Ahrefs was founded by Dmitry Gerasimenko in 2011, but his work on search engines began much earlier.

5. Keyword Planner – Free Keyword Research Tool

Keyword Planner uses autocomplete application programming interfaces (APIs) to generate and provide data about long-tail keywords. This tool is not to be confused with Google’s product of the same name. So how does Keyword Planner contrast with Google’s keyword tool? Keyword Planner has two advantages over Google, according to them. In particular, it permits you to observe keywords that are distinct from those generated by Google and use the tool without registering. To utilize Keyword Planner, just pick your locale, enter up to five keywords isolated by commas and click on the amplifying glass button. You can also choose your favored search level, the higher the level, the more keywords will be created and the more time the inquiry will take.

At the point when we utilized a level one inquiry to investigate just one keyword “seo”, Keyword Planner returned an incredible 1267 suggestions, that is more than 120 pages. But the catch is that you’ll have to sign up for a Keywords Everywhere API key to see every keyword’s month to month volume, Google Ads CPC, Google Advertisements competition and the general pattern.

6. Google Trends – Free Keyword Research Tool

Although the search engine giant may not have intended for Google Trends to function as a keyword research tool, many SEO professionals use it as such. Google Trends doesn’t actually suggest keywords for you to target, unlike the tools we’ve talked about so far for keyword research. Instead, it shows how interested Google users have been in your chosen search term or topic in the past and now. For instance, we can see below that interest in the Google algorithm is at an all-time high:

Scroll down and you’ll also see interest by subregion as well as a little selection of related subjects and inquiries. Therefore, although Google Trends will not provide you with a comprehensive list of potential keywords, it will provide you with useful insights regarding a keyword or subject matter that you already know you want to target. A map of the United States to represent various subregions and a list of related topics and queries are displayed in the Google Trends interface as seen below.

7. AnswerThePublic – Question Based Keyword Tool

Examining the kinds of questions that users of search engines are asking is one of the best ways to identify the relevant keywords that you ought to concentrate on.

You don’t have to sign up for an email list or create an account; all you have to do is type in a topic, brand, or product, select your location, and click search.

Look down and you’ll see more perceptions of applicable relational words, correlations, alphabeticals and related inquiries. If you don’t like visual representations, simply click the data tab at the top of any graph to view its contents as a collection of lists. A collection of lists produced by the AnswerThePublic tool for the query “halloween”, at the page’s top by a tab titled “Data” can be seen below.

8. Wordtracker – Free Keyword Research Tool

Wordtracker is based in London and has been around for as long as Google. It was started in the late 1990s by brothers Mike and Andy Mindel. Although Wordtracker offers a variety of paid SEO-related products, its free keyword tool may be its most well-known offering. Enter a seed keyword or phrase and click Start to begin using it.

You will also have the option to select your preferred search engine and change your region on your results page, which will include a list of fifty keywords and the data that corresponds to them: Wordtracker’s free keyword research tool returned the following results for the key phrase “digital marketing”.

You will be able to unlock an unlimited number of searches by signing up for a seven-day free trial after using up your limited number of free searches. After that, the Wordtracker membership plan with the basic features will cost you $27 per month. While this is stretching the boundaries of the meaning of a free keyword research instrument, we believe it’s worth including. This is due to the fact that Wordtracker has a number of capabilities and features that Google’s Keyword Planner does not, such as:

• genuine (not grouped) keywords
• actual results
• metrics about rivals
• comparisons between search engine result pages (SERPs)
• live chat service for customers
• related and lateral search
• keywords for YouTube and Amazon
• negative keyword search

So assuming you’re searching for a keyword tool that has that multitude of highlights, Wordtracker’s free variant makes certain to satisfy temporarily and its paid version may likely be an ideal long term solution.

9. Google Keyword Planner – Free Keyword Research Tool

We would be remiss if we did not include the renowned Google Keyword Planner. It is a given that the information you get from Google Keyword Planner will be accurate and dependable because it is a tool provided by the search engine giant itself. However, there is one major limitation: You will need to sign up for a Google Ads account before you can begin using Keyword Planner. Also, to do that, you’ll have to give an email address and business site. You will be ready to go once you have created a Google Ads account.

Google Keyword Planner, like many of the other tools we’ve looked at so far, suggests new keywords and provides useful information about each one. It is one of a kind because it can even be used to make a full-fledged plan and provide bid estimates for each keyword. We can see from Google’s example that a plan includes things like the expected number of conversions, total cost, CPC, conversion rate, and more. Google Keyword Planner is an undeniably powerful tool for SEO practitioners who are running or plan to run a Google Ads campaign, even if you have to go through a few hoops to use it.

11. Keyworddit – Reddit Based Free Keyword Research Tool

If you’ve ever tried creating content for Reddit, you already know what a unique platform it is. To put it another way, SEO strategies that work well on other websites might not work at all on Reddit. That is the reason tools like Keyworddit are so important, because they are made just for Reddit, you never have to worry about whether the results will help your Reddit SEO strategy. Simply type the name of your desired subreddit into the search bar and select Get Keywords to use it.

If you work in SEO, you probably already know about Neil Patel. He created Ubersuggest, a tool that gives rankings correlations, content ideas, backlink information, and more.
