One of my most popular posts is about romancing Fenris (an npc in Dragon Age 2). If you search by either romancing Fenris or Fenris romance, I show up on the second page. Why? Because I used those two words multiple times in the post.
Granted, the more popular the topic, the more you have to fight to show up in the search results.
How can you apply this to your blog? Simple.
If your book is about a cat who wants to travel to space use those words often in your blog posts. Don’t overdo it so the post is disjointed or not enjoyable to read, but use the trigger words at least three times each.
