The Click Share score reflects the percentage of searchers who may click on your website, if listed in the Top 20 positions from the SERPs. The metric is calculated considering the 2016 Organic CTR Study exact data, for Desktop International searches. The estimates are assigned differently, depending on the keyword length (long tail / mid-length or head term).

The CTR Study shows that 33.27% of searchers will click on the 1st position from SERPs, when browsing for a head term (1 word). Percentages are gradually assigned for positions 2-20, with keyword length variations.

For positions below Top 10, less than 1.5% of searches results are being clicked. The estimated Click Share for positions out of Top 20 is 0.

Click Share is represented as an aggregated metric, for all keywords and monitored search engines, but it can be also calculated per group of terms and / or search engine.

CS formula: 

kwd 1 + kwd 2 + kwd 3 + ....+ kwd "n" / n -> CS value for a given set of keywords, for one search engine 

where kwd "n" = no. of keywords in set / group

for each kwd, the proper ClickShare value is added (see gradual assignment / position and keyword length)

*When a website ranks with multiple URLs for the same keyword, only the best position is considered.

The global ClickShare, across all added search engines is computed by aggregating the granular ClickShare scores / keyword, on each of the monitored search engines.
