If you take texts, say so on your site.
Plenty of owners text customers all day. Your site still only shows a phone number and a form.
Most owners already text. A customer asks if you can come Thursday. You text back yes. Another asks for a photo of the part. You text the photo.
Then someone new lands on your site. They see a phone number and a contact form. They do not see that texting is fine. So they call. Or they fill out the form and wait. Or they leave.
Put it in plain words
Near the phone number, add one short line. Something like: Text is fine. Or: Call or text.
If you only text during work hours, say that too. If you want photos sent by text before you quote, say that. People will do what you ask when the ask is on the page.
Keep the number the same one you answer
Don't invent a second “text only” number unless you really use one. One number that you actually pick up is better than three that go nowhere.
Match what you do on the phone
If you hate texting, don't advertise it. If you live in your messages app, put that on the site so the next customer starts there.
If you want a site that says texting is fine next to your number, talk with Hexacomb. You run the business. We take care of your website.
