The Ultimate List of Free Keyword Research Tools

Keywords are an important part of your content marketing and SEO strategy. Using the right keywords that align to your website content to get it seen on search engines can drive leads, sales and ultimately revenue.

Despite this, new research found that only 30 percent of small companies in the U.S use SEO in their marketing. And many businesses may use keywords, but either do not use them effectively or use the wrong keywords for their audience.

This is why keyword research is crucial. It will ensure that you use keywords that will attract your audience and increase the online visibility of your brand and content. This blog will reveal a comprehensive list of keyword research tools to help you pick profitable keywords.

Why is keyword research important?

A keyword is any word or phrase that people type into a search engine to find out more about a particular topic.

Keyword research is important as it can get your brand noticed by an audience that will have an interest in your product or service. It is the process of researching and selecting words, terms and phrases users will search for when looking for the types of products or services your business offers.

Conducting keyword research helps you choose the most relevant keywords for your target audience. This then helps search engines like Google understand your web pages and serve your website as a suggestion for users searching for these specific terms.

When done right, keyword research can help you to:

• Get the right kind of visitors to your site: If you get the wrong type of visitor to your site, they are unlikely to click or become a sale. It may convert into leads, but it could be the wrong type of lead or one of low intent.
• Identify keywords with high search volume with low volume terms: Keyword research helps to identify and keep phrases that have good search volume, and disregard keywords with poor volume.
• Identify content gaps: This is more common than you might think. For example, when we design a website, it’s often a designer who leads the process, or maybe the CEO chose what content to include and where. But that’s not necessarily the content your users or potential customers are looking for so using keywords will help avoid a disconnect between your content and audience.
• Direct content creation: If you understand what keywords people search for, you can tailor content to match that search need.
• Target keywords within your reach: Make sure to target keywords that are not too competitive and realistic, based on your current SEO presence. Keyword research helps to differentiate between transactional keywords, which will be highly competitive to rank for, as well as less competitive informational keywords that may be useful for your business.

Short-tail and long-tail keywords

Keywords come in two forms: short-tail and long-tail keywords. The main difference between the two is that while short-tail keywords have more individual traffic, approximately 70% of all search traffic comes collectively from long-tail keywords.

This is because searchers tend to be more detailed with their long-tail searches, as they are looking for specific results. For example, ‘digital marketing’ would be a short-tail keyword, while ‘what is digital marketing?’ is a long-tail keyword.

How to Conduct Keyword Research

Before moving to on-page optimization, you will need to conduct keyword research by following these crucial steps:

1.   Pick a topic to research: Focus on one topic or theme at a time and think about what the webpage you want this content to feature on to look like. Think about imagery, headlines, CTAs, etc.

2.   Brainstorm keywords: You should research keywords with similar meanings around a closely related topic. Make sure to focus on quantity over quality at this stage.

3.   Review keyword value and difficulty: Gather keyword data from SEO tools to help decide how valuable the keywords are, and whether you can rank for them.

4.   Prioritize keywords: Decide which keywords are the most important and prioritize the ones you want to focus on.

5.   Choose primary, secondary, and tertiary keywords: Choose one main keyword and a few variations of the main keyword. For example, a primary keyword could be ‘content marketing?’ while a secondary keyword would be ‘how to create and distribute great content’

6.  Create cluster topics: Having more than one keyword can help you create content and topic clusters. See the example below on SEO from SEMRush.
