The marketing and sales funnel is called a “funnel” because of the hypothetical shape it would take were it an actual physical object. It’s a funnel because of how many contacts you begin with at the very top. As these contacts are nurtured into leads and qualified through each stage of the funnel, the number will naturally reduce. A portion of your leads will drop out at each stage as a result of finding a different solution, losing interest in your company, or not being qualified in some other way (such as not having the budget or decision making abilities to convert). Because of this, the funnel size naturally shrinks from one stage to the next, resulting in a funnel-like shape.
Unfortunately, if there is an issue with your marketing or sales processes, it can cause the funnel to be misshaped. For example, if the middle of the funnel is too skinny, it means that your visitors aren’t converting to leads or your leads aren’t becoming more qualified and getting closer to becoming a sales qualified opportunity. This can be the result of targeting the wrong audience and may require you to revisit (or develop) your buyer personas. If the middle of the funnel is too bloated, it means that your leads are getting stuck in the funnel. This can happen if you’re not properly qualifying leads for the next stage. It can also occur if you’re having issues addressing your prospects’ needs to nurture them through to the next stage of the funnel by providing them with value and compelling reasons to do business with your company.
Finally, if the end of the funnel is too small, it may mean that your leads are being handed over before being sales qualified or because there’s an issue with your sales process, which is leading to fewer sales opportunities and ultimately fewer than expected new customers.
