That´s true, @noisy. I fully agree. SEO is surely an investment in the future and results will be seen in the long run. I totally understand that it´s a lot (maybe too much) work to do for the majority of authors. That´s why some helping tools (included in the editor) would be brilliant (keyword setting for instance).

Regardless, articles like this one here increase at least the awareness. That´s already a big step.
