The European laws are changing. Although the United States is a bit behind, we are sure they will be catching up. European law now states that web publishers must include the General Data Protection Regulation (GDPR) warning which gives visitors information about cookies and other forms of data storage that might be contained within their websites.
WordPress
Our platform for developing websites is usually WordPress. One of our favorite plugins to help comply with the GDPR is Cookie Notice for GDPR by dFactory. Used by over a million websites, it is one of the easiest to install and work with. It includes lots of features for linking to your Privacy Policy, colors, and positioning of the notice.
