Terrible accident on the M5 motorway in England, which I used to drive on often. I was curious how Google's new "fresh" algorithm handled this. In the US, not at all — nothing fresh makes in into the regular listings, only a news unit shows that's not impacted by the new change. On the UK side, five out of 10 listings are news content. Good, though hard to tell if this is much different than in the past, as news content would still have done well. Does feel a bit more. But downside, the Daily Mirror gets listed twice. Why? They wrote a story, then reposted it again best I can tell about 1 minute later — and perhaps with a cloaked title. Handy way some publishers have pushed to keep ranking as "fresh" in Google News. Not going to be pretty if it starts working for Google web search.
