LeadOcto runs via a single line of JavaScript that you paste just before the closing </body> tag. This makes your site fetch the current settings on every visit, if you change something in the dashboard, it's immediately live without re-uploading anything.
Step 1, Find the install code
In the widget editor, click 'Get Install Code' at the top right, or jump straight to your widget's Install page.
Step 2, Paste the snippet into your site
Paste the line just before </body> in your HTML. The exact spot depends on your platform:
WordPress
Install a snippet plugin such as 'WPCode' (or 'Insert Headers and Footers') and paste the snippet into the 'Footer' section. Save.
Shopify
Go to Online Store → Themes → Edit code → Layout → theme.liquid and paste the snippet just before </body>.
Wix / Webflow / Squarespace
Open the 'Custom Code' or 'Footer Code Injection' settings and paste the snippet there.
Custom site
Paste the snippet right before </body> in your main template.
The snippet covers every page at once, you only need to add it once.
Step 3, Verify it's working
Open your site in a new incognito window. Within a few seconds the floating button should appear in the bottom-left or bottom-right. Click it and check that your buttons are visible.
Don't see the button? Check that the widget is set to 'Active' in the dashboard and that your browser isn't running a script blocker.
