7+ Best Keyword Research Tools For SEO Agencies

If you run an SEO Agency business like us, you definitely need tools to make the job easier. The SEO tool itself is like an investment that will help in the process of optimizing the visibility and ranking of your client's website on search engine pages.

One of the must-have SEO tools for professional SEO agencies is a keyword research tool or also known as a keyword tool. But why is this one SEO tool very important?

Launching the opinion of one of the UK's Professional SEO activists, Neil Patel, it was explained that keyword research tools can help to find what words or phrases are used by the audience of a website to search for information.

For example, your website discusses SEO, then you must know what words or phrases are most often used by your website audience. So you will get information about what your audience wants to know.

In addition, keywords themselves make it very easy for Google to identify the topics you discuss in the content you present.

In this article, I will discuss a little about the recommendations for the best keyword research tools that you can use as one of the SEO tools to support your SEO Agency business.

Best Keyword Research Tool For SEO Agencies

Launching information from one of the professional SEO experts, Beau Pedraza on the search engine journal page, it is stated that there are 7 SEO Tools for SEO agencies for keyword research purposes. Some of these tools are as follows:

Google Keyword Planner

Google Keyword Planner - Best Keyword Research Tool

The best SEO tool that can be used to do keyword research is a tool called Google Keyword Planner. As you can tell from the name, this SEO tool is one of the tools developed by the Google company.

This SEO tool itself is a feature of this Google Ads ecosystem. In short, this tool is often used for Google Ads purposes, where users will be able to do the right keyword research for their Google ads.

Keyword planner can also show information about keywords and trends in an area/city (region). Even more interesting, this keyword research service can be used for free. So Google Keyword Planner has become one of the keyword tool choices for new or developing SEO agencies.

Moz Keyword Explorer

Moz Keyword Explorer

The next best choice of keyword research tool that is also recommended is Moz Keyword Explorer. This keyword tool provides a User Friendly aesthetic display in it that makes it easier for you to do keyword research, check keyword difficulty (KD), track website performance on the SERP and others.

To use this SEO tool developed by Rand Fishkin and Gillian Muessig themselves, the subscription fee you have to spend is around $99 for the standard package and also $599 for the premium package.


SEMrush - Best Keyword Research Tool

SEMrush can be said as one of the SEO tools that has a very good reputation among SEO practitioners. This keyword tool, which was first launched in 2008, is also the choice of many large SEO agencies to explore potential keywords to target.

SEMrush itself has a feature that allows you to explore paid and organic keyword data, as well as information from competitors for keyword information. 

To use SEMrush, you only need to enter the term or topic you want to search for. Furthermore, this SEO tool will present thousands of keyword ideas that you can use.

Not only that, SEMrush can also check the long tail keywords in the SERP that your competitor's websites have conquered. 

For the subscription fee, it is known that to use this keyword tool, you must be prepared to pay a subscription fee starting from $90 per month for the Pro plan and also $399 per month for the Business plan. SEMrush itself provides 10 times free use (trial) for those of you who want to try both packages. 

Ahrefs Keywords Explorer

Ahrefs Keywords Explorer

Besides Moz and SEMrush, Ahrefs Keywords Explorer is also one of the best keyword tools according to Beau Pedraza. This keyword research tool can be said to be the most powerful among other SEO tools. 

Ahrefs Keywords Explorer is said to provide more keyword databases than other keyword tools in the marketplace. Not only that, the keyword database presented by Ahrefs Keywords Explorer is also presented with supporting information such as search volume, click data, Return Rate and Keyword Density.

However, the subscription price which is quite expensive is the only weakness of this SEO Tools. Note that the subscription fee for Ahrefs Keywords Explorer starts at $99 per month for the Lite plan and $999 per month for the Agency plan.

BrightEdge Data Cube

BrightEdge Data Cube

Most of you who haven't studied SEO for too long, may have never heard of a keyword tool called BrightEdge Data Cube. This one keyword tool is also quite well known among professional SEO practitioners abroad. 

One of the advantages of the BrightEdge Data Cube is that its design is quite simple, making it easy to understand and use. This tool itself can display keyword recommendations based on the terms or topics you are searching for. 

Even more interesting, the BrightEdge Data Cube also provides keyword recommendations based on the level of competition, ranging from high, medium to low competition rankings.

Besides being able to be used for keyword research, this SEO Tool can be used for client reporting, domain management and also integration with Google products and also Adobe Analytics.

For the problem of subscription fees, it is not clearly stated how much the subscription fee for this SEO Tool will cost. 

But after browsing on the official website page, I found that you can submit a demo request for this SEO tool. So you can feel first the experience of using this SEO tool, before deciding to make it an option or not.



If you are looking for a tool for keyword research that is inexpensive but provides complete and accurate data, Ubersuggest is an option that you can rely on. This SEO tool developed by Neil Patel has a user-friendly design, so it will be very suitable for use by beginners or experienced SEO practitioners.

To do keyword research using this one tool, you only need to enter the term or topic you want to search for. Furthermore, this online tool will immediately present data in the form of a summary section that contains various information, ranging from keyword ideas, search volume, CPC to the level of competition in the SERP.

Besides being able to be used to do keyword research, Ubersuggest itself is also equipped with many features that support various website optimization activities such as checking traffic (Organic Keyword, Organic Monthly Traffic, Domain Authority and Backlinks) and also conducting SEO Audits (checking SEO Score, backlinks, critical errors to suggested optimization information).

Talking about, the price for subscribing to Ubersuggest itself is still quite friendly. Based on the latest information, Ubersuggest offers 3 price packages that you can choose from, which include:

  • Individual ($12 per month)
  • Business ($20 per month)
  • Enterprise/Agency ($40 per month)



The last best SEO tool for doing keyword research is KeywordTool.io. Although not as popular as Ahrefs, SEMRush and Ubersuggest, KeywordTool.io can be said to be one of the keyword tools that has been widely used by SEO practitioners and bloggers, even today.

Similar to some of the keyword tools that I explained earlier, KeywodTool.io also presents data information from certain keywords that you use in the search. One of the other advantages of Keywordtool.io is that the interface is quite simple, making it easier for users to use it.

In addition, this one tool also provides searches in various languages ​​and is not only limited to keyword searches on Google, but also on other platforms such as Youtube, Amazon, Bing and even the App Store.

Actually this one keyword tool can be used for free. However, for free use, there will be some information that is limited and can only be accessed if you use the premium version (aka paid).

The paid version of SEO Tools is $48 per month for the Pro Lite version and $88 per month for the Pro Plus version.

Additional Options: Keyword Tool Dominator

Keyword Tool Dominator

In addition to some of the best keyword research tools I described above, there are other keyword tool options that you can also consider. The keyword tool is called Keyword Tool Dominator.

Not many articles discuss this one keyword tool, but Keyword Tool Dominator provides a fairly complete feature in it. This tool not only provides features for doing Google keyword research, but also other platforms including Amazon, Bing, Ebay, Etsy, Walmart and Youtube. 

The appearance of Keyword Tool Dominator itself is quite simple and User Friendly, so you will not take long to understand it.

Actually you can use this SEO tool for free, but if you want to access more features and use it without limits, then you are recommended to use the paid version for $74.99 for lifetime access.

Which Keyword Research Tool Is Best For Your SEO Agency?

Although in the discussion I share, I mention that the keyword tool above is the best SEO tool for doing keyword research. But actually there is no keyword tool that is absolutely perfect, all of them have their own advantages and disadvantages.

When it comes to choosing a keyword research tool for your SEO agency, the best option is to base your choice on the needs of your own SEO agency.

For example, your SEO agency only needs a keyword tool that provides keyword data, so Google Keyword Planner and Ubersuggest can be good choices. 

However, if your SEO agency needs other, more complex data such as ranking data, link sources and others, then keyword tools such as Ahrefs, Moz and SEMRush are keyword tools that you can use.

Discussion Summary

From a number of reviews that I submitted about the best keyword research tools for SEO agencies above, there are several important points that you can take. Some of these points are as follows:
