CSS · Price comparison · AI visibility

Google Shopping via CSS
Same click, up to ~20% cheaper
As a CSS (Comparison Shopping Services) partner, we list your products in Google Shopping through our infrastructure — not through the standard Google account. The CSS programme mechanism reduces the real cost of the click, and the difference stays with you.
- ✓Your products appear in Shopping without the standard auction markup
- ✓You keep full control: you choose which products and what budget to promote
- ✓Migration from your Merchant Center account with no loss of performance history
- ✓Transparent reporting — you see exactly what you pay and what you get
Up to ~20% savings per click, through the official CSS mechanism


Price comparison with a semantic engine
Same product, all prices. No duplicates.
Our comparison engine does not match products by title. Our own semantic engine understands what the product is and links it based on EAN/GTIN codes — so the same product from 5 stores appears once, with all 5 prices side by side.
- ✓Over 2.8 million products indexed and updated daily
- ✓EAN/GTIN matching + semantic matching for products without a code
- ✓Similar offers generated by the vector engine, not manual rules
- ✓Traffic from the comparison engine goes straight to your product page
Visibility in AI search
When the customer asks the AI, the answer should be your product
More and more buyers no longer search on Google — they ask ChatGPT, Gemini or Perplexity. We optimize your catalog structure (structured data, clean feeds, machine-readable content) so AI assistants find you and recommend you.
- ✓Structured data and feeds prepared for consumption by AI agents
- ✓Indexable, fast product pages with correct price and availability
- ✓We monitor how you appear in AI answers and continuously adjust

What we actually do
The complete infrastructure of your catalog
We don't sell promises. We operate feeds, Merchant Center accounts and data pipelines daily — exactly what you see below.
Feed management
We clean, complete and validate your product feed: titles, attributes, GTINs, Google categories. The feed is the foundation — everything else depends on it.
Google Merchant Center
We set up and manage Merchant Center accounts, including multi-account architectures. We resolve suspensions, warnings and feed errors.
Price comparison
We list your products in our comparison engine, with prices updated daily and traffic sent straight to your product pages.
CSS campaigns
We move your Shopping campaigns to our CSS, with up to ~20% savings per click and the same visibility in Google.
AI visibility (GEO)
We prepare your catalog for the era of conversational search: AI assistants read, understand and recommend your products.
Marketplace Sync
Add-on for syncing your catalog with marketplaces: stock and prices aligned automatically across all channels.
