How to Do Keyword Research for Small Business: A Free Step-by-Step Guide

Picture a plumber in Austin who has decided his primary keyword is “plumbing services.” It’s a reasonable guess. He offers plumbing services. The problem is that “plumbing services” gets about 74,000 searches per month nationally, and page one is occupied by HomeAdvisor, Angi, Yelp, and the city’s largest multi-location companies, all with domain ratings above 70. His site, legitimately built and three years old, has a domain rating of 22. He is not going to rank for that term, not this year, and probably not ever without an enormous link-building effort. Meanwhile, “emergency plumber Austin” gets roughly 880 searches per month, page one has two independent local shops and a handful of listing sites, and the people typing it need someone right now. That is a winnable, high-value keyword.

Keyword research is the process of finding that gap: the space between what you assume your customers search for and what the data actually shows. Done well, it produces a list of specific, achievable terms that match what your pages do, attract people close to a buying decision, and can realistically be ranked without a six-figure SEO budget. This guide walks through a complete free method, from building your first list to deciding which terms to target first.

Before you start
The four qualities of a good target keyword

Not every keyword that’s related to your business is worth targeting. A useful keyword passes four tests. Here’s how to think about each one and how to check it quickly.

Step 1
Build your seed keyword list

A seed list is a rough collection of the terms your business naturally revolves around. You don’t need any tools for this step. What you need is 20 or 30 minutes to think systematically about three sources.

Your own service vocabulary

Write down every service you offer, every problem you solve, and every type of client you serve. A landscape company might list: lawn care, lawn maintenance, hedge trimming, garden bed installation, seasonal cleanup, spring cleanup, fall cleanup, residential landscaping, commercial landscaping. Each item is a potential seed keyword. Don’t edit the list yet; just get it all down.

Google autocomplete

Open Google in an incognito window and type your main service plus your city, but don’t press Enter. Just watch what the dropdown suggests. Every autocomplete suggestion is a real search term that real people have typed frequently enough for Google to surface. Type “landscaper Austin” and you might see “landscaper Austin TX cost,” “landscaper Austin near me,” “landscaper Austin reviews,” “best landscaper Austin.” Each of those is a seed keyword. Do this for every major service on your list.

People Also Ask

Now search your main service term and press Enter. Scroll down to the “People Also Ask” box. Every question there represents a search pattern. “How much does it cost to hire a landscaper?” and “What is the best time of year to hire a landscaper?” are both potential blog post topics and FAQ section entries. Screenshot the whole box. These questions tend to be long-tail and informational, which makes them easier to rank for and useful for building the kind of content that earns trust before a visitor reaches your service page.

Step 2
Expand with free tools

Once you have 20 to 40 seed keywords, three free tools can turn that list into 100 to 200 candidates with volume and difficulty data attached.

Google Keyword Planner

This is Google’s own tool for advertisers, but it works perfectly well for organic keyword research. Create a free Google Ads account (you don’t need to run any ads or add a payment method to use the tool). Navigate to Tools, then Keyword Planner, then “Discover new keywords.” Enter 5 to 10 of your seed terms at once and let the tool generate related variations. The volumes it reports are ranges rather than exact monthly numbers, but they’re accurate enough for triage. Any term showing “1K to 10K” monthly searches is worth investigating further. Any term in the “10 to 100” range might still be worth targeting if the intent is very specific and commercial.

Google Search Console

If your site has been live for at least three months, Google Search Console is your highest-value free tool because it shows terms you’re already ranking for. Go to Performance, then Queries. You’ll see every search term that has generated at least one impression for your site in the past three months, along with your average position for each. Any term where you’re already averaging position 6 to 15 is a priority target, because you are already visible and a well-optimized page or content update can move you from page two to page one with less effort than starting from scratch.

Ahrefs free keyword generator

The Ahrefs free keyword generator at ahrefs.com/keyword-generator requires no account. Enter any seed keyword, choose the correct country, and it returns up to 100 related terms with keyword difficulty scores. The difficulty scores are on a 0 to 100 scale; for a new or small site, target terms under 20. For a reasonably established site (a few years old, some backlinks), terms up to 35 are generally within range.

Small businesses rank fastest on long-tail keywords: phrases of three or more words with specific intent. A site with 40 pages each targeting a focused long-tail term can outperform a much larger site that spread its effort across broad, competitive terms. Lower competition, more specific searcher intent, and higher conversion rates all compound in your favor.

Step 3
Check the competition before committing

Volume and difficulty scores are estimates. The most reliable signal is what’s actually on page one right now. Before you commit to writing a 1,500-word page optimized for a keyword, spend five minutes on this manual check.

Open an incognito browser window (so your search history doesn’t skew the results) and search the keyword. Look at who is on page one. Ask yourself a simple question: are these large, national, general-authority publishers, or are they independent business websites?

If page one is Wikipedia, WebMD, Forbes, HubSpot, the CDC, or major news publications, that keyword belongs to a domain-authority game you can’t win with a local or niche site. Move on. If page one has independent business blogs, local company websites, and small publication sites, you have a real opening.

The quick test: copy 2 to 3 of the page-one URLs into the Ahrefs free site checker (ahrefs.com/website-authority-checker). Read their domain ratings. If the sites sitting on page one have domain ratings between 20 and 35, a well-structured, genuinely useful page on your site can compete. If they’re mostly above 60, the keyword is too competitive to be worth prioritizing unless your site has significant existing authority. For local SEO keywords, this check is especially forgiving because local pages often sit on sites with modest domain ratings.

Step 4
Map keywords to pages (and avoid cannibalization)

Keyword cannibalization happens when two pages on your site target the same primary keyword. Google sees both pages as candidates, gets uncertain which one to show, and often ranks neither as well as one consolidated, authoritative page would rank. The fix is simple: one primary keyword per page, decided before you write it.

The mapping logic is straightforward. Commercial intent keywords belong on the pages where people would actually buy or inquire. Informational keywords belong in your blog. Here’s the assignment pattern:

Build a simple spreadsheet with three columns: keyword, target URL, and page status (existing / needs update / needs to be created). This becomes your content roadmap. If you can’t assign a keyword to a specific URL without conflicting with another keyword already mapped to that URL, you have a cannibalization risk and need to either consolidate pages or split them clearly by intent.

Step 5
Prioritize your list

After working through steps one through four, you’ll have 30 to 60 mapped keyword opportunities. You can’t act on all of them at once, and trying to will dilute your effort. Here’s how to sequence them.

Start with commercial intent. A person searching “hire web designer Austin” is much closer to a transaction than a person searching “what does a web designer do.” Your service pages and location pages have the most direct revenue connection, so they get optimized first. If they’re already live but thin, update them before creating new content.

Then prioritize your quick wins. Export your Search Console queries and filter for terms where you’re currently averaging position 6 to 15. These are pages that already have some traction. Adding 200 words of more specific content, tightening the title tag, and improving the internal linking structure can push them from position 11 to position 4 faster than any new page could rank from scratch.

Then build the informational content that supports your commercial pages. A blog post explaining what to look for when hiring a web designer, if it links internally to your web design service page, passes topical authority to that page and gives you a second entry point for people who are researching rather than ready to buy. A well-built content marketing strategy for a small business is largely this: informational posts that funnel readers toward commercial pages, with internal links that make the relationship explicit.

Common questions
Frequently asked questions

Keyword research is not a one-time event. The first time through, the goal is to stop guessing and start with a concrete list of terms you have a real reason to believe you can rank for. Every revision after that is about refining the map as your site gains authority and your understanding of your customers’ language gets sharper.

How AI tools are changing keyword research in 2026

ChatGPT, Claude, and Perplexity have become useful first-pass tools for keyword brainstorming. Ask an AI: “What questions would a small business owner in your city ask when looking for a web designer?” and you get a list of angle variations faster than manual Google autocomplete scrolling. The AI draws from training data about how people phrase questions, which can surface semantic variations you would not think to type.

But AI tools have a hard limit: they cannot give you search volume or keyword difficulty data. They are brainstorming tools, not keyword research tools. A keyword list from ChatGPT with no volume validation will include terms nobody actually searches for alongside genuinely valuable targets. Always run AI-generated keyword ideas through Google Keyword Planner or another volume source before building content around them.

The more interesting shift is that keyword research now has to account for AI search behavior alongside traditional Google search. A query like “best web designer for small business” might trigger a Google AI Overview that answers the question without a click. Informational queries with clear factual answers are the ones most likely to become zero-click via AI Overviews. Keyword strategy in 2026 needs to separate two categories: transactional and local keywords where traditional ranking still drives clicks, and informational keywords where appearing in the AI Overview itself is the goal, even without a direct click.

For informational keywords, the question becomes not just “can I rank for this?” but “can I be cited by Google AI, ChatGPT, or Perplexity when someone asks this?” The content format requirements are slightly different: AI citation favors direct, confident answers to specific questions, specific statistics with attribution, and structured comparisons. These are the same formats that win featured snippets in traditional search, so optimizing for AI citation and traditional ranking are largely aligned.
