How to Do Keyword Research for SEO: A Complete Beginnerâs Guide
What Is Keyword Research?
Keyword research is the process of identifying and evaluating the specific words and phrases (known as âkeywordsâ) that people enter into search engines such as Google, Bing, or YouTube while looking for information, products, or services. Keyword research in SEO is the cornerstone for developing content and advertisements that attract the correct audience and deliver genuine results in digital marketing, particularly SEO (Search Engine Optimization) and PPC (Pay-Per-Click).
Building an SEO Keyword Strategy That Works
Developing an SEO keyword strategy is the process of determining which keywords to target and prioritise in organic search. There are numerous approaches, but they all boil down to identifying terms that:
There are numerous approaches, but they all boil down to identifying terms that:
Potential customers are looking for something.
Create value for your business.
Are in your wheelhouse to rank for.
Identify keywords with traffic potential.
Targeting keywords that no one types into Google is pointless since they will not get you traffic even if you rank first. The first step is to identify keywords that potential clients are searching for.
See which of your competitorsâ pages get the most traffic
Targeting keywords that no one types into Google is pointless since they will not get you traffic even if you rank first. The first step in SEO keyword analysis is to identify keywords that potential clients are searching for.
Hereâs how you may determine which of your competitorsâ pages receive the most search traffic:
Go to Semrush Domain Overview
Enter a competitorâs domain
Go to the Top pages report

Keyword research tools such as SEMrush provide extensive keyword databases that can be searched and filtered.
Hereâs how you can utilize SEMrushâs Keyword Magic Tool to identify keywords with high traffic potential:
Go to SEMrush Dashboard and activate the Keyword Magic Tool.
Enter a few broad keywords associated with your niche (these are your âseedâ keywords).
Use filters like search volume, keyword difficulty, and CPC to narrow down the results.
Look for terms that have high traffic potential and business intent.
Checking Keyword Value for Your Business
Each keyword that potential clients search for has some worth for your company. However, some offer greater business potential than others.
Consider these three keywords, for instance:
âSports shoesâ â Searchers are browsing. They are considering their choices but have not made a decision.
ârunning shoes vs training shoesâ â Searchers compare. Theyâve limited their options and are almost ready to make a buy.
âNivia football shoes size 9â â The searcher knows exactly what they want. Theyâre ready to buy right now.
Given that some of these people are more likely to purchase sports equipment than others, it makes logical to favour this kind of SEO keyword analysis with strong commercial intent and business potential.
These are the ones that are more likely to result in a sale and should be a main component of your SEO keyword strategy, much as a brand like Decathlon could optimize their product pages.
How Backlinks Affect Keyword Ranking Difficulty
There are several reasons why keyword ranking difficulty varies. This is not to say that you should avoid keywords that are more difficult to rank for, but it is crucial to consider ranking difficulty while developing your keyword strategy.
Backlinks are one of Googleâs primary ranking factors. The current top-ranking pages have more high-quality backlinks, making it more difficult to compete with them.
The Keyword Difficulty (KD) score in SEMrushâs Keyword Overview tool will help you estimate how many backlinks youâll need to get into the top ten. This score considers the backlink strength of pages currently ranking for the term. Scroll down to the SERP Analysis section for a more detailed examination. The âRef. Domainsâ (referred domains) column shows how many unique websites link to each ranking page.
Keep in mind that these metrics represent the amount of backlinks, not their quality. To evaluate link quality, click on the backlink numbers to view each pageâs backlink profile using SEMrush Backlink Analytics. Look for authoritative domains, contextual links, and follow vs. nofollow ratios to determine genuine link strength.

Google personnel have repeatedly said that Google does not consider a siteâs authority. However, there are a few ways in which a siteâs so-called authority may indirectly influence rankings.
Internal links â High-DR sites have more high-authority pages, which can help other pages rank higher.
Familiar brands â For certain inquiries, searchers are inclined to look for familiar names. If that is not you, you may have a more difficult time ranking.
If you believe Google considers site authority, or you simply want to be cautious, check the DR ratings of the top-ranking pages in Keywords Explorer. If theyâre all significantly higher than your siteâs DR, consider prioritizing different keywords.
To have any chance of ranking for this keyword, you must create a free tool. Unless you have a backlink database like ours, this will be nearly difficult. As a result, we propose studying the top-ranked results for the three Cs of search intent to determine the difficulty of ranking a keyword for you.
Content type:Â Are they blog entries, landing pages, product pages, or something else?
Content format:Â Are they listicles, how-tos, recipes, tools, or something else?
Content aspect â Is there a main selling point, such as how easy it is?

Compare this to the top results for numerous other queries that provide no information about how recommendations were selected. It will likely be considerably easier to outperform these in terms of content quality than the former. Based on your assessment of the four criteria listed above, you can assign keywords a âranking potentialâ score as follows:
Use SEMrushâs Keyword Magic Tool and Keyword Overview to collect and export the following information:
Keyword
Search Volume (To Estimate Traffic Potential)
Keyword Difficulty (KD) (to determine ranking potential)
Business Potential (BP) (assign this based on how relevant or profitable the keyword is for your product/service)
To make your spreadsheet even more efficient, use conditional formatting to highlight
Keywords with high volume and low difficulty (green).
Medium priority or competitive terms (yellow)
Terms with low value or that are irrelevant (in red)

This helps identify keywords with real search demand for your SEO keyword strategy.

Open the SEMrush Dashboard and activate the Keyword Magic Tool. Enter broad seed keywords related to your niche, then use filters like search volume, keyword difficulty, and CPC to find high-traffic keywords with business intent.
