Which Keyword Match Type Should I Use for New Google Ads Campaigns? (UK Guide 2026)

The short answer

For most new Google Ads campaigns in 2026, start with phrase match. It strikes the best balance between reach and intent control - especially while the campaign is still gathering conversion data. Layer in exact match for your highest-converting head terms, and only move to broad match once you have at least 30 conversions per ad group, a tight negative keyword list, and a fully-trained Smart Bidding strategy (Target CPA or Target ROAS).

That's the universal default. The right answer changes based on budget, vertical, conversion volume, and how mature your tracking is. Ben has launched hundreds of new campaigns across the 250+ UK accounts he's reviewed, and the launch sequence below is what works most consistently.

The three match types in 2026

After Google retired Broad Match Modifier (BMM) in 2021 and folded its behaviour into phrase match, only three match types remain:

• Exact match - tightest. Triggers on searches with the same meaning as the keyword.
• Phrase match - middle ground. Triggers on searches that include the meaning of the keyword.
• Broad match - widest. Triggers on any search Google deems related, including synonyms and intent variations.

How each match type actually works in 2026

Exact match - [keyword]

Triggers on searches with the same meaning as your keyword - not just the exact words. So [plumber london] will also serve for "london plumber", "plumbers in london", and "best plumber near london". It will not serve for "emergency plumber london" (different intent layer added).

Best for: proven head terms, brand keywords, competitor names, defensive plays.

Phrase match - "keyword"

Triggers on searches that include the meaning of your keyword. "plumber london" will serve for "emergency plumber london", "cheap plumber london", "24 hour plumber london" - but not for "boiler engineer london" (meaning shifted).

Best for: launching new campaigns, scaling existing winners, capturing long-tail without losing intent control.

Broad match - keyword

Triggers on anything Google's AI considers related: synonyms, related concepts, recent search behaviour, location, profile data. Broad match for "plumber london" can serve for "drain unblocking", "leaking tap repair", "find a tradesman near me" - the further from the literal keyword, the more reliant you are on Smart Bidding to filter quality.

Best for: mature accounts on Target CPA / Target ROAS with strong conversion data and ruthless negative keyword discipline.

Which match type should you use for new campaigns?

The default for 95% of new campaigns: phrase + exact. Add broad only when you've earned the right to.

How Smart Bidding changed the match type rules

The old playbook was simple: exact match was safe, broad match was a budget incinerator. That changed when Smart Bidding (Target CPA, Target ROAS, Maximise Conversions) became the default for most accounts.

Smart Bidding uses real-time auction signals - device, location, time, audience, query intent - to decide whether to enter an auction and what to bid. Paired with broad match, the AI can technically explore more queries while still filtering for conversion likelihood. Google's own internal data claims advertisers see 25%+ more conversions when broad match is paired with Smart Bidding.

That number is real - but only when the conditions are met:

• You have at least 30 conversions per ad group over the past 30 days.
• Conversion tracking is bulletproof (no double-counting, proper offline import where relevant).
• You have a tight negative keyword list of at least 50-200 terms.
• Your bid strategy has been running long enough to learn (typically 2-4 weeks).

Without those four conditions, broad match in a new campaign behaves exactly like it always did - a budget incinerator that surfaces low-intent traffic with no way for the bidding to know better.

Ben's launch sequence for new campaigns

This is the exact sequence used in Phase 2 of the 90-Day Revenue Takeover when launching new campaigns in a fresh account or fresh vertical.

Week 1-2: Phrase match foundation

Launch with phrase match across 10-30 carefully chosen keywords per ad group. Use Maximise Clicks or Manual CPC bidding to get clean cost data. Build a starter negative keyword list of 30-50 obvious exclusions (free, jobs, DIY, cheap if not relevant, etc.).

Week 3-4: Add exact match for winners

Pull the Search Terms report. Identify queries that converted at or below target CPA. Add those as exact match keywords in their own ad groups. Increase negative keyword list to 100+ terms based on the search terms data.

Week 5-8: Switch to Smart Bidding

Once you have 30+ conversions in the campaign, switch from Manual / Max Clicks to Maximise Conversions or Target CPA. Let it train for 14 days untouched.

Week 9-12: Test broad match cautiously

Only after the bid strategy is trained: clone a winning ad group, change keywords to broad, set the daily budget to no more than 20% of the campaign's budget. Compare CPA for two weeks. Keep, expand or pause based on data.

This sequence has been more reliable across 250+ accounts than any "broad match from day one with Smart Bidding" launch.

Match type by budget level

Under £2,000/mo

Phrase + exact only. There isn't enough volume for Smart Bidding to learn from broad match - you'll burn the budget on exploratory queries before getting useful data.

£2,000-£10,000/mo

Phrase + exact for 80% of the keywords, with a small (10-20% budget) broad match test ad group once Smart Bidding is trained. This is the sweet spot for most UK SMBs.

£10,000-£50,000/mo

50/50 phrase and broad split, with exact match reserved for top head terms and brand. Negative keyword maintenance becomes a weekly task at this spend level.

£50,000+/mo

Broad match dominant on Target ROAS, with daily search terms reviews and aggressive negative keyword automation. At this volume, broad match consistently outperforms phrase - but only with the operational discipline to match.

Why negative keywords matter more than match type

Match type controls the front door. Negative keywords control everything else. Ben has seen broad match campaigns outperform exact match campaigns purely because the broad match account had a 500+ negative keyword list and the exact match account had 5.

Minimum negative keyword commitments by match type:

• Exact match: 20-50 negatives (low spillover, low maintenance).
• Phrase match: 50-200 negatives, reviewed monthly.
• Broad match: 200-1,000+ negatives, reviewed weekly minimum, ideally daily.

If you don't have time to maintain the negative list, don't use the looser match type. Match type and negative discipline are joined at the hip.

Common match type mistakes when launching new campaigns

1. Going broad match from day one because Google recommends it

Google's in-platform recommendations almost always push broad match. They benefit from broader reach (more auctions = more revenue for Google). They don't share your CPA target. Default to phrase, ignore the nudge.

2. Using one match type per ad group then never reviewing search terms

Even on phrase match, the Search Terms report will reveal queries you never wanted to bid on. Weekly search term reviews are non-negotiable for the first 90 days of any new campaign.

3. Mixing match types in the same ad group without bid logic

Putting [plumber london], "plumber london" and plumber london in the same ad group means Google picks which match type wins each auction. You lose the ability to bid differently by intent level. Split match types into separate ad groups (or campaigns for high-spend accounts).

4. Forgetting close variants for exact match

Exact match in 2026 includes plurals, misspellings, paraphrases, and same-meaning queries. If you bid on [plumber london], you're also bidding on "plumbers near london". Plan negatives accordingly.

5. Switching to broad match before Smart Bidding has trained

Broad match without trained Smart Bidding is the single most expensive mistake in new account launches. Wait the 14-30 days. The patience pays for itself many times over.

Industry-specific recommendations

B2B / professional services

Phrase + exact only for the first 90 days. B2B has long sales cycles and low conversion volume - Smart Bidding rarely gets enough signal to make broad match work. Stay tight.

Local services (plumbers, electricians, roofers)

Phrase match dominant, with exact for "[service] [town]" head terms. Broad match works at higher spend levels but requires aggressive geographic and intent negatives.

Ecommerce

Standard Search campaigns: phrase + exact. Most ecommerce volume should be in Shopping or Performance Max, with Search campaigns providing supplementary brand and category coverage.

Lead-gen with high CPA tolerance

Phrase first. Once you have 30+ conversions and Target CPA is trained, broad match testing becomes viable. Insurance, finance, and legal verticals fit here.

Brand defence campaigns

Exact match only. Bid on [your brand] and [your brand reviews] type terms, with broad and phrase explicitly added as negatives elsewhere.

How Ben thinks about match type in the 90-Day Revenue Takeover

In Phase 1 (audit), Ben reviews every existing keyword's match type against its conversion data. In Phase 2 (rebuild), the default rebuild is phrase + exact, with broad match reserved for ad groups that already have 30+ conversions and trained Smart Bidding. Phase 3 introduces broad match testing in controlled cells. Phase 4 monitors search terms weekly and adds negatives ruthlessly.

The result, on average across 250+ accounts: 30-50% reduction in irrelevant traffic within the first 60 days from match type discipline alone, before any bid or copy changes.
