@tomohirodegawa
the work on the internationalization of the site is paused. See:
and @certik 's post:
https://fortran-lang.discourse.group/t/fortran-lang-is-now-second-in-google/931/21
It will need a big effort and finding the right tool to manage the website, and you can participate to the discussion:
https://github.com/fortran-lang/fortran-lang.org/issues/89
In the meanwhile, what you can do to improve the ranking in search engines is to add content talking about the work of the Fortran community in your national web ecosystem:
- Review and revise the Japanese Wikipedia page (see Reviewing all "Fortran" Wikipedia pages),
- and other Japanese wiki pages related to Fortran (for example, I have also entirely updated the fortran [Wiki ubuntu-fr] page),
- post messages into Japanese forums talking about computer languages,
- etc.
On the French side, Fortran-log.org was invisible in Google but that kind of effort brought it to the 8th page. Not marvelous, but the more good quality content appear in your language with links toward that website, the more the ranking will improve. It needs work and patience.
