What is the main reason why it is hard to measure the ClickThrough Rate (CTR)?
Hi,
Click-Through Rate (CTR) is a performance metric expressed in percentages that measures the number of times an ad, organic search result, or email is clicked versus the number of times it has been viewed (impressions). It is most commonly used to measure the effectiveness of paid search, display and email marketing campaigns and can indicate the performance of ad copy, subject lines, and metadata (titles and descriptions).
To determine the Click-Through Rate of your campaign, you need to divide the number of total impressions by the number of total clicks and multiply by 100.
And, it is very hard to measure it just because of the above reason that is it's very hard to get the data on number of total impressions, I agree with you that it;s very easy to get the total number of clicks but it's calculation also needs numner of impressions and hence, it becomes difficult to measure.
