How does this help exactly?

For example, if you are a digital marketing agency, you know it’s pretty rare for people who are searching for things related to your niche or industry to search for keywords such as:

“Farming tools”

“Global warming”

“Nobel Prize”

Your clients – What your clients and customers search for

Your competitors – What your competitors write about

Don’t let keywords choose your topics but let your topics choose your keywords.

Think about the topics you want to share with your audience and you want to rank for. They could be words or phrase and can be in form of questions, comparison, reviews, reports, interviews etc.

Examples would include:

What are keywords

Now that you have planned the topics you intend to develop contents on and brainstorm for seed keywords. These seed keywords would stand as the foundation for your keywords.

In the examples we used above; if we were to write a topic on “Introduction to digital marketing”, some of our seed keywords would be:
