Inspiration – Test whether a post‑add cross‑sell slide‑in increases attach rate and AOV

Overview

Goal: Boost AOV by suggesting 1–2 relevant add‑ons immediately after an item is added to cart.

Build time: 6–8 minutes.

Expected impact: 8–18% lift in attach rate; 4–12% AOV increase.

Hypothesis

Showing a timely, highly relevant cross‑sell right after add‑to‑cart leverages shopping momentum. A lightweight slide‑in with one‑click add reduces friction and improves attach rate without derailing the checkout flow.

Assumptions

• Timing: Post‑add moments have high purchase intent and receptivity to complements.
• Relevance: Curated, context‑aware add‑ons outperform generic “related items.”
• Cognitive Load: Limit to 1–2 choices to avoid decision fatigue.
• UX Continuity: Slide‑ins preserve context better than full modals or page redirects.

Setting up the experiment in Personizely (Widget)

Run a widget test with:

• Control: No post‑add cross‑sell (or legacy confirmation).
• Variant: Slide‑in cross‑sell offering 1–2 add‑ons with one‑click add.

Use clear labels (e.g., “Frequently added with this”), show price and total impact, and include a small “No thanks” link. Cap to 1 impression per session.

Recommended configuration:

• Trigger: Fires on Add to Cart event for selected SKUs.
• Targeting: Exclude carts with ≥3 items; prioritize high‑margin/compatible add‑ons.
• Goals: Purchase
• Layout: Vertical slide‑in with image, title, price, and 1‑click add button.
• Frequency cap: 1 per session; suppress after converting or dismissal.

Additional notes:

• Keep choices ≤2; preselect quantity = 1.
• Avoid discounts initially to measure pure merchandising impact.
• Ensure images are consistent and text wraps cleanly on mobile.
• Respect inventory and prevent adding duplicates if already in cart.

This widget test will reveal whether a post‑add slide‑in cross‑sell improves attach rate and AOV without harming progression to checkout.
