Product Feed Management for Omnichannel Advertising

Consider Wethenew, the fast-growing streetwear resale platform. Prior to partnering with Lengow, they relied on a basic Shopify app to feed Google Merchant Center, resulting in slow syncs and poor data customization. NetAmplify allowed a 4‑person team to manage 40,000 active product variants, greatly improve feed freshness (syncs up to once‑hourly), and extend into four new European markets with custom, channel‑specific feeds. The outcome: a 30 % increase in Google Ads ROAS and healthier campaign scalability across Meta, and affiliate platforms

Maisons du Monde, a home & garden leader with over 180,000 products, wanted to automate feed distribution to social channels like Facebook, Instagram, Pinterest, TikTok, and Snapchat. Using NetAmplify, they now distribute from a single unified catalogue, segmented with custom labels and exclusion rules to isolate marketplace-sold products and manage stock-driven campaign targeting. Since implementing the solution, they halved their time-to-market and achieved high dynamic publishing across four countries with minimal manpower

When feeds are complete, channel-ready, and dynamically synced, ad performance improves significantly. Wethenew's hourly feed refreshes and use of Custom Labels enabled advanced segmentation in Performance Max campaigns (ensuring relevance based on promotions, margins, and inventory) with measurable impact: 30 % ROAS boost and easier entry into new channels. Meanwhile, Maisons du Monde achieved agile social commerce performance, automating product exclusions (e.g. out-of-stock or third-party listings), tailoring feed content per platform, and reducing manual campaign prep time by 50 %, delivering richer, faster campaigns across 180,000 SKUs with consistency and control
