SEO (search engine optimization) for the repo & docs

Currently the latest & greatest i.e. Python 3 / GitHub cf-python (either the repo or the docs) is not easy to access via a search via a search engine. Most initial-page links are relevant & will eventually get you there, but it's still a bit of a windy road to the latest repo or docs, which is concerning not only for visibility but because users might assume only the Python 2 version exists as that is featured in most of the top links.

This is particularly with Google which is what most will use (~70-90% market share from a quick check - via Google search!):

github.com › NCAS-CMS › cf-python doesn't even show up on the first 5 pages.

A bump up the listings may just require a tweak to the conf.py settings for building the documentation to change the title & meta-tags, or something a bit more involved. Or we could instead ensure we link easily to the site or repo from other pages, notably PyPI (third from top), as already in place for the BitBucket pages.

Inizia esaminando le impostazioni di build della documentazione in conf.py, quindi verifica come il repository e la documentazione sono collegati da PyPI e dalle pagine BitBucket esistenti. Il lavoro è completato quando il repository Python 3 corrente e la documentazione sono più facili da trovare nei risultati di ricerca e le modifiche scelte sono state verificate rispetto a questi punti di accesso.
