URL-Based Installation
By default, Arena generates a unique Comment System instance based on your page’s URL. This works out of the box for most websites with clean URLs (e.g., no ?p=123
, utms or tracking parameters).
Prerequisites
Before you begin, make sure you have:
- An Arena account with a registered site.
- Access to your website’s HTML code or CMS admin where the widget will appear.
When to use this method
- Your website has simple, consistent URLs. Requires low to none technical knowledge.
- You don’t need to customize how URLs are handled.
Steps
1. Access Arena's Dashboard
Navigate to Widgets > Comment System > Installation in your Arena account.
2. Add the main script to the website
Add the Comment System main script to the <head>
of your website:
<script async src="https://fast.arena.im/script.js?siteId=[YOUR-SITE-ID]"></script>
The parameter[YOUR-SITE-ID]
will automatically be filled with your account information when copying this information from the dashboard panel.
Recommendation
We recommend placing the main script on all pages of your website. This will improve the analytics features and provide better user behavior insights
3. Add the div snippet to the blog
The snippet must be added to the template or master page of the posts so that it is automatically included in each post. It's also possible to add snippet individually to specific blog posts if you don't want it to appear on all of them.
<div class="arena-comments-widget" data-site-slug="[YOUR-SITE-SLUG]"></div>
The parameter[YOUR-SITE-SLUG]
will automatically be filled with your account information when copying this information from the dashboard panel.
4. (Optional) Include or exclude query params
