What Is Click-through Rate?
Click-through rate is a digital advertising metric that shows how often people select an advert after seeing it. The metric compares ad clicks with ad impressions and expresses the relationship as a rate. In legal search advertising, click-through rate helps indicate whether the advert and its message match the searcher’s intent.

How Click-through rate Works

Click-through rate is calculated by comparing clicks on an advert with the advert’s impressions. An impression records that the advert appeared, while a click records that someone selected it. The result gives a view of how closely the advert attracts the attention of people who see it.

In Pay-Per-Click Advertising For Lawyers, the metric is read alongside the search term, advert wording, landing page and conversion data. A strong response may show that the message fits the search. A weaker response can point to a mismatch between the searcher’s need and the advert’s promise.

Expert Note
When we manage legal search campaigns, we check click-through rate against the search terms and advert wording. We also review the landing page and enquiry actions, because a click alone does not show whether the campaign produced a useful result.
