Google Tag Manager is the easiest route when you, or your marketing team, can publish tags but cannot edit the site's code. The Selo Assist widget is a single script tag, which is exactly what a Custom HTML tag is for.
Once it is published, the assistant appears on every page where your container loads.
How to set it up
- 1
Create your assistant
Sign up and add your website address so the assistant can read your pages.
- 2
Allow your domain
Add your site's domain under Allowed websites on the Widget page.
- 3
Copy the embed code
Copy the one-line script tag.
<script src="https://chat.siteselo.com/widget.js" data-workspace="pk_..." async></script> - 4
Create a Custom HTML tag
In your Tag Manager container create a new tag, choose Custom HTML, paste the code, and set the trigger to All Pages. Use Preview to check it fires, then Submit and publish the container.
- 5
Check it
Open your site in a private window. The chat button appears once the container has loaded.
Why it works
No developer needed
Whoever manages your tags can install, pause or remove the widget.
Choose where it shows
Use a different trigger to show the assistant only on chosen pages, such as your pricing or contact page.
Same security
The widget still only loads on the domains you allowed in your Selo Assist account.
