CTR is the number of clicks on your CTA button, versus the total visitors to that landing page or ad. If 1000 people visit your landing page/view your ad, and 650 people click on the CTA, your CTR is 65%. A high CTR depends on a number of factors, chief among which are the value proposition on your page/ad, your CTA’s placement, and the relevance of your content vis-à-vis your target audience.
Leads may come from various sources or activities, for example, digitally via the Internet, through personal referrals, through telephone calls either by the company or telemarketers, through advertisements, and events. A 2015 study found that 89% of respondents cited email as the most-used channel for generating leads, followed by content marketing, search engine, and finally events. A study from 2014 found that direct traffic, search engines, and web referrals were the three most popular online channels for lead generation, accounting for 93% of leads.
