    First-Party Data

    Your data is now your competitive advantage.

    As third-party signals disappear, the brands that win are the ones feeding their own commercial data back into Google's algorithms. Transaction history, customer value, real margins - this is the data that separates profitable bidding from guesswork.

    We help brands build first-party data infrastructure that makes Smart Bidding commercially intelligent.

    Your Data Assets

    Four data sources Google doesn't have access to

    You already own the most valuable bidding signals. The challenge is structuring them so Google can actually use them.

    Transaction Data

    Order values, product margins, return rates, repeat purchase behaviour - the commercial signals that Google never sees but should inform every bid.

    How we use it: Offline conversion import with profit-adjusted values. Smart Bidding learns what a genuinely profitable conversion looks like.

    Customer Lists

    Your existing customer base is your most valuable targeting asset. Segmented by LTV, purchase frequency, and product category - not just 'all customers.'

    How we use it: Customer Match audiences for acquisition lookalikes, suppression of low-LTV repeaters, and bid adjustment by customer value tier.

    Email & CRM Signals

    Email engagement, browsing behaviour, abandoned carts, and subscription status. These signals predict purchase intent better than any third-party cookie.

    How we use it: Enhanced conversions matching, CRM-informed bidding adjustments, and audience segmentation for campaign structure.

    Product & Inventory Data

    Real-time stock levels, margin by SKU, seasonal demand curves, and supplier lead times. This data determines which products deserve ad spend today.

    How we use it: Feed-level bid modifiers, dynamic budget allocation by margin tier, and stock-aware campaign management.

    Common questions about first-party data

    As third-party cookies disappear and browser restrictions tighten, Google's Smart Bidding algorithms have less data to work with. First-party data - your own customer and transaction data - fills that gap. Brands that feed their commercial data back to Google maintain bidding accuracy. Those that don't are letting the algorithm guess.

    Transaction data (order values, margins, returns), customer identifiers (hashed emails, phone numbers), CRM segments (LTV tiers, purchase frequency), and product data (stock levels, margins). The key is structuring this data so it's actionable for bidding, not just interesting for reporting.

    Customer Match lets you upload hashed customer lists to Google, which matches them to logged-in Google users. This enables suppression (stop advertising to existing customers), lookalike targeting (find similar high-value prospects), and bid adjustments by customer tier. For brands with 10k+ email addresses, the match rates typically justify the setup investment within weeks.

    Yes, through offline conversion import. You capture the GCLID (Google Click ID) at the point of conversion, then import back the actual commercial outcome - profit after COGS, returns, and fulfilment costs. This shifts Smart Bidding from optimising for revenue to optimising for real profit.

    Foundation work (enhanced conversions, GCLID capture) shows impact within 2-4 weeks as Smart Bidding receives better signals. Full profit-adjusted bidding typically takes 8-12 weeks to mature, as the algorithm needs sufficient conversion volume to learn the new value signals. The compounding effect means performance improvement accelerates over time.
