WP Splash Page is a WordPress plugin that adds a fully customizable splash page to your website.
You can set up the plugin by choosing the text color or the background image among other things. It also provides you with some important features like age validation. Bots can’t see the splash page. Instead, they go directly to the original page. By this way you won’t lose ranking and visibility in search engines. This isn’t a plugin for Maintenance Mode!
