Frequently Asked Questions
Should I Block IonCrawl?
Decide who benefits. IonCrawl collects pricing, product, and brand data for its operator's clients, and those clients can include your competitors. Allow it if visibility in market research matters to you. Block it if you would rather not hand competitors structured data about your business. Almost none of the top websites we track have robots.txt rules for IonCrawl right now.
Does IonCrawl Follow Robots.txt Rules?
Yes. IonCrawl is expected to follow robots.txt rules, so a disallow rule is the right first move. Automatic Robots.txt adds and maintains that rule for you, and Agent Analytics confirms IonCrawl actually follows it.
Does IonCrawl Access Private Content?
Public business information is the target. Pricing pages, product listings, and announcements are what its clients pay for. IonCrawl has no special access, but assume everything you publish openly gets collected.
Why Is IonCrawl Visiting My Website?
A client of IONOS is monitoring your market, your brand, or you specifically. Expect IonCrawl's visits to concentrate on pages with business value, like pricing and product pages.
How Can I Tell if IonCrawl Is Visiting My Website?
Agent Analytics tracks IonCrawl visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user agent string contains "IonCrawl". Look for repeated visits to pricing, product, and news pages. Keep in mind that IonCrawl doesn't publish a verification method, so any client can claim its user agent string and a log match is a hint rather than proof.
