Every part of your sales funnel is trackable. Once your funnel is launched, you'll be monitoring how the traffic flows...
...Not every person that goes through your funnel is going to reach the other end and convert and that's fine.
It's normal to get a lot of people enter the funnel, but see the numbers reduce further down the line. But the ones that get to the end are highly qualified and 100X more likely to turn into customers
A funnel will weed out those that aren't serious and only those that are genuinely interested will get to speak with your sales team. You won't be wasting time on those cold unqualified leads any more!
You'll know your numbers - so your growth becomes predictable and under your control.
You'll know how many people need to enter the funnel to generate each new customer.
You'll know your exact return on your ad spend. It's a beautiful place to be when you know how much you'll make for every pound that you spend on ads, you get a 2, 3, 4... or more X return.
Then you simply decide how many new customers that you can handle and pour the required amount of traffic in at the top.
You're buying new customers at a rate that suits you.
It's a numbers game and you're in control.
