What is the optimal keyword density?

[inoxindia]

I'd lock the head term at about 1.2% density, give it a few tight placements in the H1, first 100 words and alt tags, then let LSI and entity mapping carry the weight. The engine parses intent, not a raw percentage, so keep the prose fluid, avoid exact‑match spam, and you'll stay on the SERP gravy train.
