Request a tailored quote for portfolio bid strategy consulting aimed at reducing CAC and improving revenue attribution across Google Ads portfolios.
Modular pricing for discovery, setup, and monthly optimization.

Server-side tracking and GA4 modeling to improve conversion fidelity.
Request a quote for portfolio bid strategy consulting services when you want a structured approach to manage automated bidding across multiple campaigns, channels, or account segments. Portfolio bidding aligns campaign objectives (ROAS, CPA, conversions) across a collection of campaigns, giving you centralized control over budget allocation and performance goals. Prebo Digital focuses on revenue impact, attribution accuracy, and CAC reduction rather than vanity metrics.
Typical clients requesting a portfolio bid strategy quote include US-based Shopify or WooCommerce stores with $50K+ monthly ad spend, B2B SaaS companies running multi-funnel paid search and display, and performance marketers managing cross-product portfolios. Examples below use US-dollar estimates and scenarios to keep recommendations practical and region-specific.
Quotes are based on a modular scope: discovery, strategy design, implementation, testing & optimization, and reporting. Each module is sized by account complexity and data maturity. A typical starter quote for medium complexity accounts (multiple campaigns, conversion types, and server-side tracking) ranges from $5,000-$12,000 for initial setup, followed by monthly retainers starting at $2,500 for managed optimization and reporting. These figures are estimates and will be refined after an account audit.
To see how this fits into long-term growth systems, review our high-level services and capabilities on the Services Overview and our agency approach on the About Prebo Digital. These links explain how portfolio bidding integrates with CRO, server-side tagging, and revenue-focused analytics.
Once a quote is accepted we begin with a prioritized implementation roadmap: map conversions to primary revenue streams, configure portfolio bid strategies (Target ROAS, Maximize Conversion Value with target ROAS, or Target CPA where appropriate), and instrument server-side tracking to reduce attribution leakage. For Shopify and Stripe flows we recommend aligning ecommerce revenue events to a single source of truth to measure MER and LTV-driven bidding decisions.
A typical engagement timeline for portfolio bid strategy consulting is 6-12 weeks for strategy and initial implementation, then ongoing monthly optimization. Milestones include discovery (week 1), architecture and tracking (weeks 2-3), bid strategy rollout (weeks 4-6), and test & ramp (weeks 7-12). Monthly retainers support iterative testing, audience refinement, and cross-channel attribution reconciliation.
A US ecommerce brand spending $120,000/month across search and shopping may see a modeled CAC improvement of 10-25% after aligning portfolio ROAS targets with gross margins and LTV forecasts. These are illustrative ranges based on Prebo Digital's experience and depend on data quality and seasonality. We always exclude weak-converting segments before scaling to protect margins.
Accurate portfolio bidding requires clean data pipelines. We integrate GA4, server-side tagging, and conversion modeling to reconcile platform-reported metrics with backend revenue. Adhere to US privacy rules and CCPA considerations when using first- and third-party signals; our tracking plans include consent-aware server-side configurations.
Note: portfolio bid strategies perform best when conversion windows, offline conversions, and revenue mapping are consistent across campaigns. Estimates for CAC or ROAS improvements depend on historical data and are provided after the discovery audit.
