Averages, as shown in the diagram above, distort the reality. They just show that, the average. The real click-through rates can look very different in your keyword environment and in your industry. Therefore, we took an additional big step in this analysis and evaluated the CTR for different SERP layouts.
By SERP layout we mean the specific composition of a Google results page (SERP). This consists largely of the classic, organic results, but is increasingly enriched with other boxes and features.
In this post, we focus on the most popular SERP layouts. For those, we take the first SERP result presented and remove keywords whose results pages consist of a combination of different feature boxes. This way we get comparable and clean data.
