It feels sensible to collect everything up front: ask now, avoid asking later. But the person filling in the form is in the opposite position. They have not yet decided to spend time on you.
A field is not a feature, it is a question. Each one makes the visitor pause over “why do you need this?”, and those pauses accumulate into an exit rather than a submission. The direction is clear enough — but a percentage lift quoted from someone else’s site is their number, not yours. Measure your own.
A form is the start of a conversation, not a contract
Restate the goal. The purpose is not data collection, it is getting into a state where you can reply. Read the field list against that and it shortens itself.
Choosing what stays
Test each field with one question: “without this, can I write the reply?” If not, keep it. If yes, cut it.
For most businesses the reply needs one contact method and one line of context. A name is worth keeping so you can address someone properly. Company, job title, budget band and preferred dates almost always arrive naturally in the first exchange.
There is one exception: if your service has eligibility conditions, a field that filters out enquiries you cannot accept is kinder to both sides. If the work requires a particular hosting arrangement, asking which kind they have removes an awkward rejection later. Even then make it a radio button with a few options — a free-text box raises the barrier without improving the answer.
What you must do instead
Shortening the form genuinely gives you less information. You repay that with the quality of the reply.
The auto-reply says “received, and here is when you will hear back”. Without it the visitor cannot even tell whether the submission worked. The first human reply is where you ask for the missing details — and only for what the next step requires, not all of it at once.
Three common mistakes
First, marking everything required. Leave optional fields optional; the people who want to fill them in still will. Second, unhelpful validation. If the form will not say which box is wrong and why, that is where the enquiry ends. Third, no confirmation screen. The thank-you page is not a courtesy, it is evidence that the submission worked.
And a perfect form is worthless if the mail never arrives — delivery failures are extremely common on WordPress sites, and the causes and fixes are covered across the SEO and Servers & infrastructure archives. If you would rather have the whole path from form to inbox checked in one go, it is part of the diagnostic in our optimization program.
