Did you know that website user privacy is no longer optional or a business preference? It is, in fact, a legal requirement and a critical part of maintaining digital performance.
\nIn addition to the GDPR reformations in 2018, since the 2024 rollout of Google Consent Mode v2, which stated that if you are wanting to use audience data for remarketing or other Google advertising services in the UK and in the EU, implementing consent mode is now required.
\nIf your website still relies on a basic cookie banner, or no consent mechanism at all, here’s what you need to know.
\n2024 saw a major shift toward privacy-first marketing. With the introduction of Google Consent Mode v2, businesses are required to send consent signals to continue using Google Ads effectively. Two years on, enforcement has intensified.
\nRegulators, browsers and advertising platforms now expect websites to:
\nCollect clear, informed user consent
\nPrevent tracking before consent is given
\nStore and manage consent records
\nSend accurate consent signals to platforms like Google Ads
\nWithout a Cookie Management System in place, achieving this is almost impossible. Here we take a look at the dangers of not having a CMS:
\nBy far one of the biggest and most immediate implications for a business is financial. Under GDPR (General Data Protection Regulation which gives individuals greater control over their personal data), fines can reach up to €20 million or 4% of global annual turnover.
\nFurthermore in the UK, PECR (Privacy and Electronic Communications Regulations) which sits alongside GDPR and governs marketing calls, emails, texts and cookies regulations, has also been strengthened. Penalties now reach up to £17.5 million or 4% of annual revenue.
\nHow enforcement works is also changing. Regulators are able to use automated scanning tools to detect websites that don’t comply. This means that a site no longer needs to be reported, it can be flagged automatically.
\nIf your business relies on platforms like Google Ads, without cookies consent, numerous problems arise. Consent signals may not be passed correctly, tracking may be disabled entirely and conversion data becomes incomplete or inaccurate. All of these things directly impact campaign performance.
\nWith Google Consent Mode v2, if a user does not consent, Google can only use cookieless pings (limited and non-identifiable data). While somewhat helpful, it’s not a replacement for comprehensive tracking.
\nWorse still, failure to comply with consent policies can result in loss of remarketing capabilities, reduced audience targeting, as well as potential ad account suspension. Without this data, a business is unable to effectively manage their Google advertising efforts or budget.
\nUsers are ever more aware of privacy, and a poor or misleading cookie notice can deter users. A confusing or unclear design is also offputting, as are cookies firing before consent is given. If users feel they’re being tracked without their permission, they’re more likely to leave a site. Therefore a business may not only lose potential custom, the site will also see increasing bounce rates and reducing conversions.
\nTo avoid all of the risks, a business should ensure that their website:
\nUses a Cookie Management Platform
\nRecords and stores user consent
\nRegularly scans the site for active cookies
\nWhen running ads: Implements and correctly configures Google Consent Mode v2
\nNot having a Cookie Management System in 2026 can no longer be seen as an oversight, it’s a serious business requirement.
\nFrom legal penalties to lost advertising performance and damaged user trust, the consequences can be significant. The good news is that implementing a compliant CMS not only protects your business but also helps contribute to effective, data-driven marketing.
