Keyword research is the foundation of every successful SEO strategy. Without it, you’re guessing — publishing content and hoping the right people find it. With it, you know exactly what your audience is searching for, which terms you can realistically rank for, and what topics to prioritize.
This guide walks you through keyword research from scratch. By the end, you’ll have a repeatable process for finding keywords that actually drive traffic.
Why Keyword Research Matters
Every piece of content you create should target a specific search query. Keyword research tells you:
- What people are searching for — the exact language they use, not what you assume they use
- How often they search for it — search volume
- How hard it will be to rank — keyword difficulty
- What they’re trying to accomplish — search intent
Skipping keyword research means you might write a brilliant article that nobody ever finds. Doing it well means your content reaches people at the exact moment they’re looking for what you offer.
Step 1: Understand Search Intent
Before you start pulling keyword data, you need to understand search intent — the reason behind a search query. Google’s primary job is to match queries with results that satisfy user intent. If your content doesn’t match the intent, you won’t rank, regardless of how well optimized it is.
The four main types of search intent:
- Informational — the user wants to learn something. “How does SEO work,” “what is keyword research.”
- Navigational — the user is trying to reach a specific website or page. “Ahrefs login,” “Google Search Console.”
- Commercial investigation — the user is researching before making a decision. “Best SEO tools 2026,” “Ahrefs vs Semrush.”
- Transactional — the user wants to take an action (buy, sign up, download). “Buy SEO audit tool,” “SEO tool free trial.”
To determine intent for any keyword, Google the term and look at what’s already ranking. If the top results are all blog posts, your content should be a blog post. If they’re product pages, informational content won’t rank for that term.
Step 2: Generate Seed Keywords
Seed keywords are broad, short terms that describe your topic area. You’ll use them to generate hundreds of more specific keyword ideas.
Start by brainstorming the core topics your website covers. For an SEO blog, seeds might be: “keyword research,” “link building,” “technical seo,” “on-page seo,” “content strategy.”
Write down every relevant topic you can think of, then think about what problems your audience has and what questions they ask. Talk to customers, check your email inbox, look at support tickets — real language from real people is gold for seed keywords.
Step 3: Expand with Free Keyword Tools
Google Keyword Planner
Google Keyword Planner is free with a Google Ads account and provides search volume data directly from Google. Enter your seed keywords and it generates hundreds of related keyword ideas with monthly search volume ranges.
Note that the free version shows volume ranges (like “1K–10K”) rather than exact numbers. Paid tools give you precise figures, but the Planner is a solid starting point with no cost.
Google Suggest (Autocomplete)
Type any seed keyword into Google and watch what autocomplete suggests. These suggestions come directly from real searches by real users — they’re some of the most reliable keyword ideas available.
Also scroll to the bottom of any search results page for the “Related searches” section. These are more query variations Google considers relevant to your original search.
Google Search Console
If your site already has traffic, Google Search Console is a treasure trove of keyword data. Navigate to Performance > Search Results to see exactly which queries people are already using to find your pages. You’ll often discover keywords you’re ranking for in positions 10–30 that, with targeted optimization, you could push to page one.
Answer The Public and AlsoAsked
These tools visualize the questions people ask around any topic, pulling from Google’s “People Also Ask” data. Excellent for finding long-form content ideas and FAQ topics.
Step 4: Analyze Keyword Difficulty
Not every keyword is worth targeting. Head terms like “SEO” get millions of searches per month — but they’re dominated by massive, high-authority domains. A new site trying to rank for “SEO” is wasting its time.
Keyword difficulty (KD) is a score (usually 0–100) that estimates how hard it will be to rank in the top 10 for a given keyword. Most paid tools (Ahrefs, Semrush, Moz) provide this metric.
General guidance:
- KD 0–20: Low competition, suitable for new sites
- KD 21–50: Moderate competition, achievable with solid content and some links
- KD 51–80: High competition, requires domain authority and strong backlink profile
- KD 80+: Very difficult, typically dominated by major brands
If your site is new, focus almost entirely on low-difficulty keywords. You’ll rank faster, build domain authority, and gradually expand into more competitive terms.
Step 5: Understand Head Terms vs. Long-Tail Keywords
Head terms are short, broad keywords (1–2 words). High search volume, high competition, vague intent. Example: “keyword research.”
Long-tail keywords are longer, more specific phrases (3–5+ words). Lower search volume, lower competition, much clearer intent. Example: “how to do keyword research for a new blog.”
For most websites — especially new ones — long-tail keywords should make up the bulk of your content strategy. They’re easier to rank for, and because they’re so specific, they often convert better too. We cover this strategy in detail in our guide to long-tail keywords.
Step 6: Build a Keyword Priority List
With your keyword ideas collected and analyzed, it’s time to prioritize. Score each keyword on three factors:
- Search volume — is there enough traffic to justify the effort?
- Keyword difficulty — can you realistically rank for it given your site’s authority?
- Business relevance — if you rank for this keyword, will it bring the right audience?
Create a spreadsheet with these three columns and rate each keyword. Prioritize keywords that score well on all three — high relevance, decent volume, and low enough difficulty that you can compete.
Then map keywords to content. Each piece of content should target one primary keyword and a handful of closely related secondary keywords.
Great keyword research is the foundation everything else is built on. Once you have your priority list, read our guide on keyword difficulty to understand how to evaluate competition more precisely before committing to a topic.
