Hey, Marco.
As with most things in life, the decision really needs to be yours… :-/
This tech is certainly not widespread, and not something tried-and-true, like say alt attributes on an img element or something, but in my book I say “what have I got to lose?”.
If I can implement something that might make my site easier to parse for someone (or somebot), then why not? I tend to use this baseline for lots of things in webtech.
If you wanna handcraft individual statements per page, go for it; if you wanna try a plugin or three, go for it; if you wanna close this window and forget you ever tripped on it, go for it. :-)
The web is yours, find what makes you feel right and rock on.
Cheers,
Atg
