Cookies Policy for Website: What You Need and How to Write One

A cookies policy for website compliance is a dedicated page that tells visitors exactly what cookies your site uses, why it uses them, and how visitors can control or refuse them. Nearly every website sets cookies, and multiple laws around the world require you to be transparent about it.

If you run a website that serves visitors in the EU, UK, California, Brazil, or dozens of other jurisdictions, you need a website cookie policy. This guide explains the legal basis for that requirement, what your policy must contain, and how to create one that actually meets the standard regulators expect. This is educational content and not legal advice. Consult a qualified attorney for guidance specific to your circumstances.

What a Cookies Policy Is and Why Websites Need One

A cookies policy is a legal disclosure document that describes the cookies and similar tracking technologies (such as pixels, local storage, and fingerprinting) that a website uses. It is separate from a privacy policy, though the two documents are related.

The purpose of a website cookies policy is transparency. Before a visitor can make a meaningful choice about whether to accept or reject cookies, they need to understand what cookies exist, what data those cookies collect, who receives that data, and how long the cookies persist.

Three main legal frameworks create the obligation to publish a website cookie policy:

• The ePrivacy Directive (EU): Article 5(3) requires informed consent before placing non-essential cookies. "Informed" means the visitor has access to clear information about each cookie's purpose, which a cookie policy provides.
• The GDPR (EU/UK): Articles 13 and 14 require data controllers to provide specific information about data processing activities. When cookies collect personal data (and most analytics and marketing cookies do), the GDPR's transparency requirements apply.
• The CCPA/CPRA (California): Requires businesses to disclose the categories of personal information collected and the purposes of collection. Cookies that track behavior qualify as collection of personal information under the CCPA.

Other laws, including Brazil's LGPD, South Africa's POPIA, and Canada's PIPEDA, impose similar disclosure requirements. If your website is accessible globally, a comprehensive cookie policy is a practical necessity regardless of where your business is incorporated.

Do You Need a Cookie Policy on Your Website

The short answer is almost certainly yes. The question of whether you need a cookie policy on your website depends on two factors: whether your site uses cookies, and whether your visitors are located in jurisdictions that require cookie disclosures.

Does your website set cookies?

If your website uses any of the following, it sets cookies:

• Google Analytics, Matomo, or any analytics platform
• Google Ads, Facebook Pixel, LinkedIn Insight Tag, or any advertising tool
• YouTube, Vimeo, or other embedded video players
• Social media sharing buttons or embedded feeds
• A content management system such as WordPress, Shopify, or Squarespace
• Contact forms, chat widgets, or customer support tools
• A payment processor
• A/B testing or personalization tools
• Caching or performance optimization plugins

A website with no cookies at all is extremely rare. Even a simple static site often uses a hosting provider that sets performance cookies, or includes a single embedded font that triggers a third-party cookie.

Which laws apply to your website?

The laws apply based on where your visitors are, not where your business is located:

• EU/UK visitors: ePrivacy Directive + GDPR apply. Cookie policy required. Consent required before non-essential cookies.
• California visitors: CCPA/CPRA applies. Disclosure of data collection required. Opt-out rights for sale/sharing of personal information.
• Brazilian visitors: LGPD applies. Transparency about data processing required.
• Canadian visitors: PIPEDA applies. Meaningful consent for data collection required.

If your website is publicly accessible and you have not geo-blocked specific regions, assume these laws apply to you. Regulators have consistently taken the position that a website accessible in their jurisdiction is subject to their law.

What Your Website Cookie Policy Must Include

A cookie policy that satisfies legal requirements must contain specific, concrete information. Vague statements like "we use cookies to improve your experience" are insufficient and have been explicitly criticized by regulators.

Required elements

1. Definition of cookies: A brief, plain-language explanation of what cookies are and how they work. Do not assume visitors have technical knowledge.

2. Categories of cookies used: Group cookies into clear categories with descriptions of each category's purpose:

   • Strictly necessary cookies
   • Analytics and performance cookies
   • Advertising and marketing cookies
   • Functional cookies
   • Social media cookies

3. Cookie table: A detailed table listing each cookie with:

   • Cookie name (e.g., _ga, _fbp, session_id)
   • Provider or domain (first-party vs. third-party)
   • Purpose (what it does in plain language)
   • Type (persistent or session)
   • Duration (how long it persists)

4. Third-party disclosures: Identify every third party that sets cookies through your site, explain what data they receive, and link to their privacy policies.

5. Legal basis for cookies: Under the GDPR, this is typically consent for non-essential cookies (Article 6(1)(a)) and legitimate interest for strictly necessary cookies (Article 6(1)(f)).

6. How to manage cookies: Instructions for:

   • Using your consent banner to accept or reject cookie categories
   • Changing cookie preferences after the initial choice
   • Managing cookies through browser settings
   • Opting out of specific third-party cookies (link to opt-out pages)

7. Contact information: How visitors can reach you with questions about your cookie practices.

8. Last updated date: The date the policy was last reviewed and modified.

Common omissions regulators flag

• Listing cookie categories without naming specific cookies
• Failing to identify third-party cookie providers
• Not explaining how long cookies persist
• Omitting instructions for withdrawing consent
• Using technical jargon without explanation
• Not linking the cookie policy from the consent banner

How to Write a Cookies Policy for Your Website

Writing a website cookies policy requires starting with an accurate inventory of your cookies, then drafting the document to cover all required elements.

Step 1: Audit your cookies

You cannot write an accurate cookie policy without knowing exactly what cookies your website sets. Manually checking is unreliable because cookies vary by page, user state, and third-party script behavior.

Run an automated scan of your website that crawls every page and records every cookie, pixel, and local storage entry. The scan should identify:

• Cookie name and value pattern
• The domain that sets the cookie
• Whether it is a session cookie or persistent cookie
• The expiration time for persistent cookies
• The page or script that triggers the cookie

Repeat this scan regularly. Every plugin update, new integration, or theme change can introduce new cookies that your policy must disclose.

Step 2: Categorize your cookies

Map each cookie from your audit to one of the standard categories: strictly necessary, analytics, marketing, functional, or social media. Be conservative in your categorization. If a cookie could reasonably fall into "marketing" rather than "functional," categorize it as marketing, because that is the higher-consent category.

Step 3: Draft the policy

Structure your policy in the order listed in the "What Your Website Cookie Policy Must Include" section above. Use plain language throughout. If you need to use a technical term, define it immediately.

A cookie policy generator can produce a structured policy that covers the required elements and formats the cookie table correctly. You will still need to review and customize the output to match your specific cookie inventory.

Step 4: Link the policy

Your cookie policy must be accessible from at least two places:

• Your consent banner: Include a direct link so visitors can read the full policy before making their consent choice
• Your website footer: A persistent link alongside your privacy policy generator output and terms of service

If you include cookie information within your privacy policy rather than as a standalone document, make sure the consent banner links directly to the cookie section, not just to the top of the privacy policy.

Step 5: Review and publish

Before publishing, verify the policy against your audit results. Every cookie from the audit should appear in the policy. Every cookie listed in the policy should exist in the audit. Mismatches indicate either an incomplete audit or an inaccurate policy, and both are problems.

Cookies Policy vs. Privacy Policy: Key Differences

A website cookies policy and a privacy policy serve different purposes and cover different ground. Understanding the distinction helps you avoid gaps in your compliance documentation.

Privacy policy scope

A privacy policy covers the full scope of personal data processing by your organization:

• Data collected through forms, account registration, and purchases
• How data is stored, secured, and retained
• Data sharing with third parties and service providers
• Individual rights (access, deletion, correction, portability)
• International data transfers
• Data protection officer contact information
• Legal bases for all processing activities

Cookie policy scope

A website cookie policy focuses narrowly on:

• Cookies and similar technologies used on the website
• Specific cookie names, purposes, and durations
• Third-party cookies and their providers
• How to control cookies through the consent banner and browser settings

How they work together

Some businesses combine both documents into a single privacy policy with a dedicated cookies section. This is legally permissible, but separate documents have advantages:

• A standalone cookie policy is easier to link from the consent banner
• Updates to cookies (which happen frequently with plugin changes) do not require republishing the entire privacy policy
• Visitors looking for cookie-specific information can find it faster
• Regulatory auditors can assess cookie compliance more easily with a dedicated document

The EDPB has not mandated a standalone cookie policy, but the trend in enforcement is toward detailed, specific cookie disclosures that standalone documents deliver more effectively.

Keeping Your Website Cookies Policy Up to Date

A cookie policy is not a one-time document. Websites change constantly, and every change can affect your cookie inventory. An outdated policy is almost as problematic as having no policy at all, because it fails the transparency requirement.

When to update your cookie policy

Update your website cookies policy when any of the following occurs:

• You install or remove a plugin, extension, or integration
• You change analytics providers (e.g., switching from Google Analytics to Matomo)
• You add advertising or retargeting tools
• You embed new third-party content (videos, maps, social feeds)
• You update a plugin and the update changes its cookie behavior
• A third-party provider changes its cookies (Google and Facebook do this regularly)
• You expand into new jurisdictions with different legal requirements
• Cookie consent laws change (such as the transition from ePrivacy Directive to the upcoming ePrivacy Regulation)

Establishing a review cadence

At minimum, scan your website quarterly and compare the results against your published cookie policy. This cadence catches changes introduced by plugin updates and third-party script modifications that you may not have noticed.

For high-traffic or complex sites, monthly scans are more appropriate. The cost of scanning is minimal compared to the regulatory exposure of an inaccurate policy.

Communicating changes

When you make material changes to your cookie policy, consider these steps:

1. Update the "last updated" date at the top of the policy
2. Reset consent for existing visitors if new cookie categories have been added, so they can make an informed choice about the new cookies
3. If the changes are significant (new third-party data sharing, new tracking categories), consider displaying a notification to returning visitors

Cookie Policy Requirements by Jurisdiction

While the core principle is the same everywhere, transparency about tracking, the specific requirements vary by jurisdiction. If your website serves a global audience, your cookies policy should meet the most stringent standard.

European Union and UK

The ePrivacy Directive and GDPR set the highest bar globally:

• Prior, informed consent required before non-essential cookies (Article 5(3) ePrivacy Directive)
• Detailed information about each cookie (GDPR Articles 13 and 14)
• Ability to withdraw consent as easily as it was given (GDPR Article 7(3))
• Records of consent must be maintained
• Fines up to 20 million EUR or 4% of annual global turnover

California (CCPA/CPRA)

• Disclosure of categories of personal information collected, which includes data from cookies
• "Do Not Sell or Share My Personal Information" link required if cookies are used for cross-context behavioral advertising
• Right to opt out of sale or sharing
• Fines of $2,500 per unintentional violation, $7,500 per intentional violation

Brazil (LGPD)

• Consent required for personal data processing, including via cookies
• Purpose limitation: cookies must serve a specific, disclosed purpose
• Transparency about data processing activities

Canada (PIPEDA)

• Meaningful consent required for collection of personal information
• Organizations must explain purposes in a way individuals can reasonably understand
• Consent may be implied for less sensitive data in some contexts, but cookie disclosures are still required

Frequently Asked Questions

Do I need a cookie policy on my website?

Yes, if your website uses cookies, which nearly all websites do. The ePrivacy Directive (Article 5(3)) and the GDPR (Articles 13 and 14) require you to inform visitors about what cookies you use, their purposes, and how visitors can control them. This applies to any website that serves visitors in the EU or UK, regardless of where the business is based. Even outside the EU, laws such as the CCPA, LGPD, and POPIA require disclosure of tracking technologies.

Is a cookie policy the same as a privacy policy?

No. A privacy policy covers all personal data processing across your organization, including data collected through forms, accounts, purchases, and customer support. A cookie policy focuses specifically on cookies and similar tracking technologies used on your website. While some businesses include cookie disclosures within their privacy policy, a standalone cookie policy provides the detail and clarity that regulators expect, particularly the specific cookie table listing names, purposes, providers, and durations.

What happens if my website does not have a cookie policy?

Operating a website without a cookie policy when you use non-essential cookies violates the transparency requirements of the GDPR (Articles 13 and 14) and the ePrivacy Directive (Article 5(3)). GDPR fines can reach up to 20 million EUR or 4% of annual global turnover. The CCPA imposes penalties of $2,500 per unintentional violation and $7,500 per intentional violation. Beyond fines, missing policies can lead to complaints from visitors, negative publicity, and orders from regulators to cease processing.

How often should I update my website cookie policy?

You should review and update your cookie policy whenever you add or remove plugins, change analytics providers, integrate new third-party services, or modify how you use visitor data. At minimum, conduct a quarterly review by scanning your site for cookies and comparing the results against your published policy. Any discrepancy means your policy needs updating. Major changes should be communicated to visitors through your consent banner.
