Match the page to one campaign goal
A landing page should answer the promise made in the advertisement and lead to one primary action. A booking campaign needs availability and booking details; a consultation campaign needs a clear explanation of who the service suits. Sending every campaign to the same general homepage makes it harder for visitors to find the relevant answer.
What to prepare and how to review the result
Prepare the offer, audience, source advertisement and the information needed to qualify an inquiry. Keep required form fields limited to what you actually use. Test the confirmation message and delivery to the sales team. Compare qualified inquiries against advertising spend; a large number of form submissions can still be poor performance if those visitors are not suitable customers.
The final scope, cost, schedule and included files are defined in a written proposal before work starts. Use these points to explain your needs and compare proposals against the outcomes you require.
