How to add Intercom to your website
Intercom is a customer messaging platform for support and onboarding, used by SaaS companies and larger service businesses with a support function. 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 Intercom workspace settings, where the JavaScript installation snippet is provided. For most people the right choice is the messenger widget — the chat launcher and messenger. 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.
Intercom: which option to use
| Option | What it does |
|---|---|
| Messenger widget | The chat launcher and messenger. |
| Help centre | A hosted knowledge base, which deflects a large share of chats. |
| Product tours and outbound | Proactive messages, mainly relevant to software products. |
Step-by-step
- 1
Find the code or link in your account
Intercom keeps this in your Intercom workspace settings, where the JavaScript installation snippet is provided. 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. Messenger widget: The chat launcher and messenger. Help centre: A hosted knowledge base, which deflects a large share of chats. Choosing before you paste saves rebuilding the section later.
- 3
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
- ▸Intercom is expensive and priced for scale. For a small service business it is substantially more than the job requires.
- ▸The widget is heavy. On a marketing site where most visitors never chat, that cost is paid on every page load.
- ▸Its value is in support workflows and onboarding, not in being a chat bubble on a brochure site.
- ▸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
Is Intercom overkill for a small business?
+−
For most, yes. It is priced and built for software companies with ongoing support and onboarding needs. A small service business gets the same practical benefit from a free chat tool or a WhatsApp button, at a fraction of the cost and page weight.
How do I install Intercom on my site?
+−
Copy the JavaScript snippet from your Intercom workspace settings and add it to your site's code before the closing body tag. For logged-in users you also pass identity data in the snippet, which is what enables Intercom to tie conversations to accounts.
Do I need a developer to add Intercom 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 Intercom 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.
