Track this bot on your siteWhat is NovaAct?
Nova Act is Amazon's AI agent that can use a web browser to navigate websites and complete multi-step tasks on behalf of a human user.
What NovaAct means for your site
NovaAct is an autonomous AI agent that browses the web using a real browser, operated by Amazon. Unlike traditional crawlers, it can interact with your pages like a human, navigating links, reading content, and completing multi-step tasks. This is a new and rapidly evolving category of web visitors.
What should you do?
- Monitor activity patterns to understand what the agent does on your site
- Review which pages the agent visits most frequently
- Control access via robots.txt if needed
- Keep an eye on form submissions or interactive behavior

BotSights tracks every NovaAct visit in real time, including which pages it crawls, how often, and from where.
How to identify NovaAct
NovaAct uses the user-agent "novaact" and respects robots.txt. AI browser agents may behave more like humans than traditional bots.
novaactNovaActHow to block NovaAct
Three robots.txt options below. Pick the one that matches your goal. Each snippet lists every known NovaAct user-agent pattern so the rules apply regardless of which one the bot announces.
Edit robots.txt with care
A single misplaced line can de-index your entire site. Common mistake: pasting User-agent: * followed by Disallow: / blocks every bot, not just NovaAct, including Googlebot. Always paste the snippet between existing rules (not over them), keep the User-agent line scoped to NovaAct's patterns, and verify with Google's robots.txt tester before deploying. If you are not sure, ask a developer first.
Option 1: Block all access
Tells NovaAct not to crawl any URL on your site. Use this when you want the bot completely off your content.
User-agent: novaact
User-agent: NovaAct
Disallow: /Option 2: Block specific paths only
Keep public content crawlable but exclude sensitive or non-public sections. Add one Disallow: line per path. Replace the example paths with your own.
User-agent: novaact
User-agent: NovaAct
Disallow: /admin/
Disallow: /private/
Disallow: /checkout/Option 3: Slow down with a crawl delay
Crawl-delay is a voluntary directive that asks the bot to wait the given number of seconds between requests. Useful when NovaAct is hammering your origin and slowing the site down for real visitors, but you do not want to block it outright. The value is in seconds, so 10 means at most one request every ten seconds. Not all bots honour this directive (Googlebot ignores it; Bingbot, Yandex, and many AI crawlers do respect it).

What is the User-Agent for NovaAct?
NovaAct identifies itself with the User-Agent string "novaact" (alternate forms: NovaAct). AI browser agents may use a real browser engine (Chromium-based), so the UA can look human at first glance — check for the operator-specific marker.
Is NovaAct a real user?
No. NovaAct is an AI agent acting on behalf of a human user. It browses autonomously using a real browser, often clicking links and reading content like a person would, but the navigation decisions are made by an AI, not the user directly.
Should I treat NovaAct as a human or as a bot?
Technically a bot — count it separately in analytics. But treat it like a high-intent visitor, since each visit represents a real human task being executed on their behalf. NovaAct sessions often correlate with research, comparison, or buying intent.
Will NovaAct fill out forms or trigger conversions?
Possibly. AI browser agents can interact with forms, click buttons, and complete checkouts when instructed. It should respect robots.txt boundaries, but interactive flows are an evolving area.
Should I block NovaAct?
Monitor first. AI browser agents are a new and rapidly evolving category — many provide real user-on-behalf-of value (research, shopping, scheduling). Block only if you see unwanted behavior like form spam, scraping at scale, or terms-of-service violations.
How do I tell NovaAct apart from a real user in analytics?
Server logs show the User-Agent. NovaAct UA is "novaact". BotSights detects this and flags it separately from human visits, so your conversion-rate calculations stay clean.
