This plugin creates a full screen ad with an expiration date without cloaking. All you have to do is add a link, image and expiration and you can have a full screen ad with a cookie.
There are plugins out there that create separate full page ads or landing pages versus what Google sees. So the plugin would show the user one page while showing another page to a search engine. This can be called cloaking which is never really a good strategy to show ads or landing pages.
This plugin doesn’t create landing pages. This plugin creates full page ads to promote your product or service without cloaking.

Content Expiration is a WordPress plugin that allows authors/editors to set an expiration date on posts or pages. The plugin is intended to be simple with easy-to-read code.
An expiration can be set by specifying a number of days (e.g., expire in 90 days) or a specific date/time (e.g., May 10, 2018 at 10:00 PM). Two weeks prior to the expiration date, the author of the post/page is sent a warning email. The author receives another notification email upon expiration.
When a post/page expires, it is not deleted. Instead, it is given a status of Expired and hidden from public view. Visitors to the site will receive the regular WordPress 404 Page Not Found error.
The expiration can be reset by any editor or administrator of the site. They must log in and edit the expiration settings of the post/page.
Content Expiration is developed on GitHub. Please submit bugs reports and contributions on <a href="https://github.com/srguglielmo/Content-Expiration" rel="nofollow ugc">the GitHub Project page</a>.
For general support and questions, please use the <a href="https://wordpress.org/support/plugin/content-expiration/" rel="ugc">WordPress support forum</a>.
