TL;DR: What Simprosys Does
- ✅ Fast Sync: According to the developer, price and stock changes reach Google within 30 minutes.
- ✅ Historical Data Protection: Flexible ID mapping ensures your Performance Max (PMAX) campaigns don’t lose their “learning” history.
- ✅ Global Scaling: Seamless integration with Shopify Markets for multi-currency and multi-language feeds.
- ✅ Tracking: Supports Google Consent Mode V2 and GA4. Note: no direct TikTok feed, and the developer is based in India.
Most Shopify merchants start their journey with the free “Google & YouTube” app. It works for a while, but as soon as your catalog grows or you plan to expand internationally, you hit a wall. Inflexible data structures, cryptic Merchant Center errors, and “Price Mismatch” disapprovals become daily headaches that eat into your profit margins.
Simprosys Google Shopping Feed is the tool that steps in where the standard solution fails. It transforms your raw Shopify data into high-performance marketing assets. If you’ve ever struggled with Google rejecting products due to “missing GTINs” or “incorrect color attributes,” this app is worth a look.

How the Sync Works
Simprosys sends your product data to Google Merchant Center through an API connection instead of providing an XML or CSV file that Google fetches at fixed intervals. According to the developer, changes reach Google within 30 minutes. That matters because mismatched prices between feed and shop can lead to disapprovals in Merchant Center.
Important for 2026: Google deprecated the Content API for Shopping on August 18, 2026. Its successor is the Merchant API, and the old API will be switched off in early 2027. Whether Simprosys has already migrated is not stated in the developer’s public documentation (as of October 22, 2026). Ask support before you buy.
Mastering ID Mapping: Don’t Kill Your ROAS
One of the most critical mistakes when switching feed tools is changing product IDs. Google’s algorithms—especially Performance Max—use the product ID as the anchor for all historical performance data. If this ID changes, Google “forgets” everything it learned about that product, forcing your campaigns back into a learning phase. The result? A massive drop in your Return on Ad Spend (ROAS).
Simprosys offers four ID formats (Global, SKU, Variant ID, and Product ID & Variant ID). During setup, you choose the format that matches your previous app. This ensures your top-sellers remain recognized by Google, allowing your campaigns to continue running smoothly without a hitch.
Feed Optimization: Better Data for Google
In Google Shopping auctions, the winner isn’t always the one with the highest bid; it’s the one with the highest relevance. Your product data is the “currency” you pay with. Simprosys allows you to optimize titles and descriptions specifically for the Google feed without changing the customer-facing design of your Shopify store.
Better titles help Google match your products to the right searches. With Simprosys, you can use automated Bulk Edit rules to move high-intent keywords, brands, or technical specs to the front of the title. This is crucial in categories like electronics or fashion, where users search for very specific attributes.
🔥 Expert Tip: Never ignore GTINs (EANs). Google uses these identifiers to match your products exactly with manufacturer data. Simprosys identifies products with invalid barcodes instantly, letting you fix them via CSV import.
Video Guide: Setting Up Your Feed for Success
The dashboard shows which products Google rejected and why. This video by Ecom Chris walks through the first setup steps:
Global Scaling with Shopify Markets
International expansion is the biggest lever for growth. However, Google will reject products if the currency in the feed doesn’t perfectly match the landing page. Simprosys offers seamless integration with Shopify Markets. It automatically recognizes your market configurations and generates specific feeds for each region—whether it’s USD for the States, GBP for the UK, or EUR for Germany—synced with your shop’s localized subfolders. Three Markets feeds are included; each additional one costs 10% of the base price.
Tracking and Data Protection
Simprosys uses the Shopify Web Pixels API to track conversions. It automates the setup for GA4 and Google Ads Conversion Tracking, including vital events like “Add to Cart” and “Begin Checkout.”
Crucially for EU merchants, the Shopify app natively supports Google Consent Mode V2. Tracking follows your visitors’ consent. If someone declines, Google can model conversions through Consent Mode; that is a Google feature, not part of the app.
On data protection: Simprosys is based in Ahmedabad, India. The developer does not publish a data processing agreement, server location or list of subprocessors, and its terms are governed by Indian law. The EU has no adequacy decision for India. Interface and support are available in English only. A plus for German shops: the unit pricing attributes for Google (unit_pricing_measure and unit_pricing_base_measure) are supported.
💡 Pro-Tip: The “Zombie SKU” campaign is a separate Performance Max campaign meant to revive weak products from an existing PMax campaign. Requirement: the original campaign was created through the app at least 30 days earlier.
Comparison: Simprosys vs. Native App vs. Enterprise Tools
| Feature | Native Google App | Simprosys | DataFeedWatch |
|---|---|---|---|
| Pricing | Free | From $4.99/mo | From €54/mo (1,000 products) |
| Control | Minimal | High (Bulk Rules) | Maximum (Complex Logic) |
| Support | Basic | Live chat and email (English only) | Agency-focused |
Pricing: Low Entry, with Add-ons
Simprosys charges by the number of products, and variants (sizes, colors) don’t count extra. The smallest plan costs $4.99 per month for up to 500 products; up to 5,000 products it is $13.99 (as of October 22, 2026). Billing counts all products published in Shopify, including those you don’t send to Google.
Add-ons cost extra: the XML feed (+35%), each Markets feed from the fourth (+10% each), and AI optimization (one-time $1 per 25 products). Annual billing saves 10%.
Compared with tools like DataFeedWatch, Simprosys is cheap. Shopify’s Google & YouTube app costs nothing, though, and is often enough for simple catalogs.
Final Verdict: The Foundation for Scaling
If you want to run Google Shopping as a real revenue channel, you need control over your product data. Simprosys is a solid choice for that: the direct connection, feed rules and Markets feeds speak for it. Deductions go to the missing German interface, the company’s base in India without a published data processing agreement, and the lack of a TikTok feed.
