Audit existing traffic and conversion data to identify drop-off points in the funnel. 2. Define retargeting audience segments based on behavior, intent level, and recency. 3. Map retargeting touchpoints: which platform, which message, at what frequency. 4. Build sequential messaging strategy: progressive engagement based on journey stage. 5. Create dynamic product/personalized ad creative for each audience segment. 6. Configure audience exclusions to avoid wasted spend and ad fatigue. 7. Set frequency caps and budget allocation across platforms. 8. Launch campaigns with conversion tracking and attribution modeling. 9. Monitor daily: frequency, CPA, ROAS, and creative fatigue indicators. 10. Iterate weekly: refresh creative, optimize audiences, adjust bids. ## Audience Segmentation ### Retargeting Audience Architecture ``` RETARGETING AUDIENCE SEGMENTS =============================== INTENT-BASED SEGMENTS: HIGH INTENT (Bottom of Funnel): → Cart abandoners: Added to cart but didn't check out Window: 1–7 days (highest conversion) Creative: Product-specific, urgency, social proof Expected CVR: 5–15% Budget: 30–40% of retargeting total → Checkout abandoners: Started checkout but didn't complete Window: 1–3 days (very high urgency) Creative: "Complete your purchase" + free shipping / guarantee Expected CVR: 8–20% Budget: 20–25% of retargeting total → Price page visitors: Viewed pricing or plans page Window: 1–14 days Creative: Value proposition, comparison, testimonials Expected CVR: 2–8% Budget: 15–20% of retargeting total → Demo/trial requesters: Filled form but didn't convert Window: 1–14 days Creative: "Still exploring?" + social proof + CTA Expected CVR: 10–25% Budget: 15–20% of retargeting total MEDIUM INTENT (Middle of Funnel): → Product page visitors: Viewed specific product pages Window: 1–30 days Creative: Product benefits, features, comparison Expected CVR: 1–5% Budget: 15–20% of retargeting total → Blog/content readers: Consumed educational content Window: 7–60 days Creative: Next-step content, case studies, webinars Expected CVR: 0.5–3% Budget: 10–15% of retargeting total → Video viewers: Watched 50%+ of product/explainer video Window: 7–30 days Creative: Continue the narrative, deeper content Expected CVR: 1–4% Budget: 10–15% of retargeting total LOW INTENT (Top of Funnel): → Homepage visitors: Viewed only homepage Window: 14–90 days Creative: Brand awareness, value proposition Expected CVR: 0.2–1% Budget: 5–10% of retargeting total → Social engagers: Liked, commented, shared content Window: 30–180 days Creative: Content upgrade, newsletter signup Expected CVR: 0.5–2% Budget: 5–10% of retargeting total AUDIENCE SIZE REQUIREMENTS: → Google Ads: Minimum 100 active users (last 30 days) → Meta: Minimum 1,000 users (500 for some regions) → LinkedIn: Minimum 100 members (500+ recommended) → Display (DV360): Minimum 1,000 users EXCLUSION LAYERS (Critical): → Past purchasers (last 180 days): Exclude from product retargeting → Current trial users: Exclude from free trial retargeting → Internal IPs: Exclude employees → High-frequency viewers: Exclude users at frequency cap → Converted users: Exclude from same-funnel retargeting ``` ##
