01 Nov How to structure Performance Max in 2026

Performance Max works best when you run fewer campaigns with stronger controls. Structure for intent and margin, keep brand traffic ring fenced, build asset groups that reflect buyer jobs, then guide automation with value rules and clean feeds. This is the 2026 setup our PPC teams use.

What a good Performance Max structure looks like

• Fewer campaigns that map to product lines, margins, and markets
• Clear brand protections so PMax does not cannibalise Search brand
• Asset groups aligned to customer jobs and categories, not random themes
• Value rules and data signals that bias bidding toward profit

When to split campaigns

Split when it changes bidding or budget

• Margin tiers: high, mid, low
• Product line or service line: clear commercial differences
• Country or language: currency, stock, creative and policy differences
• Lifecycle goals: acquisition vs retention where offers differ
• Stock or seasonality: items with rapid availability swings

Do not split for vanity

• Colour, tiny category differences, or small audiences
• Channel preferences like Video vs Shopping inside PMax

A starter map

• 1 campaign for high margin lines
• 1 campaign for mid margin lines
• 1 campaign for low margin lines if volume justifies it
• Optional 1 campaign for retention and CRM seeded audiences

Brand exclusions and guarding Search brand

Why to protect brand

Brand clicks are cheap and convert well. If PMax hoovers brand, you lose control and skew reporting.

How to guard brand in 2026

• Add brand exclusions at campaign level
• Keep a separate Search brand campaign with exact and phrase
• Use URL expansion set to Only send traffic to specific URLs where needed
• Exclude brand terms and navigational URLs from listing groups where they sneak in
• Monitor search term insights weekly and expand the exclusions list

When to allow brand

• For new launches where you need speed and broad coverage
• In markets with many misspellings where your Search list is thin
• For pure acquisition where you exclude existing customers with Customer Match

Asset strategy that actually lifts performance

Build asset groups around jobs to be done

Create groups that match the problem the user is trying to solve, not just a product name.

• Problem solver
• Comparison shopper
• Price sensitive buyer
• Premium buyer

Creative checklist per asset group

• 5 to 7 headlines that tell the benefit and the next step
• 3 to 5 long headlines that add proof or detail
• 4 descriptions with one clear CTA
• 10 to 15 images that cover product, context, and proof
• 3 to 5 short videos cut to 6, 10, and 15 seconds
• Brand assets set correctly so you control logo and colours

Feed hygiene for Shopping supply

• Titles with problem plus product plus key attribute
• Fresh GTINs, clean MPNs, complete attributes
• Use product types and custom labels to map margin and seasonality
• Exclude junk variants and out of stock items daily

Audience signals that help, not hinder

• Customer Match lists for VIPs, recent buyers, churn risks
• In market and affinity themes related to the job, not brand vanity
• Data signals from GA4 events like qualified lead or high value purchase

Value rules and bidding for profit

Why value rules matter

PMax optimises to your goal. If revenue is not the best proxy for profit, you must feed it better signals.

Practical value rules

• Boost value by margin group, for example +40% high margin, neutral mid, −30% low
• Boost by stock status or fulfilment speed
• Lower value for high return items or high cost shipping
• For lead gen, set conversion values by CRM stage, not one flat number

Targets and budgets

• Start with tROAS or tCPA based on history and goal
• Give each campaign enough budget to exit the learning dip
• Use seasonality adjustments only for short, predictable bursts
• Keep shared budgets off unless you need to protect a hard cap

Controls you should always use

Inventory and placements

• Exclude mobile apps and sensitive categories where they waste spend
• Use location targeting set to Presence, not Presence or interest
• Add placement exclusions for parked domains or poor inventory

URL expansion discipline

• Default to Send traffic to the most relevant URLs unless your site structure is messy
• Switch to Only send to provided URLs for tightly controlled launches and tests

Negative keywords and search themes

• Maintain account level negatives for known time wasters
• Feed search themes that reflect profitable non brand intent
• Review search term insights and update weekly

Reporting that leaders believe

Group by what matters

• Segment by margin tier, product line, country
• Report on new vs returning where you run retention
• Split out brand influenced segments where you allow brand

Use the right conversion set

• Include enhanced conversions and offline imports
• Remove soft metrics that inflate ROAS without profit
• Align GA4 and Ads with the same primary conversions

Example structures by business type

Ecommerce

• Campaign 1: High margin products, brand excluded, value rules +40%
• Campaign 2: Mid margin products, brand excluded, neutral value rules
• Campaign 3: Low margin or clearance, tight tROAS, value rules −30%
• Asset groups per job: problem solver, comparison, premium, price sensitive
• Customer Match: VIP upsell, recent buyers, exclude current buyers

Lead generation

• Campaign 1: Acquisition, value by CRM stage
• Campaign 2: Upsell or cross sell to customers, exclude prospects
• Asset groups by vertical or problem set
• Import offline conversions with stage and value

SaaS

• Campaign 2: Expansion and upsell, exclude active contracts
• Value rules by plan tier and predicted LTV
• Asset groups for pain points, integrations, and security proof

Workflow and governance

Weekly

• Check search term insights, add brand or junk exclusions
• Rotate weak assets, ship one new video per top group
• Review impression share and budget caps

Monthly

• Rebalance budgets by margin and stock
• Refresh feed titles and promote seasonal labels
• Validate value rules against finance actuals

Quarterly

• Structure review to remove unneeded splits
• Experiment with a holdout on brand exclusions to confirm cannibalisation risk
• Run a geo split to prove any big strategy change

30 day build plan

• Week 1: Audit current structure, map margin tiers, gather assets
• Week 2: Rebuild into 2 to 4 campaigns, set brand exclusions, load value rules
• Week 3: Launch with conservative targets, monitor search term insights daily

FAQ

How many PMax campaigns should I run

Most accounts perform with 2 to 4 campaigns mapped to margin and line. Add more only when budget, language, or lifecycle goals demand it.

Should I ever allow brand in PMax

Only when you have a clear reason like a launch or messy misspellings. Keep a clean test and compare against a protected brand setup.

Do audience signals limit reach

No. Signals are hints, not hard targets. Use them to point automation at profitable intent, not to wall it in.

How often should I rotate assets

Every 2 to 4 weeks. Replace low performers, keep winners, then test new hooks and formats.

What if I cannot set value rules

Start with simple margin labels and tROAS by campaign. Move to value rules once finance confirms the ranges.

Key takeaways

• Fewer campaigns with clear splits beat sprawling setups
• Protect brand so Search brand keeps control
• Build asset groups around buyer jobs and keep feeds spotless
• Use value rules to push bidding toward profit
• Review insights weekly and trim waste before you add more structure
