For example, let’s say your business has a blog and social media accounts it uses to get on a potential customer’s radar. From there, you encourage people to download an eBook in exchange for their email and drop them into an email drip that promotes an upcoming webinar. At the webinar, you sell people on your product or service, which convinces them to submit a lead form, work with your sales team and ultimately make a purchase.
The final stage of the sales funnel is the action that you're intending them to perform. In most cases this is the purchase. Again, how well you move them through the various stages is going to set you up with a specific conversion for this action. For example, if 100 people click on your offer and 10 people enter your sales funnel but only purchase people purchase, then you have a 2 percent conversion.
If you're wondering what a sales funnel is, simply imagine a real-world funnel. At the top of that funnel, some substance is poured in, which filters down towards one finite destination. In sales, something similar occurs. At the top, lots of visitors arrive who may enter your funnel. However, unlike the real-world funnel, not all who enter the sales funnel will reemerge out from the other end.
