Idealo is a bot in the content aggregators category, operated by Idealo internet GmbH.
Germany's largest price comparison service. Runs four crawler variants (pricevalidator, badgechecker, inventoryanalyser, inventory-image-downloader) to verify partner shop prices, check badge integration, analyse inventory, and download product images.
Aggregators collect articles and links from many sites to build news feeds, read later apps and discovery services. Some send referral traffic, others republish your content. Check what each one does with your pages before allowing it.
Sample user agent strings sent by Idealo:
Mozilla/5.0 (compatible; idealo-bot pricevalidator; https://partner.idealo.com/de/bot/)Mozilla/5.0 (compatible; idealo-bot badgechecker; https://partner.idealo.com/de/bot/)Mozilla/5.0 (compatible; idealo-bot inventoryanalyser; https://partner.idealo.com/de/bot)Mozilla/5.0 (compatible; idealo-bot inventory-image-downloader; https://partner.idealo.com/de/bot)Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.
Idealo follows robots.txt, so these rules stop it crawling the paths you choose. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.
User-agent: idealo-bot Disallow: /
User-agent: idealo-bot Disallow: /private/ Disallow: /search
User-agent: idealo-bot Allow: /blog/ Disallow: /
User-agent: idealo-bot Allow: / User-agent: * Disallow: /
User-agent: idealo-bot group, Idealo ignores your User-agent: * rules, so repeat any that should still apply.idealo-bot from Idealo's user agent; check Idealo internet GmbH's own documentation if it publishes a different robots.txt name.Treat robots.txt as a statement of your policy, and enforce it where requests arrive.
Idealo fetches pages when your links are shared or syndicated. Keep it allowed so previews and feeds work, but leave it out of page views and ad requests.
Transfon Security for publishersWhen ads or posts are shared, Idealo fetches the landing page. Those hits are not clicks, so keep them out of campaign reports.
Transfon Security for advertisersProduct links shared in chats and feeds are fetched by Idealo. Keep it allowed so previews show the right image and price.
Transfon Security for e-commerceAllow Idealo on public pages so shared links preview well, and keep it off the app.
Transfon Security for SaaS and APIsrobots.txt is a request, not an enforcement. Transfon Security shows Idealo by name in the Top Bots report, so you can see how often it visits and which pages it reads. Block or allow it with a User Agent rule, or slow it down with a rate limit decision rule.

Yes. Idealo follows robots.txt, so a Disallow rule for the idealo-bot user agent stops it from crawling the paths you list.
Add "User-agent: idealo-bot" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "idealo-bot" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so Idealo may not follow it, and anyone can send Idealo's user agent, so a fake Idealo ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
