How to Do Keyword Research for Free (Small Business Edition)

Keyword research sounds like something that requires a $99/month tool and a spreadsheet habit. For a small local business, it doesn't. Google gives away most of what you need — if you know where to look and, more importantly, what you're looking for.

This is the method we use in the research phase of client work, stripped to the free version.

First, understand what you're actually hunting

You're not looking for the biggest keywords. "Plumber" gets enormous search volume and will never send you a customer — it's too broad, too national, too competitive. You're hunting for three specific kinds of phrases:

1. Service + place: "drain cleaning Pembroke Pines" — someone near you, looking for the exact thing you sell.
2. Problem phrases: "water heater making popping noise" — someone with the problem you solve, one step before searching for the service.
3. Comparison and cost phrases: "tankless vs tank water heater cost" — someone deciding, ready to be influenced.

Small, specific keywords with buying intent beat big vague ones every time. Ten searches a month for "emergency drain cleaning near me" is worth more than ten thousand for "plumbing."

The free toolkit (all Google, all $0)

1. Google Autocomplete. Type your service slowly into the search box and read what Google suggests — those are real, common searches. Then add letters: "plumber a…", "plumber b…". Do the same with "why does my…", "how much does…", "best… near me" versions of your service.

2. People Also Ask. Search your main service and expand the "People also ask" box. Each question you expand spawns more. These are literal content ideas phrased exactly how customers phrase them — write pages and posts that answer them.

3. Related searches. Bottom of the results page. Often surfaces the comparison and cost phrases you wouldn't have guessed.

4. Google Keyword Planner. Free with a Google Ads account (you don't have to run ads). It gives search volume ranges by area — imprecise but plenty for prioritizing. This is the closest free thing to a "real" SEO tool.

5. Google Search Console — your secret weapon. If your site has been live a while, Search Console's Performance report shows the queries you already appear for. Look for queries where you're ranking on page two (positions 11–20): those are pages a focused improvement can push onto page one. This is the highest-ROI list in all of SEO, and it's sitting in a free dashboard most owners never open.

6. Your own inbox and call log. The words customers use in texts, calls, and emails are keywords. Marketing-speak ("premium hydration solutions") loses to customer-speak ("IV drip near me") every time.

How to judge whether a keyword is worth chasing

For each candidate phrase, ask three questions:

• Would the searcher pay me? "How to unclog a drain myself" attracts DIYers; "drain cleaning cost" attracts customers. Both can be worth content — but know which is which.
• Who currently ranks? Search it. If the whole first page is national giants and directories, pick a more specific variation. If you see other local businesses with mediocre pages — that's your opening.
• Does it deserve its own page? One page per distinct topic. "Water heater repair" and "water heater installation" are different searches with different intent — structure your site accordingly.

Turn the list into a plan

You'll end up with 20–40 phrases. Sort them into:

• Service pages — buying-intent keywords → one page each
• Blog posts — question and problem keywords → content that answers them
• City pages — service + neighboring-city phrases, if you genuinely serve them

Then work the list steadily — a page or post at a time, best opportunities first. That's the entire discipline.

The paid tools add competitor spying and prettier charts, and when a business outgrows the free method, we use them. But the free version above finds 80% of what matters for a local business — and it's the exact homework we'd assign before any SEO engagement anyway. Do it once and you'll know your market better than most of your competitors know theirs.
