Keyword research for SEO: the ultimate guide

Keyword research is an essential part of your SEO strategy. It’s the first step in the SEO copywriting process. Before you create your site’s content, you should find out what search terms your audience uses. Their search terms are your keywords. Based on these keywords, you can start writing useful, high-quality, and findable content. In this post, we’ll take you through the steps involved in keyword research.

What is keyword research?

Keyword research is part of SEO (search engine optimization). It’s the work someone does to come up with an extensive list of keywords they would like a website to rank for. To obtain such a list, website owners need to dig into their desired audience and search engines. What search terms do people type into Google when looking for a particular product, service, business or type of organization? And what do they expect to find? With this list, website owners can create content that will attract more high-quality traffic to their site. Keyword research is never finished: repeating it regularly is essential to staying up-to-date!

Why is keyword research important?

Proper keyword research is important because it makes clear what search terms your audience uses. At Yoast, we frequently come across business owners who use one set of words to describe their products, while their target audience uses a completely different set of words! As a result, potential customers can’t find those websites. In other words: there’s a mismatch.

To avoid this mismatch, you should do thorough keyword research. This research will make sure that you use the same words as your target audience. In addition, you should also consider your audience’s search intent. This will help you figure out what exactly your audience is looking for. All that’s left is for you to write high-quality content that answers your audience’s questions!

Originality versus findability

What about originality? Isn’t it better to stand out from the crowd and use different keywords than your competitors? Let’s say you (or your marketing department) decides to give a product an uncommon name. This can be a smart marketing decision, because people could remember your product more easily. If you rent out vacation cottages instead of vacation homes, for example, you might stand out more.

But beware: very few people search for [vacation cottages]. So if you optimize your text for cottages, you’ll probably rank well on that specific term. However, because your audience uses a different word, you won’t generate a lot of traffic, and you won’t reach a large part of your potential customers.

Essential concepts of keyword research

Before we jump to doing keyword research, we’ll briefly explain some of its essential concepts.

Focus keyword

A focus keyword or keyphrase is the word or phrase you want a certain page on your site to be found for in Google. You determine your set of focus keyphrases by doing keyword research.

Long-tail keywords

Long-tail keywords are more specific and less commonly searched for than head keywords. They focus on a niche. The longer and more specific search terms are, the easier it will be to rank for them. Why? Because there will be less competition.

However, long-tail keywords are still worth ranking for! Because even though less people are searching for them, they might be more motivated to buy, subscribe, sign up, etc.

Keyword strategy

Your keyword strategy is about the decisions you make based on your keyword research. For instance, what content are you going to create first? Will you focus on the head or tail? How and where will you publish it? Will you create a piece of writing, a post or a product page, a video tutorial or an infographic?

Search intent

Digging into search intent is key here: you have to discover what a searcher actually wants or needs. You’re not just looking at keywords. You’re also looking at the underlying goals of what a searcher wants to know, do or buy. Your content should provide a solution to the searcher’s “problem”. This is also known as content design.

How to do keyword research in 10 steps

There are 10 crucial steps to follow when carrying out keyword research. We’ll guide you through the process, and give you practical tips so you can conduct your own keyword research:

  1. Think about your mission and determine your SEO goals

    Before you start, think about your mission. Reflect on questions such as: What is the main goal of your business or organization? What makes it special? Who exactly are you trying to reach? And, what promises do you make on your website? Take your time and literally write down your mission. Once you’re able to answer these questions in detail, you’ll have taken the first and most important step in developing your keyword strategy.

    What if you’re in a competitive market?
    The market you’re in determines whether you’ll be able to rank high with your chosen keywords. Some markets are highly competitive, with large companies dominating the search results. It’ll be hard to compete with these companies, because they have huge budgets for marketing in general and SEO in particular.

    If you’re launching into a competitive market, your best bet is to start out small. Once you ‘own’ a small part of that niche and become a bigger name in your business area, you could try to level up and sell your cruises to a larger (more general) audience. Your mission will then become more general as well. The scope of your business mission should align with your SEO goals, too. Be realistic about what kind of rankings you can achieve with the size of your business, and focus on what will help you achieve your mission.

    An example
    Let’s say you sell cruises to Hawaii. You offer great facilities for children, which makes your cruises especially suitable for parents with younger kids. If there are no other family-friendly cruises to Hawaii, you will stand out from the crowd. It will make your service unique. So it would be smart to make this your mission, your niche – because this is what you have to offer your audience.

  2. Make a list of keywords you think people might search for

    The second step is creating a list of your keywords, preferably in a spreadsheet (like Google Sheets or Excel). With your mission in mind, try to get into the heads of your desired audience. What will these people be looking for? What kind of search terms could they be using, while looking for your amazing service or product? Which of their “problems” does your product solve? Write down as many answers as possible. If your mission is clear, you will have a pretty clear image of your niche and unique selling points (the things that set your business apart from others). These are the search terms you want to be found for.

  3. Research the keywords you’ve come up with

    After you’ve created your first list, it’s time to dive deeper into your keywords. Luckily, there are keyword research tools that make your keyword research easier.

    One of the easiest tool to use is Google itself. Google the keywords you came up with and check what Google suggests while you’re typing. Those are the questions people actually asked Google! You can also check out the “related searches” on Google’s results page. Also have a look at our related keyphrases tool in Yoast SEO or Answer the public.


    These tools will provide you with all kinds of variations of your keyphrases, synonyms and related keyphrases. Check them out and add the relevant keyphrases to your list.

  4. Use your research to find long-tail variants of your keywords

    When people start out with keyword research, they tend to focus on very popular “head” terms. Unfortunately, those head keywords are mostly taken by large businesses. Long-tail keywords, on the other hand, get less search traffic, but there’s less competition too. Therefore it’s easier for you to rank on those keywords. Moreover, long-tail keywords even have a higher conversion value, as they focus more on a specific product or topic.

    An example
    A long-tail keyword often is longer and more focused than a head term. If your head term is [puppy training], a long-tail keyword could be [positive puppy training for Labradoodles in Amsterdam]. Using the tools mentioned in step 3 will also help you find more long-tail keywords. You might also find some less-searched variants of your keywords, you can benefit from using these too.

    Use both!
    Don’t forget to add the long-tail keywords and your keyword variants to your spreadsheet too. Put the head terms in the first column and add (multiple) columns for long-tail keywords and variants. This will also help you create a proper site structure later on. The more long-tail your search term is, the further down into your site structure its landing page belongs.

  5. Analyze your competition for those keywords

    Whether you should go after long-tail keywords largely depends on your competition. If the competition in your niche is high, you’ll have a hard time ranking on competitive head terms. If you have little competition, you’ll be able to rank for more of your head terms. So you’ll need to do some benchmarking for SEO.

    Google the keywords that came out of your keyword research. Start with your most ‘head’ term. Check out the search engine result page (SERP). These are the websites you’ll be competing against once you optimize your content for such a keyword. Take a closer look: Do you see professional websites? Company websites? Are you ‘equal’ to these companies? Does your website fit among these sites? Is your company of similar size and does it have as much influence in your niche?


    It’s harder to rank when you’re competing against sites with strong brand names, like Royal Caribbean and Princess in the example above. If brands are known from TV or radio commercials, your chances to rank high will become even smaller. But it won’t hurt to take a look at their content. Is the content well written and well optimized? If your competition has poor content, you might have a chance to outrank them!

    Check Google Ads
    You can also take a look at ads in Google. Are there any? If you have a Google Ads account you can check the pay-per-click value of each search term using their Keyword Planner tool. Search terms that have a high pay-per-click are usually also harder to rank for in the organic results.

    Make notes!
    Make sure to make notes in your spreadsheet about your findings for the keywords you’ve investigated! You can use colors like red, yellow, and green to mark which keywords are more or less competitive if you find that easier than writing notes.

  6. Take a closer look at search intent for each keyword

    Today’s SEO strategies should, for the most part, revolve around answering the questions people have or providing the best solution for their “problem”. Whenever someone enters a search query into a search engine, they are on a quest for something. Every type of question needs a specific answer.

    Learn about search intent
    Try to find out which intent your audience has when they type a certain keyphrase into Google. Do they have an informational intent (try to find information on a specific topic), navigational intent (want to access a specific website), commercial intent (want to research something before buying), or transactional intent (looking to buy something right now)?

    You can learn more about the search intent of certain queries by looking closely at the type of pages that already rank for that query. Do you mostly see product pages? Or a lot of informational blog posts? Do you see videos? Or is it a mix? These are all hints to what Google assumes the search intent of a certain query is. This post explains how to use the search results to create great content that matches the right intent.

    Find out which kinds of intent apply to your keyphrases and, again, add your findings to your spreadsheet!

  7. Determine a keyword strategy – which keywords will you target?

    Based on the data you’ve collected now, you can determine a keyword strategy. If you’ve followed the steps above, you should have a spreadsheet with a substantial amount of keyphrases, plus information about the competition and the search intent of your audience for those keyphrases.

    Now think about this question: How does my website hold up compared to the websites in the SERPs? Are you of equal size and marketing budget? Then go ahead and focus on those head terms. If not: try more long-tail keywords first. Focusing on a whole bunch of long-tail keywords combined could very well attract a lot of traffic. Once you’ve managed to rank for those long-tail keywords, aiming for more head terms will become easier.

    When you’ve decided where to jump in, think about the type of content: What was the search intent for my keyphrases? What is my audience looking for? But also, which content can I create that isn’t there yet, and how can I stand out in terms of quality or providing solutions? This will help you decide on the type of content you’re going to create.

  8. Create optimized landing pages for your keywords

    In theory, this step is out of the scope of keyword research itself. Nevertheless, creating awesome landing pages is essential if you want to get traffic to your website. So, you’ll need to build optimized landing pages for your search terms. You don’t have to create all these pages immediately – it can be a long-term effort. Your keyword strategy will help you prioritize.

    Cornerstone content
    For your most important keyphrases you’ll create cornerstone content articles; articles that provide the best possible content about that keyword – authoritative and all-encompassing. All your supporting long-tail articles should link to your cornerstone content pages. This is part of your internal linking strategy, which Yoast SEO Premium can help you implement. You can also use our SEO workout: the Cornerstone content approach to build a strong internal linking strategy in a few easy steps.

  9. Evaluate if your keyword strategy is working and keep improving

    Once you’ve done a thorough analysis of your chances to rank on each specific term, published some amazing articles (and optimized them accordingly), you should wait a little. Check out your rankings. Does your article pop up? Did it hit the first page of Google’s SERPs? Or is it hidden away on page 2 or 3? Make sure to evaluate your results in the SERPs.

    There are various ways to check how your content is performing in the search results. The simplest way is to Google the terms you’ve optimized your articles for. Another option is to use Google Search Console to find out which queries you’re ranking for. While the Google Search Console method is a bit more complicated, it can be a great way to find new opportunities! And finally, a third method is to use a keyword tracking tool to monitor your rankings; you can do this easily using the integrated Wincher features in the Yoast SEO plugin.

    However you do it, it’s always a good idea to check if your efforts are paying off. If you’re not able to rank on the first page, try to write another article, focused on an (even) more long-tail keyword. Make it a little bit more specific, more niche. And see how that goes. Evaluate again. Continue this process until you hit that first page of the SERPs!

  10. Refresh your keyword research and your content regularly

    As time goes on, things will change. Your audience may start using different words to search for what they want, so you might need to add new keywords to your sheet. And with the rise of generative AI, the competitive landscape is bound to change, either making it easier or harder to target particular keywords. Who knows? Blogging might not be relevant anymore.

    When you look at the situation from year to year, a lot can change. That’s why it’s important to reevaluate and refresh your keyword research once in a while. Take the time to update your sheet with the latest information. And don’t forget to keep your content fresh and up-to-date, too!

Quick keyword research

In an ideal world, you would do your keyword research, make a beautiful spreadsheet and create landing pages for each one. Your site structure would be flawless, and you’d blog and write every day, making your site rank higher and higher in Google. But we live in the real world.

Of course, your keyword research will not always be as extensive. And some posts or articles aren’t written as part of an awesome strategy, but just because the topic was in the news or something inspired you to write it. That’s just how these things work. But this doesn’t have to be a problem.

If you’re writing something that doesn’t exactly fit your strategy, this doesn’t mean you shouldn’t try to make that content rank. You could still use it to rank for something related to the terms in the list of your keyword strategy. Use the tools mentioned in step 3 and Google Trends to quickly check which keyword you’d like to rank for. At least, take some time to think about how to make your article or blog fit your strategy. After all, if you are writing valuable content, you might as well make it rank! You can find more tips on how to do keyword research on the fly in our focus keyword article.

Tips for keyword research

This all might sound pretty straight-forward, but we know it’s a lot of work and easier said than done. When put into practice, you might bump into some common issues or questions. Here we’ll give you some tips to make it work!

Prioritize your keyword list

How many keywords should you target? Well, we can’t tell you the exact number of keywords you should have, but we can tell you that you need a lot of them – as many as you can think of. However, more than 1000 keywords is probably too many! Even if you’re a reasonably small business, you’ll probably end up with a couple of hundred keywords.

But there’s no need to create pages for all of these straight away. You can add content bit by bit. Think about which keywords you want to rank for now (perhaps the more long-tail ones?) and which ones aren’t as important right away. Understand your priorities and plan the creation of your content.

A focus keyphrase and its synonyms only need one page

In the past, each of the keywords you wanted to be found for got its own landing page. Today, however, search engines are so smart that they mostly use search intent to give searchers the best answer to their questions. The page that answers those questions best will rank on top. Search engines also understand subtle differences between keywords, so you don’t have to create landing pages for every subtle variation of a keyword, like synonyms.

That doesn’t mean you shouldn’t use synonyms! In fact, synonyms can really improve the readability of your copy, so make sure to use them. Our Yoast SEO Premium plugin can help you with this; it allows you to optimize your content for synonyms and related keyphrases. You can fill in synonyms of your keyphrase under the SEO analysis tab in your Yoast SEO sidebar. If you want to fill in more than one, you can separate them by commas. When it comes to adding related keyphrases to your text, we have an awesome feature you will want to know more about. So let’s discuss that next!

Glossary of terms

In the following paragraphs, we use a few words that you might not be familiar yet. Such as related keyphrases, word forms and exact focus keyphrase. Don’t worry! We wrote a glossary of terms that can help you out when you’re not quite sure what we mean when we use a specific term.

Related keyphrases are words and concepts that deepen and broaden the understanding of your focus keyphrase. They even help Google better understand the topic you’re talking about. By using related keyphrases in your text, you can paint a complete picture of your focus keyphrase in the article you’re writing.

You might be able to think of a few related keyphrases, but we think using proper keyword data is the safest bet. That’s why we have a Semrush integration in Yoast SEO. It suggests related keyphrases and even shows you the search volume and trend for every keyphrase. As Semrush is one of the leading SEO and marketing software companies in the world, this will help you find the right related keyphrases for your content.

You can find this feature in the Yoast SEO sidebar and meta box. Simply go to the ‘Get related keyphrases’ button underneath the ‘Focus keyphrase’ field and click it. The first time you click this, you will need to connect your Semrush account or create an account and authorize Yoast SEO to use it. After you’ve connected your account, you will be able to click the ‘Get related keyphrases’ button and find related keyphrases right away:

Find related keyphrases without having to leave your post editor

The related keyphrase feature is available for free, but if you use Premium you can also use those related keyphrases to optimize your content with the related keyphrase feature. This feature allows you to add related keyphrases or synonyms to a field in the Yoast SEO sidebar or meta box. That way you can easily optimize your content for multiple keyphrases and synonyms. If you want to know more about this integration, we have an article on how to use the Semrush related keyphrase feature.

Check out results for singular and plural keywords

Should you aim for the singular or the plural keyword? Well, this depends on the query. As Google learns more about the search intent of your query, it is able to better guess what you’re looking for. For instance, if you search for book, you get different results than if you search for books. Apparently Google thinks that in the first case you’re looking for a definition, in the second case it believes you’re intending to buy a book. So make sure you know what you offer on your page and that it fits with the query and results Google gives on that query.

Yoast SEO Premium has word form support, so it automatically detects all the different forms of your focus keyphrase (known as keyword stemming). So, you no longer have to optimize your post for a specific word form. Optimizing your post has become a much more natural process. However, there are reasons why you’d still want to optimize for a very specific word form of a keyword. In this case, you can put your focus keyphrase in quotes: “best books ever”. Yoast SEO will now only take that exact focus keyphrase into account when checking your content.

Use a keyphrase only once

Beware, you shouldn’t use your exact focus keyword more than once. If you do, your rankings might suffer from keyword cannibalization. Google has a hard time distinguishing between content that’s very alike. Therefore it might rank very similar posts or pages lower.

Not sure if you used a focus keyphrase before? The post why and how to export your focus keyphrases with Yoast SEO Premium will help you get an overview of the focus keyphrases you’ve used before and on what page. Also, Yoast SEO gives you a warning in the SEO analysis if you use one twice.

Did you find out you’ve already used the same or very similar keywords or keyphrases on various posts and pages? Then, it probably makes sense to audit your content and perhaps merge/delete/redirect some of it. Here’s a step-by-step guide on how to solve keyword cannibalization issues.

Ready? Start writing!

Keyword research should be the start of any sustainable SEO strategy. The result will be a long list of keywords for which you’d like to be found. But the hardest part is still ahead: writing all that content. You should write articles and blog posts on every single keyword you would like to be found for. That’s quite a challenge.
