Not all your content might be suitable for children or young users. If you are planning to show adult content on your website, you need to make sure people know what they are going to be dealing with. Adding age verification to sites with those types of content is a must-do practice. AGE-Gate for WordPress makes that possible.
AGE Gate for WordPress lets your visitors verify their age before entering your website. This way, you will remind your young visitors that the material that you have may not be suitable for them. Of course, that does not always stop people from trying. The plugin lets you enter minimum age information for multiple countries and have it enabled globally. You can also define a redirect URL.
AGE GATE for WordPress is not bulletproof but does remind your visitors to avoid your content, especially if they are too young for what you have to offer. It is fairly easy to customize and does what it promises.
