Choosing irrelevant or incorrect keywords can result in a complete waste of precious time and investment.

If you are a novice in the world of SEO, you are likely trying to figure out the meaning of keyword research and its importance. This article will help you immensely.

Without further ado, let’s get started.


What is Keyword Research?

Keyword research is concerned with identifying relevant search queries that your target customers enter into a search box in search engines when finding services, items, information, and products.


The Importance of Keyword Research

As mentioned earlier, if your web page has a topic nobody searches for online, it will get zero traffic from Google.

This is an error that a lot of site owners make, making it responsible for nearly 90% of web pages online receiving little or no traffic from Google, as a new study has shown.


Why is Keyword Research Important for SEO?

With areas like backlinks and core web vitals increasingly the focus of site optimization, a lot of people neglect how important keyword research is to SEO.

In this section, we will explain why keyword research should be key to your content creation or SEO campaign.


Discover What People Search for Online

As a content creator, an easy way to know what users are looking for online is through keyword research.

This is key because it assists you in determining quickly if you should invest time and resources in a topic or idea.

Most importantly, your content creation strategy should revolve around targeting keywords people use to search for information.

It is a waste of time to create content based on a “guess” or “assumption” of the search behavior of your target audience.


Gain Insight into the Competitive Landscape

Through keyword research, you can learn about the competitive landscape by gaining insight into your competitors.

For example, if you have a topic or idea you wish to create content about.

Keyword research will give you access to which domain is already ranking for that specific keyword.

Furthermore, keyword research gives you information that will help you decide if it is difficult or easy to rank on the first page of search engine results pages.


Discover Low Competition Keywords

Keyword research helps you uncover low-competitive keywords and content opportunities.

By doing this, you’ll improve the chances of your page driving more organic traffic and visitors via search engines.

As a new site owner, keyword research will help you determine which keywords are not worth your efforts because high-authority domains already rank for them.

Today, there are a lot of keyword tools that can help you identify low-competition keywords and filter the ones that are very competitive.


Learn More about Search Intent

Google has explained that its main mission is to organize information from around the world and make it available and helpful for anyone who needs it.

This is why Google delivers highly relevant results each time someone searches on their platform. To improve your site’s performance on Google search results pages, your content has to be relevant to the user’s search intent.

This is why you have to figure out the search intent for keywords. You would want your content to meet the user’s goal of utilizing a particular keyword to search for information.

Keyword research assists in learning about the search intent behind a target keyword.

Through the search results that come up as a target keyword, you will have an idea of the results Google believes to be highly relevant to that search query.

For instance, if you are planning content for the key phrase “digital marketing tools“, you can perform a search on this on Google to see which domains are ranking for it and learn about the search intent.
