Why track Amazon Kendra traffic?
Measure what Amazon gives back. Amazon Kendra takes your content for AI training — but does Amazon send any traffic in return through other products? Track whether the trade-off is worth it before deciding to block.
Understand what content is being collected for AI training. Amazon Kendra crawls your site to gather data that may train AI models. Tracking its activity reveals which pages are selected — and which are skipped.
Make an informed block-or-allow decision. Blocking Amazon Kendra prevents your content from being used in future model training. But first, measure the volume: how many pages does it fetch, how often, and does Amazon send any referral traffic through other products?
Detect content harvesting patterns. If Amazon Kendra is systematically crawling your highest-value content (product pages, proprietary research, premium articles), you may want to restrict access using robots.txt or server-side rules.
What does Amazon Kendra crawling actually cost you?
AI training bots like Amazon Kendra collect your content to improve future AI models. Unlike AI search bots, there's no direct referral pipeline — Amazon Kendra doesn't cite sources or send traffic back to your site.
What you give
- Server resources for every crawl request
- Your content, expertise, and original research
- Data that improves a competing AI product
What you get back
- No direct referral traffic from Amazon Kendra
- No attribution in AI model outputs
- No revenue share from model usage
This doesn't automatically mean you should block Amazon Kendra. But you need to measure the real cost before deciding. Amazon may send traffic through other products (Amazon's AI products) — blocking the training bot might not affect referrals at all, or it might. Only log data tells you.
