Frequently Asked Questions
What Traffic Patterns Should I Expect From Greppr Web Crawler?
Greppr Web Crawler follows an algorithmic schedule shaped by your site's popularity, update cadence, and domain authority. It generally spreads requests across recurring crawl passes, throttles itself to limit server load, and respects crawl rules more reliably than most other bots.

Greppr Web Crawler is expected to follow robots.txt rules, so a disallow rule is the appropriate first step if you want to block it. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether Greppr Web Crawler respects it.
Is Greppr Web Crawler Used for AI Model Training?
Not ordinarily. Greppr Web Crawler is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
