Getting potential clients to book consultation

My conversion rate for signing new clients is like 80%....AFTER we are able to chat on the phone/zoom for an initial consultation. I'm happy with those numbers. However, I've been having difficulty getting people to even sign up for those initial consultations.

I have been advertising on list-serves, with some success. After a single post/ad, I will have many people click the link that takes them to my website. They will then click the "contact me" button, and then fill out a brief form that sends their inquiry to my email. I email them back either that same day or the next day (depending on how late I get their inquiry) with a Calendly link to schedule time for a consultation. It's that Calendly link that I can't get them to click.

My reply emails are as follows:

  1. Thank them for reaching out

  2. A quick sentence that my specialty matches what they are specifically looking for/compliment them for thinking ahead.

  3. Very occasionally an estimate of my fee if they specifically ask for it

  4. A link for them to schedule a brief, free consultation. I also state that the consultation take place over Zoom or phone.

Why would a potential client go through all of the clicks to click my website, click "contact me," and fill out the questionnaire, without then booking a free consultation?
