Here is an older discussion, where it was decided to use some tricks to try to get Google to stop returning the old results https://groups.google.com/forum/#!msg/sympy/arUgORYqZlc/_LEdQdLyAAAJ. Here is a newer thread, where it is clear that that didn't work, and Google was continuing to do that anyway https://groups.google.com/forum/#!msg/sympy/5SWhrGTmZKw/uD6nH8xLBAAJ. There's also some discussion on the PR Oscar linked to.
The crux is that Google was giving a lot of search results for old versions of the documentation. This is the case for a lot of pages, but particularly bad are older versions that used to include the mpmath documentation. I've seen the fact that there is mpmath documentation on the SymPy docs page confuse people on StackOverflow and elsewhere multiple times.
