Keywords are important for
ranking and managing keywords for one or two pages is easy. But, what will you
do when faced with thousands of related keywords? How do you avoid keyword

This is where keyword clustering comes in play.
Keyword clustering is grouping
your content into related clusters or groups. Once you’ve done that you can
start writing content and have better chances of ranking in your niche.
There are dozens of free and paid keyword clustering tools
available today. In this article we will review some of them.
What is keyword clustering?
Keyword clustering is a process of grouping related keywords into clusters or groups based on their semantic relevance and similarity. This technique is commonly used in search engine optimization (SEO) to improve the organization and structure of website content, as well as to identify opportunities for targeting specific search queries.
By grouping similar keywords together, website owners can create more focused and targeted content. This can improve their search engine rankings and drive more traffic to their site. Keyword clustering can also help identify gaps in content coverage and provide insights into user intent and behavior.
The keyword “Digital marketing plan”, and “Digital marketing strategy”, are grouped together under the cluster “Digital marketing channels”, and another cluster “Digital marketing tools”, within the pillar topic “Digital marketing”.
Pillar topic: Digital marketing
