User-agent.
Disallow: /search/

• Randomly switch browser fingerprints
• Avoid whole time crawling (alarms are easily triggered during peak hours)

That's when ipipgo'sScenario-based IP packagesIt will come in handy to automatically adapt to the anti-crawl strategy of different websites, so that you don't have to toss it yourself.
