Keyword research: a practical guide for beginners

What keyword research actually is

Keyword research is the process of finding the words and phrases your audience types into search engines, then deciding which of those phrases are realistic for your site to rank for. Done well, it tells you what to write next; done poorly, you spend months on pages nobody searches for.

Step 1 — Seed keywords

Start with 5 to 10 broad terms that describe what you do. If you sell running shoes, seeds are "running shoes", "trail running", "marathon training", and so on. These are not your targets — they're the starting point for discovery.

Step 2 — Expand with free sources

Google autocomplete: type your seed and note every suggestion.
People also ask and Related searches at the bottom of a Google SERP.
Reddit and forums: search "site:reddit.com " to see the exact phrasing real users use.
Your own site search and support tickets: gold for commercial intent.

Aim for a raw list of 100–300 phrases before filtering.

Step 3 — Group by intent

Every query maps to one of four intents:

Informational — "how does X work". Blog posts, guides.
Navigational — "brand X pricing". Landing pages.
Commercial — "best X for Y". Comparison content.
Transactional — "buy X". Product pages.

Group your list by intent before evaluating volume. A high-volume informational keyword doesn't help a checkout page.

Step 4 — Evaluate difficulty

Two quick signals you can read for free:

SERP composition: open the top 10 results. Big brands and Wikipedia everywhere means high difficulty. A mix of small blogs means you have a chance.
Content depth: if the top result is a 3,000-word guide with original data, you'll need to match it.

Step 5 — Prioritize

Pick keywords where all three are true:

The intent matches a page you can genuinely serve.
The top results aren't dominated by giant brands.
The topic is close enough to your existing content that internal links make sense.

Common mistakes

Chasing volume alone — 10,000 searches a month is useless if you can't compete.
One keyword per page — modern pages rank for dozens of variations. Cover the topic, not the phrase.
Ignoring long-tail — "best waterproof trail running shoes for wide feet" converts better than "running shoes".

Tools that help

Keyword Density Checker — audit an existing page.
Meta Tag Generator — turn a target keyword into a strong title and description.
SERP Snippet Preview — see how your title and description will look in Google.

What to do next

Pick three keywords from your prioritized list. For each, outline a page that fully answers the query — better than the current top result. That's your next month of content, sorted.
