How to Do Keyword Research for SEO (Beginner-Friendly Guide)

Imagine you have a website about indoor plants, but when someone types “best indoor plants” into Google, your site doesn’t show up. 

Many Search Engine Optimization (SEO) factors can affect ranking, and one of the most important is keyword research. 

Doing proper keyword research and naturally including the right keywords in your content can help you: 

In this guide, you’ll learn how to do keyword research step by step with real examples, free tools, and strategies that work even if you’re just getting started. 

Before you begin, please read our blog on SEO basics to ensure you understand the fundamentals before starting keyword research.  

What is Keyword Research?  

Keyword research in SEO involves identifying the most relevant words or phrases that user enter into search engines, such as Google, when seeking information.   

Suppose you want to buy a red bicycle, you might type 

“Buy a red bicycle for kids” on Google. This full phrase is a keyword.  

There are various types of user queries. Some users may want to purchase something, as shown in the example above, while others may seek information about something.  

Benefits of Keyword Research 

Effective keyword research and optimization boost SEO performance, attracts targeted traffic, strengthens content strategy, and enhances user experience.    

When you start using tools like Google Keyword Planner, Ubersuggest, or Answer the Public, they show you real search terms people are typing into Google. 

These terms reflect problems, questions, and goals your audience has, not what you think they care about, but what they actually want to know. 

Let's understand it with an example. 

By targeting keywords with proven search volume, you ensure that your blog post, video, or product page is solving a customer's need. 

Keywords help you structure your content. They guide you what to include, what questions to answer, and what angle to take. 

Instead of writing a general article on "gardening tips," you create focused content on "how to water succulents without overwatering." That’s a real problem people are searching for.   

When you use the right keywords in your content title, headers, meta description, and first paragraph search engines recognize your page as relevant to that topic. 

This increases the chance of your content appearing on Google’s first page, or even in a featured snippet (like an answer box). 

If your article uses the keyword "why are my plant leaves turning yellow?", Google is more likely to show your article to someone typing that exact question. 

Keyword research helps you align content with intent, meaning whether someone is just browsing (informational), comparing options (navigational), or ready to buy (transactional). 

When you match your content to their intent, people stay longer, trust your content more, and are more likely to take action (subscribe, buy, contact you). 

Targeting "best indoor plants for low light" attracts buyers who are probably looking to purchase plants, not just learn about them. 

Keyword research can reveal new terms or phrasing people are using, which might not have been relevant when your article was first published. 

You can refresh your content by adding these terms, answering new questions, and updating information, boosting your search visibility without creating new content. 

An old article titled "Top Office Plants" might be updated with keywords like "best indoor plants for productivity" or "pet-friendly desk plants" based on current search trends. 

Keyword trends show rising topics, seasonal interests, and shifting consumer priorities. 

You can use this data to guide campaigns, product launches, and content calendars, focusing your time and budget where it matters most. 

If keyword volume for "grow your own food" spikes in spring, you can plan a product bundle or video series around that trend.

How to do Keyword Research?  

1. Get clear on what your topic or niche is all about. 

Start by defining the main subject of your website or content. This is your niche.  

Always think: 

2. Come up with keyword ideas your audience might search for. 

Think about what real people type into a search engine like Google when they need help or answers.

Example entities: 

3. Use free tools to explore real keyword data 

Find real data, search volume, competitor gaps, and related terms using keyword research tools.

4. Check how often people search and how hard it is to rank 

When you find keywords and related terms using tools and research, always consider two key metrics.  

1. Search volume (monthly search volume of the keyword) 
2. Keyword difficulty (KD) (how hard it is to rank on the search engine first page) 

If your keyword has low search volume, it may reach fewer people. Keywords with high search volume and keyword difficulty (KD) are harder to rank for. Always consider both search volume (SV) and KD when optimizing keywords in your content. 

Here is the simple strategy you can use: 

• Find high search volume with low difficulty keywords. 
• Use all keyword variations like easy-win and medium-competitive terms. 

Example: 

• “puppy training” (high volume, high competition) 
• “How to train a 3-month-old puppy to stop biting” (lower volume, less competition) 

5. Focus on specific, long-tail keyword phrases 

Try to use long-tail keywords in content as they are more specific. They match exactly what people are asking.  

Using long keywords gives you numerous advantages:  

Examples 

6. See what keywords your competitors are ranking for. 

Spy on your competitor's website. Go to Google, search your keyword, and check the top-ranking pages. Copy their URL and paste it into the SEO tools like:  

List the keywords your competitors are ranking for, understand the user intent behind them, and optimize your on-page SEO to outperform them. 

Look for basic On-Page: 

7. Naturally, include keywords in your content where they make sense 

Place your keywords where they matter without stuffing: 

Example: 

Instead of writing: 

“dog training dog training dog training” 

Write: 

“Training your dog—especially a young puppy—can be fun and effective with positive reinforcement techniques.”
