What is keyword research in SEO?

Keyword research is the process of discovering and evaluating the search terms people use, then choosing which ones your pages should target. It's the foundation of every successful SEO strategy.

How many keywords should one page target?

One primary keyword and 3–8 closely related secondary keywords. Targeting too many forces compromises that hurt ranking for all of them.

Is keyword density still a ranking factor?

No. Google has used semantic understanding for over a decade. Write naturally, cover the topic thoroughly, and skip the 1–2% keyword density rules from 2010. Use our keyword density tool only as a quick sanity check for accidental stuffing.

How do I find low-competition SEO keywords?

Filter for keyword difficulty under 30, then read the actual top-10 results. If they're all weak (thin content, low authority, no schema), the real-world competition is lower than the score suggests.

Should I target high-volume keywords as a new site?

Usually no. Start with long-tail keywords (KD < 30, volume 100–1,000) and build authority. After 6–12 months you can credibly chase higher-volume terms.

Keyword Research for Beginners: A Step-by-Step SEO Guide

What is keyword research?

Keyword research is the process of finding the words and phrases people type into search engines, then deciding which ones are worth targeting with your content. It's the single highest-leverage SEO activity for a new site — get it right and every post you publish has a path to ranking. Get it wrong and you'll spend a year writing for queries no one searches.

The 4 types of search intent

Before chasing volume, classify intent. Google ranks pages that match intent — a brilliant guide can't outrank a basic product page for "buy X" because the intent is wrong.

Informational — "what is seo", "how to bake bread". Answer with a guide or blog post.
Navigational — "facebook login", "nike running". User wants a specific site.
Commercial investigation — "best CRM for small business", "iphone vs samsung". Answer with comparisons, reviews.
Transactional — "buy iphone 15", "asana pricing". Answer with product/pricing pages.

The 4 metrics that actually matter

Search volume — monthly searches. Under 100 = niche, 100–1K = small, 1K–10K = solid, 10K+ = high demand.
Keyword difficulty (KD) — 0–100. New sites should target KD < 30 to start.
Cost per click (CPC) — what advertisers pay. High CPC = commercially valuable, not just popular.
SERP features — featured snippets, AI overviews, image packs. They shape how much organic clicks remain.

The 5-step process

1. Brainstorm seed keywords

List 5–10 phrases your ideal customer would search. Don't worry about volume yet. If you sell project management software: "project management", "task tracking", "team collaboration tool".

2. Expand with tools

Use Google autocomplete, "People also ask", "related searches", and a keyword research tool to generate variations. Aim for 100–300 candidate keywords.

3. Cluster by topic

Group related keywords that would be served by the same page. "best project management software", "top project management tools", and "project management software comparison" all map to one comparison post.

4. Score and prioritize

For each cluster, weigh volume against difficulty against business value. A KD 25 keyword with 800 searches and high buyer intent is gold. A KD 80 keyword with 50,000 searches and pure browsing intent is a trap for a new site.

5. Map keywords to pages

One primary keyword per page. Secondary keywords in H2s. Never write two pages targeting the same primary — they'll cannibalize each other.

Long-tail keywords: the new-site cheat code

A long-tail keyword is a specific 3–6 word phrase with lower volume but lower competition. "best free seo audit tool for shopify" instead of "seo tool". Long-tail keywords:

Are easier to rank for.
Have higher conversion rates (specific = high intent).
Add up — 100 long-tails @ 30 searches each = 3,000 visits.

Common keyword research mistakes

Chasing volume over intent.
Ignoring difficulty as a new site.
Targeting the same keyword on multiple pages (cannibalization).
Writing for keywords with no commercial value.
Forgetting to refresh — re-do keyword research every 6–12 months as your site grows.

The best SEO strategy is targeting the easiest profitable keyword you haven't already ranked for — then doing it again next week.
