Bot blocking

Pulse Insights attempts to recognize and block bot traffic so that bots don't see impressions, which can skew the reporting/accuracy of survey response rates. Our analysis shows that most client bot traffic is from crawlers such as search engines and security vendors.

There are two primary mechanisms for bot recognition:

  • IP address requests over a threshold within a time window

  • Maximum cumulative impressions for a single Device UDID

The exact values change from time to time to allow for heavy real usage by development and QA teams, while still blocking likely bots.

Once traffic is identified as a bot, Pulse Insights will not return surveys unless explicitly unjailed by by Pulse Insights. Or, once max cumulative impressions for a single UDID is reached, any additional impressions or responses won't be recorded.
