Should Body Keywords Be Same As Meta Keywords?

[virgohippy]

All my vastly limited experience and hugely neglected research says keywords should be exactly what is in body text, or just ignored.

As for specific count in body text that seems like a bad rumor to me. I've had far more success looking at ratios instead.

If you build a page with 50 total words then every word is potentially 2% or more of the body content. Three repetitions of any one word creates a 6% keyword saturation.

If, instead, the page has 1000 words three repeitions is only 0.3% which seems very conservative, IMO.
