How to Do Keyword Research Step by Step (With Free Tools)

Keyword research is not about finding the biggest number in a tool. It is about learning the exact words your customers type when they need what you sell, then giving each of those needs a page that answers it better than anyone else. Done well, it tells you which pages to build, what to call them and what to put on them. This tutorial walks through keyword research step by step using free tools.

What you are looking for

For every keyword, you are judging four things:

A keyword with 50 monthly searches and strong buying intent is often worth more than one with 5,000 searches from people who will never buy.

Step 1: Start with customers, not tools

Before opening any tool, write down how customers describe their problems. Sources:

• Questions customers ask on calls, emails and in person
• Words used in reviews, yours and competitors'
• Notes from sales conversations
• Service names you use internally, and how customers actually say them

A plumber might call it "water heater replacement," while customers search "no hot water" or "water heater leaking." Both matter, and they want different pages.

Tip: Make a spreadsheet with three columns: the problem, the words customers use, and the service or product that solves it. This becomes your seed list.

Step 2: Expand with free tools

Using autocomplete

Type your seed keyword into Google slowly, then add letters (a, b, c) or question words (how, why, cost, best, near). Write down every suggestion that matches a real customer need.

Using People also ask

Search your seed keyword, open the People also ask questions, and note them. Each expanded question reveals more. These are perfect for FAQ sections and supporting articles.

Using Search Console

If your site already exists, Search Console shows the queries you appear for, including ones you never targeted. These are your easiest wins.

Step 3: Group keywords by intent

Group similar phrases that want the same answer. For example:

The rule: one page per intent, not one page per keyword.

Step 4: Read the results page

Tools estimate. The results page tells the truth. For each priority keyword, search it in a private browser window and look at:

• What type of pages rank: service pages, blog posts, product pages, directories, videos?
• Who ranks: big national brands, local businesses, forums?
• What features appear: a local map pack, People also ask, shopping results, an AI Overview?
• How good the content is: could you write something more helpful, more specific or more trustworthy?

If the top results are thin pages from small sites, you have a real chance. If every result is a national brand with deep content, choose a more specific long-tail phrase.

Step 5: Prioritize long-tail keywords

New sites usually win first with long-tail keywords:

Long-tail phrases have lower volume but much clearer intent and less competition. Ten long-tail pages that each bring a few qualified visitors can outperform one broad page that never ranks.

Step 6: Build your keyword map

A keyword map assigns every keyword group to exactly one page. Use a simple worksheet:

This prevents two pages from competing for the same search and shows you exactly which pages to create next.

A worked example: a local bakery

A bakery wants more custom cake orders.

1. Seed list from customers: "birthday cake," "custom cake," "wedding cake tasting," "gluten-free cake."
2. Autocomplete adds: "custom birthday cakes near me," "how far in advance to order a wedding cake," "gluten free bakery [city]."
3. Keyword Planner shows "custom cakes [city]" with modest volume, "gluten free bakery [city]" lower volume but strong intent.
4. Results page check: "custom cakes [city]" shows a map pack and a few local bakery pages with thin content. Opportunity.
5. Keyword map:
6. /custom-cakes: "custom cakes [city]"
7. /wedding-cakes: "wedding cakes [city]" plus tasting questions
8. /gluten-free-cakes: "gluten free bakery [city]"
9. /blog/how-far-in-advance-to-order-a-wedding-cake: informational support article linking to /wedding-cakes

Five focused pages, each matched to a real search, with internal links between them.

Step 7: Revisit every quarter

Keyword research is not one-and-done. Every three months:

• Check Search Console for new queries you appear for
• Look for queries ranking in positions 8 to 20, which are close to page one
• Add new questions customers are asking
• Update your keyword map

Keyword research checklist

• ☐ Seed list built from customer language
• ☐ Autocomplete and People also ask explored
• ☐ Volume ranges checked in Keyword Planner or Bing
• ☐ Keywords grouped by intent
• ☐ Results page reviewed for top priorities
• ☐ Long-tail opportunities chosen
• ☐ Keyword map completed: one intent per page
• ☐ Quarterly review scheduled

Mistakes to avoid

• Chasing high-volume keywords with no buying intent
• Trusting tool volume estimates as exact numbers
• Creating separate pages for tiny keyword variations
• Skipping the results page check
• Writing content before mapping keywords to pages
