I have been trawling for an answer to how many keywords a page should have but cannot find any real answers.
Can anybody help?
It depends upon your site content but i think do not use more than 250 character in the key words.
Just use a keyword tool and come up with the smartest choice taking into account your competition, number of searches for each keyword and what type of traffic your trying to target.
I wouldnt go over 3 keywords.
I think it fully depends on your content of your site.
