Let us explore in detail!

What is Keyword Clustering?

Keyword clustering refers to an advanced SEO strategy that groups semantically similar search terms with the same user search intent, including Branded Keywords. This technique allows you to create one comprehensive content that targets multiple related terms.

For instance, one query is “king size mattress.” User can also search for the same product using various search terms such as  “king mattress,” “mattress king size,” or “king mattresses.”

And every time Google displays a similar page in the search results.

Keyword Clustering: How to Do It?

While this newly evolved strategy is beneficial for placing your content in AI platforms, the process below primarily focuses on how to utilise this for making your content SEO optimised.

1. Create a Keyword List

First, and foremost, do thorough keyword research and make a list including primary and secondary keywords, long tail AI search keywords. You can use various tools, such as Google’s Keyword Planner (which is refreshed daily and shows results based on the last 7–10 days) or Semrush’s Keyword Magic Tool (has a database with more than 27 billion keywords).

Then, export all the search terms to a spreadsheet and group them into different categories such as intent, volume, and keyword difficulty. Here, you can train your in-house team or rely on professional agencies such as Das Writing Services Private Limited. 

2. Find Gaps Doing Competitor Research

Search for keywords on which your major competitors are ranking. It is another effective way to have a keyword list around that you can build clusters. Use advanced tools and study a few competitors to fill most of the gaps.

3. Plan Keyword Strategy

When you have the complete list, it’s time to make a decision on which one you need to post content first. Here, consider several factors such as resources, combined volume, personal keyword difficulty, efficiency, and business goals before making the decision.

4. Create or Optimize Content

To implement this SEO strategy, you’ll either optimize existing content or create a new page. The most effective on-page SEO tips that you should use to target keyword clustering are place the primary keyword in the URL slug, H1, meta title, and description, and in the first paragraph of body content.

Plus, naturally integrate primary and secondary keywords across the content. Place secondary keywords in H2s appropriately (if possible) and consider internal linking to related pages.
