8x ROAS on Black Friday; Spring Sale targeting 10x on a rebuilt, AI-powered platform.

Veinlite had a problem that looked like a platform problem but was really a visibility problem. After migrating from Magento to Shopify in November 2025, their conversion tracking broke — Google Tag Manager couldn't see into Shopify's sandboxed Web Pixel environment, leaving their Target ROAS campaigns flying blind.

The symptoms: 0 primary conversions tracked for 14+ days. Target ROAS bidding had no signal to optimize against. Campaigns were running on gut feeling, not data.

Compounding the issue: their content velocity was low, their Google Ads structure was dated (still built for keyword management, not AI-powered Performance Max), and their Spring Sale — their most important revenue event of the year — was 6 weeks away.

Conversion Infrastructure First

Before touching a single campaign, we rebuilt the measurement layer. The fix required understanding that Shopify Web Pixels run in an isolated sandbox — invisible to browser-based Tag Manager. We implemented server-side conversion tracking via Shopify's native Google channel integration, confirmed GA4 Realtime data, and validated the Google Ads conversion action (AW-1009276097) was firing correctly on completed purchases.

With real data flowing, we switched the primary campaign from Target ROAS (data-starved) to Maximize Conversion Value, and imported the GA4 purchase event as a secondary conversion signal for reinforcement.

Campaign Restructure for AI Bidding

Google Ads in 2026 runs on AI, not keywords. The "Q2 2025 Shopping" campaign at $150/day was rebuilt around Performance Max principles — better asset groups, stronger product feed, conversion value rules by product line. The "Vein Finders" search campaign (PAUSED) was scoped for relaunch with updated broad match + smart bidding.

AI Content Pipeline

We deployed an AI content engine that researches clinical topics, drafts SEO-optimized posts, and queues them for human review. Output went from 1-2 posts/month to weekly cadence — covering the clinical audience pillars (pediatric IV access, oncology, home health nursing, GPO procurement) that drive Veinlite's institutional sales cycle.

Spring Sale Infrastructure

The Spring Sale (March 13–15, 2026) was scoped as a full-funnel campaign: countdown timer emails via Klaviyo, updated ad copy with urgency messaging, ad budget surge plan, and ROAS target of 10x — benchmarked against the 8x achieved on Black Friday 2025.
