The three match types, in their current form
There used to be four. Broad match modifier — the +running +shoes syntax — was folded into phrase match in February 2021 and no longer exists. What's left is three settings, written as punctuation around the keyword.
| Match type | How you write it | What it can match |
|---|---|---|
| Broad | running shoes | Anything Google judges related — synonyms, related searches, and intent inferred from your landing page, your other keywords and the user's recent activity. |
| Phrase | "running shoes" | Searches that include the meaning of your keyword, with words before or after. Absorbed everything broad match modifier used to do. |
| Exact | [running shoes] | Searches with the same meaning or same intent. Includes reordering, misspellings, plurals, abbreviations and implied words. |
Why exact match stopped being exact
Close variant matching started small — misspellings and plurals, which nobody objected to. It then widened to stemming, abbreviations and accents, and finally to same-meaning queries. Today [running shoes] can serve on "shoes for running", "jogging shoes" and "buy running footwear", because Google reads those as the same intent.
That's usually fine and occasionally expensive. The classic failure is a brand term: [acme accounting software] can pull in "accounting software like acme", which is a competitor-shopping query you're now paying to lose. You only find these in the search terms report, which is why the audit below is not optional.
Match type and Smart Bidding are now one decision
Broad match is designed to be paired with Smart Bidding. The logic is honest enough: broad casts wide, and the algorithm bids down or not at all on queries it expects to convert badly. Take away the algorithm and you've kept the casting and lost the correction.
So: broad plus Target CPA or Target ROAS with real conversion history is a legitimate discovery tool. Broad plus manual CPC, or broad plus a conversion action that fires on every page view, is a wider net over the same small pond.
Smart Bidding also needs volume to learn from. If the account sees a handful of conversions a month, there's nothing for it to correct with, and broad match behaves exactly as badly as its reputation suggests.
A match type plan for budgets under ₹1 lakh a month
Small budgets can't fund exploration. At ₹40,000–₹1,00,000 a month, every wasted click is a real percentage of the account. Run it in this order.
- Ship a negative keyword list before day one. Jobs, salary, free, download, course, PDF, "kaise", and any competitor whose customers you don't want to pay to entertain.
- Start exact on the ten to twenty queries you already know convert — from Search Console, from your sales calls, from your CRM.
- Add phrase for the same themes once exact has four to six weeks of data and you know your real cost per click.
- Only then test broad, in its own campaign, with its own budget cap and Smart Bidding attached. Never inside the campaign that's already working.
- Read the search terms report weekly for the first month, then fortnightly. Add negatives every single time.
Auditing match types with the search terms report
The search terms report shows the queries that actually triggered your ads, next to the keyword that caught them. Sort by cost, descending. Anything expensive and irrelevant becomes a negative today; anything cheap and converting gets promoted to its own exact-match keyword.
One caveat: the report doesn't show every query. Google withholds terms too few people searched, so a slice of your spend sits in an unattributable bucket — and that slice is usually larger on broad than on exact. Another quiet argument for keeping broad in its own campaign.
It's also the best keyword research file you'll ever get, which is why we read it alongside organic. See how we run performance marketing.
