The 'View Old Site' option offers a simple way to view old and Ezoic versions of your site, for comparative and testing purposes.
To access this setting, navigate to the EzoicAds app in your Ezoic Dashboard and select 'Split Testing' from the left-hand side. Here, you will be able to see the 'View Old Site' tab, where you can turn on this option:
When turned on, you can then select View Old Site. This will set a cookie on your local browser that will allow you to only view an original version of your site.
You can also select View Optimized Site. This will set a cookie on your local browser that will only allow you to view an optimized, Ezoic, version of your site.
You can then select to View Old Site. This will cookie your browser so you always see your original site. You can switch back to seeing the Ezoic version by following the same steps, but selecting View Optimized Site instead.
