Keyword research is at the core of any effective SEO plan. If you’re looking for organic traffic that’s relevant to your audience, you need to conduct keyword research. To achieve this, you will need to use the top free keyword generator tools available.

There are a lot of free keyword generators out there, but most of them are pretty basic unless you want to pay for the premium version. To do this, we looked through hundreds of keyword tools and tried them out to provide you with a list of some of the best free keyword tools.

Keyword Generator Tools

WPBeginner’s Free Keyword Generator

Not only does WPBeginner’s Free Keyword Generator give you tons of ideas, but it’s also free with no limits. This is a rarity in the world of free keyword generators, where you have to pay to continue using them once you hit a certain limit.

In addition, it is easy to use, it creates a large index of keywords, and it organizes them in useful ways. When you type in a keyword to search for, you will be presented with results in 3 parts: alphabetically, by prepositions, and by questions.

You can also download a table of all your results.

Preposition Keyword Suggestions will contain prepositions such as with, for, in, can, and to. Question Suggestions all begin with question words such as is, are, what, and how.

ChatGPT 

Whether you’re looking for a keyword research tool, a blog topic research tool, or any other marketing tactic, the use of AI tools is on the increase. And for good reason. AI can quickly provide you with answers and ideas on almost any topic.

When searching for keywords in ChatGPT or with your chosen AI, what is useful is to ask it to analyze keyword ideas based on the user’s personality, the target audience, or even long-tail versus short-tail.

Semrush

Even though Semrush is only available as a free version, we still included it at number 3 on our list due to its robustness. Simply plug in any keyword and you’ll get the search volume, the difficulty of ranking for it, and more.

Another great keyword generator tool is Semrush. After you enter your keyword, Semrush will provide you with variations, questions, and related keywords along with their search volume.

Alternatively, you can use the Keyword Magic Tool. This tool will take your keyword and find all the keywords related to it.

Google

Did you know you can use keyword generator tools like Google? You can get keyword ideas directly from the place you want to rank.

The first step is to use the auto-complete function to see which topics and keywords are trending for your topic. All you have to do is type and watch as Google predicts what you’ll type.

In the second step, expand a couple of questions in the “People also Ask” dropdowns after performing a keyword phrase search. The more questions you expand, the more populate. You’ll often find a few keyword and topic suggestions here!

For some queries, you’ll also see a more recent set of results called “Things to Know.” You can expand your answers and click on the “More” button to collect suggestions from there.

Ahrefs Free Keyword Generator

Another great keyword research tool is Ahrefs’ Free Keyword Generator. The free version has a limited number of keywords and 50 questions, but you can get 100 keywords for every term you enter.

One of the unique features of Ahrefs is that it allows you to search across multiple platforms in the same tool. For example, you can search for keywords on Google and Bing, as well as YouTube and Amazon.

In addition, you will also receive data on the number of searches for each keyword in the tool, even if you use the free version. If you’re ready to invest in a top-notch SEO tool and get complete access to the free keyword generator, we highly recommend Ahrefs!

WordStream

WordStream is another widely used free keyword engine that will help you decide which keywords and topics to include on your website. What makes this one unique is that you can add a URL to get suggestions based on their usage.

While the results are mainly based on Google Ads bids and competition information, you’ll also see the monthly search activity for each keyword. It’s a great way to get an idea of what your competition is ranking for and what they’re using on their sites.

Ryan Robinson’s Free Keyword Research Tool

One of our favorite features of Ryan Robinson’s free keyword research tool is that you can switch between Explorer and Ideas. To get ideas from a list, type a keyword. Or, switch to the Ideas column and get ideas from prepositions and query words.

The toggle feature is nice, but the downside is that you can’t export the data and save it to a spreadsheet.

Keyword Surfer

Keyword surfers are free Google Chrome extensions that let you see keyword suggestions right in your search engine results pages (SERPs). Once the tool is set up, it will display the suggested keywords in a pop-up window on the right-hand side of your SERP.

It displays related keywords, how often they match the original query, how often they overlap (how many search results match the original query), and how often they are searched.

With Keyword Surfer, you can add valuable information about the ranking pages to your search results, and discover new keyword opportunities in real-time based on your query.

QuestionDB

QuestionDB is a search engine that looks at the questions that are asked on popular forums such as Reddit, Stack Exchange, etc. It looks at the keywords that are asked in these forums.

You may gain more precise insight into what your audience is truly interested in knowing thanks to its extensive question bank. 

You can use this knowledge to produce better content that responds to these questions. First, create a list of relevant seed keywords. Next, type one of those keywords into QuestionDB.
