Facebook has been a method for lead generation since its inception. Originally, companies could use outbound links in their posts and information in their bios to attract strangers to their websites. However, when Facebook Ads was launched in 2007, and its algorithm began to favor accounts that used paid advertising, there was a major shift in how businesses used the platform to capture leads. Facebook created Lead Ads for this purpose. Facebook also has a feature that lets you put a simple call-to-action button at the top of your Facebook Page, helping you send Facebook followers directly to your website.

The best services offer a combination of self-serve help resources—where you can search FAQs and articles to find your own answers—as well as live support via chat or phone when you can't solve an issue yourself. We cover all of these concerns in our reviews, plus you can get an overview in the feature chart above.
