How to Do Keyword Research for SEO: Finding the Right Target Keywords for Your Content

Introduction

Whether you’re a business owner looking for the right target keywords to work on, a blogger looking to kickstart their online journey, or a marketer working on one or multiple profiles, keyword research for seo is and will always be the first step towards content curation.

It is so much more than finding high-volume keywords and working on it; you need to finalise keywords that genuinely work for you – not only fulfilling your search intent, but also your primary and secondary goals. Its right implementation is the difference between businesses attracting wrong traffic — and those with the right one, bringing in leads.

In this guide, you’ll learn how to do keyword research for SEO step by step. How you can discover the right keywords, evaluate them, understand their types, and avoid common mistakes that take you downhill.

Let’s get into it.

What Is Keyword Research and Why Does It Matter?

Keyword research is the process of discovering keywords and phrases users search on Google and other search engines – to find out information that can help them & guide them towards the next step.

It is the foundation of SEO – serving as a bridge between users and relevant information. When a user navigates to Google or Bing – and types in their query, the search engine, rather than treating it as a set of disjointed words – it did initially- now combines it to understand the context and deliver the relevant results. The posts, products, service pages, and videos you see as a result can help solve your intended purpose – often channeling you towards that stage of the customer journey where you voluntarily look out for businesses & service providers.

Remember, the journey towards user satisfaction is not linear. And, since keyword research serves as a starting point, it is precisely where a significant number of brands and marketers lose their way.

This is why choosing the right keywords is the core of your strategies.

Without it, your content can only rely on assumptions. You may spend hours creating an article around a topic that no one is searching for, or target a highly competitive keyword that’s difficult to rank for. In both cases, the effort rarely produces meaningful business results.

Before You Find Keywords, Understand Who You’re Trying to Reach (Know Your Audience)

While the stance of keyword research being the first step of strategisation or content curation is true, experienced professionals would argue otherwise. Those who know their business goals, target audience’s needs, pain points, the psychology behind the questions they ask, and the language they use rarely start with keywords. Instead, they start with the human behind the search.

Keywords simply become a reflection of that understanding – not the foundation.
Sounds too technical? Let’s understand with an example.

Say you’re a digital marketer in Mumbai, tasked with helping local businesses grow. You’ve got two clients. The first is an interior design studio that creates luxury homes. The second sells affordable furniture for small apartments.

You can see that both businesses belong to the same industry. They could easily end up targeting the wrong audience if they were to go with broad keywords like ‘interior designer’ or ‘home decor’.

Understanding the different intent behind similar searches and then going with the keyword research step customised to the audience is what makes a good strategy land, and a bad one fail.

Someone planning a premium villa renovation might search for ‘luxury interior designer in South Bombay’. Whereas, let’s say a couple furnishing their first apartment would more likely search for ‘affordable home decor for 1BHK’ or ‘modular furniture for small flats’.

If you ignore these differences and target the same keyword for both businesses, the content may attract visitors – but not necessarily the right audience.

As a business owner, manager, or entrepreneur, your first step should be understanding your customer. Ask yourself these few simple questions:

• Who is my ideal customer?
• What problems are they trying to solve?
• What questions are they asking before making a decision?
• What words would they naturally use while searching online?
• What action do I want them to take after finding my content?

The answer to these questions becomes the foundation for your keyword research.

How to Do Keyword Research for SEO: A Step-by-Step Process

Follow the steps below whenever you start your SEO keyword research journey:

Step 1: Understand Search Intent Before Choosing Keywords

Before finalising the keywords from your Semrush or Ahrefs list, ask yourself, “Why is someone searching for this?” When you understand this, you automatically come to know what their expectations are without making assumptions. Then, you can effortlessly match & finalise the keywords.

Keep in mind that a single seed keyword can have multiple intents.
Ex:

• interior design ideas
• hire interior design consultant

Though the two are phrase match -with exact order seed keyword, the intent differs. The first one is looking for ideas and inspiration, while the second one is actively searching for providers and is close to making a decision. A single seed keyword can have different intents across different stages of the customer journey.

This is why understanding search intent is fundamental before you start choosing keywords. If you’re looking to understand what search intent is in-depth, read our blog – Search Intent in SEO: The Complete Guide to Better Rankings, Traffic & Leads.

Step 2: Start with Seed Keywords

Once you’re done with intent classification, it’s time to identify your seed keywords.

Seed keywords are basically the roots of your keyword research and strategy. They are the initial input used to discover low-competition, long-tail, and short-tail keywords. You don’t target them directly. Instead, they act as the foundation for uncovering more specific search queries.

With the interior design studio example, seed keywords might include:

• interior design
• home interiors
• modular kitchen
• bedroom design
• office interiors

Your goal is simple – to capture the main topics of your audience and their business. One useful way to do this is to think about:

• The core products or services you provide to your audience.
• Pain points and specific problems your customers are desperate to solve.
• Burning questions they ask before making a final decision.
• Natural industry terminology your target audience use in their daily lives.

Step 3: Expand Your Keyword Ideas

Once you have a list of seed keywords, it’s time to expand them into real search opportunities. It’s necessary at this stage that you stick with one seed keyword at a time – and build clusters around it.

For example, if you choose “home interiors“, your expanded keyword list might include:

• home interior design
• home interior design ideas
• modern home interiors
• luxury home interiors
• affordable home interior design, etc.

Once you’ve exhausted one seed keyword, repeat the same process for the remaining seed keywords—interior design, modular kitchen, bedroom design, and office interiors. Over time, these individual keyword clusters come together to form a comprehensive SEO strategy around your business.

Now, at this stage, one of the most common misconceptions that even experienced marketers have is that the seed keyword is the same as a product or service page. It isn’t. A seed keyword is simply the starting point of your keyword research.

Ex: for seed keyword “home interiors”, → your service page can have its keyword extend from seed keyword to “home interior design services”. Equally, the same seed keyword can be used to create blog posts, glossaries, guides, and insights.

There is no rule that a seed keyword is only meant for a service page. Depending on the topical clusters and the comprehensive SEO strategy you want to build, a seed keyword can become the foundation for both commercial intent pages and informational content.

Step 4: Understand the Different Types of Keywords

By now, you would’ve generated a list of potential keywords from seed ideas. The next step isn’t choosing the keyword with the highest search volume—it’s understanding what role each keyword plays.

Here are the five types of keywords everyone should know:

Short-tail Keywords

Short-tail keywords are broad search terms, made of one or two words.
Ex: ‘Interior Design’, ‘SEO, ‘Content Marketing’, ‘Content Writing’

These keywords are often high in search volume and difficulty. Your strategy – be it on-page, off-page & technical – when implemented in a unified manner, utilising best SEO, EEAT practices, will lead to long-term organic visibility. Remember, ranking on such keywords for a new website is next to impossible, unless you’re a strategy god.

Long-tail Keywords

Long-tail keywords are more specific and made of three or more words.
Ex: ‘Interior designer for small apartments in Mumbai’, ‘SEO Agency in Mumbai’, ‘SEO content writing for B2B business’.

These keywords have mid to low range search volume, where the keyword difficulty depends on the number of competitors, their backlinks’ strength, trends, search intent, and content quality.

Such keywords, though fewer in searches, when properly optimised, will lead to organic traffic, qualified leads, and ultimately the fulfilment of your primary and secondary business goals.

Informational Keywords

Such keywords aim to provide information to the audience with the intent to bridge their knowledge gap – ensuring they know and make informed decisions.

Examples include

• What is keyword research?
• How to improve SEO
• Interior design ideas for small homes, etc.

Best content formats for such keywords are – step-by-step guide, blogs, tutorials, FAQs, etc.

Commercial Keywords

Commercial keywords constitute the Middle of the Funnel (MOFU), where users want a clear comparison of the USPs and key aspects so they can choose the best option.

Examples include:

• Best SEO agency in Mumbai
• Top keyword research tools
• Best interior designer for apartments

Best content format for such intent is – comparison posts, honest opinion/review articles, case studies, testimonials, pricing, calculators, and other types of lead magnets.

Transactional Keywords

Such keywords constitute the Bottom of the Funnel (BOFU), where users are ready to take action.

Examples include:

• Hire SEO consultant
• Book interior designer in Mumbai
• Buy keyword research software

These keywords are ideal for landing pages, product pages, and contact pages because the searcher is much closer to converting.

When Should You Use Each Keyword Type – At a Glance Understanding

Keyword Type	Best Used When…	Example
Short-tail	Building broad visibility over time	Interior design
Long-tail	Targeting specific searches with lower competition	Interior designer for small apartments in Mumbai
Informational	Educating and informing Top of the Funnel audiences	Interior design ideas for small homes
Commercial	Helping users compare options before choosing	Best interior designer for apartments
Transactional	Encouraging enquiries or purchases	Book interior designer in Mumbai

Step 5: Evaluate Each Keyword Before You Choose It

Once you’re done selecting either long-tail or short-tail keywords based on their intent – informational, navigational, transactional, or commercial – the next task is to evaluate their search volume, keyword difficulty, business relevance & ranking potential.

Here are the five factors, at a glance, that contribute to your decision-making.

Factor	Ask Yourself
Search Volume	Are enough people searching for this keyword in a particular location?
Keyword Difficulty	Can my website realistically compete and rank for this keyword?
Business Relevance	Will this keyword attract the audience I actually want to reach?
Search Intent	Does this keyword match what my audience wants?
Content Fit	Can I create content that is genuinely helpful and not just a repetition of what’s already available?

The goal is to choose keywords that rightly balance the opportunity, relevance, and your ability to create genuinely valuable content.

Step 6: Choose One Primary Keyword and Supporting Keywords

It is at this stage that you define your primary keyword based on search intent, search volume, keyword difficulty, business relevance, and ranking potential.

The remaining relevant keywords become your secondary keywords.

Ensure that your primary keyword aligns with the intent of the topic you want to cover, while your secondary keywords are naturally incorporated as exact matches, phrase matches, or query matches within relevant H2s and H3s.

This grouping of relevant secondary keywords into major headings helps target for topical authority, bringing in traffic not just from the primary keyword, but also related & connected keywords, ultimately strengthening the content quality & SERP positioning.

Keyword Research Tools Every Business Should Know

Your keyword research journey becomes less stressful and a little more fruitful when you know what tools to use.

The right tools, when combined with the right strategy, help build authority and clusters, which makes your website appear a trusted source, an authority you can rely on.

While the process should always begin with understanding your search audience and intent, the right tools help validate ideas, make better decisions, and discover new opportunities.

Here’s a simple overview of the most useful keyword research tools and when to use them.

Tool	Best Used For	Ideal for
Google search	A crucial, free tool is your Google search, where you get autocomplete suggestions on primary and secondary keywords by looking at the dropdown suggestions. You can also utilise the PAA ‘People Also Ask’ and ‘Related Searches’ section to do keyword & query research	Everyone at any stage.
Google Keyword Planner	One of Google Ads’ offerings, the Google Keyword Planner, helps find keyword ideas with search volume & trends.	Beginners & businesses
Google Search Console	When you create your website & connect with the Google suite, Google Search Console helps you see on what queries your pages/ and posts are gaining impressions. And, work on it – either by creating a new supporting post, or its natural inclusion – so you stay optimised and updated.	Existing websites

If you are looking for comprehensive audit, planning, strategisation, and implementation help – contacting IntentHarbor would be an ideal move.

One more thing:
If you’re just starting, you don’t need to use or subscribe to multiple SEO tools or platforms right away; a practical approach for the first 3 months would be:

• Use Google Search (SERP) to identify keyword opportunities and associated intent — so your finalised copy provides additional value & guidance.
  
• Monitor performance through Google Search Console once your content is live. Accordingly, make optimisations.
  
• Utilise Google Analytics to see which pages or posts are driving traffic, where your visitors are coming from, and how they interact with your website. These insights can help you improve your content strategy, prioritise high-performing pages, and identify opportunities for location-based pages and local SEO where relevant.
  
• Build internal links between related pages.
  
• Finally, upgrade to tools like Ahrefs, Semrush, or Mangools as your website grows, and your keyword research becomes much more advanced.

Long-Tail Keywords vs Short-Tail Keywords: Which Should You Target?

The practical answer depends on your site’s authority and performance. If you’re a new website, solely targeting short-tail keywords will only add to the noise. You need to target in the ratio of 75:25, where 75% of your content is built around long-tail keywords and the other 25% on short-tail, which becomes your pillar page for clustering & grouping.

Likewise, if you’ve become a brand with notable quality backlinks in your itinerary, targeting short-tail keywords as a query form can be ideal — letting you take on mixed intent fulfillment with next-step guidance.

Together, they can create a stronger topical cluster that benefits both readers and search engines.

Common Keyword Research Mistakes Beginners Should Avoid

• Mistake 1: Choosing keywords based only on search volume
  • Do This Instead: Prioritise keywords that balance search volume, search intent, business relevance, and ranking opportunity.

• Mistake 2: Ignoring search intent
  • Do This Instead: Understand why people are searching before creating content around a keyword.

• Mistake 3: Targeting highly competitive keywords too early
  • Do This Instead: Build authority by starting with relevant long-tail keywords before competing for broader terms.

• Mistake 4: Trying to optimise one page for too many primary keywords
  • Do This Instead: Focus on one primary keyword at a time, and support it with closely related secondary keywords.

• Mistake 5: Skipping keyword evaluation
  • Do This Instead: Assess every keyword for search volume, keyword difficulty, business relevance, search intent, and content fit before making a decision.

• Mistake 6: Relying entirely on keyword research tools
  • Do This Instead: Use tools to validate ideas, but let your audience’s needs guide your strategy.

• Mistake 7: Publishing content without reviewing performance
  • Do This Instead: Regularly monitor your rankings and update your keyword strategy as search behaviour changes.

Remember, avoiding these mistakes doesn’t guarantee first-page rankings, but it does give your content a much stronger foundation. The better your decisions during keyword research, the easier every step that follows becomes.

The IntentHarbor Keyword Research Framework

By now, you’ve learned how keyword research is done, what to keep in mind during this process, and how to organise them into a content strategy. But that’s just the technical side. Successful SEO content isn’t built by just following a checklist alone; it’s built by understanding the people.

At IntentHarbor, this stage is guided by a simple philosophy: rather than chasing search volume alone, we believe every keyword decision should align with your audience’s needs and your business goals

The 5 principles that guide every piece of content we create are:

• Humanity Before Algorithms: Your ultimate audience is humans, not search engines or bots.
• Intent Before Volume: You need to choose keywords based on why people search – and not how many people search.
• Value Before Rankings: Your first focus should be on creating genuinely helpful content. Remember, rankings are the outcome, not the objective.
• Strategy Before Tools: Once you’re clear on your goals and intent, use tools to support your decisions—not to make them for you.
• Consistency Before Shortcuts: Sustainable growth calls for continuous learning, implementation, testing, and refinement—not chasing quick wins or SEO hacks.

Bottom Line

Keyword research for SEO should be aligned to your audience’s needs, business goals, and long-term commitment. After all, it’s only a starting point towards your strategisation & content curation.

As search engines continue to evolve, with AI now dominating the search landscape — maximum visibility and traffic are guaranteed by one thing: providing value & practical help that exceeds the intent of keywords alone.

You can use free and paid tools for keyword research, but let that just be for validating your data and ideas, and not the source of every decision you make.

Heed this: Don’t just create content because a keyword has search volume. Create content because someone is searching for an answer—and you can provide it better than anyone else.
