What is Tassvi?
Tassvi is an independent price comparison site. For each product you see the current price, delivery cost and delivery time at several shops side by side. Every price belongs to exactly one version of a product, matched by EAN or the manufacturer's part number. When in doubt, we don't match.
On Tassvi you'll find Dog, Cat, Small animals, Birds, Fish and aquariums, Pond, Reptiles, Chickens and Horse.

Who visits?
People in the Netherlands, Belgium, Germany, France, Denmark and Sweden who already have a product in mind and want the best price. They land on a product, brand or category page and click through to a shop to buy. Tassvi is available in each country's language and in English, with prices in the local currency.
Where do visitors come from?
- Search engines: every page is rendered in full on the server, with structured data, hreflang and sitemaps per country.
- AI assistants: ChatGPT, Claude, Perplexity and other assistants read our prices through our public MCP server (https://tassvi.com/mcp) and llms.txt, and point to the product page.
- Social media and the newsletter: plain deal posts, clearly marked as ads.
We share visitor figures on request, from our own cookie-free analytics.
How we link to shops
- Every shop link goes through our own redirect (/out/) and carries rel="sponsored nofollow".
- The footer of every page says that shop links may be affiliate links. The order of prices never depends on commission: https://tassvi.com/nl-en/how-we-rank/
- We show the price, delivery cost and stock from the shop's product feed, per country. A price we haven't seen recently is taken off the site.
- We write our own content: buying guides, top lists and pages per brand and category.
What we don't do
- No cashback, discount codes or voucher site.
- No browser extension or toolbar.
- No search ads on brand names (brand bidding).
- No unsolicited email, no incentivised or bought traffic, no sub-networks.
What we need from a shop
A product feed with, per product, the EAN (or the manufacturer's part number), price, delivery cost, stock and a deep link. A feed per country is welcome: we show each shop only in the countries it delivers to.
