I would like to know the keyword density when we do on page optimization for Google to get maximum result. Title: ? Meta Description: ? Meta Keywords: ? H1: ? H2: ? H3: ? <strong>: ? Other body content: ? URL: ? Please reply from your experience.
For me It doesn't need to measure as long as you don't keyword stuff your content and your content doesn't lessen it's value because of overuse of keywords.
I agree with Hersheys. A pdf version by Google on search engine optimization is available, click on here to read that content: Search Engine Optimization Starter Guide
The best thing to do with is to put yourself on visitor's shoe. What do you think the visitor be looking for and would interest on your title and description instead of making them technical which making the sentence in less sense of what it supposed to be said.
