When working with generated archive pages, it can be difficult to get all the Twitter meta tags that you want to be added to a specific archive page.
Specifically, when using a plugin like Yoast SEO to manage Twitter meta tags, there is no way to set a custom Twitter image to appear on an archive page like the one we use for our main Coupon Archive Template.
That’s why we have an option to set a custom image for the Twitter meta tag that be printed out specifically on the Coupon Archive Template.
This is only relevant when using our Coupon Archive Template and does not apply when using the archive shortcode on a regular page.
