In this post, we are going to discuss the 11 best keyword research tools. Some of these tools are free while some are paid. We hope you will enjoy learning about these cutting edge tools. Keep reading!

What is a Keyword Research Tool?

A keyword research tool is primarily used to figure out what keywords your target audience is using to look for information, products or services.

It helps you come up with topics that resonate with your audience.

But the uses of a keyword research tool go beyond just figuring out the keywords your target audience is likely to use.

For example, it helps you with competitive analysis. If you drop your website URL into a keyword research tool, it will display the targeted keywords.

That means, based on the niche of your website, a keyword research tool recommends certain keywords.

Gone are the days when using lots of generic keywords was regarded as a good SEO practice. You need to learn about the essence of modern SEO practices.

Now you need personalized keywords coming from your search query reports. A good tool can help you find personalized keywords that can be grouped into focused clusters.

Modern keyword research tools come with features that can identify high-converting keywords. These keywords can help you convert your audience into customers who are willing to pay for your products or services.

These days, most people use long-tail keywords when looking for something online. These long-tail keywords are not intuitive or easy to think of.

One great thing about keyword research tools is that they can uncover long-tail keywords that you would otherwise fail to find.

There are some SEO metrics that can be used to improve your website’s ranking in search engines. Conversion rates, organic visits, inbound web traffic, and bounce rate are some reliable SEO metrics.

The right tool can help you analyze these metrics and improve your scores.

Highly sophisticated AI-powered tools make the process of analyzing these metrics very easy. Better yet, these tools are known for their user-friendliness. You can use them even if you have no prior experience.

With the help of an advanced keyword research tool, you can gain some insight into the current search trends.

With this insight, you learn the art of prioritizing your time. Whether you are building a sales funnel or simply doing some research for your next blog post, you no longer waste time focusing on less important keywords that hardly have any impact on your ROI.

As a digital marketer, your success depends on your ability to understand the real needs of your audience.

By using the right tool, you will have a far better understanding of the people who might need your products or services. It is like being able to read the thought patterns of your target audience.

Why You Should Only Write Blog Posts after You’ve Done Keyword Research

You have started a blog and now you are writing decent posts pretty regularly. However, there is a problem: your blog is not getting that many visitors. You might wonder why. Well, it may be because you did not do keyword research before writing the blog posts.

However, it is also important to remember that your content should not be dominated by keywords. Blogging is more than just using the best keywords in your posts.

Doing some keyword research is very helpful when you are trying to attract targeted traffic, but this is just a part of the entire process of writing and publishing content.

Over the past decade, search engine algorithms have become smarter. When it comes to providing search results, Google no longer relies on keywords; the search engine understands topics, just like humans.

However, that does not necessarily mean that SEO is dead. Skipping this part is one of the worst things you can do as a blogger or content marketer. Many novice bloggers make this mistake. They start writing without doing any keyword research.

As a result, even though they produce pretty good content, they fail to attract that much traffic.

There are plenty of reasons to do keyword research before you write blog posts. Let’s try to understand the main reasons.

1. You Can Choose Blog Topics Based on the Right Keywords

If you are a creative writer, you might hate this idea. But, let’s be practical. If you want people to care about a blog post, you have to make sure that they are already interested in the topic. Otherwise, you may end up wasting your time.

Serious bloggers are very careful when it comes to picking blog niches. And once you have picked the right niche, you have to write posts that make sense to your target audience.

With a keyword research tool, you can find keywords your target audience is using. You can choose your blog topics based on those keywords.

In order to relate to your target audience, you have to know what information, products or services they are actually looking for. And when you know what people are looking for, you will find it relatively easy to make them take action.

This is one of the most effective ways to improve your search engine ranking. If your blog topics are based on popular keywords, chances are that you will get much more traffic. More traffic means more customers and more sales.

2. You Can Use Relevant Keywords in Your Content

Google algorithms depend on artificial intelligence; they do not have feelings. They don’t understand the beauty of language; they just analyze words. If your blog posts do not contain the right words, the algorithms will not pay attention to the posts.

By doing keyword research, you can know what keywords you should use in the title, heading and body of a blog post. Using keywords in this way is another effective way to rank high in search engines.

But we should clarify one thing here. Stuffing keywords into your content is not the purpose of keyword research. The main purpose is to make your content purposeful and valuable. When you are writing a blog post, it is important to remind yourself why you are writing it in the first place.

It all comes down to looking at the content from the perspective of your target audience.

3. It Helps You Find High-Converting and long-tail Keywords

When it comes to choosing keywords, you have to be a bit strategic. Not all keywords can fetch business for you. So, you have to focus on only high-converting keywords. Keyword research helps you identify these keywords.

Simply drawing people from search engines means nothing. Providing value is what counts. If people do nothing after reading your blog posts, you will not get any reward for your efforts. It is important to focus on personal branding and let people know that you want to do business with them.

.Over the years, our understanding of keywords has changed. These days, the term “keyword” refers to a complete phrase, even sentence, rather than a single word. Yet, many people mistakenly assume that a keyword means a single word.

To look for products or services, people are using long-tail keywords these days. When looking for a graphic designer to design a logo for a landscaping business, one does not simply type “graphic designer” into the search bar.

The person is more likely to use keywords like “graphic designer in New York” or “logo designer for landscaping business”.

Google keywords search

Yes, you can choose to ignore it. But there are other graphic designers in your area, and they will optimize for Google algorithms to have an edge over you.

The key is to find a balance between using good keywords and creating conversion-oriented content. When using keywords, you have to think about both visitors and search engine algorithms. Using keywords for the sole purpose of drawing traffic can be counterproductive.

To some extent, it depends on your motive behind writing blog posts. If you are writing primarily to raise brand awareness, converting your audience into customers is clearly not your primary concern.

With that said, for a content marketer, doing keyword research before writing blog posts is of utmost importance.

Long-tail keywords are very specific 3 or 4-keyword phrases. They are highly profitable; because customers using long-tail keywords are looking for products or services they actually want to buy.

Most often, these specific searches lead to sales, and therefore they are much more valuable than generic searches.

Guessing valuable long-tail keywords can be hard. Keyword research tools can help you find long-tail keywords more easily. For finding such keywords, some tools are more useful than others.

More and more people are using long-tail keywords these days. About 70% of queries are now long tail, and they convert about 3 times more frequently. For all these reasons, SEO strategists are now paying attention to long tail keywords.

3. Keyword research tools provide you with all the relevant user search metrics

User search metrics can help you have a deeper understanding of your target audience. Different metrics can be used for different purposes. And keyword research tools provide you with relevant metrics.

Search volume, average CPC and Google trends statistics are some very useful metrics. You can use these metrics for many purposes, even for starting an online store.

Average CPC (cost-per-click) can help you make important decisions about your paid advertising campaigns. This metric can help you with your organic keyword research.

By looking at this metric, you can know how much your competitors can pay for their visibility in ads for the particular search. That means, average CPC lets you know the real value of a particular keyword.

For example, if the average CPC of a keyword is $0.50, you may not want to invest your time in that keyword.

If the average CPC of a keyword is $7, it means that people are paying a good amount of money to show up in ads for the search. Depending on your brand, the keyword may or may not be too competitive for you.

With keyword research tools, you can also learn about Google trends. That means, the tool will let you know whether a particular topic or keyword is trending. This data can be used to know how trendy particular search terms are.

There are many other useful metrics, and all tools do not show the same metrics. To calculate metrics, different keyword research tools use their own algorithms. That is why one tool may not display the exact same figure as the other.

How to Research Keywords For My SEO Strategy

Keyword research involves gathering keywords that your target audience might be using to find your business.

To find keywords, you do not use a tool from the very beginning. It all starts in your head and then you use tools to augment the process.

Here are some step-by-step instructions for keyword research for your SEO strategy.

Step 1: Make a list of important, relevant topics you want your business to be associated with

If you already have a clear idea about different aspects of your business, you are welcome. Consider using a business model canvas to visualize the building blocks of your business.

Think about different aspects of the business you want to focus on, and try to come up with relevant topics. At this stage, you do not have to be very specific. Just try to find topics you think should be associated with your business.

You may find this process easier by putting yourself in the shoes of your target audience. Think about your buyer personas. Look at your business from your customers’ perspective. What topics would they search to find your business?

Here is an example. If you are specializing in products for men’s personal care, you might think about topics such as

  • Shaving cream
  • After shave lotion
  • Male pattern baldness
  • Deodorant
  • Gym equipment

Come up with as many topics as you can. Based on these topics, you can find specific keywords later.

Finding relevant topics is easier if you have sufficient knowledge about your niece. You can do some research online and learn about different aspects of men’s personal care.

Before you start using a keyword research tool, visit as many relevant websites as you can. It will expand your knowledge about the niece and give you fresh perspectives. This approach will also help you learn about the trends in this field.

Step 2: Fill those topic buckets with keyword ideas

Once you have several topic buckets, you have to identify keywords that belong to those buckets. These keywords are the ones you think your target customers might be using to look for businesses like yours.

Take, for example, the last keyword bucket. With the term gym equipment, you can brainstorm keyword phrases related to the topic. These are words or phrases people would use when they need to learn more about gym equipment. They might include

  • Best gym equipment for stretching
  • Fitness equipment brands
  • What are the best fitness accessories
  • Training accessories
  • Training equipment
  • Best equipment for six pack

A keyword research tool like Semrush can make this process a lot easier. To figure out what terms people are using to find your website, you can take a look at the Explorer tab. Here are some content ideas based on the term “snowboard bindings”.

This way you can come up with words and phrases that are related to the main keyword. However, this is not the final list of keywords.

These are just terms your target audience might use. So, the list may be pretty long. You will have to narrow down the list later.

Here is another thing to consider. People are already using certain terms to find your existing content. By finding more keyword ideas, you can figure out the terms people are already using to look for your business.

People in sales can also help you come up with these terms. These people talk to customers and therefore know what customers are actually looking for.

Talking to experienced salespeople can help you in other ways too. These people can provide insights into what is actually happening on the ground. These insights can help you develop your business strategy and work ethic.

If you have thought about the process of keyword research, you already know what related terms mean.

When you type a specific keyword into Google to look for something, the search results include not only related websites but also related search terms at the bottom of the page. By looking at these keywords you can come up with more ideas that might be worth considering.

And you can get a bit more creative with these related terms. By typing each of these terms into the search bar, you can get many more related terms.

Related searches give you an insight into the search intent of your target audience. By understanding this search intent, you can create content that is relevant and valuable.

SEMrush has an amazing feature that makes it very easy to find related keywords. Within the Keyword Magic feature there is a filter that detects valuable related terms.

And when you have found many keywords related to a seed keyword, you can think about the subject from different perspectives.

This is an ability that can be helpful for your other projects. For example, to create a webinar, you must understand how your marketing strategies are perceived by your audience.

If you enter the term “basketball shoes”, the tool shows you the number of searches per month, and a score that helps you understand whether the keyword would be profitable. The tool also displays many other terms related to the original term.

By entering these search terms into your keyword research tool, you can understand their competitiveness.

In recent years, Google has become highly sophisticated. To provide search results, instead of relying solely on keywords, Google also analyses the intent behind a search.

Therefore, in order to boost SEO efforts, understanding search intent is a must. By understanding it, you can create content that your customers are already interested in. and Google will rank the content highly.

SEO optimization is easier when you have a convenient way to generate on-site content ideas. By being a bit strategic, you can use related keywords to generate fresh ideas and increase your SEO ranking.

Step 4: Include head terms, body keywords, and long-tail keywords

Head terms are phrases with a high volume of searches. They are broad in nature. The term “fitness accessories” can be a head term, with subcategories such as push up frame, rowing machine, and stationary bicycle.

Head terms have the highest competition. It is very hard to convert these generalized keywords, partly because it is almost impossible to predict the intention of the people using these broad terms.

head terms have highest search competition

Body keywords are 2 or 3-word phrases with a good amount of search volume, but lower than head terms. They are pretty specific. These terms are very competitive and define broad niches. Direct mail advertising is an example of a body keyword.

Long-tail keywords are highly specific phrases of 4 words or more. They are less frequently searched-for, which means these keywords have a low search volume.

It is a good idea to focus on long-tail keywords, because they are not highly competitive. People using these hyper-specific terms are already willing to buy the products or services.

While head terms have the lowest conversion rates, long-tail keywords have the highest. So, instead of focusing too much on head terms, it is wise to focus on body keywords and long-tail keywords.

Step 5: Research what your competitors are ranking for

All site owners should do competitive analysis, because it provides you with a roadmap for improving your site. One of the best ways to understand the strengths and weaknesses of your website is to compare it with your competitor’s website.

The comparison can give you valuable information that can be used to boost your SEO efforts. By identifying the weaknesses of your competitors, you can figure out what you can do to have an edge over them.

You should do competitive analysis even if your website is doing very well and ranking at the top. Remember, your competitors are always trying to identify your weaknesses and capitalize on those weaknesses.

If you do a little bit of research, you will almost always notice that your competitors are doing something better than you. Maybe their blog is doing better or their articles are getting lots of shares.

You can examine their content and think about ways to improve yours. This is in fact one of the essential qualities of a leader. In order to become a leader in your field, you have to understand both strengths and weaknesses of your competitors.

However, identifying your real competitor can be a bit tricky. Your biggest competitor may not be the one doing very well with the “money keywords”.

Again, if you notice that for certain keywords, only Wikipedia or Pinterest are raking above your site, you know that they are not your actual competitors.

It is important to pay attention to the keywords your website is already ranking for.

Look at the screenshot below. If you are Home Depot, you will notice some keywords where you are close to the top spot for “air compressor” and “swing sets” phrases. Both of these terms have large search volumes.

Again, looking at the main competitor is not enough. Here, Home Depot dominates on some terms that are common to all competitors.

When doing competitive analysis, make sure you ask yourself the following questions.

  • What are they doing differently to rank high?
  • What supplementary content do they have for these keywords?
  • Do they have many backlinks to the pages responsible for their high ranking?

The key here is to identify the keyword gaps and then close the gaps. In most cases, you can fix the issue by creating some new content or adjusting your current content.

Understand Keyword Metrics to Grow Your SEO Traffic Faster

Whether you are trying to make money blogging or improve your online marketing strategies, you have to take keyword metrics seriously. Keyword metrics should determine your important decisions about online marketing.

For an SEO strategist, measuring the success is one of the hardest and most important jobs. Search engines do not update SERPs overnight. That is why relying solely on your search engine ranking is not a very effective way to track your progress.

Analyzing keyword metrics is a more cohesive methodology. Here are some important keyword metrics that can help you understand your progress and grow your traffic faster.

Search Volume

With this metric, you can know the average number of times a particular term is searched per month. Search volume represents the number of searches; it does not tell you how many people have searched the term.

SEMrush is often referred to as one of the best tools to measure search volume. To see this number, you just have to enter the term in the search bar and click Keyword Overview.

SEMrush allows you to view a keyword’s global volume as well as regional volume.

This metric is updated once in a month. The calculation is performed with recent search data. If needed, you can also have access to historical data.

With the Keyword Difficulty and Competition Level metrics, SEMrush lets you know the competitiveness of keywords. SEMrush uses its highly sophisticated machine learning algorithms to calculate search volumes.


People type keywords into search engines to look for information, products or services. But people do not always click on search results.

The Clicks metric lets you know the average number of clicks a specific keyword receives in a month.

The number of clicks for a keyword can be far below the search volume.

There is a reason why this happens. Google now answers many questions in brief, in the search results. To find information, people do not always have to click links and visit websites.

This metric can be used to weed out keyword ideas that have very poor search traffic potential. We should note here that paid ads sometimes get lots of clicks.

Traffic Potential

This metric gives you an estimated number of your potential users. With the help of this metric, you can find effective ways to improve your website’s position for certain keywords.

Semrush Traffic Potential
Source: Semrush

It is helpful to find keywords that are related to your business, but that’s not enough. You have to figure out actually which keywords bring traffic.

SEMrush calculates the estimated traffic of a domain by multiplying its click-through-rate by its keyword volume and then dividing the number by 30 (because there are 30 days in a month).

The traffic potential metric, referred to as Estimated Traffic in SEMrush, is not available until the tool collects the volume and CPC data. Therefore, you may not see this metric just after launching your new campaign.And you can get the best out of this metric if you use other SEO tools to improve your rankings.

If you have added new keywords to your existing campaign, they will not have any impact on this metric. The impact will be noticeable once the tool has collected data for the Volume and Rankings metrics.

This metric tells us that keywords should not be judged solely based on their search volume.

Keyword Difficulty

The keyword difficulty score predicts how difficult it would be to rank for a specific keyword. This is one of the most important metrics, and almost all keyword research tools provide this metric.

SEMrush is known as one of the best tools for measuring keyword difficulty. Like some other tools, it displays the score in a percentage of 0 to 100.

Semrush keyword overview on running shoes
Source: Semrush

Difficulty scores can be grouped into 3 levels: high difficulty, medium difficulty and low difficulty.

High difficulty refers to a score of 80% or more. If the difficulty score is over 80%, you will probably have to invest heavily in SEO practices. If your site is a brand new one, you may not want to target these keywords, simply because they are not worth your time.

If the score is from 60% to 80%, it is considered medium difficulty. With this level of keyword difficulty, it will not be easy to rank high. However, if your site already has some level of authority, you can consider targeting keywords with medium difficulty.

If the difficulty score is below 60%, it is considered low difficulty. Keywords in this range are very easy to rank for, but they are very hard to find. Low difficulty keywords with steady search volume give you great opportunities for ranking high.

But that does not mean that you should focus only on low difficulty keywords. Your blog can bring your real prosperity only if you can master the art of using both low difficulty and high difficulty keywords. There are at least two reasons why you should care about high difficulty keywords.

First, to rank high, you are going to need many backlinks. Therefore, you should not be late in creating your page and promoting it. You will find it harder to outrank your competitors if you delay.

The second reason is that keywords with high difficulty scores provide link opportunities. Top-ranking pages have link-worthy topics, and that is why they have backlinks. In other words, you can attract backlinks only if you nail your topic.

Here is one last thing to consider. Before you go after a specific keyword, you should assess it manually. Relying blindly on a keyword difficulty score, no matter how accurate it is, can be counterproductive.

Cost per Click

Cost per click is the price that you pay for the clicks on your pay-per-click ads. The amount you pay impacts several aspects of your campaign’s performance.

Advertisers can greatly benefit from this metric. It lets advertisers know the number of clicks they receive for a budget.

semrush cost per click
Source: Semrush

As an advertiser, you can benefit from learning about the visibility of your ad. You can know how frequently your ad is shown and decide whether to keep running the ad.

Your campaign is successful only when you can drive the highest ROI while making the best use of the opportunities for sales. Bids should not be set too high or too low.

If your bids are set too high, it will impact your profitability. And if they are set too low, your ads will not be shown frequently.

SEMrush allows you to set a maximum CPC, but this is not the final price that you pay. You are charged the minimum amount, because you pay only if people click on your ads.

Let’s try to understand Maximum CPC, Average CPC and Actual CPC.

Maximum CPC is the amount you agree to pay per click. You set this amount in your ads account.

Average CPC is an amount that refers to the total cost of the clicks ÷ the number of clicks.

Actual CPC is the price you actually have to pay per click.

As a metric, CPC is far less stable than search volume. CPC is volatile and can change any time.
