Find searches that can become customers. Search volume matters less than customer intent and affordable economics.
Google Ads keyword research is the process of finding the searches a business may want to pay for.
The goal is not to collect the largest keyword list. It is to find searches that can become qualified calls, customers and revenue.
A keyword with 100 searches can be more valuable than one with 10,000 searches when those 100 people are ready to buy.
The Simple Answer
Start with the services or products the business wants to sell. Add the problems customers describe, signs of buying intent, urgency and location.
Then use Google Keyword Planner to estimate demand and cost.
Before adding a keyword, answer:
- What is the person likely trying to do?
- Do we sell the thing they want?
- Is the search likely to become a customer?
- What page should receive the click?
- Can the business afford the likely traffic cost?
Start With the Business, Not the Tool
Keyword tools generate ideas. They do not understand which customers the business wants.
Begin with a short business list:
- Highest-value services or products
- Most common customer problems
- Most profitable jobs
- Locations the business actually serves
- Urgent needs
- Products or services the business does not offer
For a garage-door company, the starting list might include:
- Garage door repair
- Broken spring repair
- Garage door opener repair
- Garage door installation
- Emergency garage door repair
Those services become the first keyword themes.
Build Keywords From Customer Language
Customers search in several ways.
| Search type | Example | What it may reveal |
|---|---|---|
| Service | garage door repair | Knows the service needed |
| Problem | garage door will not open | Describes the issue |
| Urgency | emergency garage door repair | Wants help quickly |
| Location | garage door repair Dallas | Wants a nearby provider |
| Comparison | best garage door company | Comparing options |
| Price | garage door spring repair cost | Researching affordability |
| Do-it-yourself | how to replace garage door spring | May not want a company |
Do not assume every search containing the service name is valuable.
“Garage door repair jobs,” “garage door repair manual” and “DIY garage door spring” describe the category without describing a customer.
Use Google Keyword Planner
Google Keyword Planner can:
- Suggest keywords from words or a website
- Estimate monthly searches
- Show competition and bid estimates
- Forecast clicks, impressions and conversions
- Organize ideas into ad groups
To find ideas:
- Open Keyword Planner from the Planning tools in Google Ads.
- Choose Discover new keywords.
- Enter a few services or a relevant website.
- Set the correct location and language.
- Review ideas by customer intent.
- Save useful terms to a plan.
Do not copy every suggestion into a campaign.
Keyword Planner may show related searches that are informational, irrelevant, outside the service area or too broad to support a useful ad.

Judge Intent Before Search Volume
Use three simple intent groups.
High Intent
The person appears ready to contact or buy.
Examples:
- garage door repair near me
- emergency garage door repair
- garage door company Dallas
- buy custom garage door
Middle Intent
The person may become a customer but needs more information.
Examples:
- garage door spring repair cost
- best garage door opener
- garage door replacement options
Low or Unclear Intent
The search may be educational, employment-related or do-it-yourself.
Examples:
- how garage doors work
- garage door repair jobs
- garage door repair training
- free garage door manual
Start with the searches most likely to produce customers. Expand after the account proves what works.
Group Keywords by One Customer Need
Do not place every keyword in one ad group.
Group keywords when the same ad and landing page can answer them.
Example:
| Ad group | Keyword theme | Landing page |
|---|---|---|
| General Repair | garage door repair, garage door company | Repair service page |
| Broken Springs | spring repair, broken garage spring | Spring repair page |
| Openers | opener repair, opener replacement | Opener service page |
| Installation | new doors, replacement doors | Installation page |
This makes the ad clearer and the reports easier to understand.
Darlington's campaign structure guide explains when to separate campaigns and ad groups.
Choose Match Types Deliberately
The three positive match types are broad, phrase and exact.
- Exact match provides the narrowest reach around closely related meaning.
- Phrase match allows more expansion while keeping more control.
- Broad match gives Google the widest reach and needs strong tracking and bidding.
Match type does not change whether a keyword idea is good. It changes how far Google may expand beyond it.
Start with Darlington's Google Ads match types guide before deciding how much reach to allow.
Build a Negative-Keyword List
Negative keywords block searches the business does not want.
Common negative themes include:
- Jobs and careers
- Training and certification
- Free
- Manual or PDF
- Wholesale
- Do-it-yourself
- Parts, when the business only sells service
- Locations outside the service area
Do not block a word simply because one search performed poorly. Make sure the negative does not also remove valuable customers.

Estimate the Economics
Keyword Planner forecasts are estimates, not promises. They are still useful for a first budget check.
Suppose a keyword group has:
- Estimated cost per click: $8
- Planned monthly spend: $3,200
- Expected website lead rate: 5%
- Expected lead-to-customer close rate: 25%
The estimated clicks are:
$3,200 ÷ $8 = 400 clicks
The estimated leads are:
400 clicks × 5% = 20 leads
The estimated customers are:
20 leads × 25% = 5 customers
The estimated ad cost per customer is:
$3,200 ÷ 5 = $640
The business can now compare $640 with the gross profit from one customer.
If the economics do not work, do not assume Google will create cheaper customers. Improve the offer, page, close rate or keyword focus—or choose a different opportunity.
Validate Keywords With Search Terms
Keyword research continues after launch.
Keywords are what the advertiser targets. Search terms are what people actually type.
Review the search terms report to find:
- Irrelevant searches to block
- Valuable searches to add
- New customer problems
- Location mistakes
- Differences between keyword themes
- Search terms producing qualified customers
The best keyword list comes from real customer and revenue data, not a planning tool alone.
Use Darlington's search terms report guide after the campaign begins spending.
Common Keyword-Research Mistakes
Choosing Only the Highest-Volume Keywords
High volume can include several different needs and weak intent.
Trusting Suggested Keywords Without Reading Them
The tool generates related language, not a finished business plan.
Ignoring Location
National search volume is not useful for a company serving one city.
Treating Bid Estimates as Guaranteed CPCs
Actual prices change by auction, competition, quality, location and timing.
Forgetting Negative Keywords
A good positive keyword can still match an irrelevant search.
Judging Keywords by Leads Instead of Customers
One keyword may produce many cheap forms and no sales. Another may produce fewer leads and more revenue.

What is the best tool for Google Ads keyword research?
Google Keyword Planner is the direct starting point because it provides keyword ideas, search estimates, cost estimates and forecasts inside Google Ads.
How many keywords should I start with?
Start with enough keywords to cover the highest-value customer needs without creating unrelated themes. A focused list is easier to fund and learn from than hundreds of weak ideas.
Should I choose keywords with the most searches?
No. Choose keywords with enough demand and strong customer intent. Search volume without buying intent can create wasted clicks.
What is the difference between a keyword and a search term?
A keyword is what the advertiser targets. A search term is what the customer actually typed before seeing or clicking the ad.
How often should I review keyword research?
Review search terms and customer quality regularly after launch. Add or remove keywords when real results reveal a better opportunity.
The Bottom Line
Google Ads keyword research is not about building the biggest spreadsheet.
Find the searches closest to a valuable customer. Group them around clear needs, estimate whether the traffic can work financially, and validate the plan using real search terms and sales.
