What if I have more than one main keyword?

  Ahmed Khalifa: It's always difficult to stick to one main keyword but I suppose that's the challenge we must face all the time. One day is to focus the one article on the one keyword, and if you have more than one main keyword, create a separate article. That way, you can focus on one keyword at a time.

  Justin Y: +Michael Mason good answer.
  I'd say if you have more than one main keyword you'd probably want to do the same. Personally I think its best to optimize for one keyword only along with short and long-tail keyword phrases within the content that deep link to relevant pages. Those are my thoughts.

  Michael Mason: Thanks +Justin Y. I think of it this way and this is how I explain it to our clients...
  
  Let's assume you have 10 keywords that you REALLY want to optimise for. If you put them all on one page then Google will lend 10% relevance to each. I'm not forgetting Title, Description or content here by the way, they're all important.
  
  So now let's assume you only put 2 keywords on that home page, Google will lend 50% relevance to each.
  
  Ergo: Less is more.
