7 Top Free & Paid Tools To Do Keyword Research


Keywords remain the proverbial salt among the cooking ingredients for your website SEO. Since short search terms and keywords are only within the reach of the world's most visited web domains, it is the long-tail keyword that is still the show in the SEO world now. So, if you are a professional SEO services company, you already know the importance of keyword research tools. 

Right keywords not just boost traffic but also help generate high quality traffic with expressed intent for purchases and business conversion. But at the same time keyword research is a reasonably vast area of expertise and there are different keyword research tools to fulfil different requirements. 

Here through the length of this post, we are going to showcase some of the leading keyword research and keyword analysis tools playing different roles according to the contexts and requirements. 

Moz Keyword Explorer

Moz as the leading SEO platform provides an array of super-efficient tools for keyword analysis and research. Moz may be limited in respect of covering too many data points just like various other full-featured tools. But this simple-featured tool can actually be beneficial as it is very unlikely to overwhelm the users. At the same time, it offers pretty much all the essential metrics that users generally need. 

Thanks to the Keyword Planner tool offered by Moz, an on-page SEO expert can make a detailed analysis of various keyword options corresponding to their monthly search volume, difficulty level, organic clickthrough rate (CTR), etc.  

Moz also offers the awesome feature called "Priority" score to help you evaluate whether a keyword is really targeting. The calculation of the score is carried out by Mozo on the basis of keyword volume, difficulty level, organic CTR, and the importance of the keyword for your business.

Moz keyword research tool comes also with a free plan allowing up to 10 queries in a month. The Moz Pro starts with a $99/month plan allowing 150 keyword queries every month. Moz is also highly regarded because of its user-friendliness. 


GetKeywords is a keyword research and keyword suggestion tool focused particularly on finding the most relevant local SEO keywords for your website. The tool allows you to narrow your searches down to a particular country, state and even city. When making the search, you can automatically see the top locations within every country or state. The tool also helps you to see a complete breakdown of figures corresponding to the mobile and desktop traffic. 

The tool when scrolled down will help you see all related keyword options organised in groups based on the search intent and covers all search categories such as video search, eCommerce, and simple questions as search queries. 

But this is not all. The tool also helps you to see the average bounce rate as well as the organic click-through rate for the target pages for search engines as well. This insight will help evaluate whether the keyword is worth targeting for search rank and what are realistic goals to set for each keyword ranking.

GetKeywords tool comes with both paid and free plans. While the paid plans charge $24 per month offering a lot of additional keyword research inputs such as SEO difficulty and keywords targeted by competitors, the free version ensures basic usability quite well.  


Semrush apart from its awesome feature set covering almost every aspect of keyword research also earns the reputation of being a highly expensive tool. Business users who focus on advanced inputs corresponding to keyword research and details of keywords, always find Semrush more effective and efficient. This tool is credited to having capabilities for providing granular findings on every keyword. 

Most importantly, Semrush just doesn't offer keyword research tools just like many of the services listed here. Semrush also helps fetch standard traffic data and data corresponding to search volume. The tool also provides a detailed content-driven keyword research function as well as a competitive gap analysis among keywords. These additional features help business websites to keep a sharp eye on the keyword performance corresponding to other competitor websites. 

On top of everything, Semrush also offers an SEO Content Template tool to help optimise the content based on grades received as per content readability, originality tone of the content and SEO. As we have said, Semrush is quite expensive and the pricing starts at $119.95 per month allowing you to see 3,000 search results every day and 250 different keyword metrics every month. 

Google Keyword Planner

Google as the leading search engine also provides several great keyword research and analysis tools. The most important tool offered by Google for Keyword research and analysis is Keyword Planner. This tool is primarily focused on Google AdWords results and can be highly effective if you use AdWords for search engine campaigns. 

The tool can be used simply by making inputs with one keyword or several different keywords or just by typing your website address in the field provided by the Keyword Planner. As soon as you finish doing this, Google will come out with a big list of related keywords along with data metrics for each keyword. This will help you evaluate the potential of each keyword for using them in search engine campaigns. 

The keywords and their corresponding metrics and data points will also make you find how each keyword performs statistically. The tool will help provide a long list of competitive keyword options effective for different Google AdWords campaigns. 

Google Trends

Google Trends comes as an awesome keyword research tool from Google that allows making research on a variety of keywords and filtering them as per location, search engine exposure, category and history. After furnishing all the information, the tool will allow you to see the entire interest generated around a keyword or search term and the source of the website traffic. 

The ultimate benefit of using Google Trends is that it not only furnishes static numbers corresponding to the keyword volume as done by most keyword research tools, but the tool also shows quite interactive visual graphics showcasing the performance of different keywords and the trends. Google Trends is a more dynamic tool to offer in-depth insights on keyword finding and discovery. The best thing is, it covers the entire range of options including different spellings and misspellings of keywords. 

Keyword Generator

Keyword Generator created and maintained by Ahref is basically a keyword finder or keyword suggestion tool that can gobble up more than 150 different keyword ideas for every different keyword option. For any word you type, the tool generates hundreds of keyword options containing that particular word along with estimated search volumes for each keyword option. 

For every ten keywords making the list, it also shows the Keyword Difficulty (KD) score. The ranking difficulty is calculated by the number of backlinks you are required to rank. The tool also allows you to search different parts of the world for keyword performance and ranking. 

Keyword Sheeter

Keyword Sheeter is actually a simple tool that basically incorporates the idea of pulling thousands of Google autocomplete suggestions into one sheet for a detailed view of all the keyword options. When you want to generate several different ideas for using keywords effectively in content, this comes as the ideal tool. 

The shortcoming of the tool is that it comes as a basic keyword tool without offering much deeper insights into keyword data and research. On the other hand, it comes with a really handy feature that allows using positive and negative filters. While the positive filter finds keywords and searches terms containing a specific word, the negative filter delivers results excluding that particular word. 


So, the keyword research tools we covered here cover pretty much every kind of tool and technology to find the most relevant keyword options for every niche. Obviously, there is no better or worse among these options. The choice entirely depends upon your needs and the budget.
