Your contact page should make getting in touch easy, however the visitor prefers to do it. Offer a phone number, an email address and a short form. If customers visit you, include your address and opening hours.
Keep your business name, address and phone number the same here as on your Google Business Profile. Google says businesses with complete and accurate information are more likely to show in local search results. Your designer can also add LocalBusiness structured data, which is code that tells Google your name, address, phone number and opening hours in a standard format.
Your form collects personal data, so tell people how you will use it. The ICO suggests a short note next to the form, with a link to your full privacy notice.
Test your contact form every month. Send a message, check it arrives and check the reply. A form that silently stops working can cost you enquiries for weeks before anyone notices.
