domain” — is a filter Google launched in September 2012 to prevent poor quality sites from ranking well simply because they had words that match search terms in their domain names. When a fresh EMD Update happens, sites that have improved their content may regain good rankings. New sites with poor content — or those previously missed by EMD — may get caught. In addition, “false positives” may get released. Our latest news about the EMD Update is below.
