How to Structure a Google Ads Search Campaign by Intent

Open most Google Ads Search accounts and the campaign structure tells you what the business sells: one campaign per product line, one ad group per feature, keywords grouped by topic. What it almost never tells you is how differently a person searching "buy project management software" behaves compared to one searching "what is project management software." Both queries might land in the same ad group if the structure was built around subject matter instead of intent, and that's exactly how budget ends up spread evenly across clicks that were never equally likely to convert. For background on what the platform itself covers, from bidding strategies to Performance Max, see our full Google Ads profile. Below is a structure built around intent instead, along with the match type and negative keyword discipline that keeps it working as it scales.

Step 1: Split Campaigns by Intent Tier, Not Just by Product

Before touching keywords or ad copy, separate search intent into three broad tiers and give each one its own campaign, not just its own ad group. High-intent transactional queries, the ones carrying "buy," "price," "demo," "near me," or a specific product or model name, represent someone close to a decision and deserve the most aggressive bids and the tightest budget protection. Comparison and consideration queries, things like "best," "vs," "alternative to," or "reviews," sit a step earlier; the searcher knows the category and is actively narrowing options, but hasn't committed. Informational queries, "what is," "how does," "why," sit earliest in the funnel and convert at a meaningfully lower rate, if the goal is a purchase or a demo request rather than a content download.

Separating these into distinct campaigns, rather than blending them into shared ad groups, matters for a concrete reason: campaign-level budgets and bid strategies in Google Ads apply at the campaign, not the ad group, level. If a high-intent transactional campaign and an informational campaign share one budget, a surge in cheap informational clicks can quietly starve the transactional campaign of spend on a day when it would have converted best. Separating them means budget allocation is a deliberate decision, not an accident of which query happened to get more impressions that day.

Step 2: Build Ad Groups Around Tightly Themed Keyword Clusters

Within each intent-tier campaign, ad groups should be built around tightly themed keyword clusters, generally somewhere between three and ten ad groups per campaign, each one specific enough that a single, focused ad can speak directly to it. An ad group mixing "project management software," "task tracking app," and "team collaboration tool" is too broad for one ad to feel relevant to all three; splitting them into separate ad groups lets the headline and description mirror the exact phrase a shopper typed, which is still one of the more reliable ways to lift quality score and click-through rate. This is also where most accounts drift over time: an ad group that starts tightly themed accumulates loosely related keywords added on a whim, and six months later it's carrying search terms that have nothing to do with the original ad copy. A quarterly pass to re-tighten ad group themes catches that drift before it costs meaningful spend.

Step 3: Choose Match Types Around What Actually Supports Broad Match

Match type strategy is where the most Search budget gets wasted, and the common advice, "just use broad match, Google's algorithm has gotten smarter," is only half true. Broad match paired with Smart Bidding and clean conversion tracking has become one of the more scalable setups in Search, but it only works well when four things are actually in place together: accurate conversion tracking, a Smart Bidding strategy actively optimizing toward that conversion action, a substantial negative keyword list, and enough monthly conversion volume, generally cited around thirty or more conversions a month, for Smart Bidding to have something real to learn from. Turn broad match on without those four in place and it becomes exactly the trap advice warned against for years: an automated system spending the same budget against a much wider, less qualified set of queries with nothing constraining where it goes.

The practical rule that follows is straightforward. In the high-intent transactional tier, where a wrong click is expensive and volume may not yet support Smart Bidding's learning requirements, phrase match or a mix of phrase and broad match with tight negatives gives more control while the campaign proves itself. Once that campaign is generating steady conversion volume and a Smart Bidding strategy like Target CPA or Maximize Conversions has enough data to optimize against, broad match becomes worth testing incrementally, one ad group at a time, watching the search terms report closely rather than flipping match type across the whole campaign at once. In the informational tier, where the cost per click is typically lower and the goal is volume and reach rather than precision, broad match under Smart Bidding tends to make sense earlier, since the downside of an imprecise match is smaller.

Step 4: Build Negative Keyword Hygiene Into a Weekly Routine, Not a One-Time Setup

A negative keyword list built once during initial setup and never revisited is one of the most common reasons a well-structured account still leaks budget six months later. Negative keywords work at two levels that serve different purposes: account-level negative lists block entire themes, terms like "free," "jobs," "cheap," or "DIY" that signal a searcher outside your buying intent, across every campaign at once, while campaign- and ad-group-level negatives keep query overlap from happening between your own tiers, so a transactional campaign doesn't accidentally compete against your own informational campaign for the same click. Reviewing the search terms report weekly, not monthly, is what keeps this list current; the goal isn't to micromanage every match type decision, it's to catch new negative candidates and genuine new keyword opportunities while they're still cheap to act on, rather than after a few thousand dollars have already gone toward the wrong query.

It's worth being disciplined about the other failure mode too: negating too aggressively. Blocking too broadly starves the campaign of the query volume and conversion signal that Smart Bidding needs to keep learning, and can suppress legitimate traffic along with the genuine junk. The accounts that get the most value from negative keywords tend to run substantially larger lists, several hundred terms built up over time, than the twenty or thirty most accounts stop at, but they get there gradually through weekly review, not through one aggressive negation pass.

Step 5: Let Performance Max Complement This Structure, Not Replace It

Performance Max is not a reason to abandon a well-structured Search campaign, even though it's tempting to treat one AI-driven campaign type as a replacement for the work above. Performance Max runs across Search, Display, YouTube, Gmail, Discover, Maps, and Shopping inventory from a single campaign, optimizing toward a goal with less manual control over placement and keyword-level targeting than a dedicated Search campaign gives you. Google's own auction logic favors the more specific match when the two campaign types could both serve the same query, an exact-match keyword in a Search campaign takes priority over Performance Max for that same search. That's the practical reason the two are meant to run together rather than compete: Performance Max earns its keep driving broader reach and discovery across channels a keyword-based Search campaign can't touch, while a well-structured Search campaign keeps capturing the highest-intent queries with the precision, ad copy control, and negative keyword protection that Performance Max doesn't offer at the keyword level. Running both without any coordination, though, risks the same budget competing against itself; keep the intent tiers and negative lists in your Search campaigns tight, and audit Performance Max's search term insights periodically to see whether it's picking up queries that belong back in a Search campaign with tighter control.

What This Structure Actually Buys You

Built this way, a Search account stops being a keyword list organized by product catalog and becomes a system that spends differently depending on how close a searcher actually is to converting: separate campaigns and budgets by intent tier, ad groups tight enough for genuinely relevant ad copy, match type decisions tied to whether Smart Bidding actually has what it needs to perform well, a negative keyword list maintained weekly instead of set once and forgotten, and a Performance Max campaign coordinated with Search rather than left to compete against it. None of this requires a bigger budget to see the benefit; it requires the existing budget to stop being spread evenly across queries that were never equally valuable in the first place.
