A psychiatric clinic we audited was running every keyword on phrase match. The account looked busy. Clicks were arriving, the daily budget was being spent in full, and the numbers on the surface looked like an account doing its job.
Then we looked at when the money went out. Most of it was spent before lunchtime, on searches that were adjacent to what the clinic offered but not what it offered. By early afternoon the budget was exhausted, so when somebody searched the exact treatment the clinic specialized in, the ad did not run.
They were not outbid. They were not out of position. They had simply already spent the day's money on other people's searches.
That is what match types decide, and it is why they are worth understanding properly.
Match Types Are What You Agree to Buy
A keyword is not a search. It is an instruction about which searches you are willing to pay for, and the match type sets how wide that instruction is.
The useful way to picture it is mesh size on a net.
Exact is the tightest mesh. You are buying that search and searches that mean the same thing.
Phrase is a medium mesh. You are buying searches that contain your keyword's meaning, with words around it.
Broad is the widest mesh. You are buying anything Google judges related, which can be very far from what you typed.
Nothing about this is a quality ranking. A wide net is not worse than a tight one. It catches more, and most of what it catches is not what you were fishing for.
The reason this matters more than it sounds is that the match type is set once and then governs every auction that keyword ever enters. You are not choosing a search. You are choosing a rule, and the rule runs thousands of times without anyone looking at it again.
All Three Have Drifted Looser
Here is the part that trips up anyone who learned this a few years ago and has not revisited it.
Exact match used to mean exact. If you set "therapist near me" as an exact match keyword, your ad showed for that search and nothing else. That is no longer true. Exact now includes close variants: reordered words, implied words, and queries Google judges to have the same meaning.
Phrase match absorbed the old broad match modifier and behaves considerably wider than the phrase match people remember.
Broad match has become genuinely broad, and with Smart Bidding attached it is a different product from what it was.
The practical consequence is that everything shifted one notch looser. Exact behaves roughly like the old phrase. Phrase behaves closer to the old broad. And broad reaches further than most advertisers expect.
If you built an account on the older behavior and have not touched the match types since, your net is a size wider than you think it is.
There is a reason for the drift, and it is not malice. Vast numbers of searches every day have never been seen before, so a system that only matched literal strings would miss real demand. Loosening the match types genuinely does surface searches worth having. It also surfaces a great many that are not, and the advertiser carries that cost, which is why the setting deserves a decision rather than a default.
How the Budget Actually Drains
The clinic's problem was not that phrase match is bad. It was arithmetic.
A daily budget is a rate, not a pot you can spend whenever you like. Google paces it across the day, but it can only pace what it is shown, and a loose match type produces far more eligible searches than a tight one. More eligible searches, at similar cost per click, means the budget meets its limit sooner.
The searches that arrive early are not sorted by value. They arrive in the order people search. So a loose account spends its budget on whatever comes first, and the high-intent search that would have converted arrives to find the campaign already limited.
Two symptoms to look for, both visible in the interface. Your campaign shows as limited by budget while its search terms report is full of things you would never have chosen. And your impression share lost to budget is high on the terms that matter most.
Broad Match Is Not the Beginner Setting
Broad match gets treated as the simple option because it requires the least thinking to set up. It is the opposite.
Broad match works when the algorithm has enough conversion data to tell a good query from a bad one, and when a bidding strategy is enforcing a cost ceiling. Under those conditions it finds searches you would never have thought to add, which is genuinely valuable.
Without them, it is an open tap. There is nothing constraining what it buys, and it will buy a very large amount of it.
This is why our sequence runs the other way round. New accounts launch on manual CPC and exact match, targeting the tightest possible set of terms, with the objective being page position on searches we already believe convert. Broad comes later, once there is conversion data and a target CPA acting as guardrails. That progression is chapter two.
The mistake is not using broad match. It is using broad match first.
Competitor Terms Are a Separate Campaign
Bidding on competitors' names is a legitimate tactic, and it belongs nowhere near your normal campaigns.
The economics are different in every direction. You cannot use their trademarked name in your ad copy, so your ad is less relevant to the query, which means a lower quality score and a higher cost per click. Conversion rates are usually lower, because the searcher was looking for somebody else. And it can provoke retaliation on your own name, which turns into two businesses paying more for traffic they both used to get cheaply.
None of that makes it wrong. It makes it a distinct bet with distinct math, and mixing it into a general campaign hides all of it inside an average.
There is one situation where it reliably pays: when a competitor is already bidding on you. At that point you are not opening a front, you are answering one, and the calculation is about what their traffic is worth rather than whether to engage at all.
Put competitor terms in their own campaign with their own budget, so you can see exactly what they cost and decide honestly whether they are worth it. Defending your own name is a different question, covered in chapter seven.
Where to Start and When to Loosen
Start tight. Exact match on the terms you already believe are your money searches. A small list you understand beats a large list you are guessing at.
Add phrase deliberately, one theme at a time, watching what it brings in.
Add broad last, and only with automated bidding and a target enforcing a ceiling.
Never mix match types loosely inside one ad group. If an exact and a broad version of the same term sit together, you lose the ability to bid them differently, which is most of the reason to separate them at all.
Give loose match types their own campaign when you can. A broad match campaign with its own budget cannot drain the budget of the exact match campaign that is actually producing your results.
That last point is the practical fix for the clinic's problem. Their tight terms and their loose terms were competing for the same daily budget, and the loose ones won every morning.
The Twenty Minute Version
- Open your keywords and read the match types. All phrase or all broad is the pattern to look for.
- Check whether the campaign is limited by budget. If it is, and the search terms report is full of things you did not intend to buy, you have found the drain.
- Look at your highest-value terms and confirm they are on exact match with a bid that reflects what they are worth.
- Check that competitor terms are not sitting inside a general campaign. If they are, move them out.
- Do not fix this by adding negatives alone. Negatives are the ongoing work and they get their own chapter later in this series. Match type is the upstream decision, and it is cheaper to buy the right traffic than to keep excluding the wrong traffic.
Match types are the least glamorous setting in Google Ads and one of the few that decides where every dollar goes before anything else gets a say.
We start every account tight and loosen it deliberately, because it is far easier to widen a net that is working than to work out which holes to close in one that is not. If you would rather we ran that sequence for you, we can. If you would rather do it yourself, go and look at what time of day your budget runs out. That single number tells you most of what you need to know.
