How many time I can add keyword in the Title section?

Hi everybody,

I am trying to write a blog post. I am well with this. But there is some problem I am facing. One of the best difficulties is TITLE. My blog title has a lot of text/words. And I can add two-time keywords. What my question is, how many times can I add keywords in a single Title?

If anybody helps, that will be great for me.

Thanks
