How to Integrate Calendly or Google Calendar Into Your Website

You have a contact form on your site, yet bookings keep slipping through messages, calls and DMs. Someone writes "I'd like Tuesday at 3", you reply two hours later, and by then the slot is gone. The fix isn't more discipline, it's a system: the visitor picks their own time from a calendar that already knows when you're free.

In this article I'll show you, in plain terms, how to connect Calendly or Google Calendar to your website so every booking lands automatically in your own calendar. No complicated code, no useless subscriptions. I'll explain the difference between the two options, how to avoid double bookings, and the mistakes most people make when they add a "Book now" button to their site.

Calendly vs. Google Calendar directly: which to pick

There are two approaches, and confusing them is what stops most people.

• Google Calendar is your actual calendar, where you see every event. It isn't built for people to book into it directly, but Google has a separate tool, Appointment Schedule, that creates a public booking page tied straight to your calendar.
• Calendly is a separate layer that sits on top of your calendar. You connect it to Google Calendar (or Outlook), and it shows only your free slots and writes the booking back into the calendar automatically.

Simple rule: if you want something fast and free and already use Google, start with Appointment Schedule. If you want finer rules (buffers between meetings, different service types, automated confirmations), Calendly is worth it. Both write the booking straight into your calendar.

Connecting the calendar so you never double-book

The most important part, and the most overlooked, is two-way sync.

That means the booking system must read your calendar to hide already-taken hours, AND write new bookings into it. If either direction is missing, you get the nightmare: two clients on the same slot.

In practice:

• In Calendly, when connecting your Google account, tick the calendar (or calendars) you want it to check for conflicts. If you keep a separate personal calendar, add it to the check, otherwise Calendly won't know you're busy on Saturday.
• In Google Appointment Schedule, existing calendar events automatically block those slots.

Test it yourself: put a fake event at a given time and see whether it disappears from the booking page. If it does, the sync works.

Adding the booking button to your site

You have two ways to show it, and the choice affects how many people actually book.

• Simple button / link: a "Book now" button that opens the booking page (Calendly's or Google's) in a new window. Simple, works on any site, including WordPress or a static page.
• Embed (the calendar built into the page): booking appears right inside your site, without leaving the page. It converts better, because the visitor isn't sent to another domain.

For an embed, Calendly gives you a small snippet you paste into the page. Google also offers a "Book now" button. Practical tip: place the button near every section where people decide, not just hidden on the contact page. The best calendar in the world doesn't help if the button is hard to find.

Notifications, confirmations and fewer no-shows

A booking landing in the calendar is only half the job. The other half is the person actually showing up.

Both systems automatically send a confirmation email and can send reminders before the meeting. Set them up:

• An immediate confirmation email with the date, time and, if relevant, the online meeting link.
• A reminder the day before and, ideally, another one a few hours before.
• A one-click reschedule / cancel option, so the person frees the slot themselves instead of just not showing up.

If you work with clients who prefer WhatsApp or SMS, note that native reminders are usually by email. For phone messages you need an extra integration, and here it's worth not overcomplicating things unless you genuinely have many no-shows.

How we handle this at MPO Web Studio

At MPO Web Studio we work remotely, with clients across the country, and setting up a booking system is a common request, especially for salons, clinics and appointment-based services.

Our approach is simple and transparent: we first build you a free demo, with the booking button already placed and connected, so you see how it looks on your own site before you pay anything. We choose together between Calendly and Google Calendar based on how you work, not on what's more expensive.

If you want your bookings to land in your calendar on their own, without juggling your phone, send us a message on WhatsApp. We'll tell you honestly what fits and what it costs, with no inflated promises.
