Has anyone experienced a massive drop in impressions and monthly viewers since 20-01-2021?
Hi @voxdominus & welcome to PBC! Actually I've found the exact opposite... Pinterest has rolled out some new Metrics that might answer what you're experiencing. Read these 2 links & I hope this helps!
Thank you for cooperation!
My pin impressions drop more 100x-500x!
What is the role played by the new metric?
