The legal notices of a website: here is a subject that we all tend to avoid dealing with as long as we can, even if it means incurring penalties of which we are not always aware. It’s complex, it’s time-consuming and the regulations in force give the impression of constantly evolving. So, we postpone it. It’s natural… But going head-over-heels in this area is always the wrong choice.

As a digital marketing agency, we are often at the forefront of the difficulties encountered by companies on this subject. We also organized a webinar with Benoît Oberlin (CEO of Sir data) on strategies for maintaining tracking and performance while respecting the legislation on cookies and personal data.

But we realized that before talking about optimizing data collection in compliance with the law, many site owners were not even aware of their obligations in terms of user information. However, this ignorance of the legal rules can have serious consequences, legal, but also reputational.

So, before jumping on a generator of legal notices or copying and pasting the first example of legal notices found on the internet, it may be wise to look at the rules in this area.

In this article, we offer you a quick overview of the question of the legal notices required for a professional website. That said, this article is a simple presentation of the main principles and does not constitute legal advice. The goal is above all to help you situate yourself in relation to your obligations. To go further, it is always advisable to consult a legal professional.

You have been warned! That said, we agree, no online business player has himself consulted this endless list of articles of law to ensure the compliance of the legal notices of his own website…

Possibly, if you are one of the most informed site owners, you may be familiar with the broad outlines of the obligations introduced by the SEO for Psychologist (in particular on the processing of your users’ personal data) and by the “Informatique et Liberates” law. (In particular on the consent to the deposit of cookies on the navigation terminals of your users). If this is not the case, come and discuss it with us, our Account Managers can brief you on the main “privacy” principles to secure your digital marketing:


But, as you can see, the mandatory legal notices are not limited to compliance with these two famous texts.

Risks incurred in the event of non-compliance with the regulations in force

Before moving on to the checklist of legal notices to be included on a professional website, it seemed appropriate to take a detour through the risks incurred in the event of non-compliance with the obligations. Naturally, we think of legal risks, but they are not the only ones…

The simple fact of not displaying the legal notices on a site exposes the owner of this site to a penalty of up to 1 year in prison and a fine of €75,000 for a natural person (€375,000 for a legal person).). In any case, this is the sanction provided for in article 6 of the Law for Confidence in the Digital Economy. Admit that it would be a shame to come to this.

Moreover, the penalties to which sites are exposed that do not comply with the legislation on consent to cookies and the processing of personal data are even greater. If these sanctions were applied at their theoretical level, they could reach 10 to 20 million euros or 4% of the company’s worldwide turnover. Enough to put yourself permanently in the red for not having shown yourself a minimum of conscientiousness.

But that’s not all! Beyond the legal and financial risk, a company that lacks seriousness in its approach to legal notices and other legal obligations related to its website runs the risk of seeing its reputation deteriorate. Consumers are more and more aware of these corporate obligations and they are better able to identify those who are not complying with them. Inevitably, the image they have of these companies suffers and it is today a widespread cause of reduced customer retention.

So, to exercise your activity serenely and continue to build a relationship of trust with your customers, here is the basics of the mandatory legal notices for a website:
