How to add Facebook Messenger chat to your website
Facebook Messenger chat is Meta's chat plugin connecting website visitors to your Facebook page inbox, used by local businesses whose customers already message them on Facebook. Here's how to put it on your own website, which embed option to pick, and what goes wrong.
Quick answer
Get the code from your Facebook page settings under Advanced Messaging, where the chat plugin is configured and its code generated. For most people the right choice is the chat plugin — a floating chat bubble connecting to your page inbox. Paste it into a code or embed block on your site — not a plain text field — then place it beside your main call to action and test the whole flow on a phone before relying on it.
Facebook Messenger chat: which option to use
| Option | What it does |
|---|---|
| Chat plugin | A floating chat bubble connecting to your page inbox. |
| Click-to-Messenger link | A plain m.me link behind a button, with no script at all. |
| WhatsApp instead | Usually the better choice outside the US — most customers prefer it. |
Step-by-step
- 1
Find the code or link in your account
Facebook Messenger chat keeps this in your Facebook page settings under Advanced Messaging, where the chat plugin is configured and its code generated. Copy what you need before touching your website — most of the time people lose is spent hunting for the snippet, not installing it.

Pick the right option for the job
The table above is the decision. Chat plugin: A floating chat bubble connecting to your page inbox. Click-to-Messenger link: A plain m.me link behind a button, with no script at all. Choosing before you paste saves rebuilding the section later.

Paste it into a code or embed block
This needs an HTML, code or embed block — not a plain text field, where the code will simply appear as text on your page. On Adviita, ask the AI editor to add an embed section and drop the code in. On WordPress use a Custom HTML block, on Squarespace a Code block (Business plan or above), and on Wix an Embed HTML element.

Put it where the decision happens
A messaging option is only an asset if someone answers it. An ignored chat is worse than none. A widget three scrolls down does a fraction of the work of the same widget beside your main call to action. Decide what the page is for, then place it at the point the visitor is deciding.

Check it on an actual phone
Most visitors to a small business website arrive on a phone, and embeds are where mobile layouts break. Open your live site on your own phone and confirm it loads, fits the screen without sideways scrolling, and does not push your contact button out of view. Third-party embeds are also the most common cause of a slow page, so if it noticeably delays loading, consider a plain link instead.

Test it end to end before you rely on it
Run through the whole flow yourself as a customer would — send a real message — and confirm what should happen actually happens. Broken embeds fail silently, and the first person to notice is usually a customer who has already given up.
Tips & best practices
- ▸Visitors must be logged in to Facebook for the plugin to identify them, and many are not. The guest mode experience is worse.
- ▸The plugin loads Meta's SDK, with the usual page speed and cookie consent implications.
- ▸In most markets WhatsApp gets far more engagement than Messenger. Check which your customers actually use before choosing.
- ▸Re-test the embed after any change to your site, your plan, or the connected account — third-party widgets break quietly and nothing tells you.
Common questions
Should I use Messenger chat or WhatsApp on my website?
+−
In most markets outside the US, WhatsApp. Engagement is significantly higher because it is where people already message businesses, and a WhatsApp link needs no script, no login and no cookie consent. Messenger makes sense if your audience genuinely lives on Facebook.
How do I add Messenger chat to my website?
+−
In your Facebook page settings, open the advanced messaging area and configure the chat plugin, adding your website domain to the allowed list. Copy the generated code into your site. Alternatively, skip the plugin and put a plain m.me link behind a button.
Do I need a developer to add Facebook Messenger chat to my site?
+−
No. Every option here is copy and paste into a code or embed block, which every mainstream website builder provides. The only genuine blocker is a builder or plan that does not allow custom code at all — Squarespace, for instance, requires a Business plan or above for code blocks.
Will adding Facebook Messenger chat slow down my website?
+−
Any third-party embed has some cost, because it loads code from another company's servers. One is usually unnoticeable; four or five on the same page is where small business sites become visibly slow. If page speed matters to you, prefer a plain link over a script wherever the option exists, and keep embeds to the pages that genuinely need them.
