Google Ads account structure: campaign consolidation, theme grouping, and when to segment

Google Ads structure is a control surface for budget, bidding, and targeting, not a template to copy. Google’s current documentation favors consolidation with Smart Bidding, and Temper And Forge’s practice is to start from that guidance, then adjust structure based on budget, catalog strategy, and acquisition goals. For bidding mechanics see our Smart Bidding lane, and for budget sizing see our Google Ads budget methodology.

Account layers, settings scope, and hard limits

Per Google’s documentation, a Google Ads account has 3 structural layers: the account, campaigns, and ad groups. The account holds login and billing. Campaigns own budget and settings that determine where ads can appear. Ad groups hold sets of similar ads and keywords.

Campaign-level settings include location, language, and network settings. Keywords and ads live at the ad group level. This split is the structural reason you sometimes must create a separate campaign: when those campaign-level settings genuinely need to differ.

Google also documents explicit structural limits. These matter when you plan large builds or consolidations.

Manager accounts (often called MCCs) sit above this structure. Google’s help pages state that manager accounts provide one login across linked accounts and cross-account reporting, and that an individual account can be managed by at most 5 manager accounts.

How Google’s current guidance differs from hyper-segmented builds

Older advice often pushed extreme granularity, such as single keyword ad groups, with the belief that more segmentation meant more control and better performance. Google’s current guidance is the opposite: Google strongly recommends consolidating your campaign structure so Smart Bidding can access more traffic and conversion data.

Google’s “ABCs of Account Structure” guidance states that match-type variants of a themed ad group should move into one ad group, and that you should rely on broad match rather than duplicating the same keyword across match types. The same guidance advises removing device-segmented campaigns because Smart Bidding already accounts for device in bidding decisions.

Google’s setup best practices say each campaign should have one objective, and that keywords aimed at clicks and keywords aimed at conversions belong in separate campaigns. Google also states that separate campaigns are justified mainly by budget, bidding, or location needs, not by a desire for more knobs for their own sake.

For ad groups, Google recommends organizing by category or business goal, often mirroring the website’s structure. That is a themed approach, not a SKAG pattern. Google’s help pages also state that the current consolidation guidance is published under current names only, and that no current page documents a hard keywords-per-ad-group rule.

Why match-type and device splits hurt with Smart Bidding

Under Smart Bidding, the algorithm prices each auction using many signals, including device. Google’s “ABCs of Account Structure” guidance explicitly says that Smart Bidding already accounts for device in bidding decisions and advises removing device-segmented campaigns. Keeping separate mobile and desktop campaigns fragments traffic and conversion data that could otherwise train one bidding model.

Google also states that duplicating the same keyword across match types segments the data Smart Bidding works with. When you split the same intent across multiple ad groups or campaigns, each entity sees fewer impressions and conversions, which restricts Smart Bidding’s ability to find conversions at your target.

Google’s broader AI guidance strongly recommends consolidating your campaign structure and notes that the more traffic is split up, the more Smart Bidding is restricted from finding conversions at target. Google documents shared budgets plus portfolio bid strategies as the best practice pairing for this consolidated approach, covered in our Smart Bidding lane.

Temper And Forge’s framework for campaign count and segmentation

Temper And Forge’s position is that there is no one-size-fits-all campaign structure because structure is contingent on too many factors to template. In client work, the honest driver list is budget first, then (for ecommerce) catalog size and whether the client wants to push the full catalog versus individual SKUs, and (for B2B) the acquisition strategy and the intent verticals of who the client wants to reach.

Budget is the first gate. Temper And Forge’s practice is that a small conservative daily budget does not get split between multiple campaigns, because splitting starves everything. This aligns with Google’s statement that splitting traffic restricts Smart Bidding’s data and performance.

For ecommerce, Temper And Forge looks at catalog size and whether the goal is full-catalog coverage or emphasis on specific SKUs. For B2B, structure follows acquisition strategy and the intent verticals that map to the client’s real target audiences. Cost per unit or cost per service, total budget, and the business model all feed the decision.

The structural question Temper And Forge asks is never “what does the template say” but “what does this budget, this catalog, and this acquisition strategy need.” Consolidation is the default, and segmentation has to earn its place by tying to different budgets, bidding goals, or locations, in line with Google’s own justification for separate campaigns.

When individual-SKU or single-product campaigns make sense

Google’s documentation does not prescribe SKU-level campaign rules, but Temper And Forge’s practice is clear. For ecommerce, catalog size and SKU strategy are core inputs. Temper And Forge sees independent SKU campaigns perform well when the assets are strong, for subscription products and for single physical-product SKUs.

In these cases, a separate campaign is justified because the SKU has distinct economics, creative, and often a different objective or budget priority. This aligns with Google’s guidance that separate campaigns are mainly justified by budget or bidding needs. The rest of the catalog can sit in more consolidated campaigns, often with shared budgets.

Structuring B2B accounts around intent verticals

For B2B, Temper And Forge structures around acquisition strategy and intent verticals. An intent vertical is a cluster of queries and audiences that represent a distinct way someone might buy from the client, such as different industries or use cases.

Google recommends organizing ad groups by category or business goal, which maps cleanly to intent verticals in B2B. Campaigns then group these verticals where they share budget and bidding objectives, and split when they require different budgets, bid strategies, or locations, consistent with Google’s account setup best practices.

This approach avoids the legacy pattern of splitting for its own sake, such as device splits or SKAGs, which Google now warns against under Smart Bidding. Instead, segmentation earns its place when it reflects real differences in objectives or economics between intent verticals.

Decision rules for when a separate campaign is justified

Google’s setup guidance states that each campaign should have one objective, and that separate campaigns are mainly justified by budget, bidding, or location needs. That gives a clear decision rule: create a new campaign when you need a different budget, a different bidding strategy or objective, or different location or language settings.

Google’s help pages also state that location, language, and network settings live at the campaign level, while keywords and ads live at the ad group level. If two groups of queries can share these campaign-level settings and objective, they belong in the same campaign, with separate ad groups organized by theme or business goal.

Temper And Forge layers its own practice on top of this. With small conservative budgets, Temper And Forge keeps campaign counts low so each campaign has enough daily budget and data. As budgets and catalog or intent complexity grow, new campaigns are added only when they are tied to distinct budgets, SKU pushes, or B2B intent verticals that require different acquisition strategies.

Temper And Forge’s practice is to treat consolidation as the default, in line with Google’s strong recommendation to consolidate so Smart Bidding can work with more data. Segmentation is introduced only when it is justified by budget, bidding, or location differences, or by a specific SKU or intent vertical with distinct economics and creative.

Temper And Forge’s practice is that there is no one-size-fits-all campaign structure. Budget comes first, then catalog size and SKU push strategy for ecommerce, and acquisition strategy and intent verticals for B2B, with consolidation as the default and any segmentation required to earn its place.
