It places your tracking code exactly where it needs to be: * **Script tag** injected into `` — synchronously, without `async` or `defer`, ensuring Lead Forensics and dependent tools like LF Chat load correctly. * **Noscript tag** injected immediately after the opening `` tag — the correct position per the HTML specification. **Why does placement matter?** Many WordPress performance plugins add `async` or `defer` to any script they find. This breaks Lead Forensics tracking and any tools that depend on the visitor data it provides. This plugin bypasses the WordPress enqueue system entirely, giving you reliable, consistent injection every time. **Fonctionnalités** * Separate fields for Script Tag and Noscript Tag * Automatic stripping of `async` and `defer` attributes on save * Live preview of exactly what will be injected * Tracking status indicator — see at a glance whether your code is configured * Direct link to your tracking code in the Lead Forensics portal ## Installation 1. Upload the `lead-forensics-roi` folder to `/wp-content/plugins/` 2. Activate the plugin via **Plugins** in WordPress admin 3. Go to **Settings Lead Forensics** 4. Paste your Script Tag and Noscript Tag from the [Lead Forensics portal](https://portal.leadforensics.com/TrackingCode) 5. Click **Save Changes** ## FAQ ### Where do I find my tracking code? Log in to your [Lead Forensics portal](https://portal.leadforensics.com/TrackingCode) and navigate to Settings Tracking Code. ### Why are there two separate fields? The script tag must go in `` and the noscript tag must go immediately after` `. Putting both in the head (as some plugins do) is invalid HTML and causes inconsistent behaviour across browsers. ### Will this work with caching or performance plugins? Yes. Because we bypass `wp_enqueue_script()` and echo directly into the relevant hooks, caching and optimisation plugins cannot modify or defer our output. ### My theme doesn’t support wp_body_open — will the noscript tag still work? The noscript tag requires your theme to call `wp_body_open()`. All themes from WordPress 5.2 onwards support this. If your theme does not call it, the noscript tag will not render — however this will not break your tracking, as the noscript tag is only a fallback for visitors without JavaScript. ### Does the plugin collect any data? No. The plugin stores only the two tracking code snippets you paste in (in your own WordPress database). It does not collect, transmit, or store any user data itself. ## Avis ![](https://secure.gravatar.com/avatar/313c638c239590bf43666f0befd50855401b9083cf1b246b6a3596e1df2e7d8b? s=60&d=retro&r=g) ### 󠀁[The plugin worked fine for me.](https://wordpress.org/support/topic/the-plugin-worked-fine-for-me/)󠁿 [Website Dude](https://profiles.wordpress.org/modernscarface/) 7 novembre 2018 The plugin worked for me and did as it was expected to do. ![](https://secure.gravatar.com/avatar/56b728732c63cbd2bc50844a3ced43c1469588d08e315516b352b28565f0fd5c? s=60&d=retro&r=g) ### 󠀁[Works](https://wordpress.org/support/topic/works-1459/)󠁿 [maxoncos](https://profiles.wordpress.org/maxoncos/) 20 août 2018 Worked without issue on my site. ![](https://secure.gravatar.com/avatar/695ef6c44099c364f067135437cd8ee599d0e20dc8bb159db1b5fe00d04603ca? s=60&d=retro&r=g) ### 󠀁[Broke my site](https://wordpress.org/support/topic/broke-my-site-151/)󠁿 [johadretri](https://profiles.wordpress.org/johadretri/) 11 mai 2018 after installing this plugin, it gave me the classic wordpress white screen of death. the tool itself seems useful but not worth the damage once disabled site works ok again. if a later release fixes this issue ill be happy to give it another try ![](https://secure.gravatar.com/avatar/afc3436a88725d2e82396cdf2b26751f57744567e72fdbc742d38f47618deb3c? s=60&d=retro&r=g) ### 󠀁[Just Works](https://wordpress.org/support/topic/just-works-231/)󠁿 [RupertGB](https://profiles.wordpress.org/rupertgb/) 3 septembre 2016 Paste the code in the box.
