Performance Marketing

PMAX
Optimizing budgets for sustainable Lead growth: running over VND 500 million in Paid Media budget a year for B2B audiences - allocated by funnel stage, optimized weekly and measured by Lead quality rather than impressions.
Challenge
Ad budget was spread across many platforms without clear allocation rules. Cost per Lead kept rising while quality did not improve.
Objective
Standardize a shared operating process: budget tied closely to each funnel stage, with every campaign group accountable for exactly one core metric.
Execution
Tiering target audiences by readiness; aligning Content - Creative - Media for each funnel tier; keeping a weekly optimization rhythm.

Optimization focus
01

Budget allocation

Concentrating on the groups with the best performance and cost.
02

Audience strategy

Segmenting by interest level and actual behavior.
03

Campaign structure

Setting up campaigns aligned with each funnel stage.
04

Creative optimization

Testing many different messages and angles.
05

Lead quality

Managing performance by qualified Lead rate rather than CPL.
Budget allocation

Budget split by principle, not evenly

I keep the final say on budget. Spend is allocated precisely by funnel-tier role and actual cost efficiency, rather than following the platform's default recommendations.

01

Budget follows the funnel stage

The conversion tier gets the largest share to secure business KPIs; the upper tiers get enough budget to keep a continuous data feed.
02

Reallocation every two weeks

Campaigns that hold the best cost per Lead (CPL) and qualified Lead rate are immediately prioritized for more budget.
03

Caps for scale-limited groups

Retargeting and CRM Lists are cheap but limited in size. Spending caps prevent Ad Fatigue, and the surplus goes into expanding new audiences.
Audience

Tiering audiences by readiness

The closer someone gets to a purchase decision, the more specific the message must be and the more each user is worth investing in. The four audience tiers below run in parallel, each with its own goal.
01 · Lookalike Audience
Expanding from the best-converting customer lists to find users with similar profiles and behavior.
02 · Interest & Behavior
Precise targeting by industry behavior, in-depth interests and identifying traits of B2B decision-makers.
03 · Remarketing Audience
Re-engaging users who interacted with the website, Fanpage or watched videos but haven't signed up yet.
04 · Customer List
Nurturing and leveraging existing customer data, prioritizing those with potential for contract expansion (Up-sell /Cross-sell).
Width shows audience size; color depth shows conversion readiness. The deeper into the funnel, the smaller the audience but the higher the budget per person.
Creative

The system behind it

Three models behind every decision above

The budget split, audience tiering and Creative selection above are not gut-feel decisions. They all run on a standardized system made up of the 3 core models below.
01

Full Funnel Media Strategy

Budget is allocated across 4 clear funnel tiers, each accountable for exactly one target metric:

Expanding reach

Measured by Reach and CPM.

Driving first engagement

Measured by CTR and CPC.

Nurturing those not yet ready

Time-sequenced remarketing, measured by return rate.

Generating qualified Leads

Measured by CPL and qualified B2B Lead rate.
Allocation rule
Each funnel tier is accountable for exactly one metric. Campaigns that miss KPI lose budget, with no cross-subsidizing.
02

Creative Testing Model

Creative performance is validated with data, not gut feel. Each ad is scored against 5 standardized criteria with specific recommendations for adjustment.
