Cookies are extremely useful for website owners who want to learn a good deal about user behavior on their sites. They can help provide insight into return visitors, and behavior of these users. They are often used for purposes of creating highly targeted advertising. Cookies can, however, store a large amount of data, which could go against the guidelines set forward in the GDPR. A cookie banner describes the text or text box that comes across many websites on the internet, wherein you must either acknowledge that the site is using cookies to proceed, and to either accept this use, or decline to use cookies. In some cases, you are only given one option (e.g. if cookies are required to use the site). You always have the option of leaving a site that prompts with this.
GDPR stands for General Data Protection Regulation, which is a European Union law which specifies how personal data can be used and processed by a website. It also extends to any members of European Economic Area (EEA). It is designed to protect individuals who wish to maintain some level of control over their personal information and to be able to maintain some level of privacy. The basic stipulations of the GDPR are that organization or person who deals with individual personal data must adapt “appropriate technical and organizational measures” to ensure that data of individuals are protected against inappropriate use. In order to be compliant, anyone who controls data on individuals must disclose any collection of this data to the subjects involved. They must state explicitly how the data is being used, and how long this information is retained. This applies to the use of a company enrichment API, for example.

By using a cookie banner, you are essentially providing a contract to the end-user informing of the fact that that you will be placing a tracking cookie onto their machine, and that if they wish to use your site, they must agree to this process. Even if you are not in the EU, you still need to do this, if your site is accessible to anyone within the specified realm. This is it's helpful to get a user's IP address and then do IP geolocation via API, so you can determine when to show the banner. This means that, unless you site is explicitly restricted to countries not covered by the GDPR, you must make modifications to your site if you gather any information whatsoever about your users or run the risk of litigation.
There are a number of criteria that are absolutely necessary for a cookie banner to be fully GDPR compliant. While it may be difficult to include all of this information on the banner itself, it is acceptable to have a banner with a link to the full agreement upon which the viewer can click and read the full document. The following are required for full compliance:
