15 Free Keyword Research Tools for Serious Marketers Only

Targeting the wrong keyword is like shooting an arrow in the dark.

In fact:

80% of online businesses fail just because of wrong keyword selection or no keywords at all.

This is why keyword research is important for the success of any online business.

A study found, 82.6% of internet users start their searches with keywords in the search engines to find the product or services they need.

What is the keyword?

Keywords are the words or phrases that people enter into the search engine to find the solutions of the problem they have.

Keyword research is the initial step of a comprehensive SEO strategy. Furthermore, it is also a foundation of the search engine optimization process.

You might don’t know, but 75% of users never scroll past the first page of search results, that means you have to be in the top 10 results of the search engine to get traffic to your website.

However, getting on the top in SERP depends on various other factors such as off-page and on-page SEO, etc.

But…keyword research is the major one and you must know how to find the right keywords that your targeted audience searches.

…and most importantly you must have the right keyword research tools to find those keywords.

Keep that in mind, I’ve compiled some of the best free keyword research tools that will help you do keyword research like a pro in few minutes. Here we go:

#5. Google Search Related To

Google is getting smarter day-by-day. Sometimes I feel Google reads my mind. It automatically detects the context of my query and shows me the results accordingly.

Additionally, it even shows the related keywords that people search for.

I use those suggested terms as LSI (Latent Semantic Indexing) keywords in my content to avoid keyword stuffing.

It’s very easy to find LSI keyword ideas from Google Autosuggestion. All you need to follow three simple steps like this:

  • Search your main keyword in Google.com
  • Go the bottom of the search results and you’ll see “Searches related to.”
  • Note down those phrases and use them as your keywords.

#6. Forums and Discussions

A good keyword research best practice is when you get inside of your prospect’s mind and know what words and phrases they are using to find your product and services.

…and to do that nothing could be better than forums.

Forums are the places where people speak out their mind and discuss the problems that they are facing.

In other words, forums are gold mines to find the untapped keyword ideas. Let me show you how to get the best keywords from the forums websites:

  • Find out few popular forums in your niche.
    Type “Keyword” + “Forum” or Keyword + Discussion

I searched for “Women Fashion” + “Forum”.

  • I opened bellaonline.com from the search results.

Women Fashion BellaOnline Forums

  • See here I found some untapped keyword ideas that most people are showing their interest to talk about. That means if I use these phrases in my content I might hit that targeted audience that my competitor might be missing.

#7. Google Trends:

There is no benefit of using the keywords that no one has interest now.

The question is, how would you know that?

Google Trends.

Yes, this is the best tool to know how keywords perform over time.

Google trends give you insights about the keywords you are using to know if people still have their interest in those keywords or not.

Here is how to use Google Trends as a keyword suggestion tool:

  • Open Google Trends.
  • Type the keyword related to your niche in the ‘explore topic’ box and then select the targeted country.
  • The tool will show you a graph representing the interest of the people over time.

By following the above three steps you could know the potential of the keywords before creating any types of content.

  • Scroll down towards ‘related searches’ section and choose the relevant keywords from the list. These keywords are the terms which are related to your services and people also use them while searching on Google.

#8. Google’s Search Console:

I know what are you thinking? Google’s Search Console is not a keyword research tool.

I agree. I’m not denying it.

But you might don’t know that it is a hidden treasure of good keyword ideas.

Let me tell you how you can pick some good keywords from this tool within few seconds:

  • Sign-in to Google Search Console
  • Open the dashboard of the web property for which you want to do keyword research.
  • Go to the ‘Search Analytics’ section of under ‘Search Analytics’ section.

Search Console Search Analytics

  • Pick-up the best suitable keywords for you. Like I did in the following:

Now, what would you say?

Isn’t the tool is a genius? Yes, it is.

#9. Quora.com

Quora.com is a popular platform where people share their real life problems and look for the solutions.

As an expert, it’s your job to provide them the solution consider their problems as your keywords and create content around that.

How it’s going to help you?

Because they’ll also look for the answer on Google.com.

#10. Google’s Suggestions

Google suggest is also known as Google Autocomplete. Google always suggests keywords based on user’s search behavior. For example, if I search for best coffee it automatically suggests some relevant keywords like best coffee in the world, best coffee, best coffee maker, best coffee in India.

Google-auto suggest

These are the LSI keywords which people usually search on Google. You may use them in your content because people are already looking for them.

Google Suggest is one of the best ways to find LSI keywords.

#11. Ferzy – Keyword Difficulty Checker

Ferzy is a new and not so popular keyword research tool – but it’s really useful. And the reason is, it shows numerous good quality keywords with difficulty score.

Difficulty score basically is a metric that shows how difficult your keyword is to rank on the search engines compared to your competition.

You may see top ten results from the Google along with the domain age. It is one of the best keyword research tools I’ve ever seen. However, with a free plan it allows only 10 searches in 24 hours but that is enough.

#12. Amazon

Amazon is the biggest online marketplace having more than 398,040,250 products. In fact, 40% online shoppers start their product hunt by Amazon instead of a search engine.

It’s not just an e-commerce portal but also a search engine that gives you amazing untapped keyword ideas especially if you’re running an e-commerce website.

Here is the good news:

Yoast has developed a tool name “Yoast Google Suggest Expander” that can help you to avoid it. Using this amazing tool you can have many unique long tail keywords with just one click.

Let’s look at the steps to use it:

#14. LSI Graph

It is the best tool to find LSI keywords. LSI stands for latent semantic Indexing.

It is an indexing system used by most of the search engines to show the related keywords based on the user’s search behavior.

I recommend this tool to find the most proficient long tail keywords.

If you are not sprinkling LSI keywords along with your main keyword then you are missing opportunities to get higher ranking on Google and other search engines.

LSI keywords are the key to get higher ranking engines. Using this amazing tool is uncomplicated.

Keyword Shitter is also a handy tool when it comes to finding unique long tail keywords ideas.

If you want to find a long tail keyword including or excluding a particular word then it is a useful keyword finder tool for you.

Let me show you how to use this awesome tool with an example,

I searched for ‘DIY greeting card’ and it started shitting some long tail keywords. I paused it by hitting stop the job button when I felt that I got enough keywords. You may find the suggested keywords below.

Keyword Shitter The Bulk Keyword Tool

Now, I thought I don’t need occasional keywords with organizer word in them. So, I added ‘organizer’ word in the negative filter box.

Keyword Shitter The Bulk Keyword Tool-negative keyword

It filtered 91 out of 94 keywords.

Now, I want to filter the keywords for a different occasion or different people, so I filtered out those which are having ‘for’ word.

  5. Keywords are one of the most important and essential parts of SEO. The keywords you pick to focus on for your search engine optimization (SEO) efforts are necessary to the achievement of your website’s rank. As compared with Basic Keyword Research; personally I spot out the Competitor based Keyword research to be more productive as the best option for the Keyword research is to get high paying Keywords. What could be more valuable than something which is working for someone already; exactly that you need to find out with these tools. All you require to do after that is to build a page targeting selected profitable keyword & get the advantage of keyword research.

    I am working with Google keyword planner the best keyword researcher tool till date. This always will be my prime preference because it’s simple to use and of course it’s free. On the Google KWP tool, I have used a plan and got success. I have used my competitor site as a landing page and examined targeted keywords. This provides me such great results that I don’t get to my own landing page. That’s why Google Keyword Planner is proven as one of the best tools for keyword research purpose, and it’s built with many more features. The Keyword research is one of the most important factors for SEO. Ranking for the right keywords can create or destroy your website.

    Other tools by SEMRUSH or Ahrefs are also useful; it gives all the details about you keyword like competition, search volume, the number of backlinks require to get the first page of Google.

    Google keyword is still the best keyword research tool as it takes nothing. It is entirely a free tool with excellent results. So, I would like to suggest Google keyword planner for use.
