Keyword research is one of the most important activities in Search Engine Optimization (SEO). It helps digital marketers identify the words and phrases people use in search engines and understand which topics are relevant to their target audience. However, finding keywords is only the first step. Marketers must also evaluate search volume, competition, and keyword difficulty before deciding which keywords to target.
Search volume helps estimate how often people search for a keyword. Competition describes the strength and number of other advertisers or websites competing for visibility, depending on the metric being used. Keyword difficulty estimates how challenging it may be to rank organically for a keyword in search engine results.
These three measurements help marketers compare keyword opportunities and prioritize their SEO activities. A keyword with a high search volume is not always the best choice. A keyword with lower volume but clear intent and manageable competition may attract more relevant visitors and generate better business results.
For example, a digital marketing training provider might consider the broad keyword "digital marketing" and the more specific keyword "digital marketing course for beginners." The broad phrase may reach a wider audience, while the specific phrase may better communicate what a potential learner needs.
After completing this topic, learners will be able to:
Search volume is the estimated number of times a particular keyword or search phrase is searched within a specified period, commonly reported as an average monthly figure for a selected location.
For example, if a keyword research tool reports an estimated monthly search volume of 2,000 for "SEO training," that means the tool estimates approximately 2,000 searches for that term per month in the selected market and period. It does not necessarily mean that 2,000 different people searched for it.
The same person may search for a phrase multiple times. Search volume is therefore different from the number of unique searchers, website visitors, clicks, or conversions.
| Type | Explanation | Example |
|---|---|---|
| Monthly search volume | Estimated searches per month for a keyword in a specified market. | Monthly demand for "SEO course." |
| Average monthly search volume | An average based on a selected historical period, depending on the tool. | Average demand for "digital marketing training." |
| Local search volume | Search demand for a specified geographic area. | "Digital marketing course in Mumbai." |
| Global search volume | Estimated search demand across multiple countries or worldwide, depending on the tool. | "Keyword research tools." |
| Seasonal search volume | Search demand that changes at different times of the year. | Searches for festival-related products. |
A high-volume keyword receives a relatively large number of searches within the selected market and reporting period.
Examples of broad keyword topics:

Challenges:
A low-volume keyword receives relatively few searches within the selected market and period. Such phrases are often more specific, although not every low-volume keyword is a long-tail keyword.

Challenges:
Search volume estimates how often a query is searched. Organic traffic measures visits a website receives from organic search results. A keyword with 10,000 monthly searches does not automatically deliver 10,000 website visits.
Actual traffic depends on factors such as ranking position, whether users click the result, the presence of advertisements and search features, the relevance of the title and description, and the number of searches that lead to the page.
Keyword competition refers to how much competition exists for visibility associated with a particular search term. The meaning depends on whether the marketer is analyzing organic search results or paid search advertising.
In organic SEO, competition analysis involves examining the pages and websites already ranking for a keyword and evaluating how difficult it may be to compete with them. In paid search, competition commonly refers to advertisers bidding on a keyword.
Important distinction: Google Keyword Planner's advertising competition metric relates to competition among advertisers. It should not be treated as a direct measure of organic SEO ranking difficulty.
Organic competition concerns the websites and pages that appear in unpaid search results. Marketers evaluate the quality and relevance of those pages, their backlink profiles, their topical expertise, and how well they satisfy the user's search intent.
For example, the keyword "SEO" may have competition from established educational websites, software providers, agencies, and major publishers. A new website may find it difficult to outperform these pages without strong content, relevance, and overall website quality.
Paid search competition concerns advertisers who want their advertisements to appear for a particular search term. Advertisers may compete through bids, campaign relevance, landing page quality, and the advertising platform's auction process.
Google Keyword Planner may describe paid advertising competition using labels such as low, medium, or high. These labels do not tell a marketer exactly how hard it will be to rank organically.
Keyword Difficulty (KD) is an SEO metric that estimates how challenging it may be for a webpage to rank in organic search results for a particular keyword. SEO tools calculate this metric using their own methodologies, which may include backlink data and other competitive signals.
Many SEO tools display keyword difficulty on a scale from 0 to 100, where a higher score generally indicates greater estimated difficulty. However, there is no universal scoring formula shared by all tools. A score from one platform should not be assumed to mean exactly the same thing as the same score from another platform.
Keyword difficulty is an estimate, not a guarantee. A low score does not guarantee a ranking, and a high score does not mean ranking is impossible.
Keyword difficulty calculations differ across SEO platforms. Some tools place strong emphasis on the backlink profiles of pages ranking in the top search results. Other tools may use additional competitive data or different calculations.
For example, a tool may evaluate the number of unique websites linking to top-ranking pages. If those pages have many strong referring domains, the keyword may receive a higher difficulty score in that tool.
However, a score based heavily on backlinks may not fully reflect content quality, topical relevance, search intent, technical SEO, local factors, or every feature shown on the search results page. Manual review is therefore important.
| Illustrative Score Range | General Interpretation | Possible Strategy |
|---|---|---|
| 0–20 | Relatively low estimated difficulty. | Investigate relevant opportunities and check the actual search results. |
| 21–40 | Low to moderate estimated difficulty. | Consider focused content and strong on-page optimization. |
| 41–60 | Moderate to high estimated difficulty. | Assess competitor quality, backlinks, and website strength carefully. |
| 61–80 | High estimated difficulty. | Plan substantial content, authority development, and long-term SEO work. |
| 81–100 | Very high estimated difficulty. | Evaluate whether the opportunity is worth pursuing and whether the website can compete. |
Note: These ranges are a simplified learning guide, not an official universal standard. Always use the scoring definitions provided by the specific SEO tool you are using.
Keyword difficulty describes the estimated challenge associated with a particular keyword's search results. It does not directly measure the overall quality of your website or guarantee how quickly your page will rank.
The same keyword may be more achievable for an established website with relevant content and strong links than for a new website with little topical coverage. Therefore, always evaluate keyword difficulty in the context of your own website.
| Factor | Search Volume | Competition | Keyword Difficulty |
|---|---|---|---|
| Main meaning | Estimated frequency of searches. | Strength or level of competing advertisers or organic competitors, depending on the metric. | Estimated challenge of ranking organically. |
| Main question | How often is this keyword searched? | Who else is competing for visibility? | How difficult may organic ranking be? |
| Common measurement | Average monthly searches or a range. | Competitor analysis or an advertising competition label. | Tool-specific score or qualitative estimate. |
| Typical source | Keyword research tools. | Search results and advertising research tools. | SEO keyword difficulty tools and manual analysis. |
| Primary use | Estimate search demand. | Understand the competitive environment. | Estimate ranking challenges. |
| What it does not guarantee | Actual website traffic. | Organic ranking difficulty when the metric refers to paid ads. | A specific ranking position or time to rank. |
These metrics should be considered together with keyword relevance, search intent, business value, and the quality of the content you can produce.
Search volume and keyword difficulty help marketers compare opportunities, but neither metric should be used alone.
A useful keyword is not necessarily the keyword with the largest volume or the lowest difficulty. It is a keyword that attracts a suitable audience, matches the page's purpose, and supports the website's objectives.
Decide what you want the website to achieve. Goals might include increasing brand awareness, attracting organic visitors, generating enquiries, selling products, or encouraging course registrations.
Seed keywords are broad starting terms that represent your products, services, or subject area.
Example for a digital marketing training provider:
Use keyword tools, search suggestions, related searches, and customer questions to find more specific phrases.
Enter your keywords into a keyword research tool. Select the relevant country or location and note the reported search volume and reporting period. Remember that the data is an estimate and may differ between platforms.
Examine the search results for each keyword. Identify the competing websites, the content types they publish, and how well they satisfy the search intent.
Use an SEO tool to obtain a difficulty estimate. Compare scores within the same platform and examine the underlying search results rather than relying on the score alone.
Classify the keyword as informational, navigational, commercial investigation, or transactional where appropriate. Choose a page format that answers the user's likely need.
Ask whether ranking for the keyword would help your target audience and support your business. A high-volume keyword that attracts irrelevant visitors may have little practical value.
Assign each main keyword or closely related keyword group to a suitable page. Avoid creating multiple pages that compete for the same search intent unless there is a clear reason to separate them.
After publishing or optimizing content, monitor impressions, clicks, CTR, rankings, organic sessions, enquiries, and conversions. Use these results to update the content and refine your keyword priorities.
| Tool | Primary Purpose | Useful Information |
|---|---|---|
| Google Keyword Planner | Keyword and advertising research. | Search-volume estimates, related keyword ideas, and paid advertising competition information. |
| Google Search Console | Monitor a verified website's organic performance. | Queries, impressions, clicks, CTR, and average position. |
| Google Trends | Explore interest patterns over time. | Relative search interest, comparisons, and seasonal patterns. |
| Ahrefs | SEO and competitor research. | Keyword ideas, estimated difficulty, backlinks, and competitor analysis. |
| Semrush | Keyword and SEO analysis. | Keyword research, difficulty estimates, competitor information, and tracking features. |
| Google Search suggestions | Discover query variations. | Suggested phrases and common ways users formulate searches. |
Tool features, data coverage, and pricing may vary. Free tools can be sufficient for basic research, while paid platforms may offer more extensive competitive analysis.
Suppose a digital marketing training website wants to attract learners interested in SEO and digital marketing courses. The marketer creates a keyword evaluation table to compare potential opportunities.
| Keyword | Search Volume | Competition or Difficulty | Possible Content |
|---|---|---|---|
| Digital marketing | To be researched | To be researched | Broad educational guide or category page. |
| Digital marketing course for beginners | To be researched | To be researched | Beginner-focused course page. |
| How to do keyword research | To be researched | To be researched | Step-by-step SEO tutorial. |
| Keyword research tools for small businesses | To be researched | To be researched | Tool comparison and practical guide. |
| Digital marketing course in Mumbai | To be researched | To be researched | Relevant local course page, if the service is offered there. |
The table deliberately leaves metrics blank because search volume and difficulty should be verified for the target market using a current keyword research tool. Do not treat illustrative keyword examples as actual search-volume or difficulty data.
Imagine two keywords have these hypothetical values:
| Metric | Keyword A | Keyword B |
|---|---|---|
| Keyword | Digital marketing | Digital marketing course for beginners |
| Monthly search volume | 10,000 | 700 |
| Illustrative difficulty score | 85 | 25 |
| Intent | Broad and potentially mixed. | More specific learning or course intent. |
| Possible priority | Long-term strategic target. | Potentially useful focused target. |
Note: The numbers above are fictional and used only to demonstrate the evaluation process.
Keyword A has more estimated searches, but it may be harder to rank for and may attract a broader audience. Keyword B has fewer searches but may be more relevant to a page designed for beginners. A sensible strategy could include both, with priorities determined by actual data and business goals.
Search intent is the reason a person enters a query into a search engine. It is an essential part of keyword analysis because volume and difficulty alone do not explain what content users expect.
| Intent Type | Example Keyword | Suitable Content |
|---|---|---|
| Informational | What is keyword difficulty? | Educational article or guide. |
| Navigational | JustAcademy digital marketing course | Official course page. |
| Commercial investigation | Best digital marketing courses for beginners | Comparison or course information page. |
| Transactional | Register for digital marketing course demo | Registration or conversion page. |
Review the search results to understand the dominant intent. If the results mainly show detailed guides, a sales-focused landing page may not satisfy users. Similarly, a user looking to register may prefer a clear course page or registration form rather than a broad educational article.
| Mistake | Why It Matters | Recommended Action |
|---|---|---|
| Choosing only high-volume keywords | High demand does not guarantee relevant traffic. | Evaluate intent, competition, and business relevance. |
| Confusing paid competition with SEO difficulty | Advertising competition and organic ranking difficulty measure different things. | Check the metric's definition in the tool. |
| Trusting one difficulty score completely | Tool formulas and data sources vary. | Compare tool estimates with manual SERP analysis. |
| Ignoring geographic targeting | Search demand and competitors differ by location. | Choose the correct market and language. |
| Assuming low volume means no value | Specific queries can attract relevant visitors. | Consider audience relevance and business potential. |
| Ignoring search intent | The page may not answer what users want. | Match the content type to the search query. |
| Creating pages only for keywords | Thin or repetitive pages may not provide value. | Create original, helpful content for real user needs. |
| Never reviewing keyword performance | Search demand and competitive results can change. | Review performance periodically and update content. |
Keyword research does not end when a page is published. Marketers should measure performance to determine whether the chosen keywords are helping the website achieve its goals.
CTR formula:
CTR = (Clicks / Impressions) × 100
Example: If a page receives 1,000 impressions and 40 clicks, its CTR is (40 / 1,000) × 100 = 4%.
Use Google Search Console to understand search performance and an analytics platform to examine on-site activity and conversions. Interpret results in context because rankings, search features, seasonality, and changes in user behavior can affect performance.
Answer: Search volume is the estimated number of times a keyword is searched within a specific period, commonly reported as an average monthly figure for a selected market.
Answer: Keyword competition describes the level or strength of competing advertisers or organic websites. Its meaning depends on the metric and tool being used.
Answer: Keyword difficulty is an SEO metric that estimates how challenging it may be to rank organically for a particular keyword.
Answer: Search volume estimates how often a query is searched, while keyword difficulty estimates how hard it may be to rank for that query in organic results.
Answer: No. Paid advertising competition refers to advertiser activity, whereas keyword difficulty generally estimates organic ranking challenges. Some tools use the word "competition" more broadly, so the metric definition should always be checked.
Answer: No. Actual traffic depends on ranking position, click-through rate, search result features, search intent, and whether users click the website's result.
Answer: Yes. A low-volume keyword can be valuable when it attracts a relevant audience and supports a meaningful business goal.
Answer: Methods vary. Some tools place strong emphasis on backlinks to top-ranking pages, while others use different combinations of competitive data. Difficulty scores should be interpreted according to the tool's methodology.
Answer: Google Keyword Planner, Google Search Console, Google Trends, Ahrefs, Semrush, and search suggestions can support different parts of keyword research.
Answer: Start with relevant keywords, check search intent, estimate volume, review competition and difficulty, and choose a page topic that the website can address well.
Answer: Search intent helps marketers understand what users want and create content that satisfies their needs. A keyword with good search volume may still perform poorly if the page does not match the intent.
Answer: Use impressions, clicks, CTR, average position, organic sessions, engagement, and conversions. The most important measures depend on the website's goals.
Explain what each metric tells you for the keyword "digital marketing course for beginners":
Select five keywords related to a business or industry of your choice. Research their estimated search volume and difficulty using a keyword tool. Record the target country and date of research.
Create a table with these columns:
Search for three keywords and review the first page of results. Identify the main page types, common topics, competing websites, and potential content gaps. Write a short recommendation explaining which keyword is most suitable for your website and why.
Choose one main keyword and three to five closely related supporting terms. Decide which page should target the main topic, what questions the content should answer, and how you will measure success.
Understanding search volume, competition, and keyword difficulty is essential for building an effective SEO strategy. Search volume estimates demand, competition analysis helps marketers understand the websites or advertisers they are competing against, and keyword difficulty estimates the challenge of achieving organic rankings.
These metrics should be evaluated together with search intent, relevance, business value, and the quality of the competing search results. A keyword with lower volume may be more useful than a broad, highly competitive keyword when it attracts the right audience and supports a clear objective.
Successful keyword research requires consistent analysis, helpful content, appropriate page optimization, and ongoing performance measurement. Keyword tools can guide decisions, but their estimates should always be checked against real search results and website performance.
