-my client has large eshop with underwear, swimsuits etc.
-He spends tons of money on PPC
- Q1 2018 vs Q1 2017 more than 100% increase on PPC traffic and good revenue
-Q1 2018 vs Q1 2017 his organic traffic dropped around 40% compared to last year
* around December 2017 he redesigned the whole site can this be a reason?
