Keyword research is the process of figuring out what your potential customers actually type into Google when they’re looking for a business like yours — and it’s the foundation everything else in SEO gets built on. Skip this step, and even the best-written website content ends up optimized for words nobody is searching.

What Keyword Research Actually Means

At its core, keyword research answers one question: what words and phrases does your ideal customer use when they need what you offer? Not what you’d call your service internally — what a stressed-out homeowner or business owner actually types at 9pm when something breaks.

A plumber might think of their service as “residential plumbing repair.” Their customer types “toilet won’t stop running” or “emergency plumber near me.” Keyword research closes that gap.

Step 1: Start With What You Already Know

Before opening any tool, write down every service you offer in plain, everyday language — not the polished version from your website, the version a customer would actually say out loud to a friend.

Step 2: Use Google’s Own Autocomplete

Type a basic phrase like “how to fix a leaky faucet” into Google and look at what autocomplete suggests. Those suggestions are real, common searches. Scroll to the “People also ask” and “Related searches” sections at the bottom of results for more variations.

Step 3: Check Search Volume and Difficulty

A free tool like Google Keyword Planner, or a low-cost option like Keywords Everywhere, shows roughly how many people search a given phrase monthly and how competitive it is. For a local Iowa service business, a phrase with moderate volume and low competition is usually a better target than a high-volume phrase every national competitor is also chasing.

Step 4: Add Local Modifiers

“Emergency plumber” is competitive nationally. “Emergency plumber Urbandale” or “emergency plumber Des Moines” is dramatically less competitive and matches exactly how local customers actually search.

Step 5: Group Keywords by Intent, Not Just Topic

Someone searching “how does a water heater work” wants to learn something. Someone searching “water heater replacement cost Des Moines” is close to hiring someone. Build different content for each — educational content for the first group, a clear service page for the second.

Frequently Asked Questions

How many keywords should a small business target?

Most service businesses do well starting with 10-15 core keywords covering their main services plus local modifiers, rather than trying to rank for hundreds of terms at once.

Do I need paid tools for keyword research?

No. Google’s own autocomplete, the “People also ask” section, and Google Keyword Planner (free with a Google Ads account) are enough to get started. Paid tools add convenience, not a fundamentally different result.

How often should keyword research be revisited?

Every 6-12 months is generally sufficient for most small service businesses, unless you’re launching a new service line or noticing a significant shift in how customers describe what you do.
