How to Combine Broad Match with Negatives in Google Ads (Step-by-Step)

TL;DR: Broad match gives Google's algorithm maximum flexibility to find relevant searches, but without a solid negative keyword strategy, it burns budget fast. The real power comes from pairing broad match keywords with a well-maintained negative keyword list, so you capture high-intent traffic without funding irrelevant clicks. This guide walks you through exactly how to do that, step by step — from auditing your search terms to building a weekly review workflow that keeps things under control over time.

If you've ever turned on broad match and watched your impressions explode while conversions stayed flat, you already know the problem. Broad match is not inherently bad. In most accounts I audit, the issue isn't the match type itself — it's that nobody set up the guardrails. No negatives. No review cadence. No system.

What follows is the workflow I'd walk through with any account, whether you're a solo advertiser managing one campaign or an agency juggling twenty client accounts. You'll learn how to audit what broad match is actually triggering, how to build and apply negatives systematically, and how to maintain the whole system over time without it becoming a full-time job.

Step 1: Understand What Broad Match Actually Does Before You Touch Anything

Before you start adding negatives or restructuring campaigns, it's worth making sure your mental model of broad match is current. A lot of PPC practitioners are still working with a 2019 understanding of how it behaves, and that leads to bad decisions.

In 2025-2026, broad match is not just synonym expansion. It uses Smart Bidding signals, your landing page content, other keywords in the ad group, and audience data to determine which queries to enter. Google's algorithm is essentially asking: "Given everything I know about this account, this user, and this keyword — is this search a good match?" That's a fundamentally different mechanism than the old keyword-to-synonym matching.

This is why broad match performs much better when paired with Smart Bidding (Target CPA or Target ROAS). Without it, broad match is flying blind. With it, the algorithm can use conversion data to self-correct and prioritize queries that are more likely to convert. The negative keyword list is what keeps it from going completely off the rails in the meantime.

When broad match makes sense: New campaigns where you're exploring demand and don't yet know which exact queries convert. Accounts with enough conversion data for Smart Bidding to work effectively. Situations where you want to discover long-tail queries you wouldn't have thought to bid on.

When broad match is risky: Tight ROAS campaigns where every dollar needs to work hard. Accounts with thin conversion data. Campaigns in niche verticals where off-topic matches are common and costly.

The ideal setup is: broad match keyword + Smart Bidding + a strong, maintained negative keyword list. Think of it as a controlled discovery engine, not a free-for-all. The negatives are what turn it from reckless into strategic.

Step 2: Audit Your Search Terms Report Before Adding Any Negatives

Here's where most people go wrong: they add negatives based on intuition rather than data. Before you build a single negative keyword, pull the Search Terms Report and see what's actually happening.

To access it: go to your campaign in Google Ads, then navigate to Insights & Reports > Search Terms. Note that the UI layout can vary slightly depending on your account view, and there's typically a data delay of a day or two. Also worth knowing: Google withholds some search terms for privacy reasons, so you're not seeing 100% of what triggered your ads — but you're seeing enough to work with.

Once you're in the report, here's what to look for:

Irrelevant queries: Searches that have nothing to do with your product or service. These are your clearest negatives.

Competitor brand terms: If you're not running a competitor campaign intentionally, these are usually worth blocking — especially if they're spending budget without converting.

Wrong-intent searches: Informational queries like "how to do X" or "what is X" when you're selling a solution to X. These users aren't ready to buy.

Zero-conversion, high-cost terms: Filter by cost (descending) and look for terms that have spent significant budget with zero conversions. These are your highest-priority cuts.

A practical filtering approach: set the date range to the last 30-90 days, sort by cost descending, and work through the top 50-100 terms. Categorize each one into three buckets:

Keep: High-intent terms that are converting or look like they should. Consider adding these as exact or phrase match keywords for more bidding control.

Block: Clear irrelevants, competitor terms you don't want, wrong-intent searches. These become your negatives.

Monitor: Ambiguous terms that have some impressions but no clear verdict yet. Leave them for now and revisit in your next review.

If you want to skip the spreadsheet export step entirely, tools like Keywordme let you do this categorization directly inside the Search Terms Report with one-click actions. You can add negatives, promote keywords, and flag terms without leaving the Google Ads interface — which makes the whole audit significantly faster, especially if you're doing this across multiple campaigns.

Step 3: Build Your Initial Negative Keyword List from Search Term Data

Now you're ready to build your first negative list. The goal at this stage is to create a solid foundation — not to block everything that looks slightly off. Over-blocking at the start is a real risk, and it can suppress the very discovery that makes broad match valuable.

A commonly recommended starting point among PPC practitioners: 15-30 high-confidence negatives before you launch or expand a broad match campaign. These should be terms you're certain you don't want — not borderline cases.

Campaign-level vs. ad group-level negatives: Campaign-level negatives apply to every ad group within the campaign. Use these for broad exclusions that apply universally — competitor brands, irrelevant verticals, wrong geography. Ad group-level negatives are more surgical — use them when you need to prevent a specific term from triggering a specific ad group, without blocking it everywhere.

Pattern-based negatives vs. one-offs: Pattern-based negatives are where you get leverage. Instead of blocking individual irrelevant queries one at a time, identify the modifier that makes them irrelevant. Common patterns include:

Informational intent modifiers: "free", "DIY", "how to", "tutorial", "guide", "what is", "definition"

Wrong-stage modifiers: "jobs", "career", "salary", "internship" (if you're selling a product, not hiring)

Wrong geography: Specific city or country names if you only serve certain areas

Competitor brand names: If you're not running conquest campaigns intentionally

Group your negatives into themed lists so they're easier to manage and audit later. Four useful categories: brand exclusions, informational intent, wrong product or service, wrong geography.

Shared negative keyword lists vs. campaign-specific lists: If you're an agency managing multiple campaigns or clients with common exclusions, shared negative lists are a significant time-saver. You build the list once, apply it across campaigns, and update it in one place. For example, a shared "competitor brands" list or a "informational intent" list that applies across all client campaigns in a vertical. Campaign-specific negatives are better for exclusions that are unique to a single campaign's context.

The mistake most agencies make is building negatives campaign by campaign without ever creating shared lists. You end up with the same exclusions duplicated across dozens of campaigns, and when you need to update them, it's a manual nightmare.

Step 4: Apply Match Types to Your Negatives Strategically

Negative match types are one of the most misunderstood parts of Google Ads. They behave differently from positive match types, and the differences matter a lot in practice.

Here's how each one actually works:

Negative broad match: Blocks queries that contain ALL words in your negative keyword, in any order. It does NOT block partial matches. So if your negative is "free trial", negative broad match would block "free software trial" but not "free software" (because "trial" isn't present). This is more permissive than most people expect.

Negative phrase match: Blocks queries that contain the exact phrase in that order. If your negative is "free trial", it blocks "free trial software", "get free trial", and "free trial for teams" — but not "trial free" (wrong order). This is the most intuitive and the most useful for most situations.

Negative exact match: Only blocks queries that exactly match the negative keyword, nothing more. If your negative exact is [free trial], it blocks only searches for "free trial" — not "get a free trial" or "free trial software".

The common mistake is using negative broad when you should use negative phrase. Negative broad sounds like it would block the most, but because it requires ALL words to be present, it can actually be less effective than phrase match for blocking specific problem queries.

A practical example: you're selling a paid project management tool and you want to block searches from people looking for free options.

Adding "free" as a negative broad match blocks any query containing the word "free" — which might be appropriate if you want to block all free-intent searches broadly. But it could also block queries like "free up team bandwidth with project management software", which might be a legitimate prospect.

Adding "free trial" as a negative phrase blocks queries containing that specific phrase in order — more targeted, less collateral damage.

Adding [free project management] as a negative exact only blocks that exact query. Use this when you want surgical precision — for example, protecting a branded term or preventing cross-contamination between specific ad groups.

The practical default for most campaigns: start with negative phrase match. It's the right balance between coverage and precision. Use negative exact for ad group isolation and cross-contamination prevention. Use negative broad sparingly and only when you're confident you want to block any query containing those words.

Step 5: Set Up a Weekly Search Term Review Workflow

Broad match is not a set-it-and-forget-it match type. This is the part most advertisers skip, and it's why broad match gets a bad reputation. The match type isn't the problem — the lack of maintenance is.

The core workflow is what PPC practitioners often call "mine and refine": broad match surfaces new queries, you mine those queries for winners and losers, and you refine with negatives and keyword promotions. Then the cycle repeats. Over time, the campaign gets smarter and more efficient because you're continuously feeding it better signal.

A weekly cadence works well for most active campaigns. Here's what a 20-minute weekly review looks like in practice:

1. Open the Search Terms Report and filter by the last 7 days.

2. Sort by cost descending — start with where the money went.

3. Work through the top 10-20 terms and categorize: keep, block, or monitor.

4. Add blocks as negatives immediately (campaign-level or ad group-level as appropriate).

5. Flag any high-performing terms for keyword promotion (covered in Step 6).

6. Note any patterns in what's triggering — if you're seeing a lot of informational queries, add a pattern-based negative for that intent modifier.

The mistake most agencies make is doing this monthly or quarterly. By then, you've wasted significant budget on terms that a weekly review would have caught in the first week. For high-spend campaigns, consider doing this twice a week. Understanding how to reduce wasted ad spend with negatives is what separates accounts that scale efficiently from those that bleed budget indefinitely.

If you're managing multiple campaigns or client accounts, the time adds up fast. This is exactly where Keywordme earns its keep: it lets you run this entire review workflow directly inside the Google Ads Search Terms Report. One-click negative adds, bulk editing, and keyword clustering without exporting to a spreadsheet or switching to a third-party dashboard. For agencies doing this across ten or twenty accounts, that time saving compounds significantly.

Step 6: Promote High-Performing Search Terms to Exact or Phrase Match Keywords

This is the step that separates a mature keyword strategy from a perpetual broad match experiment. When broad match discovers a query that converts consistently, you should "graduate" it to a tighter match type so you can control the bid more precisely.

Think of it this way: broad match is your discovery layer. Exact and phrase match are your performance layer. The goal is to use broad match to find what works, then lock in your best performers so you can bid on them with full control. This approach is at the heart of using match types in a keyword funnel — each tier serves a distinct purpose in your overall campaign architecture.

The criteria for promotion: A search term that has converted multiple times at an acceptable CPA (or ROAS, depending on your goal) is a strong candidate. There's no universal conversion threshold — it depends on your account's conversion volume and the cost of the keyword — but a commonly used heuristic is two or more conversions at or below your target CPA.

The promotion workflow:

1. Identify the converting term in your Search Terms Report.

2. Add it as an exact match or phrase match keyword in the relevant ad group (or a new ad group if the intent warrants its own creative and bid).

3. Optionally, add the exact term as a negative to the broad match ad group to prevent the two keywords from competing against each other (cannibalization).

On that last point: there's some debate in the PPC community. Some practitioners add the exact term as a negative to the broad match ad group as a standard step. Others rely on Google's ad rank system to serve the most relevant ad and don't bother with the negative. Both approaches are used in practice. If you're seeing clear cannibalization in your auction insights or performance data, the negative is worth adding. If things look clean, you may not need it.

Ad group structure consideration: Should you add the promoted keyword to the existing ad group or create a new one? If the search term's intent aligns closely with the existing ad group's theme and ads, add it there. If it represents a meaningfully different intent or product angle, a new ad group gives you cleaner creative control and better quality score potential.

This "mine and promote" loop is what makes a broad match strategy compound over time. Your exact and phrase match portfolio grows with validated, converting terms — and your broad match continues discovering new ones.

Putting It All Together: Your Broad Match + Negatives Checklist

Here's a quick-reference summary of the full workflow:

1. Understand the match type: Broad match + Smart Bidding + negatives = a controlled discovery engine. Without Smart Bidding and negatives, broad match is high-risk.

2. Audit your Search Terms Report first: Filter by cost, sort by spend, and categorize terms into keep, block, or monitor before adding a single negative.

3. Build a structured negative list: Start with 15-30 high-confidence negatives. Use pattern-based exclusions. Organize into themed lists. Use shared lists for common exclusions across campaigns.

4. Apply the right negative match types: Default to negative phrase match. Use negative exact for surgical ad group isolation. Use negative broad carefully and intentionally.

5. Run a weekly review: 20 minutes per week, filter by last 7 days, act on top 10-20 terms. This is the maintenance that makes broad match work over time.

6. Promote winners to exact or phrase match: Graduate converting search terms to tighter match types for bidding control. Add them as negatives to broad match ad groups if cannibalization is a concern.

The core principle: broad match is a discovery tool, negatives are the guardrails. You need both. And the system compounds — the more you refine, the better your broad match performs, and the stronger your overall keyword portfolio becomes.
