Derek joins us in this Slack AMA to answer WTSer questions on their research!

If you’ve been to WTSFest Philly or Portland - you’ve likely met the wonderful Derek, Duncan, & / or Boyd of the Nozzle team.
Long-time supporters of WTSFest, when we reached out to the team to share that our community members had questions on their latest research - they jumped at the chance to answer them through this AMA.
Thank you, Nozzle team! 💜

Join us live in the #digital-analytics Slack channel on Tuesday, 10 November at 4pm GMT for an open conversation with Derek Perkins about Nozzle’s Poisoned Google SERPs research & what it means for SEO reporting.
In the latest update to Nozzle’s research, the team analysed 29.9 million SERPs & reported that 22.6% of the SERPs judged on both page 1 and page 2 had been “poisoned” since 13 September. These are complete, normal-looking results pages where many of a keyword’s usual sites were missing.
Page 2 was affected 1.5 times as often as page 1, & the rate reached 43.5% at its peak.
The findings raise practical questions for anyone using rank-tracking data: how do you separate a real ranking change from unreliable collection, explain unusual volatility to stakeholders without creating unnecessary alarm, & check your own reports with confidence?
→ Using rank-tracking or SERP data to monitor performance
→ Responsible for SEO analytics, dashboards or leadership reporting
→ Investigating sudden ranking volatility or unexplained visibility drops
→ or who are just generally curious about the research!
