Ads that send people to the homepage
This is how I got into legal marketing. Brenda Clark, a family lawyer I'd worked with on litigation, asked me to look at her ads. You'd click the ad, which she was paying for every time, and it went to the firm's homepage, which wasn't built to capture anyone arriving cold from Google. In most industries, that click would land on a page built to get the visitor's contact details and permission to follow up.
