Weebly
If you use the Weebly website builder to power your website, you can easily add the Live Assist javascript tag to all pages of your site. To do so, first click the Settings tab at the top of the Weebly console and then select the SEO option from the left hand side menu bar.
As in the image above, you should now see a series of text boxes, with one for Footer Code. Simply paste in your Live Assist tag there and click publish to deploy to your live site.
Wordpress.org
Wordpress powered websites come in two variants. You can use Live Assist in both. For users using the open-source self-hosted version (wordpress.org) to power their website, you can easily Live Assist enable your entire site by adding the Live Assist tags either to your theme code or as widget to specific areas of your site. The images below guide you through adding the tag by editing your theme code, it's worth noting that if you do change your theme in future you will need to repeat this process, and by creating a custom HTML widget for your footer.

Wordpress.com
If you are using the cloud hosted worpress.com platform version of WordPress to power your website. So long as you have a Business Plan subscription, you can use third party plugins (e.g. https://en-gb.wordpress.org/plugins/header-and-footer-scripts/) to insert the Live Assist tags in all pages across your site.
Shopify
If you use shopify to power your e-commerce website, then you can Live Assist enable your pages, by adding the LA script tag to your theme. To do this, you need to customize your theme and select the edit code feature from the more actions drop down, as per the image below:
Once you are in the editor, you should be able to add the LA javascript tag to your theme.liquid file, say before the closing </body> tag, as per the image below:
Caveat: Shopify does not let you run custom javascript through the checkout flow pages, for PCI compliancy / security reasons. So you should bear this in mind when setting up your campaigns / engagements. You can, however, customize the check-out flow if you have a Shopify Plus Plan.
Wix
Unfortunately, at the time of writing, the Wix editor does not allow you to embed custom javascript pages within the DOM of your site or pages. You may only add custom code to small areas (iframes) of pages, which does not support the Live Assist experience very well.
Microsoft Portals
Live Assist for Microsoft Dynamics 365 can also be embedded into Microsoft Portals. There are several benefits of this which you can read about under Why Integrate with the Customer Portal . You can also read about How To Enable your Customer Portal
