You mustn’t just get the first free tool that you come across. Find a combination of professional and experienced tools that will help you increase your SERP (search engine results page) rankings and effectively drive higher-quality traffic to your website.

We have reviewed dozens of the most popular free SEO keyword research tools currently available on our list of the top 7 peaks. Use them to find out what your target audience is looking for and select the best words for your brand.

1: Google Trends

The best free keyword research tool

While Google offers its keyword suggestion tool for Google Ads PPC campaigns, it may be the most valuable keyword tool in Google Trends. This is especially true because the Internet is an ever-changing and evolving medium, and identifying simple patterns in search behavior can lead to long-term competitive advantage.

This is an example; even under normal circumstances, celebrity announcements, new product releases, and consumer behavior changes (often caused by new technologies) mean that identifying such trends can be valuable.

Google Trends offers the largest window of this, allowing users to search for specific keywords and identify trends related to them and openly delivering current trends and key indicators. This will enable the correct direction for keyword information.

For example, a sudden increase in search engine traffic can cause a specific marketing channel, not just SEO. This happened in Corona’s case virus pandemic when working from home led to an increase in a wide range of search terms with remote work software and from home equipment such as laptops.

Google Trends is undoubtedly one of the best free SEO keyword research tools because of its highly visual nature, which ranks first. Enter your keyword phrase in the search bar, and it will display a graph showing how the search trend has been adapted.

Other prominent features of Google Trends include:

Interest by subregion: 

This section allows you to see the places where your search keyword was most popular at a particular time.

Related Topics & Questions: 

This miracle box shows you the popularity of search terms, which you can also include in your content.

With Google Trends, you can make it an ideal service for seasonal businesses; Keep in mind that terms that extend the search volume for a certain period will also increase your Adwords costs per click. If you are looking to get paid search marketing campaigns at peak times, you will need to spend more on your Adwords.

2: Google Correlate

Of course, Google Correlate is technically part of Google Trends. However, as these two tools are fundamentally different, Google Correlate deserves its mention.

In principle, instead of searching for keyword trends, Google Correlate finds search patterns that are relevant in the real world.

For example, when I look at the term “why freelancing,” the correct term is “freelancing.” The graph below shows the popularity of both terms in different periods.

The best thing about Google Correlate is that it helps to understand the various questions people have.

The worst thing about Google Correlate? Sometimes, you get irrelevant words or phrases that have nothing to do with your chosen topic. When this happens, it is best to avoid these words to make sure your content is original and authentic to the reader.

 3: AdWord & SEO Keyword Permission Generator

If you are creating a new website, then you may already know the keywords in your niche. But where do you go from there?

Yes, a little thought, but this free tool can help you get creative if you are looking for relevant terms to your industry, marketing strategy, and target audience.

Keyword Tip: Be the foremost generator of your search terms. Choose a word association game with your chosen keyword (s) – Awesome how many people you can generate when you pay attention to it! Try to create related terms and ideas before using a keyword research tool.

While this tool is beautiful and fast, the downside is that some of the results make no sense. You often have to invest in energy to get good things done.

 4: Ubersuggest

With the idea of ​​B2B Marketing Extraordinary Neil Patel, Ubersuggest is a great alternative to Google’s original keyword builder (which you now need to sign in and create an ad campaign to use the service).

The main pro of this tool is that it sorts the terms according to several relevant metrics:

Volume: Number of searches per month

Cost-Per-Click (CPC): Average CPC by Adwords

Paid Difficulty: Estimated Competition in Paid Search

SEO Difficulty: Probable competition in organic search

Keyword Tip: Sometimes, it is best to avoid the most competitive search terms. Instead, consider one of the most popular options, which does not stand out in exceptionally high cost or SEO complexity. This way, you will likely get to the search engine results pages (SERPs).

There will also be a small box of Neil Patel itself, which informs you how easy it is to sort your search term, as well as a convenient schedule that shows the search volume per month.

With this incredibly handy tool, you can also quickly create a list of additional ideas, including ideas for suggested and related search terms.

Be that as it may, Ubersuggest’s main problem is that it offers keywords that are not distinguished by Google Keyword Planner. ნიშნავს means this does not work as an independent option. Instead, it’s a good idea to use Ubersuggest, another keyword research tool, for maximum success.


 5: Keyword Shitter

Although a little inappropriately named, this top keyword research tool works using Google Autocomplete – meaning, results that appear to be entered in a search engine. While there are other tools to do this, most are limited to 700 keywords, and the keyword is not Shitter.

Just enter your keyword and click “Close”! The tool will create a multitude of suggested search terms.

For example, when I was looking for “dark chocolate,” more than 500 results were found in a few seconds, and this tool continued again!

While the keyword Shitter gives you plenty of options, it’s pretty basic. They say they have the following handy filters:

Positive Filter Write the word you want to see in your results in this box.

Negative Filter Write the word you want to exclude from your results in this box.

Once you get enough results for the job, just click “Stop Job.” Then, the only issue is to develop hundreds of options to find the one that best suits your needs.

6: Keywords everywhere

Keywords Everywhere is a free extension for Google Chrome. It gives you search volume, competition data, and per click on your web pages.

This tool will be very handy from Google to Amazon and Wikipedia when it comes to incorporating keyword research into your regular browsing habits. The plus is that this way you can find endless possibilities.

Note that keyword volume and Cost Per Click estimates are removed from search terms by Google and not Amazon, for example. This means that all data comes only from Google’s keyword planner, so these numbers are not entirely representative of the Internet.

7: Soovle

Last but not least, Soovle is a relatively simple but effective free keyword research tool. If you have ever used Google Autocomplete to identify keywords for your website content, then this will be very familiar.

All you have to do is type in your search term and click “Soovle.”

The results you see were taken from a variety of sources. In fact, you will see terms visually organized by search engines, from Yahoo to Bing, YouTube, and, of course, Google, to ensure that you cover all your basics.

Of course, there are not many results on this platform, but you can create a default platform (in my example, this is Google) that will give you a few extra suggestions for this particular platform.

It’s fast, it’s effective, and it’s just what you need on days when you’re struggling with ideas and/or resources.

Keyword Tip: Once you use your keyword research tool, make sure you show Google every search term you use in your content and use it in the top three. Your goal is to get all three websites – or, better yet, beaten – so you need to make sure that your website outperforms them in terms of content quality, design, format, and keywords (of course!).

Free vs. Paid Keyword Research Tools

Free keyword research tools are ideal for new businesses, beginners, or anyone who is just familiar with the SEO world.

However, if your SEO knowledge is more advanced or your company is growing fast, it may be worth considering a paid tool. Why? Free keyword tools tend to offer an abundance of results that take time to sort out, and in the business world, time equals time.

In addition, paid keywords update results from enormous amounts of data according to low-competition keywords that will be more targeted to the target.

We recommend that you use the free tool before you consider the prospect of keyword research and establish your level of experience. Then, if your budget allows, switch to paid versions for optimal results.
