Through incremental prediction models, Criteo can target high-value users, exclude recent converters, and optimize dynamic creatives based on real user intent and product data. Unlike Meta or TikTok, Criteo combines **audience signals** with **product feed optimization**. This means that user segments from Innkeepr (e.g. high-value shoppers, churn risks) are matched with your live merchant feed to deliver relevant product ads across web and app inventory. *** ## Prerequisites **Technical Requirements:** * Active **Criteo Advertiser Account** * Active **Product Feed** (XML, CSV, or Merchant Center sync) * **Criteo OneTag** installed on your website (or Events API) * Innkeepr integration connected to your Criteo account *** ## Use Cases Innkeepr supports four primary use cases for **Criteo audience signals**: ### 1. Seed Audiences – Prospecting Use high-quality seed segments (e.g. top 30% predicted converters) to power Criteo’s **Similar Audience** expansion. Best for: Cold acquisition campaigns that target new users similar to your best customers. ### 2. Retargeting Audiences – Re-engagement Retarget users who viewed products or started checkout but didn’t complete a purchase. Innkeepr ensures only users with incremental conversion potential are included. Best for: Dynamic retargeting ads that feature recently viewed or abandoned products. ### 3. Exclusion Audiences – Spend Protection Exclude users who recently purchased or are predicted to have low incremental impact. Best for: Preventing ad waste on converted or inactive users. ### 4. Value-Based Audiences – CLV Segmentation Create segments based on lifetime value (LTV), purchase frequency, or subscription tier. Best for: Tiered campaigns that prioritize premium or high-value customers. *** ## Setup Instructions ### Step 1: Connect Criteo to Innkeepr 1. In **Innkeepr**, navigate to **Connections → Browse** 2. Click **Connect Criteo** 3. Sign in with your Criteo Advertiser credentials 4. Grant Innkeepr permissions to: * Upload audience lists * Send event data (view, add\_to\_cart, purchase) * Access merchant feed attributes 5. Confirm the connection — Criteo will now appear as an active destination *** ### Step 2: Create Audiences in Innkeepr 1. In **Innkeepr → Audiences**, click **Create Audience** 2. Choose **Criteo** as your destination 3. Set **Audience Type** to: * *Seed* for prospecting * *Retargeting* for re-engagement * *Exclusion* to remove users from campaigns 4. Define segmentation rules (e.g. 30-day lookback, top 50% incremental score) 5. Set your campaign **objective** (e.g. conversion, retention) 6. Click **Create** — your audience will sync to Criteo within 24–48 hours *** ## Monitor & Optimize Test Innkeepr audiences against your existing Criteo setup before rolling them out broadly. Keep creatives, bidding, and budget identical between control and test so performance differences are attributable to the Innkeepr audience. **Weeks 1–2: Observation Phase** * Do **not** adjust budgets, bids, or creatives during the initial learning phase * Confirm both the control and test campaigns are spending their allocated budget * Verify that conversions are being tracked correctly **Weeks 2–4: Evaluation** * Compare **ROAS, new customer share, and AOV** between the control and test campaigns * For exclusion audiences, watch that reduced reach does not cut conversion volume without improving efficiency * For seed and retargeting audiences, check whether the Innkeepr segment outperforms your standard Criteo audiences **After Week 4: Rollout** * Roll the best-performing audiences out to your other active Criteo campaigns * Scale budget on winning audiences incrementally (20–30% per increase) and allow 3–5 days to stabilize before evaluating again * Refresh audiences periodically so predictions stay current *** ## Best Practices * **Segmentation depth:** Keep audiences large enough for delivery (1,000+ users recommended) * **Creative isolation:** Test one variable at a time — if you add or change creatives, do so across control and test simultaneously * **Dynamic creatives:** Enable Criteo's Dynamic Ads format so audience segments are paired with personalized product recommendations * **Value tiers:** Use Innkeepr's LTV scoring to run tiered bid strategies (e.g. Gold, Silver, Bronze) * **Feed hygiene:** Keep your product feed refreshed and free of expired or unavailable products so ads render correctly * **Combine audience types:** Seed, retargeting, and exclusion audiences are complementary — apply exclusions to prospecting and retargeting campaigns once each audience has been validated individually *** ## Troubleshooting ### Audience Not Populating **Issue:** Audiences don’t appear in Criteo **Solutions:** * Confirm Criteo is connected as a destination in Innkeepr * Ensure your OneTag or API events are firing (`view_item`, `add_to_cart`, `purchase`) * Check minimum audience size (1,000 users recommended) * Wait 24–48 hours for sync *** ### Feed Sync Failed **Issue:** Product feed not updating or missing items **Solutions:** * Verify your feed URL or upload schedule in Criteo Merchant Center * Ensure feed attributes match required fields (ID, price, URL) * Check that product IDs align with event IDs in Innkeepr *** ### Low Match Rate **Issue:** Audience size in Criteo much smaller than in Innkeepr **Solutions:** * Confirm emails or hashed identifiers are included in Innkeepr audiences * Check for missing product IDs in event payloads * Allow 24–48 hours for data matching to complete *** ### Purchase Events Missing **Issue:** Criteo doesn’t receive purchase data **Solutions:** * Verify `purchase` events are firing correctly on the confirmation page * Confirm your Criteo pixel or API is active and authorized * Review Innkeepr → Events for incoming purchase events * Contact Innkeepr support if issue persists *** ## Related Articles * [Set Up Seed Audiences on TikTok](/guides/how-to-guides/tiktok-seeds) * [Set Up Seed Audiences on Meta](/guides/how-to-guides/meta-seeds) * [Set Up Audience Signals on Performance Max](/guides/how-to-guides/pmax-audiences) * [Conversion Signals](/guides/signals-and-activation/conversion-signals) * [Spec: Identify](/connections/spec-identify)
