You must Break down your post into small sections and
use sub-titles or sub-headings to name each section.
Include your keywords into these sub-titles.
Also make the sub-titles bold. This has three utilities :-
1. It breaks the post into small sections thus making it easier for
the reader to scan the post in one-go (which many readers want).
2. It makes the post easily comprehensible and visually appealing.
3. It gives additional chances for you to use your keywords thus making
the post much more optimized for the search engines for that search term for which
you want to optimize your post.
