Are you looking for alternatives to a keyword research tool you are currently using? Then look no further cos you will be presented with the list of tools to help you scale your SEO keyword research.

Keyword research has always been the secret of gaining organic traffic. Without it, your content will be difficult to find organically. So, right in this article, I will give a brief description of 6 essential free tools and 5 paid tools.

For the purpose of those who are new to Search Engine Optimisation, let me start by stating the meaning and the importance of keyword research.

What is keyword research?

Keyword research is a systematic process of gathering data regarding words and phrases that are commonly searched for by web users on search engine platforms. Usually, professional web writers create contents using these search terms in order to target a specific audience.

To uncover these search terms, you have to use any of the keyword research tools. Following this systematic process can increase your website ranking, thereby leading to an increase in organic traffic.

Why is keyword research important?

As most online marketers know, the most critical part of SEO is to do keyword research. Writing web contents without considering search terms beforehand may never get your contents in front of your audience. So, to get your target audience to see your contents, you need to perform keyword research.

Another good reason to research the key terms before writing is to give you an edge over your competitors. That means, find out what your potential clients or customers are searching for, and build your blogs, videos or podcast around those search terms.

In case you are a newcomer into a highly competitive market, using low competitive keywords to gather your audience is the best way to start. And doing keyword research will show you those low competitive terms.

Best free keyword research tools

Here are lists of free tools in case you are not yet able to get a premium version. The downside to some of these free tools is their limitations. However, there is still a lot to get from using the combination of various tools to achieve your goal.

If you cannot get everything you need with the free tools, try out the paid ones and see how they work for you. It’s all about trying each one to figure out which suits you best.

1. Google Keyword Planner

6. Soovle

One of the easiest ways to find a keyword or phrase is to use Soovle. It provides keyword suggestions from different search engines then combines the result into a single platform.
