HTML Code Injection

The URLsLab Code Injection module is a powerful and straightforward feature that lets you insert HTML, Javascript, or CSS code into your WordPress page. It enables you to add custom integration codes to your web page instantly without altering your page’s HTML templates. In just a few seconds, you can establish the injection rules, switch them on/off, and implement the code only on certain pages that meet your conditions. There’s no need to consult developers or wait for days for your WordPress updates.

With this module you can easily modify response from your web server:

  • HTTP headers – add or change web server response headers
  • Add custom HTML at the beginning of page head tag – right after <head> tag
  • Add custom HTML before </head> tag
  • Add custom HTML at the beginning of HTML body – right after <body> tag
  • Add custom HTML at the end of the page – before </body> tag

Thanks to flexible settings you can inject HTML to all HTML pages on your website or just some specific pages matching your conditions.

When will I need to inject HTML or JS to my WordPress page?

Each time you need to integrate additional external service or application to your WordPress page, you are asked to copy and paste small HTML or javascript code to your HTML WordPress template. For some WordPress users it could be hard to find the correct place, where should be included such code. Or sometimes you want to add the integration just for limited amount of time or easily activate/deactivate it based on your requirements.

Example of integrations:

  • tracking applications – e.g. Google Analytics, Google Tag Manager, affiliate software (e.g. PostAffiliatePro)
  • customer support applications – contact forms, live chats, call buttons (e.g. LiveAgent), or signups to newsletters
  • GDPR consent dialog
  • A/B testing tools
  • etc.
