Tips for Choosing the Best Google Ads Keywords: Buy Intent, Not Traffic
Most wasted ad spend traces back to keywords that attract researchers, job seekers and bargain hunters instead of buyers. Choosing well means ranking every candidate term by how close the searcher is to hiring you, then fencing the campaign off from everything else.
The best Google Ads keywords, still called AdWords keywords by many advertisers, are the searches people type when they are ready to buy what you sell, in the area you serve. Start from buyer intent, choose match types that keep control, add negative keywords before launch, and let the search terms report tell you what to cut each week.

How do you judge which keywords are worth paying for?
Ask what the searcher wants to happen next. 'Emergency water heater repair near me' wants a technician today; 'how long does a water heater last' wants an article. Both are relevant to a plumber, but only the first is worth paying for. Sort every candidate into the intent tiers in the table and start with the top two.
Volume is a poor first filter. A term searched a few dozen times a month by people ready to book often outperforms a popular term searched mostly by researchers. Small businesses especially should prefer specific, modest terms they can afford to win over broad ones that drain the budget by lunchtime. Research-stage searches are still worth reaching, but usually more cheaply through SEO-focused content writing than through paid clicks.
| Intent tier | Example search | What the searcher wants | Bid on it? |
|---|---|---|---|
| Urgent buyer | emergency plumber near me | Someone at the door today | Yes, first priority |
| Comparing providers | water heater installation cost [city] | Prices and a shortlist to call | Yes, with a clear price or quote offer |
| Researching a problem | why is my water heater making noise | An explanation | Rarely; better served by a blog post and SEO |
| Do it yourself | how to replace a water heater element | Instructions, not a plumber | No; add 'how to' and 'DIY' as negatives |
| Not a customer | plumber jobs, plumbing apprenticeship | Employment | No; add 'jobs' and 'apprenticeship' as negatives |
Which keyword match type should you use?
Google offers three. Broad match, the default, can show ads on searches related to your keyword; phrase match on searches that include its meaning; exact match on searches with the same meaning or intent. Google's match types help page gives the syntax: quotes for phrase, square brackets for exact.
For a new account with a small budget, phrase and exact match keep spend on relevant searches while you learn. Broad match can work once conversion tracking is reliable and smart bidding has data to steer by; without that data it tends to wander into loosely related searches you would never have chosen.
How do negative keywords protect your budget?
Negative keywords stop ads from showing on searches that contain words you exclude, such as 'free', 'jobs', 'salary', 'DIY' or a competitor's brand. Build a starter list before launch from the obvious mismatches, then grow it weekly from real searches. A well-kept negative list is usually the fastest way to cut waste in an existing account.
One detail catches people out. Google's negative keyword guidance says negatives do not match close variants: excluding 'job' will not block 'jobs'. Add the plural, common misspellings and obvious variations yourself.
How many keywords should an ad group or campaign have?
Few enough that one ad can speak directly to every keyword in the group. In practice that means a tight theme per ad group, such as 'water heater repair' separate from 'water heater installation', each with a handful of closely related terms and a landing page about exactly that service. Campaigns split by service or location, not by match type.
Keyword Planner, free inside a Google Ads account once billing details are entered, suggests related terms and estimates monthly searches and costs, according to Google's Keyword Planner help. Treat its suggestions as a starting list to filter by intent, not as a list to upload whole.
How do you keep improving keyword choices after launch?
Read the search terms report every week. It shows the real searches that triggered your ads, which are often surprisingly different from the keywords you chose. Promote converting searches to keywords of their own, add irrelevant ones as negatives, and pause keywords that spend without producing calls or forms after a fair trial.
Ad copy should mirror the keyword and stay accurate. The Federal Trade Commission's advertising FAQs require evidence for claims before an ad runs, so a headline promising 'same-day service' needs to be true for every searcher who clicks.
When is it better to hand keyword management over?
When the weekly review keeps slipping, or when spend rises without a matching rise in leads. Lightray's Google Ads management covers tracking, keywords, negatives and reporting from an account you own. If you are still deciding whether paid search suits you, read our take on whether PPC is worth it; if you want to see where paid ads sit beside organic rankings, Lightray's search engine marketing service plans the two together. All of Lightray's work is remote.

Frequently asked questions
How much budget do I need to test a set of keywords?
Enough for your top-tier keywords to collect a meaningful number of clicks in a month, which depends on your local cost per click. Keyword Planner's cost estimates give a starting point. Google bills spend directly; Lightray quotes any management fee separately after a free review.
How long before I know whether my keywords are right?
The search terms report shows obvious mismatches within the first week. Judging whether a keyword produces customers takes longer, usually a month of conversion data, and longer still for services with a long decision time.
Can Lightray review our Google Ads keywords remotely?
Yes. All work is remote. You grant access to your Google Ads account, Edward reviews the keywords, negatives and search terms, and walks you through the findings on a video call. The account stays in your name.
What do you need from us for a keyword review?
Access to the Google Ads account, a list of the services you most want to sell, the areas you serve, and any services or customer types you do not want. If conversion tracking exists, access to Google Analytics helps too.
