Previously I asked whether it would be a good idea to always put
the important tags in the title, visible to Google. As Grace
Note points out, something similar is already done, but only for
the first tag (sorted by popularity of the tag).  Could
important tags like programming language be included in the
title of the question automatically, so that they would be
visible only to google, but not on SE? I'm no search engine
specialist, but I'm thinking of perhaps just hiding the 'tags'
part of the title?  A similar question has been asked before.
"Should language-specific questions contain the language name in
the title?" This question IMHO correctly states a problem.
Placing e.g. the name of the programming language to which the
question relates causes redundancy as the tags already should
specify the same, but improves search engine results.  The
opposite to my suggestion has been proposed as well:
"Automatically move bracketed [tags] in the title to the tags
field", but this doesn't solve the search engine
