In the Page editor you can easily make your own snippet preview and choose how you want the Snippet Preview to look like in google.
The great thing about this, is that you can manually make the snippet preview.
My website is going to be changed now and before I do that I need some information.
I am going to place the textual content (page editor) in content boxes and in other sections.
That means I can't set the Snippet Preview manually anymore, because with the content box and other sections there is no possibility to set it.
I wonder how you (members of pageline) have set the snippet preview for the pagelines website, Pagelines also makes use of Yoast Seo Plugin.
