I’ve learned that broad match now operates alongside Smart Bidding. It’s fascinating how drift happens, why it’s important, and how to align performance with genuine intent.
Broad match, once synonymous with “more reach, less relevance,” now depends on a machine learning layer to define relevance.
Over time, Google has nudged us, the advertisers, towards fewer complexities like fewer match types and more automation.
Since July 2024, broad match has become the default for new Search campaigns, signaling a shift in how we ought to think about it.
If you’re stuck in the mindset of broad match being the “loosest match type,” you’re stuck in 2016, and that’s where problems like CPC inflation and irrelevant leads arise.
Today’s broad match works within a system, collaborating with query matching, Smart Bidding, conversion signals, and optional tools like audiences and negatives.
Google leverages broad match as a growth mechanism for Smart Bidding campaigns rather than a solitary reach tactic.
In this article, I explore the changes, Google’s motivations behind them, and safe practices to maintain standards while using broad match.
The real risk with broad match isn’t relevance, it’s direction
Broad match tends to drift rather than fail completely.
With shallow optimization goals, broad match coupled with Smart Bidding can find quick ways to meet them, sometimes resulting in:
- Queries that trigger cheap forms without real sales potential.
- Users who convert but never purchase.
- Leads that look good in Google Ads but don’t end up profitable.
Even when everything seems fine in the interface, the account might drift away from commercial intent.
This illustrates why understanding broad match’s current behavior is crucial.
What broad match actually is now
Broad match no longer stands alone as a keyword setting but works within a larger optimization system.
It’s built to work with Smart Bidding
Google specifies that broad match is intended to run with Smart Bidding, as bidding decisions are now made during auctions using signals like:
- Device
- Location
- Time of day
- Query context
- User behavior
Broad match increases eligible queries. Smart Bidding evaluates which ones merit investment.
Running broad match without Smart Bidding deviates from its intended design.
Google has materially improved broad match matching
Google claims that recent AI enhancements have uplifted broad match campaigns using Smart Bidding by 10%.
This doesn’t imply broad match is inherently safe, but Google feels its matching layer justifies broader use.
It’s no longer positioned as optional
Starting July 2024, new Search campaigns activate broad match by default.
The campaign-level setting enforces broad match when conversion-based Smart Bidding is active, marking a significant paradigm shift.
Why Google wants advertisers to adopt broad match
Google’s rationale is straightforward:
- Search behavior is increasingly unpredictable and long-tail.
- Manual keyword lists fail to keep up with language and intent shifts.
- Machine learning can interpret intent at auction time better than rigid logic.
Google positions broad match as a growth tool for Smart Bidding campaigns, providing algorithms with more opportunities to optimize for conversions.
You might not agree with this philosophy, but when advertising on Google Search, you’re part of this system.
A framework for using broad match without losing control
Broad match expands your reach. Maintaining control requires thoughtful constraints.
Conversion goals that reflect quality, not convenience
Smart Bidding optimizes based on defined conversion actions and values.
If your primary conversions are low-intent, broad match will scale this low intent.
Successful setups often include:
- Optimizing for deeper conversion actions.
- Applying conversion values to identify lead quality tiers.
- Importing offline conversions, like qualifying leads or revenue.
This tackles the issue of associating cheap volume with success.
Intent filters through audience signals
Broad match identifies queries. Audience signals dictate ad visibility for those queries.
Audiences should provide context, not just report data:
- Customer lists favor known buyers.
- Remarketing lists for measured expansion.
- Audience insights to recognize quality-segment correlations.
Even in observation mode, these signals help verify if broad match growth benefits the right areas.
Negative keyword structures that scale
With broad match, negative keywords transform from mere cleanup to structural elements.
Effective accounts often include:
- Account-level shared negative lists for terms like jobs, free, definition.
- Campaign-level exclusions aligned with intent boundaries.
- Regular search term reviews, crucial early on.
Broad match naturally explores, while negatives determine its limits.
Brand controls to protect intent
Google’s brand controls can substantially reduce unwanted behavior in broad match.
These controls include:
- Brand inclusions restrict matching to queries featuring specified brands.
- Brand exclusions prevent matching on certain brand names.
These controls are handy when broad match starts overlapping with competitor intent or misaligned searches.
How broad match succeeds and where it breaks
A sensible rollout usually includes:
- Choosing a campaign with effective tracking and enough conversion volume.
- Aligning Smart Bidding with meaningful outcomes.
- Launching with predetermined negative keywords.
- Frequent search terms reviews in the initial month.
- Verifying lead quality outside Google Ads before scaling.
Broad match has potential and is beneficial if used wisely. However, it isn’t a simple fix.
Failures often occur due to three common mistakes:
- Choosing the wrong conversion to optimize: The algorithm follows your instructions meticulously.
- Lack of a negative keyword system: Unchecked exploration becomes costly.
- Judging success solely by platform metrics: CPC and CPA can look good, while revenue declines.
Broad match is a system, not a setting
Google favors a systemized approach to Search, moving from simple keyword management to a broader strategy.
Control isn’t lost, but shifted.
Successful broad match campaigns are defined by:
- Clear quality definitions.
- Deliberate intent constraints.
- Success measured beyond the interface.
If used judiciously, broad match can reveal new demand opportunities. Casual use, however, might lead you astray.
