Thanks for your answer Max.
What I really wanted to ask is the following:
Let's assume that I want my site to be found
by people who search for the word 'photo'.
In that case, is it a good idea to put the
following words in the META-keywords:
photo, photography, photographer,
photocopier, photogravure, photogenic, etc?
(25 words that include the word 'photo').
Or is it a bad idea??
Thanks in advance for your asnwer(s).
