Keyword Research: find what people search
Keyword research is the foundation of every successful SEO strategy. Learn how to find the right keywords, understand search intent, and build a keyword strategy that drives qualified traffic to your site.
Types of keywords
Not all keywords are created equal. Understanding the three main types helps you build a balanced strategy.
Head Keywords
Short, broad terms with high search volume. Very competitive and hard to rank for. Example: "running shoes"
Body Keywords
2-3 word phrases with moderate volume and competition. Good balance of traffic and feasibility. Example: "best running shoes"
Long-Tail Keywords
4+ word phrases with lower volume but high intent and conversion rates. Easier to rank for. Example: "best running shoes for flat feet"
Understanding search intent
Every search has a purpose. Match your content to what the user actually wants, and Google will reward you.
Informational
User wants to learn something. They are at the top of the funnel, researching a topic.
"what is seo" "how to do keyword research" "seo meaning" Navigational
User is looking for a specific website or page. They know where they want to go.
"seomate tools" "google search console" "ahrefs login" Commercial
User is researching before making a purchase. They are comparing options and reading reviews.
"best seo tools 2026" "semrush vs ahrefs" "free seo tools review" Transactional
User is ready to buy or take action. High conversion intent at the bottom of the funnel.
"buy seo tool" "hire seo consultant" "seo audit service" Key keyword metrics to track
These six metrics help you evaluate and prioritize which keywords to target first.
Search Volume
How many times per month people search for this keyword. Higher volume means more potential traffic — but also more competition.
Keyword Difficulty
How hard it is to rank for this keyword. Based on the authority of pages currently ranking. Lower difficulty means easier to rank.
Cost Per Click (CPC)
What advertisers pay per click in Google Ads. High CPC indicates commercial value and buying intent for that keyword.
Search Intent
Why the user is searching. Understanding intent ensures you create the right type of content for each keyword.
Trend
Whether search volume is growing, stable, or declining over time. Rising trends mean opportunity; declining trends mean danger.
SERP Features
What special features appear in search results — featured snippets, People Also Ask, image packs, videos. These create additional ranking opportunities.

Keyword research FAQ
Answers to the most common questions about keyword research for SEO.
What is keyword research in SEO?
Keyword research is the process of finding and analyzing the search terms that people enter into search engines. The goal is to identify keywords with good search volume, manageable competition, and relevant intent that you can create content around to drive organic traffic.
How many keywords should I target?
Focus on one primary keyword per page, plus 3-5 secondary/related keywords. For a new site, start with 20-30 target keywords across your key pages. Quality over quantity — well-optimized pages targeting the right keywords outperform thin pages targeting many keywords.
What is a good keyword difficulty score?
For new or low-authority sites, target keywords with difficulty under 20-30. As your domain authority grows, you can target more competitive keywords. Always check the actual pages ranking — if small sites rank, you can too, regardless of the difficulty score.
Should I target short-tail or long-tail keywords?
Both, but prioritize long-tail keywords first. They are easier to rank for, have clearer intent, and convert better. As your site builds authority, gradually target more competitive head terms. A healthy keyword portfolio has a mix of both.
Can I do keyword research for free?
Yes. Google Keyword Planner, Google Trends, Google Autocomplete, Google Related Searches, and Google Search Console are all free and provide excellent data. SEOMate also offers a free Keyword Density Checker to verify your content optimization.
