Ciao (ciao.de, ciao.co.uk, formerly also ciao.com) launched in 1999 as a European price-comparison site built around user-submitted product reviews, with members paid small amounts for writing and rating reviews. Its parent, Greenfield Online, was acquired by Microsoft in 2008 for roughly $486 million as part of Microsoft's push into European e-commerce and search. Microsoft later exited the business, and LeGuide Group took over Ciao in 2012. In 2016, Kelkoo acquired LeGuide Group and folded Ciao, LeGuide and Dooyoo alongside its own Kelkoo brand into what is now Kelkoo Group.
The consumer side of Ciao that made it famous did shut down: Ciao announced in November 2017 that it would stop paying members for reviews as of December 1, 2017, and the open review community effectively closed in February 2018. That part is honestly dead. What survives is different: as of the most recent checks, ciao.de and ciao.co.uk still resolve as live pages (Wayback Machine snapshots returned HTTP 200 in September 2025 and February 2026 respectively), and Kelkoo Group's own materials continue to list Ciao as one of its four proprietary shopping-comparison sites. So today's Ciao functions as a merchant price-comparison listing surface inside the Kelkoo Group network, not as the open review site it was in the 2000s and 2010s.
Because a feed submitted to Kelkoo Group's shared merchant system is not limited to one storefront. Ciao, Kelkoo and LeGuide are run as sibling brands under the same corporate umbrella, drawing on the same merchant network and product-data pipeline. In practice, this means a single properly formatted feed can surface across multiple branded comparison sites in several European markets (Ciao's own footprint historically spanned the UK, Germany, France, Spain, Italy, the Netherlands and Sweden) rather than requiring a separate one-off integration purely for Ciao.
That said, prospective advertisers should go in with realistic expectations: Ciao today is a modest, legacy-traffic comparison listing channel riding on Kelkoo Group's infrastructure -- not the high-traffic, review-driven discovery engine it was under Microsoft ownership. Treat it as a low-effort, ride-along channel rather than a primary growth channel.
Third-party integration tooling that lists Ciao as a channel (for example, the Oxatis/Actinic "Ciao" storefront app) describes a two-tier model: a free basic listing that gets a merchant's catalog indexed in Ciao's directory, and a paid "priority listing" tier billed on a pay-per-click basis at a flat, published-rate-card price per click with no signup fee. Paid listings were also described as being distributed onward to partner comparison sites. Separately, feed-tool vendors describe connecting a store to Ciao as also feeding into Kelkoo Group's own KelkooAds distribution and, from there, onward to channels like Google Shopping Ads.
Flag this honestly: this pricing description comes from third-party integrator marketing pages rather than a current, dated Ciao or Kelkoo Group rate card, so treat the CPC mechanic as directionally accurate but confirm current rates directly with Kelkoo Group before budgeting against it.
No standalone, Ciao-branded feed specification was found. What does exist is Kelkoo Group's shared advertiser product-data-feed documentation, which is the system that powers "KelkooGroup shopping campaigns" across its brand sites -- Ciao being one of them. That documentation specifies:
TXT
XML
Because Ciao does not appear to publish its own separate spec today, the safe working assumption -- and the one this page uses -- is that a feed built to Kelkoo Group's product-data spec is what reaches Ciao's listings, rather than there being Ciao-specific field names to hunt down separately.
These attribute names come from Kelkoo Group's shared merchant/product-data feed documentation (the system Ciao listings are inferred to run on), not from a Ciao-only spec page. Kelkoo Group's own guidance confirms some attributes are mandatory across all products, while others are required only for specific product types (its documentation calls out apparel as one example needing extra fields):
id
title
product-url
price
brand
description
image-url
ean
merchant-category
availability
delivery-cost
delivery-time
mpn
Kelkoo Group's documentation is explicit that leaving a required attribute blank or malformed can cause the affected products to be excluded from campaigns entirely, so treat the mandatory five (id, title, product-url, price, brand) as non-negotiable.
Since Ciao's listings run on Kelkoo Group's shared feed infrastructure rather than a Ciao-only portal, Feedance treats this as a Kelkoo Group-schema connection:
Kelkoo Group's documentation states that feeds are fetched on a country-specific schedule, generally three to four times per day -- its own published example for Austria lists fetch times of 00:00, 08:00, 12:00 and 15:00 CET -- and explicitly warns that these timings are "subject to change without prior notice." Since no Ciao-specific schedule is separately published, plan around that same cadence: refresh your feed at least once daily, and ideally in step with a multi-times-per-day rhythm, so price and stock-availability changes don't sit stale between crawler fetches.
No Ciao-specific error codes or error-message text were found in public documentation, so nothing here should be read as a literal error string you'll see in a dashboard. What Kelkoo Group's own guidance does confirm is the underlying failure pattern: if a required attribute is missing or incorrectly formatted, the affected product simply does not show up in listings/campaigns rather than throwing a visible error. In practice, that means the most common issues to check for are:
General, sourcing-independent practices worth applying on any comparison-shopping network, including this one:
Is Ciao still active today? Partly. The open, pay-for-reviews consumer community that made Ciao well known shut down in 2017-2018. But the ciao.de and ciao.co.uk domains still resolve as live pages today and remain listed by Kelkoo Group as one of its shopping-comparison brands, so it still functions as a merchant listing channel.
Is today's Ciao the same business as the Microsoft-owned Ciao from 2008? No. Microsoft owned Ciao's parent company only from 2008; ownership passed to LeGuide Group in 2012 and then to Kelkoo Group in 2016, which still operates it today.
Can shoppers still write or read consumer reviews on Ciao? The paid review/rewards program that defined Ciao ended in December 2017. Today's site functions as a merchant price-listing surface within Kelkoo Group's network rather than an active open review community.
Does Ciao have its own separate feed specification? None was found publicly. Feeds appear to run on Kelkoo Group's shared product-data feed system, which is the same schema this page documents.
Which markets does Ciao cover? Historically Ciao operated sites for the UK, Germany, France, Spain, Italy, the Netherlands and Sweden; current live coverage should be confirmed with Kelkoo Group directly, since not every historical market necessarily still has an active Ciao storefront today.
