Broad match vs. exact match in 2026: why Google says forget exact match

Not long ago, exact match was the gold standard of Google Ads. Exact keywords, exact matches, exact control. Every PPC specialist told you: “Start with exact match so you don’t waste money on junk." And they were right — in 2020.

In 2026 Google says the opposite. The official recommendation reads: broad match combined with Smart Bidding is the new default. And data from campaigns that made the switch to broad match shows why — AI Max for Search delivers on average 14% more conversions for campaigns that previously ran on exact and phrase match.

What changed? And does it mean you should switch all your keywords to broad match? Not so fast. The reality is — as always — more complicated. In this article we’ll explain the real difference between the match types in 2026, when broad match makes sense, and when it can cost you money.

The short version for those who don’t have time to read the whole article

• Broad match in 2026 isn’t the “broad match" of 2019. Google has substantially improved it — combined with Smart Bidding, it takes into account user intent, context, and conversion history. It’s not “show the ad on anything."
• Google officially recommends broad match + Smart Bidding as the default combination. The system needs room to learn, and broad match gives it that room. Exact match constrains the algorithm.
• But broad match only works with enough data. The minimum is 30+ conversions a month and active Smart Bidding. Without that, broad match really does spend on junk.
• Exact match still has its place: brand campaigns, regulated industries, very small budgets, and campaigns where you need absolute control over queries.
• The best approach in 2026: hybrid. Broad match for volume campaigns with Smart Bidding, exact match for brand and specific high-value queries. Not one or the other — both.

What changed: match types in 2026

Before we get into the comparison, let’s clarify what each match type actually does in 2026. Because it has changed quite a bit over the last few years.

Exact match

It used to mean: the ad shows ONLY on this exact query. Today? Google has expanded exact match to include “close variants" — synonyms, typos, and rewordings with the same intent. So [red running shoes] can also show on “running shoes red" or “red shoes for running."

It’s still the most precise match type, but it hasn’t been “exact" in the original sense for a long time.

Phrase match

The ad shows on queries that contain your phrase or a close variant of it, with additional words before or after. “running shoes" will show on “best running shoes 2026" or “cheap running shoes for women."

Broad match

And here’s the big change. Broad match in 2026 isn’t the broad match of 2019, when an ad for “running shoes" would show on “how to replace a brake shoe on a car." Today’s broad match takes into account:

• User intent — not just the words, but what the person probably wants
• Context — previous searches, location, device
• Conversion history in the account — which queries led to conversions in the past
• Smart Bidding signals — the algorithm not only expands queries but also adjusts bids according to the likelihood of conversion

That’s the key difference. Broad match without Smart Bidding is still dangerous — it spends on everything. Broad match with Smart Bidding is smart — it expands reach, but the algorithm bids low on irrelevant queries and high on relevant ones.

Why Google is pushing broad match

Google has a pragmatic reason: its AI works better with more data. Exact match limits which queries the ad shows on — and thereby limits the data Smart Bidding learns from. Broad match gives the algorithm room to explore queries you’d never add manually but which bring in conversions.

From Google’s point of view the logic is clear:

1. Broad match = more impressions = more data

2. More data = better Smart Bidding = better conversions

3. Better conversions = a happy advertiser = more money into advertising

Cynically put: Google earns more on broad match because it shows ads on more queries. But the data shows that with the right setup the advertiser profits too — because the algorithm finds conversions where you wouldn’t look for them manually.

When broad match works (and when it doesn’t)

Broad match works if:

• You have active Smart Bidding (Target CPA, Target ROAS, Maximize Conversions/Value). Without Smart Bidding, broad match has no brakes.
• You have 30+ conversions a month. The algorithm needs data to learn which queries convert.
• You have proper conversion tracking (Enhanced Conversions, Google Ads tag). The algorithm is only as good as the data it receives.
• You review search terms regularly and add negative keywords. Broad match degrades without maintenance.

Broad match doesn’t work, or is risky, if:

• You don’t have Smart Bidding. Broad match with manual bidding = uncontrolled spending.
• You have a low conversion volume (under 15 a month). The algorithm has nothing to learn from.
• You have a small budget (under 15,000 CZK/month, ≈ €600). Broad match burns the budget testing queries that don’t convert.
• You’re in a regulated industry (healthcare, law, finance). Broad match may show your ad on queries you’re not allowed to advertise on.
• You don’t review search terms. Without regular cleaning, broad match gradually drifts into irrelevance.

The hybrid approach: the best of both worlds

In practice we recommend a combination:

In practical terms: run a brand campaign on exact match and one or two non-brand campaigns on broad match with Smart Bidding. Review search terms regularly (ideally weekly) and add negative keywords.

How to move from exact to broad match safely

If you’ve been running on exact match so far and want to try broad:

Step 1: Don’t switch your existing keywords. Add new broad match keywords to an existing campaign, or create a new campaign for the test.

Step 2: Make sure you have Smart Bidding (Target CPA or Target ROAS). Don’t turn on broad match without it.

Step 3: Set negative keywords preventively — exclude the obvious irrelevancies in advance (jobs, employment, how to make, free, secondhand...).

Step 4: Watch the search terms report every week. The first 2–3 weeks will be wild — the algorithm is testing. Add negative keywords as you go.

Step 5: Evaluate after 4 weeks. Compare the CPA/ROAS of broad match vs. exact match. If broad match achieves similar or better results with higher volume — scale it.

At LK Media we moved our clients to a hybrid approach over the course of 2025. The result: broader reach, more conversions, similar efficiency. The key was patience (the first 2 weeks look terrifying) and consistent cleaning of search terms.

Conclusion

Broad match vs. exact match isn’t an “either/or" question. In 2026 the right answer is “both" — broad match for volume and discovering new queries, exact match for control and precision. What matters is having the right conditions: Smart Bidding, enough conversions, quality tracking, and regular maintenance of negative keywords.

And if you’re still running exclusively on exact match “because that’s how it’s done" — consider a test. You may be losing conversions you don’t even know about.

Frequently asked questions about Google Ads

Is broad match safe in 2026?

Combined with Smart Bidding and regular review of your search terms, yes. Broad match without Smart Bidding is risky — it has no brakes. Smart Bidding ensures the algorithm bids low on irrelevant queries and high on relevant ones. But even so, you need to check search terms weekly and add negative keywords.

Can I switch all my keywords to broad match at once?

We don’t recommend it. Start with a test — add broad match keywords to one campaign or create a new one. Compare performance after 4 weeks. If the results make sense, expand. A wholesale switch can cause a short-term drop in performance during the learning phase.

Why is Google pushing broad match — isn’t it just for their own profit?

Partly yes — broad match means more impressions and more revenue for Google. But the data shows that with the right setup the advertiser profits too. Smart Bidding + broad match can find conversions on queries you’d never add manually. The key is the right conditions: 30+ conversions, Smart Bidding, quality tracking.

When is exact match still better?

For brand campaigns (full control over brand queries), regulated industries (healthcare, law), very specific high-value products, and situations with a small budget or a low number of conversions. Exact match makes sense wherever you need absolute control.

What’s the difference between broad match and AI Max for Search?

Broad match expands your keywords to related queries. AI Max for Search goes further — it can show your ad even on queries with no link whatsoever to your keywords, if it predicts a conversion. AI Max also dynamically generates ad copy and redirects to the most relevant pages of your website. Broad match is “expansion," AI Max is “full automation."
