8 free keyword research tools for SEO (that beat their paid alternatives)

You are here:

If you Google for a list of SEO tools, you’ll see there are almost 200 options on the market now.

All of them differ in features, amounts and sources of data, and, definitely, prices. But which of them do you really need? And, most importantly, do you have to fork out hundreds of dollars a month, or is there a way to cut the costs?

Today we’ll explore 8 of the best free keyword research tools. Each of them best fits a specific keyword research task and does the job no worse than their paid alternatives.

1. Rank Tracker

To find the most ample list of keyword variations and analyze their SEO profitability.

When to use:

Your best SEO keywords are often not the most obvious ones. To find real keyword gems, you need to dig out all the possible variations from multiple data sources.

And this is where Rank Tracker comes in especially handy with 23 different keyword research tools inside it:

Suggestions from Google, Bing, Yahoo, and Amazon;
Google Ads Keyword Planner and Google Search Console integration;
Database of all SEO keywords your competitors rank for;
Long-tail keyword and question generator;
Popular misspellings and permutations;
And more.

Using the tools one by one, you get the most ample list of keyword ideas. More to that, you can analyze the keywords’ traffic potential and check how fierce their SEO competition is. This lets you focus the SEO efforts on what takes the least effort to bring in the most traffic.

Free version:

Even though the tool has a more feature-rich paid version, the 100%-free version is absolutely enough for keyword research. It lets you use all the research tools and analyze the keywords’ traffic potential.

2. Google Search Console

To discover “low-hanging fruit” traffic growth opportunities for your current keywords.

When to use:

Google Search Console is the place to analyze your current SEO keywords with their average Google positions, impressions and CTRs.

Looking through this data is a great way to find unexpected SEO shortcuts. For example, if your URL currently ranks on page two or three, Google already considers it pretty relevant for the keyword. And the URL might need just a little SEO boost to storm onto page one and start bringing you a lot more traffic.

Or you might notice that some of your page-one ranking keywords underperform in terms of clicks (have low CTRs). A little tweaking of their SERP snippets or adding the Schema markup could work wonders here.

Free version:

Google Search Console is free to use.

3. Google Ads Keyword Planner

To decide which keywords to target with SEO and PPC.

When to use:

For some keywords, low ad bids make it reasonable to simply purchase keyword clicks with PPC. For others, overly expensive clicks mean you need to win over the traffic with SEO.

So, before starting out any search engine marketing campaign, you need to split your keyword list between SEO and PPC targeting. And the best place to look for the needed data is, obviously, Google Ads Keyword Planner.

The tools shows you search volumes, cost-per-click data, advertiser competition and seasonal traffic fluctuations, all in one place. And it even lets you estimate the prospective PPC spends in your niche.

Free version:

The tool is a free one. However, keep in mind that unless you are already spending enough money in Google Ads campaigns, your search volume analysis is limited to ranges (rather than exact search volumes). And you might need another tool (like Rank Tracker) for more precise search volume analytics.

4. AnswerThePublic

To find popular questions for featured answers and voice search optimization.

When to use:

With Google’s ability to better understand natural language, searchers got used to phrasing their queries as questions rather than separate words. And with the rise of voice search, the trend got even further.

Making your content answer exact searcher’s questions is one of the key aspects of your voice search success. Plus, question based content has a bigger chance of squeezing into Google’s featured answers or the so-called “position 0” results.

The quickest and easiest way to find popular questions related to your business niche is AnswerThePublic – a no-brainer tool that combines your main keywords with various question words (like who, what, why, etc.).

Along with questions, you will also get a handful of “preposition” keywords (when your seed keyword is combined with another word via a preposition) and “comparisons” (like “your keyword vs another keyword”).

Free version:

AnswerThePublic is free to use.

5. Keyword Tool Dominator

To find keywords from Amazon, Etsy and Ebay.

When to use:

The way your customers search Google differs from the way they search Amazon. In fact, they Google for places to shop at, and search Amazon for the goods they shop for.

So, for you as an Amazon vendor, it isn’t going to be quite enough to simply research SEO keywords for Google. You need to have your listing optimized for Amazon search and Amazon keywords just as well.

A nice tool to dig through the Amazon database is Keyword Tool Dominator. The only thing to keep in mind is that there’s no way to check Amazon’s search volumes. What you get is a plain keyword ideas list.

Free version:

Without a paid license, you can only make three requests to each of the databases (eBay, Amazon, Etsy) a day.

6. Google Trends

To find the right keywords for your local business.

When to use:

Quite obviously, user search patterns differ between countries. But, more surprisingly, the trends also vary considerably from region to region.

Google Trends is here to help you identify city/location specific search volume variation. Just have the tool compare two synonymic queries to see how misleading a country level keyword analysis could be for a local biz.

For instance, according to Google Trends, even though “personal injury lawyer” is the most popular search request throughout most of the US states, in Tennessee and New Mexico you’re way better off when optimizing for “personal injury attorney”.

Another no less important use-case is tracking down your keywords’ seasonal fluctuation and being able to reliably predict how this or that keyword is going to perform in it’s high and low seasons.

Free version:

Google Trends is free to use.

7. Google Correlate

To pull unexpected keyword ideas from adjacent niches.

When to use:

When thinking of seed keywords for your business, most probably you’ve already listed the most obvious ideas. Say, it comes as no surprise you flower delivery shop should target all kinds of “local florist” and “roses delivery” variations.

But Google Correlate helps you look at your keyword list at a new, unexpected angle, identifying the words, whose seasonal interest fluctuations correlate with that of your main keywords.

For the flower delivery example, our main keywords are in correlation with other female present delivery services: chocolate delivery, dipped strawberries and so on. And even if those have nothing to do with your biz, you can probably utilize them in content targeting for holidays like St. Valentine’s Day.

Free version:

Google Correlate is free to use.

8. Keywords Everywhere

To analyze keywords while you’re browsing.

When to use:

Keywords Everywhere is a free browser add-on, which lets you analyze keywords while simply browsing Google, Bing, YouTube and other websites.

Whenever you start typing into the search box, search volumes are added to all the keywords you see in Autocomplete suggestions. On the SERPs themselves, a box with new keyword ideas is embedded on the right-hand side of the page, so that you can fill in your keyword list without actually leaving Google.

Free version:

Keywords Everywhere is free to use.
