The Moz SEO platform includes a variety of tools for keyword research. Moz doesn’t offer as many data points as some of the other fully-featured SEO tools (such as SERP position history or the total amount of keywords a competitive result ranks for). However, without sacrificing the metrics you truly care about, it makes for a less intimidating user experience for individuals who aren’t experienced, search marketers.

You may look for any term using this free keyword research tool and check its monthly volume, difficulty, and organic clickthrough rate (CTR). From there, scroll down to obtain an analysis of its current results ranking and ideas for related keywords.

With the “Priority” score provided by Moz, you can quickly determine whether a keyword is worthwhile for you to pursue. In addition to your “My Score” — a measure you select yourself, marking how significant a certain term is to your business, based on your own expertise and knowledge of your business and industry — Moz automatically calculates the score based on the phrase’s volume, organic CTR, and difficulty.

Google Keyword Planner

Google Keyword Planner is one of the best free keyword research tools available for PPC keyword research. You won’t ever have to worry about hitting restrictions or having to pay for upgrades because it’s totally free (even if you choose not to purchase Google Ads).

There are two main aspects of Google Keyword Planner: one is for exploratory keyword research and discovery, while the other is for a more thorough analysis of search volume and predictions.

Like many of the free keyword research tools on this list, the “Keyword ideas” feature searches for a seed phrase and then generates further keyword suggestions along with information on monthly search traffic, change over time, competition, ad impression share, and bid ranges. Your keyword list can be filtered by brand or generic terms, source websites, and more. The “Forecast” function, if you also use Google Ads, makes it simpler to budget and plan ahead for your paid advertisements.

By highlighting areas where ranking organically could help you save money on PPC, Keyword Planner or the google keyword research tool can also aid you with your organic strategy.


If you’re looking for a sophisticated free keyword research tool, Semrush offers a tonne of keyword data, makes it simple to delve into the specifics, and offers granular analysis of recent results in addition to SERP elements like featured snippets, reviews, site connections, and picture packs. Additionally, Semrush provides a wide range of free keyword research tools, including content-driven keyword research, competitive keyword gap analysis, and standard traffic and search volume metrics.

Semrush stands out for its wide range of tools, which include the standard Keyword Overview, the Keyword Magic Tool for experimenting with keywords, a Keyword Manager and position tracking feature, competitive Keyword Gap analysis, and Organic Traffic Insights, which, when integrated with your Google Analytics or Search Console account, can reveal those notoriously difficult “not provided” keywords.

The SEO Content Template tool is an added bonus of this free keyword research tool because it enables you to automatically create a content brief and optimize content as you write by grading your content in real-time for readability, originality, tone of voice, and SEO. It does this by using a helpful bullseye graphic to help you strike the right balance. Additionally, the tool graphically verifies SEO tips as you go, such as adding pertinent links and images and using your goal and associated keywords.

Keyword Surfer

Keyword Surfer is a free keyword research tool that provides an easy approach to conducting keyword research without ever leaving the search engine results page through browser extensions. Surfer SEO’s Keyword Surfer add-on for Google Chrome provides a free, restricted version of the platform separate from the whole SEO package.

As you enter, you’ll see predicted search volume and CPC data appear in the search box. Entering will display the same information together with the number of exact match keywords used on the page for each SERP listing.
