Someone asks me "which match type should I use in Google Ads?" every second week. Half the time the person asking has already picked one, watched it not work, and switched. Then watched the new one not work either.
The question is wrong.
Google Ads match types aren't a preference. They're a fit test. Which one works for you depends on four things about your account, not on which one is theoretically "best". This post walks through the four things, the three recipes I actually use in client accounts, and what changed in 2026 that made this whole conversation move.
The 30-second refresher
Three match types, all still alive in 2026:
- Broad match (
keyword) - widest reach. Google shows your ad for anything it considers related, including queries that don't contain your keyword. - Phrase match (
"keyword") - middle ground. Google shows your ad on queries that include the meaning of your keyword. Meaning can be implied. - Exact match (
[keyword]) - tightest. Only queries with the same meaning or intent as your keyword. Close variants (plurals, reordering, function words, misspellings) still match.
Broad match modifier (+keyword +modifier) has been folded into phrase match since July 2021. If you see it in an old account, it behaves like phrase, not like the old BMM you remember.
If you want the full mechanics, syntax examples, and bulk conversion into all three formats at once, I built the Google Ads Match Type Tool for exactly that. It also has a bigger explainer if any of the above sounds unfamiliar. The rest of this post is about the strategy.
What changed in 2026
Two things worth knowing.
Google's official recommendation moved. Broad match plus Smart Bidding is now Google's default advice for most situations. From their own broad match guide: "It's critical to use Smart Bidding with broad match." That's not marketing spin, it's a policy statement. Broad match without Smart Bidding is officially off-piste. If you're still running manual CPC on broad keywords, you're using the campaign type in a way Google no longer really supports.
AI Max is eating campaign-level broad match. From 3 August 2026, you can't create new campaign-level broad match campaigns. From 1 to 30 September 2026, existing ones are automatically upgraded to AI Max. This one has caused a lot of confusion, so let me be clear: this only affects the campaign-level broad match setting (a checkbox at the campaign level), not individual broad match keywords in your ad groups. If you're using broad, phrase, or exact match on keywords the way most accounts do, nothing has changed for you. The AI Max upgrade only touches accounts that opted in to the campaign-level setting. I covered the broader AI Max context in Getting Your Google Ads Account AI Ready if you want the fuller picture.
There's also a quieter pricing shift. Between June 2023 and June 2025, average broad match CPCs rose 29%. Phrase match CPCs rose 43%. Phrase used to be the safer middle option; it's now often the more expensive middle option. That's per Search Engine Land's analysis of Google Ads auction pricing. Take that with the usual grain of salt, averages across the whole ad market don't mean it's true in your niche, but the direction matters.
A 4-question framework for choosing Google Ads match types
This is what I actually run through when I'm deciding a match type strategy for a new account.
1. Do you have Smart Bidding running on clean conversion data?
Smart Bidding needs roughly 30 conversions per campaign per 30 days to work well. If you're below that, broad match is guessing on thin data. Your CPCs go up, your ROAS goes down, you feel like broad "doesn't work" when actually it never had a chance. Under 30 conversions a month per campaign, phrase and exact are the safer default.
2. Is your negative keyword hygiene actually good?
Broad and phrase both need weekly search term reviews and a growing negative list. Exact match needs way less maintenance because the query surface is smaller. If you or your team aren't reviewing search terms weekly, exact match protects you from your own inattention. Broad match punishes it.
3. Are you running ecom or lead gen?
This is the one most people miss. Ecom sends Google a high volume of clean conversion signals (purchases with revenue attached). Broad match with Smart Bidding gets meaningfully better in that environment. Lead gen sends Google fewer, muddier signals (form fills that may or may not be qualified). Broad match in lead gen accounts has a much wider variance in outcomes. It can work brilliantly with Enhanced Conversions for Leads feeding qualified-lead data back to Google, or it can drown you in $60 clicks from job seekers. Ecom leans broader. Lead gen leans tighter unless the tracking is exceptional.
4. What's your tolerance for search term audit time?
Broad match is a weekly commitment. Phrase is fortnightly. Exact is monthly at most. If you're a business owner running your own ads without a dedicated 30 minutes a week, don't run broad. You'll accumulate wasted spend faster than you notice.
Three match type recipes I actually use
Recipe 1: High-intent lead gen, tight budget.
Exact and phrase only. Exact on your top 5-10 money keywords, phrase on the supporting theme. No broad. Ruthless negatives. Enhanced Conversions for Leads if the CRM allows. This is what I run for most local service businesses, most B2B, and any account under $3,000/month. It sacrifices reach for predictability, which is what those accounts actually need.
Recipe 2: Ecom with a Merchant Center feed and 100+ transactions a month.
Broad match on category and intent themes, exact on branded and top-performing product terms, target ROAS bidding. Weekly search term audits, aggressive shared negative lists. This is where broad genuinely earns its keep. You've got the data volume, the conversion values, and the automation Google needs. Fighting broad here usually means leaving money on the table.
Recipe 3: Established account looking to grow beyond the ceiling.
If your exact and phrase campaigns are already efficient and you've hit an impression share ceiling, a separate broad match test campaign with a small budget cap ($500 to $1,000 a month), tight audience signals, and daily search term reviews is the way to expand. Keep the test isolated. If it works, expand it. If it doesn't, kill it fast. Don't sprinkle broad keywords into existing ad groups and hope for the best.
Common false starts
"I'll just make everything broad and let the AI sort it out."
Google's rep will tell you this. Sometimes it works. More often, in accounts under a certain data volume, it burns through 20-40% of budget on queries that would never convert while Smart Bidding figures out your niche. Google's algorithm is optimising for its objective (spending your budget efficiently across their inventory), not yours (getting qualified leads). Those objectives overlap but they aren't the same thing.
"I'll duplicate every keyword in broad, phrase, and exact."
Common in older accounts. It creates internal auction competition, and Google picks whichever version it thinks will win the auction, which is usually broad (higher expected impressions). You've built a system where the tightest, most controlled version of each keyword rarely gets a chance. Either segment match types into separate ad groups with negative logic between them, or pick one match type per keyword and stick with it.
"Exact match is exact, so I don't need to check search terms."
Exact match includes close variants: plurals, misspellings, function words, reorderings, and same-meaning queries. Google's definition of "same meaning" has widened every year. Check your exact match search terms monthly at minimum. You'll find queries you didn't expect. The search term report guide walks through this properly.
My take
The match type argument gets treated like a religion. It isn't. It's a fit between what your account can support (data volume, tracking quality, audit time) and what each match type requires. Broad match zealots and phrase match hardliners are both wrong for most accounts, because most accounts sit in the middle where a mix is the right answer.
If I had to give a single default for the average account I audit: phrase match on the best commercial terms, exact match on the money keywords and brand, no broad match until Smart Bidding has enough clean data to justify it. It won't win every account, but it loses fewer than the alternatives.
Key Takeaways
- Google Ads match types aren't a preference, they're a fit test. The right mix depends on your account's data volume, tracking quality, negative keyword hygiene, and how much time you'll actually spend reviewing search terms.
- Broad match plus Smart Bidding is now Google's official recommendation, but it needs 30+ conversions per campaign per month and weekly search term reviews to work.
- The September 2026 AI Max migration only affects the campaign-level broad match setting, not individual broad match keywords. Most accounts aren't directly affected.
- Ecom accounts with clean conversion data lean broader. Lead gen accounts lean tighter unless the tracking is exceptional.
- Don't duplicate keywords across match types in the same ad group. Either segment or pick one per keyword.
- When you're ready to format a bulk keyword list into broad, phrase, and exact, the match type tool does the conversion in one paste.
If your match type mix has drifted, or you're not sure whether broad is genuinely earning its keep or just spending budget, that's the sort of thing worth a proper look. Get in touch and I'll tell you what I'd change.
