Free Keyword Research for a Local Business (and When a Paid Tool Is Worth It)

Keyword research sounds technical, but for a local service business it comes down to one question: what words do people type when they need what you do? Google’s SEO Starter Guide puts it simply: “Think about the words that a user might search for to find a piece of your content.” It also notes that people who know a topic well may search with different words than someone new to it. Your customers are mostly in the second group, and that’s where good keyword research starts.

Where do you find keywords for free?

Before any tool, write down the exact words customers use:

• How callers describe the problem (“water heater leaking,” not “tank failure”).
• Questions in your texts, emails and reviews.
• The words your crew uses when explaining a job to a customer.
• The names of the neighborhoods and towns you serve.

A chat AI tool can help you brainstorm variations from that list. It can’t tell you how many people search for them; for that, use the tools below. Our AI prompt starter kit has a brainstorming prompt.

What does Google Search Console show you?

Search Console is free, and Google says you don’t need it to appear in search results, but it “helps you understand and improve how Google sees your site.” Its Performance report shows clicks, impressions, click-through rate and average position, and the Queries dimension “groups your data by the search query users typed.” The default view covers the past three months.

That makes it the most direct free keyword tool there is: it shows real searches where your site already appeared. Look for:

• Queries with many impressions but few clicks. The page may need a clearer title or description; see our lead page guide.
• Questions you haven’t answered on your site yet.
• Service and town names you didn’t expect.

Google adds a caution: even if a query appears in your report, you might not see your site when you search it yourself, because results are specific to the time, place, device and recent history of the person searching.

How does Google Trends help?

Google Trends compares interest in phrases over time and by place. Google’s FAQ explains that Trends uses a sample of searches and normalizes it: each data point is divided by the total searches for that place and time, then scaled from 0 to 100. That means Trends shows relative interest, not the number of searches. It’s useful for questions like “do more people here say ‘lawn care’ or ‘yard service’?” and “when does interest in gutter cleaning rise each year?”

Is Google Keyword Planner free?

Keyword Planner is part of Google Ads. Google’s help page says it lets you discover keywords and view estimates of monthly searches and the cost to target them. It also says you must complete your Google Ads account setup by entering billing information to access basic features like “Get ideas for new keywords.” Entering billing information isn’t the same as running ads, but read the screens carefully so you don’t launch a campaign by accident.

Treat the numbers as estimates. For a small town, volumes for a specific service may be very low or not shown at all; that doesn’t mean nobody searches for it.

What about paid SEO tools?

Paid tools add competitor data and tracking. As one example, Semrush’s pricing page listed its SEO plan at $139 a month billed monthly, or $117.33 a month billed annually, when we checked on October 30, 2026, and a free plan with 10 reports per day. Prices change, so check the vendor’s page. Most small service businesses can learn a lot from the free tools first. We have no affiliate relationship with Semrush.

How do you turn keywords into pages?

1. Group the words by job. “Clogged drain,” “drain cleaning” and “slow sink” may all belong on one drain-cleaning page.
2. Give each real service its own page if customers search for it separately and you have something useful to say.
3. Use the main phrase naturally in the page title, the main heading and the opening paragraph.
4. Answer the questions you found as headings with short answers.
5. Don’t stuff. Google’s starter guide says keyword stuffing is against its spam policies, and that Google Search doesn’t use the keywords meta tag.
6. Be careful with city pages. Google’s spam policies list pages targeted at specific regions or cities that funnel users to one page as an example of doorway abuse. Our sister site’s service-area pages guide explains how to do these honestly.

Then wait and measure. Google’s starter guide says some changes take effect in a few hours and others can take several months. Check Search Console again after a few weeks, and count leads with GA4 key events.

Which keyword mistakes should you avoid?

• Chasing words your customers don’t use. Industry terms may look impressive but miss the people searching in plain words.
• Targeting areas you don’t serve. Visitors from outside your area won’t become jobs.
• Treating volume as the only signal. A phrase with a handful of local searches can matter more than a national term if each search is a ready-to-book customer.
• Writing for the tool instead of the reader. Google’s helpful-content guidance asks whether content is made primarily to help people; repeating a phrase over and over doesn’t help anyone.
• Expecting AI to know search numbers. A chat AI tool can suggest phrasings but doesn’t have Google’s search data unless it says where its numbers come from. Check every figure in a tool that shows its source.
• Changing everything at once. Change a few pages, note the date, and compare in Search Console a few weeks later.
