Why Is IBM-Watson-NLU Visiting My Website?
Someone shared a link to your page. IBM-Watson-NLU fetched it to build a preview card, and each new share may trigger another request. A spike often means your content is circulating more widely.

Frequently Asked Questions
What Traffic Patterns Should I Expect From IBM-Watson-NLU?
IBM-Watson-NLU usually makes a single request within seconds of a URL being shared, without crawling further. Traffic rises and falls with sharing activity, so a widely circulated link can produce a sharp burst of fetches.
Does IBM-Watson-NLU Follow Robots.txt Rules?
No. IBM-Watson-NLU is not expected to follow robots.txt rules, so a disallow rule only communicates your preference. Use Bad Bot Blocking to reject its requests, then use Agent Analytics to verify that they stop.
Is IBM-Watson-NLU Used for AI Model Training?
Not ordinarily. IBM-Watson-NLU is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking IBM-Watson-NLU Affect AI Search or Citations?
Not directly. IBM-Watson-NLU's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does IBM-Watson-NLU Access Private Content?
No. IBM-Watson-NLU has no credentials and should access only the public URL and assets needed for a preview. It does not continue through the rest of your site.
How Can I Verify a Request From IBM-Watson-NLU?
Agent Analytics tracks IBM-Watson-NLU visits in real time. You can also check your server logs for requests whose user-agent string contains "IBM-Watson-NLU". Look for a page and its preview assets being requested without follow-up navigation. Because IBM-Watson-NLU does not publish a verification method, any client can claim its identity and a log match is only a clue.
