If you're a Mediavine Publisher using the Mediavine Control Panel plugin and Trellis as your active theme, you can find these settings by logging into your WordPress site and navigating to Appearance → Mediavine Trellis → MVP
Feed Ad Spacing
This setting will adjust the ad density on the homepage, post feeds and archive pages.
Feed Ads are very similar to in-content ads. They are placed between article excerpt containers in the post feeds of your Trellis theme.
"Post feeds" refers to the default homepage feed and any default archive pages where a list of posts will be displayed. Ads will be served between the post excerpts with the frequency setting you select.
Low = An in-content ad will be targeted after every 6th article in the feed. This will likely result in a single in-content ad per feed or archive page.
Normal = The default Normal setting will target an in-content ad after every 4th article in the feed. This will likely result in up to 2 in-content ads per feed or archive page.
High = An in-content ad will be targeted after every 2nd article in the feed. This will result in the highest density of in-content ads per feed or archive page, with up to 5 in-content ads per feed page.
None = This setting will prevent in-content ads from being targeted to your archive or feed pages. Sidebar ads will still be served.
Show Ads on Pages
This setting will allow ads to display on your Pages.
If you don't want to run in-content ads or featured video on your Pages, you can disable them globally here. If there is a sidebar on the page, sidebar ads will still be served. In-content ads will still be served on posts, regardless of this setting.
