What is NovaAct?
Nova Act is an AI agent created by Amazon that can use a web browser. It can intelligently navigate and interact with websites to complete multi-step tasks on behalf of a human user. Agent Analytics can track when it visits your website.

Expected Behavior
NovaAct controls a real browser, so expect it to load pages, run JavaScript, keep cookies, and move through multi step flows the way a person would. Its path through your site follows whatever task it was given rather than a fixed crawl order, so visits look irregular. Sessions can pause on a page while the agent processes content, then jump somewhere unexpected.

Disallow: /Frequently Asked Questions
Should I Block NovaAct?
Usually no. NovaAct browses on behalf of a real person who is trying to read, compare, or buy something on your site. Blocking it turns away that person, not a bot farm, and they will finish the task on a competitor's site instead. Blocking it has no effect on your search rankings. For comparison, 2% of the top websites we track already have robots.txt rules for NovaAct.
Does NovaAct Respect Robots.txt?
No. NovaAct is not expected to honor robots.txt, so a disallow rule only states your preference. Enforce the block with firewall or server rules, then confirm in Agent Analytics that its requests actually stop.
Does NovaAct Access Private Content?
It can if a user gives it access. NovaAct operates a real browser session, so if someone signs in to your site through it, it sees whatever that account sees. Without credentials, it reaches only what any anonymous visitor can reach.
Why Is NovaAct Visiting My Website?
Someone gave NovaAct a task your site can help complete, like researching a product, comparing options, or filling out a form. It reached you through links and search results, the same way a person would.
How Can I Tell if NovaAct Is Visiting My Website?
Agent Analytics tracks NovaAct 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 "NovaAct". Look for sessions that browse like a person but move through pages faster than one. Keep in mind that NovaAct 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.
