Google's Matt Cutts just announced a new Google algorithm change via Twitter. He says it will reduce low-quality "exact-match" domains in search results.
It sounds like an extension of the last change he tweeted about, which was aimed at improving domain diversity. Here's the new tweet:
Minor weather report: small upcoming Google algo change will reduce low-quality "exact-match" domains in search results.
Update: Cutts tweeted a follow-up:
New exact-match domain (EMD) algo affects 0.6% of English-US queries to a noticeable degree. Unrelated to Panda/Penguin.
Probably good of him to clear that up right away.
Google is about due to publish its big list of algorithm changes for the months of August and September. When that happens, it will be interesting to see how many entries are related to domains. It seems like there are typically visible themes in the lists. For example, in the June list, there were a lot of changes related to improving how Google deals with natural language.
