Cost per thousand (e.g. CPM Group, Advertising.com), also known as cost per mille (CPM), uses pricing models that charge advertisers for impressions — i.e. the number of times people view an advertisement. Display advertising is commonly sold on a CPM pricing model. The problem with CPM advertising is that advertisers are charged even if the target audience does not click on (or even view) the advertisement.
Unsurprisingly, the more revenue a company has, the more leads they generate. The differences are most drastic at the highest and lowest end of the spectrum: 82% of companies with $250,000 or less in annual revenue report generating less than 100 leads per month, whereas only 8% of companies generating $1 billion in annual revenue report less than 100 leads per month.
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.
