World Inspire Product Feed for Google Shopping

World Inspire Product Feed for Google Shopping and Trustmate generates real-time, compliant XML feeds for Google Merchant Center (Google Shopping, Free Product Listings) and Trustmate customer review sync.

Engineered with an Anti-Cache Streaming Architecture, this plugin completely bypasses reverse-proxy static disk cache traps (Varnish, SiteGround, Cloudflare, Hostinger), delivering fresh, accurate inventory, pricing, and multi-country shipping data directly from your WordPress database.

🌟 Key Features

• Multi-Engine eCommerce Compatibility: Native auto-detection and data extraction for both SureCart (sc_product) and WooCommerce (product). Zero fatal errors if either or neither is active.
• Google Merchant Center Specification: Built according to official Google RSS 2.0 standards with all essential namespace attributes: <g:id>, <g:title>, <g:description>, <g:link>, <g:image_link>, <g:availability>, <g:price>, <g:brand>, <g:condition>, <g:identifier_exists>, <g:google_product_category>, <g:color>, <g:age_group>, and <g:gender>.
• Custom Labels 0–4 for Google Ads / PMax: Full support for <g:custom_label_0> through <g:custom_label_4> with rules for price tiers (< $25, $25-$50, $50-$100, $100+), inventory status, category mapping, clearance/promotion tag keywords, and custom post meta fields.
• Variant Grouping (<g:item_group_id>): Automatically expands WooCommerce variable products (product_variation) into individual variant items linked by parent <g:item_group_id>, enabling swatch selection in Google Shopping results.
• Variant Attribute Optimization: Smart extraction for <g:size>, <g:material> (Gold, Silver, Leather, Cotton, Gemstones, etc.), and <g:pattern> (Solid, Striped, Floral, Beaded) directly from attributes or intelligent NLP heuristics.
• Multi-Country Shipping Generator: Automatically embeds multi-destination <g:shipping> nodes (defaulting to 8 core global markets: US, CA, UK, JP, SG, HK, AE, MX with custom shipping service names and rates).
• Live Diagnostics & Product Inspector Simulator: Test and audit any product ID directly in WordPress Admin to verify extracted attributes, custom labels matching reasons, and preview raw <item> XML snippets.
• Automatic Pet Category Mapping: Heuristically detects pet collars, harnesses, and animal accessories and maps them to Animals & Pet Supplies > Pet Supplies > Pet Collars & Harnesses.
• Trustmate Review Catalog Sync: Dedicated <products> XML feed format ready for instant connection in your Trustmate merchant dashboard.
• Anti-Cache Streaming Engine: Sends strict nocache_headers(), exact Content-Length headers, and memory buffering to guarantee instant updates on Google Merchant Center Scheduled Fetches.
• Zero Bloat & Zero Third-Party Dependencies: 100% native WordPress code, lightweight, fast, and secure.
