Keywords are the searches you agree to pay for, so choosing them is the most important decision inside the account. Good Google Ads keyword research is less about finding popular words and more about finding the words people type when they are ready to hire you. This chapter shows how to read search intent, how to get real numbers from Keyword Planner, how Miami neighborhoods and Spanish change the list, why competitor names are tricky, and how to group everything into tight ad groups by service.
Google defines keywords as words or phrases used to match your ads with the terms people search for. You choose them, and they decide which searches your ad can compete for. What beginners miss is that two searches with nearly the same words can come from completely different people.
Look at these four searches, all about air conditioning in Hialeah:
The first person has a broken AC and a phone in hand. The second is planning, maybe for weeks. The third wants to fix it alone. The fourth wants a job, not a technician. If our example HVAC company (an illustration, not a client) pays the same for all four clicks, three out of four are mostly money spent on the wrong people. That is why professionals start keyword research by asking "what does this person want right now?" before asking "how many people search this?"
High volume is tempting. "Air conditioning" alone gets far more searches than "ac repair hialeah." But a broad, vague keyword mixes all four intents together, and you pay for every one of them. A smaller keyword that only buyers type is usually worth more than a big one that everyone types.
Every search you might pay for falls roughly into one of these groups. Sorting your list this way is the single most useful exercise in this chapter:
| Intent | Typical words | Example (HVAC, dental, restaurant) | What to do |
|---|---|---|---|
| Ready to buy | repair, near me, emergency, open now, appointment, order, book, price, the service name plus a place | "ac repair hialeah", "emergency dentist doral", "cuban restaurant little havana" | Your core keywords. Most of the budget goes here. |
| Researching | cost, best, reviews, vs, how long, is it worth | "how much do dental implants cost", "best cuban sandwich miami" | Test carefully with a page that answers the question; often better served by SEO content. |
| Do it yourself | how to, diy, fix myself, reset, video, parts | "how to clean ac coils", "home remedy toothache" | Usually exclude. They want instructions, not a provider. |
| Job seekers and others | jobs, salary, hiring, training, course, school, license | "dental assistant jobs doral", "hvac school miami" | Exclude. They will never be customers. |
The "researching" row deserves a second look. Someone asking how much implants cost may become a patient worth thousands of dollars, but probably not today. For a dental office, that search can justify a helpful page on the site, and maybe a small test in ads, while the budget stays on "ready to buy" searches. Our guide on Google Ads vs SEO in Miami explains when that kind of research search is better served by organic content than by paid clicks.
The last two rows become your first list of negative keywords, words that stop your ad from showing. We build those lists properly in Chapter 4.
Guessing what people type is where most keyword lists go wrong. Google's free Keyword Planner, available inside a Google Ads account, gives you estimates instead of guesses. According to Google's Keyword Planner help page, it has two main uses: discovering new keywords related to your business or website, and getting search volume and forecasts for keywords you already have in mind.
A practical way to use it for a local business:
Two cautions from experience. First, the numbers are estimates, and Google itself says actual results depend on your bid, budget, ad quality, location targeting and customer behavior. Second, very specific local searches often show little or no data, and Google notes that keywords with very low volume are not shown at all. That does not mean nobody searches them. "Ac repair west hialeah" may show nothing, yet a few people a month may type it, and those few may be ready to buy.
What pros do: they treat Keyword Planner as a starting map and the real searches as the territory. After launch, the search terms report shows the actual searches that triggered your ads. Within a few weeks, that report teaches you more about your customers' words than any planning tool. Read it weekly, add the good searches as keywords and block the bad ones.
Miami is not one market. Someone in Kendall and someone in Brickell may never cross paths, and a technician in Hialeah may not want a call from Homestead. Keywords can carry that local meaning, but there is an important detail most owners do not know: the person searching rarely types their own neighborhood. Someone sitting in Doral usually types "dentist," not "dentist doral," and Google uses their location to show nearby results.
That is why the location settings of your campaign, which decide who can see your ads at all, do most of the local work. We set them carefully in Chapter 7. Local words in keywords still help in three situations:
One mistake to avoid: adding every city and neighborhood in South Florida to your keyword list "just in case." If you do not serve Homestead, a keyword with "homestead" in it just buys calls you will turn away. Keep local keywords to the places you actually want to work.
Miami's language mix is not a marketing cliché. Wikipedia's article on Miami describes it as the second-largest U.S. city with a Spanish-speaking majority, after El Paso, Texas, and the largest with a Cuban-American plurality. People here search in English, in Spanish, and very often in a mix of both, the blend Wikipedia's Spanglish article notes is an important part of Hispanic communities in places like Miami.
What that means for your keyword list:
The rule that overrides everything: only advertise in a language you can answer in. A Spanish keyword that leads to a voicemail in English, or a receptionist who cannot help, wastes the click and the customer's goodwill.
Sooner or later someone suggests bidding on a competitor's name, so your ad shows when people search for them. It is a common tactic, and it is worth understanding before you try it.
On the policy side, Google's trademark policy says it will not restrict trademarks used as keywords. What it can restrict, after the trademark owner files a complaint, is the use of the trademark in a direct competitor's ad text, and any use that is confusing or misleading. In other words, the keyword is generally allowed; putting their name in your ad is where trouble starts. For legal questions about a specific case, ask a lawyer, not an ad platform.
On the practical side, there are good reasons to be careful:
A more useful first step is protecting your own name. If competitors appear when people search for your business, a small campaign on your own brand is usually cheap, because your site is the most relevant result. Our guide on PPC costs in Miami discusses when that is worth it.
Inside a campaign, keywords live in ad groups. Each ad group holds a set of keywords, the ads that show for them, and the landing page they lead to. The rule professionals follow is simple: one ad group, one service, one promise. If the keywords in a group would need different ads to answer them well, they belong in different groups.
Here is how the example HVAC company in Hialeah might organize its first campaign:
| Ad group | Sample keywords | Ad promise | Landing page |
|---|---|---|---|
| AC repair | ac repair hialeah, ac not cooling, ac repair near me, emergency ac repair | Same-day repair, call now | AC repair page |
| AC installation | new ac installation, ac replacement hialeah, central ac install | Free in-home estimate | Installation page |
| Maintenance | ac maintenance plan, ac tune up hialeah, ac service | Yearly plan, priority visits | Maintenance page |
| AC repair (Spanish) | reparación de aire acondicionado, técnico de aire acondicionado hialeah, el ac no enfría | Servicio el mismo día | Spanish AC repair page |
Why bother with this structure? Because each ad can then speak directly to the search, which helps the ad relevance and expected click-through rate you met in Chapter 1, and the visitor lands on a page that matches. One large ad group with every keyword and one generic ad is the most common structure in neglected accounts, and the hardest to improve.
A few rules of thumb:
For the dental office in Doral, the same logic gives ad groups such as emergency visits, new patient cleanings, implants and Invisalign. For the Cuban restaurant, it might be dine-in, takeout and delivery, and catering, each with its own page.
How tightly each keyword matches the searches it triggers depends on match type, the subject of the next chapter. If you would rather have a team build and maintain this structure for you, that is part of our Google Ads management in Miami.
