Keywords are powerful when it comes to website optimization. With the right content, user experience, and other factors, they can bring your pages to the first places in Google SERPs. But what if you have a large website and there are thousands of them, at least several for each page?
You have to group them somehow, right? Otherwise, it’s a pain to go through the list, trying to find similar keywords for one page.
If only there was some kind of keyword grouper or something.
And the digital market has some excellent keyword clustering tools to offer that will make it much easier to navigate your database. In this article, we present the 5 best options with reviews, pricing, pros, and cons.
What Is Keyword Clustering?
Keyword clustering or grouping is a method of query organization that helps SEO specialists and content marketers navigate a large list of keywords and their data. Clustering tools offer to categorize the list based on search intent. Doing so manually would take way too much time, and digital algorithms are often better at it.
As a result, you can insert target queries with the same search intent into one or two blog posts, for example, increasing the chances for a higher ranking and driving high-quality targeted traffic to the pages.
Grouping also helps with building a content structure as you can see the number and diversity of the queries on the list, deciding how many pieces of content are needed to avoid keyword cannibalization.
Linking groups will also help you organize the internal link-building process, encouraging people to read more on your website and spend more time on it. This also helps search engines to crawl your website faster and more effectively.
Basically, you can do it yourself. Just export the lists of keywords from the SEO tool of your choice into an Excel file and categorize them by search intent, topic, etc. But imagine how much time you will waste.
It’s much better to use a tool that will do the job in much less time and without your interference.
Why Is Keyword Clustering Important?
These days, if you don’t use automation, you’re keeping your project behind. Using tools for automation of routine, repetitive processes helps you save time you can put into content writing, keyword research, competitor research, external link building, and much more.
Why not use a digital helping hand?
Besides, as machine learning becomes increasingly popular and useful, it’s only fair to trust an algorithm or AI (artificial intelligence) to do the categorization for your convenience.
More than that, SEO moves forward from the idea of focusing one page on one keyword. You can rank for hundreds and even thousands of queries with that one page. So, seeing semantically similar keywords and targeting them all at once in one blog post can increase your chances to reach a higher place in SERPs and drive the right people to the site.
The tools we present below can perform keyword clustering accurately by using either live data from related SERPs or NLP (natural language processing). They are extremely useful and can level up your SEO game a lot.
