Do you think adding the rel=Author can have a negative impact on either the SERPs or the Click Through Rates?
On some article content we noticed no change in the SERPs, no change in the amount of searches but a 50% drop in CTR (click through rate). It was on April 25. A few days earlier we connected our G+ profile to these articles.
Please note that CTR can also change due to layout changes on the search result pages. Did someone notice layout changes on April 25?
Has anyone experienced a sharp drop in CTR without changes in SERPs?
