Finding and analyzing the words and phrases individuals type into search engines while seeking information, goods, or services is known as keyword research. In SEO, it helps you understand what your audience searches for, how much demand exists for a topic, and which search terms are realistic to target. Good keyword research gives your content a clear subject and helps you create pages that answer real search queries.
If you publish content without knowing what people search for, you may spend time writing about topics that receive little search demand. Before you begin writing, you can make smarter selections by conducting keyword research.
What Is Keyword Research?
Keyword research is the process of discovering search terms that relate to your website, audience, or business and then evaluating which ones are worth targeting.
A keyword can be a single word, like SEO, or a larger phrase, such as what content marketing is or how SEO operates. People use these phrases to find answers, compare options, solve problems, and make decisions.
Let’s take an example where you wish to produce an article regarding SEO. You could just write a post titled “SEO Guide.” Researching keywords may reveal more focused queries like:
- What is SEO?
- How does SEO work?
- Why is SEO important?
- What is keyword research?
- How to do keyword research
These searches give you a better idea of the questions people want answered.
Comparing data like search volume, term difficulty, and search intent is another aspect of keyword research. Tools such as Semrush Keyword Overview provide these types of data to help you compare keyword opportunities.
What Is Keyword Research in SEO?
You can choose the subjects and search terms that your website should focus on by conducting keyword research.
Search engines must comprehend the purpose of a page. Google recommends using words that people would use to find your content in places such as the page title, main heading, and descriptive link text.
For example, if you are writing about SEO keyword research, terms related to that topic can appear naturally in:
- The page title
- The main heading
- Subheadings
- Body text
- Image alt text where appropriate
- Internal links
This does not imply using the same keyword as frequently as you can. Google says its language systems can understand how a page relates to different searches without requiring every variation to appear as an exact phrase.
The goal is to create a useful page that clearly answers the searcher’s question.
What Is Keyword Research and Analysis in SEO?
Although they are related, keyword research and analysis are not the same.
Keyword research involves finding potential search terms. You may find dozens or hundreds of similar keywords by starting with a wide topic.
Keyword analysis involves evaluating those keywords to decide which ones are worth targeting.
You might compare:
- Search volume
- Keyword difficulty
- Search intent
- Relevance to your audience
- Competition
- The type of content already ranking
Assume, for instance, that you wish to write about SEO.
Although there is a lot of demand for the term “SEO,” it is very wide. A more focused search, such “how does SEO work,” reveals a lot more about the person’s preferences.
The keyword with the largest search traffic isn’t always the best one for an article. It should match the topic you can cover well and the information the searcher expects to find.
Why Is Keyword Research Important?
Making content decisions based on real search activity rather than conjecture is made easier using keyword research.
It helps you understand what people search for
A topic can sound useful to you without being something your audience searches for.
You may get information about the terms people use by conducting keyword research. For instance, one person interested in SEO would look up “what is SEO,” while another might look up “how does SEO work.”
You can produce content that addresses particular topics by being aware of these distinctions.
It helps you choose better content topics
Keyword research can turn a broad subject into specific article ideas.
Suppose your website covers content marketing. Instead of publishing another general article about content marketing, keyword research could lead you toward topics such as:
- What is a content marketing strategy?
- What is a content marketing plan?
- Types of content marketing
- Content marketing vs digital marketing
Each search represents a different question or information need.
It helps you understand search intent
What a person desires when they type a query into a search engine is known as search intent.
The purpose of a search like “what is keyword research” is to find information. The person wants an explanation.
The “best keyword research tool” search is not the same. The individual may be getting closer to making a choice as they compare tools.
Selecting the appropriate format for your information is made easier when you are aware of this distinction. An informational keyword may call for a guide or explanation, while a comparison query may need a list, review, or comparison page.
It helps you evaluate competition
The difficulty of ranking for a search query can be demonstrated using keyword research tools.
Semrush, for example, uses a Keyword Difficulty (KD%) score from 0 to 100. A higher score indicates that ranking in the top results is likely to be more difficult. Semrush also notes that its KD score is an estimate created by the tool, not a Google ranking metric.
When choosing between related keywords, this can be helpful.
A new website may find it difficult to compete immediately for a highly competitive keyword. A more specific keyword with lower competition may offer a more realistic starting point.
It helps you plan related content
You can create a collection of linked articles with the use of keyword research.
For example, a website covering SEO could have separate articles about:
- What is SEO?
- How does SEO work?
- What is keyword research?
- How to do keyword research
- What is search intent?
- What is SEO vs SEM?
These pages can cover different questions while remaining connected to the same subject area.
What Is the Relationship Between Keywords and Keyword Research?
A keyword is the word or phrase someone enters into a search engine. Keyword research is the process of finding and evaluating those search terms.
For example, “content marketing strategy” is a keyword.
Researching that keyword might involve checking its search volume, difficulty, intent, related searches, and the pages currently appearing in Google.
The keyword is the search term. Keyword research is the process used to understand that search term and decide whether it is suitable for your content.
What Factors Should You Consider When Choosing Keywords?
Search volume and keyword difficulty are useful, but they are not the only things to consider.
Search volume
Search volume estimates how often people search for a keyword during a given period. Semrush describes it as an estimate of the average monthly searches for a keyword.
A keyword with higher volume can have more traffic potential, but high volume does not guarantee traffic to your website.
Keyword difficulty
Keyword difficulty estimates how hard it may be to rank for a keyword. Higher difficulty generally means stronger competition from existing pages.
Search intent
Ask what the person actually wants to find.
If the keyword is “what is keyword research,” an introductory explanation is appropriate. If the keyword is “best keyword research tools,” readers may expect comparisons and recommendations.
Relevance
The keyword should make sense for your website and audience.
A keyword with thousands of searches is not useful if it has little connection to what you publish.
The current search results
Look at the pages already ranking for the keyword. This can tell you whether Google is showing beginner guides, product pages, comparison articles, videos, or other formats.
The existing results can help you understand what type of content searchers expect.
How to Do Keyword Research
You can follow a simple process when researching keywords for a new article.
1. Start with a topic.
Choose a subject related to your website.
2. Find related search terms.
Use a keyword research tool to discover variations, questions, and related phrases. Semrush’s keyword research tools provide keyword suggestions along with metrics such as search volume, difficulty, and intent.
3. Check the numbers.
Compare search volume and keyword difficulty. Don’t automatically choose the keyword with the largest volume.
4. Identify the search intent.
Determine what the searcher wants to accomplish.
5. Review the search results.
Search the keyword yourself and examine the pages Google currently ranks.
6. Choose a primary keyword and related terms.
Select one main topic for the page and use closely related terms where they make sense.
Google’s Keyword Planner can also generate keyword ideas and provide estimates of monthly searches. It is designed primarily for Google Ads, so SEO-focused research tools may provide different metrics and data.
What Is a Keyword Research Tool?
A keyword research tool is software that helps you find and evaluate search terms.
Depending on the tool, you may see information such as:
- Monthly search volume
- Keyword difficulty
- Search intent
- Related keywords
- Competition
- Cost per click
- Search results
Semrush’s keyword research tools can generate keyword ideas and provide data that helps you compare potential targets.
Google also provides Keyword Planner, which can help users discover keyword ideas and view estimates for searches and advertising costs.
You do not need to use every available metric. Start with the information that helps you decide whether a keyword is relevant, useful, and realistic for your website.
Common Keyword Research Mistakes
A few mistakes can make keyword research less useful.
Choosing volume over relevance: A high-volume keyword is not automatically the right keyword for your website.
Ignoring search intent: A page may fail to satisfy searchers if it does not answer the question behind the query.
Targeting only broad keywords: Specific searches can give you clearer topics and may have less competition.
Keyword stuffing: Repeating a keyword excessively can make an article difficult to read. Use keywords where they accurately describe the content.
Ignoring the existing results: The pages ranking for a query provide useful information about the type of content Google currently considers relevant.
Google recommends creating helpful, reliable, people-first content rather than producing pages mainly to attract search-engine traffic.
