Match type controls how much freedom Google has to interpret your keyword before showing your ad. Three settings, and every one is broader in practice than its name suggests. Even exact match now covers plurals, misspellings and rewordings that Google judges to mean the same thing.
Briefly explained
- Three settings: broad, phrase, exact, from loosest to tightest.
- All three have loosened over the years.
- Looseness is where an ad budget leaks.
- Only the search terms report shows which searches your keyword actually caught.
What does each one actually trigger?
- Broad match: Anything Google considers related, including searches that share no words with your keyword at all.
- Phrase match: Searches that include the meaning of your phrase, in order.
- Exact match: Searches with the same meaning as your keyword, including close variants.
The gap between what these sound like and what they do is the single most expensive misunderstanding in a new account.
Why does it cost so much to get wrong?
Because clicks are priced by what a customer is worth, not by how likely this particular visitor is to become one. A loose match on a valuable keyword pulls in parts buyers, students, job seekers and neighboring regions, all at the price of a buyer.
Tight matching does not fix a weak offer. It does stop you from paying premium rates for an audience that was never going to call.
How should you run it?
- Start with phrase and exact on the services and areas you know convert
- Read the search terms report weekly, and add negatives from what really matched
- Keep one theme per ad group, so the ad can answer every keyword in it
- If you test broad match, give it its own campaign and its own budget, so it cannot quietly consume the keywords that already work
When is broad match worth it?
When three things are true at once: conversion tracking is reliable, there is enough conversion history for the bidding to learn from, and the negative list is already doing its job. Broad match with automated bidding can find searches you would never have written down. Missing any of the three, it is simply a bigger leak.
What do the terms mean?
- Close variant: A search Google treats as meaning the same as your keyword.
- Search terms report: What people actually typed. Not the same as your keyword list.
- Negative keyword: An exclusion that stops a match from happening.
- Keyword cannibalization: Two of your own pages competing for one search. See keyword cannibalization for the organic version of the same problem.
