Screaming Frog: Custom Search Feature

We introduced the Screaming Frog application and its basic functionality in our Screaming Frog Simplified blog post. This time, we want to show you how to enhance your search capabilities using its Custom Search feature. The Custom Search option can be found in the main menu under Configuration > Custom:

Searching for Tracking Code

A common use of the custom search feature is to find which pages contain Google Analytics, Google Tag Manager code, or any other tracking code.
