Install Visisto on WordPress
Add the Visisto snippet to your WordPress site header using a free plugin. No coding, no PHP editing, no developer needed.
- A self-hosted WordPress site (or WordPress.com Business plan or above)
- Admin access to your WordPress dashboard
- Your Visisto Site Key. Find it under Sites → [your site] → Manage Site → Advanced options
Your install snippet
Replace YOUR_SITE_ID with your Site Key from the dashboard under Sites → [your site] → Install → Advanced options. Paste both script blocks before the closing </head> tag.
<script>
window.__VISISTO__ = {
site: "YOUR_SITE_ID",
api: "https://api.visisto.com"
};
</script>
<script
src="https://cdn.visisto.com/loader.js"
data-site="YOUR_SITE_ID"
data-api="https://api.visisto.com"
defer
></script>Step-by-step installation
- 1Install the Insert Headers and Footers plugin
Go to Plugins → Add New, search for "Insert Headers and Footers" (by WPBeginner), install it, and activate it.
This is the safest method; it survives theme updates. Alternatively, paste directly into your theme's header.php if you know PHP.
- 2Open the plugin settings
In the WordPress sidebar, go to Settings → Insert Headers and Footers.
- 3Paste the Visisto snippet in the Header field
Copy the install snippet above. Paste it into the "Scripts in Header" text box.
- 4Save changes
Click Save. The script is now active on every page of your WordPress site.
- 5Clear your page cache
If you use WP Rocket, W3 Total Cache, or any other caching plugin, clear the cache now so the script loads on the next visit.
- 6Verify the widget appears
Open your site in a private/incognito window, trigger the widget, and confirm it renders correctly.
- Works with every major WordPress theme: Astra, Divi, Elementor, GeneratePress, OceanWP, and more.
- Do not paste the snippet into functions.php; it gets overwritten on theme updates.
- If you use WP Rocket, go to WP Rocket → Dashboard → Clear Cache immediately after saving.
- The same script covers all your WordPress pages: products, posts, landing pages, and WooCommerce pages.
