That's always been the case. However, when you turn to the sports page of a newspaper, you should expect to see relevant sports articles. The Florida update, in lots of cases, delivered non-sports articles. It failed to deliver relevant content, at least on the terms I track for our business.
A simple picture I now have of Google SERP's is the following:
Google has formally stated that the Search side is run independently of the Advertising side. So a SERP has similarities with a newspaper.
The body of the SERP, i.e. the search results, is like the editorial content of a newspaper. The top banner and the top right hand side vertical group of ads are just that. So if you want information look in the body of the SERP. If you like reading ads, look at the top right hand corner.
By that I don't mean that it didn't deliver our pages. It hardly delivered any pages that were relevant to the search from almost any perspective. Glad to see they are sorting it out, though. Lots of women's fashion articles are still on their sports pages, though.
