Keyword research is at the core of Search Engine Optimization (SEO). It involves identifying the most commonly used words or phrases that people search for on the internet. For this reason, it gives marketers an idea of the demand for specific keywords and how competitive it is to rank for these terms on the search engine results page (SERP).

Besides how helpful it is for search engine optimization tasks, it also gives marketers better objectives on which content to make next, based on the clients’ needs. It also helps in gauging which topics are relevant in a certain time frame and the variety of words that people use for a search. There are many keyword research tools that can help you do all this.

Even if you have a great website with great content, if you do not perform keyword research, you’ve wasted your hard work by losing your potential traffic. Trends come and go, so you need to stay updated to produce timely content and rank better on organic search results.

If you cannot afford paid keyword research tools like Ahrefs Keyword Explorer, Jaaxy, or KWFinder, etc., don’t worry. Here are some free keyword research tools to bring your SEO game up:

Google Keyword Planner

The Google Keyword Planner is the most popular and widely used keyword research tool and has been from the very beginning. It is very functional and easy to understand. You can use it to find new keywords and get the search volume data. It is very accessible and has a direct link to Google, which is the most used search engine on the web. It is the perfect choice for optimization when you are starting a new website.

When you want to explore more keyword ideas, enter your “seed,” or the main keyword for your topic, and Google will provide hundreds of options for you. You can also find the average monthly searches, how high the competition is, and the top of the page bidding for these terms. With this keyword research tool, you can have the option to enter a URL, or both the URL and the seed keywords. Compared to other keyword research tools, Keyword Planner provides fewer related keywords.

Keyword Planner also gives you information on the historical metrics for your chosen keywords. You can use it to see how many impressions you could get, the click-through rate (CTR), and the cost per click (CPC) for when you decide to run ads for that specific keyword. Unlike the way it was before, Google already restricted the data to a range of monthly searches rather than the actual number of searches.

Wordstream Keyword Tool

Like Google Keyword Planner, Wordstream’s keyword research tool gives you a list of related keywords from your niche (a group of words based on your seed) and gives you the option to categorize them based on their industry or theme. You can also choose which country you want to derive the results from. It provides the Google search volume, competition, CPC, and the opportunity score for ranking.

You get a 7-day free trial for Wordstream and 30 free searches. Then, you need to subscribe to Wordstream Advisor for more access and use your searches wisely!

Answer the Public

Answer the Public makes a search cloud with the data of related searches from your seed keyword. You may also read the values through the “Data” tab if you don’t want the visual cloud.

This keyword research tool is a straightforward tool for categorizing queries from search engines. You get to see the most popular searches for the 6Ws and are, how, will, and can questions. They also have an area for prepositions and comparisons as well as a section with alphabetically arranged queries after the seed word. But, unlike the other keyword research tools, Answer the Public does not show search volumes, CTR, CPC, and impressions.

Google Trends

Google Trends is beneficial for producing content on your website according to your audience’s interests. While Google Keyword Planner shows the exact values, Trends provide the relative search popularity of the keyword for your chosen time frame.

Create your content calendar after studying your topics on Google Trends to avoid producing material that is no longer relevant. Use this keyword research tool to check for seasonal trends, and compare changes over a period of time for two keywords.

If you only look at search volumes, you may see that one keyword generates a higher search volume than the other. But when you look closely, you might notice that the term with the more significant number of search volume was popular at a specific period but is declining, while the other keyword is increasing. This result happens because the rank is of their average score for a year or more.

Besides comparing keyword popularity, Google Trend could also provide you related searches and which regions or countries these searches are coming from.

Soovle

Soovle is probably the simplest keyword generator on this list. It uses autocomplete to generate popular keywords from a variety of websites such as Google, YouTube, Amazon, and Yahoo and all in one site. In this way, you don’t have to look through every website to see correlated phrases to your main keyword.

Soovle also showcases the Top Internet Keywords of the day in an alphabetical list and shows which websites they’re trending in. Though it does not show the search volume and other data of these terms, you can drag-and-drop suggested terms to save them and then download them in a CSV file for future use.

Ubersuggest

If you’re looking for keyword research tools that provide search volumes, historical metrics, and idea suggestions, you may want to check out Ubersuggest for a more extensive keyword variation. Ubersuggest gives almost unlimited results based on your main keyword. It is a useful keyword research tool to generate fresh ideas for long-tail keywords and blog article topics.

Ubersuggest is an extremely comprehensive tool. It can load you with the data you need for enhancing your SEO.

After a look at the overview page, you will see the search volume, the SEO difficulty, the estimated competition in the paid search, and the cost per click. You also get to see a graph of the historical keyword data from the mobile and desktop searches, the click-through and no-click rates, and the searcher’s age range.

Right below this information is a detailed summary of suggested and related keyword ideas and those that are questions, with prepositions and comparisons. It shows the trend, volume of searches for the month, CPC, paid difficulty, and SEO difficulty. They also give content ideas for content marketers with links related to the keyword while showing estimated traffic from Google and impressions from Facebook and Pinterest.

Ubersuggest has a traffic analyzer and an SEO analyzer that audits your site. With Ubersuggest’s newest feature, you could type in your competitor’s domain to give you better keyword ideas.

Wordtracker Scout

This keyword research tool’s best features are that it analyzes what the competitors are doing, can access the performance metrics of high-level keywords, and the simplicity of usage makes it easy to understand.

The information about your competitors’ activities can be your benchmarking strategy making it beneficial when you are launching a new site. It can reveal how they have managed to be on top of search engines, or how they were able to pull traffic to their website.

It is not a guarantee that when you have the right keywords, you can surpass your competitors or be equal with them. But, this free Chrome Extension can give you confidence that, when using the ample data you have collected, you can analyze target keywords and use them to your advantage.

Keyword research is the backbone of SEO, but you should carefully study how to do this task properly so you can avoid analyzing the data and responding to it the wrong way.
