Writing one policy for Dassault Systemes (Netvibes)
A robots.txt file cannot say "Dassault Systemes (Netvibes)"; it can only name Dassault Systemes (Netvibes)'s tokens, one group at a time. With a single token, one group is the whole policy.
# One token controls everything Dassault Systemes (Netvibes) fetches through it
User-agent: Netvibes
Disallow: /private/
Allow: /- Decide per job, not per company. Training, search and user-triggered fetching have different trade-offs, even from the same operator.
- Name every token you mean. A token you leave out follows
User-agent: *. - Repeat shared rules. A named group ignores the
*group, so copy anyDisallowlines you still want it to obey. - Verify from outside. Run the crawlability checker for AI search after any change to see the result for each Dassault Systemes (Netvibes) token, including firewall refusals.
Test yourself: does User-agent: Dassault Systemes (Netvibes) block all of Dassault Systemes (Netvibes)'s crawlers?
No. robots.txt matches crawler tokens, not company names. Use the token Netvibes.
Test yourself: if you block one Dassault Systemes (Netvibes) token, are the others blocked too?
No. Each token is read separately. Blocking one leaves the rest following whatever group applies to them.

Common mistakes with Dassault Systemes (Netvibes)'s crawlers
