1Create a project for the client's site
In Scopepin, add a project and list every address the site runs on: any staging address your host gives you and the live domain.
The script only accepts feedback from the addresses you list, so a copy of the line pasted on another site does nothing. List client.com and it covers www.client.com too. The project page then shows your install line, with the project's own key in place of sp_….
2Paste the line into WordPress
Install the free WPCode plugin, open Code Snippets, then Header & Footer, paste the line into the Footer box, and save.
In your WordPress admin, go to Plugins, Add New, search for WPCode (it used to be called Insert Headers and Footers), install it and activate it.
If your theme has its own setting for scripts in the footer, that works too. Avoid editing the theme's files directly: an update would remove the line.
<script src="https://scopepin.com/w/v1.js" data-key="sp_…" async></script>3Publish, then test it yourself
Publish the site, open it, click Feedback and pin a comment. It appears in your dashboard with a snapshot of the page.
If the site uses a caching plugin or host caching, clear the cache after saving, then open the site in a private window. The first time you send, the widget asks for your name and email, the way it will ask your client. Nobody needs an account.
What happens next
Each comment is checked against the scope you agreed with the client. The ones that go beyond it are flagged privately, and you can bundle them into a priced change request your client approves from a link.
Questions
Do my clients need a login?
No. They click Feedback on the site, pin a comment and type their name and email the first time. That's it.
Will it slow the site down?
The line loads after the page, and the part that captures the page snapshot only loads when someone sends feedback.
Does it work with page builders like Elementor or Divi?
Yes. The line goes in the site-wide footer through WPCode, so it shows on every page whichever builder made it.
Does it work on WordPress.com?
On WordPress.com, adding plugins and scripts needs a plan that allows plugins. Self-hosted WordPress works on any host.
How do I remove it after launch?
Delete the line where you added it and publish. The feedback you collected stays in your dashboard.
