For example, when a customer finds you organically through a Google search for example, that means you have some element of authority. When you have authority, prospects are more likely to enter into your funnel because they know that if they found you relevantly, that whatever it is that you're providing must be of a great value. That's just the nature of SEO and organic search. 
Armed with extensive online information, a modern buyer requires different skills from a salesperson and frequently exhibits different behavior than buyers of the past. A modern buyer may get very excited about a purchase and spend a lot of time in the research phase and then abruptly stop, ending the sales process sometimes without any reason at all. Often, modern buyers want to reduce the friction of buying and using a product to make it easy for them to achieve the value.
Have someone examine the ratio of visitors to your page, versus how many people enter their contact information to get access to content. A high percentage means you are targeting your demographic well, and should continue to offer similar content. A low percentage means you need to invest more in adding value to the free content or service you are offering.
When these would-be buyers become interested enough in her products, they request an online demonstration by filling out the form on her landing pages. These requests are routed directly to her salespeople, who, because they’re dealing with warm leads, close roughly 50% of the customers to whom they demo. Molly’s company closes more sales than Norman’s, with fewer salespeople and no time spent on cold calling.

Customers move on to Stage 5 when the sale is complete. Try sitting with your team and brainstorming upon the kinds of information these customers are going to need, as well as how you’ll provide it as part of a cohesive onboarding process. Although at this stage you don’t really need to worry about customers finding you or moving on to the next option, it’s still vital to address their needs so that they walk away feeling good about their purchase decisions.
The sales funnel metaphor is somewhat misleading; in real life, the process never goes as smoothly as liquid down a funnel. In the last decade, digital marketing, artificial intelligence (AI), and CRM have drastically changed the process of converting new leads into customers. Given this, it’s increasingly important that business-to-business (B2B) sales and marketing teams are aligned in their views on a sales funnel strategy and lead generation as a whole.
The marketing funnel depicts the steps of a hypothetical buyer through his decision-making process. The funnel is widest at the top and then gradually grows more narrow. The earliest models depicted a customer entering the funnel as a novice and then sliding down the funnel and through the steps of awareness, interest, desire and action, meaning a purchase.

In a recent conversation I had with Perry Belcher, co-founder of Native Commerce Media, he told me that you also need to train your prospects to click on links. For example, you could have them click on a link of what interests them or link them to a blog post or eventually to a product or service that you're selling, but you need to train them to build a habit of clicking on those links from the very beginning.

As a software engineer myself, I can tell you that building funnels from an application standpoint takes massive amounts of work. There's a great deal of coding and integration that's required here. From email systems to landing page implementations to credit card processing APIs, and everything in between, so many platforms need to "talk," that it takes the bar too high for the average marketer.
