Do You Need to Code a Cookie Banner?
Not usually. A cookie banner looks like a small bar at the bottom of the screen, but a compliant one is doing a lot of work behind the scenes. For most websites, a consent management platform is faster to launch and easier to maintain than custom code. To meet laws like the GDPR and the UK's PECR, your banner has to:
- Notify visitors that your site uses cookies, in plain language.
- Block non-essential trackers (analytics, marketing, advertising) until the visitor gives consent — not after.
- Make rejecting as easy as accepting, with a clear "Reject All" option.
- Log every choice so you have proof of consent if a regulator asks.
- Let users change their mind and withdraw consent at any time.
Hand-coding all of that means writing consent logic, intercepting scripts before they fire, building a preferences modal, and storing a consent record — then maintaining it as the law changes. For the full breakdown of what regulators expect, see our guide to GDPR cookie consent requirements.
The good news: a tool can do every one of these steps for you, and most of them are free.
What Is a Consent Management Platform (CMP)?
A Consent Management Platform (CMP) is the standard, no-code way to add a cookie banner. It handles the entire consent lifecycle:
- Scan — automatically crawls your website and detects every cookie and tracking technology in use.
- Block — prevents non-essential scripts from running until the visitor consents.
- Ask — shows the consent banner and a preferences panel where visitors choose cookie categories.
- Log — records each consent choice with a timestamp as proof of compliance.
Instead of building this yourself, you configure it once and paste a single snippet into your site. That's it — the CMP keeps working on every page.
Not sure what's running on your site? Run a free cookie scan to see every cookie and tracker before you set up your banner.
Option 1 (Recommended): Use a Free Banner Generator
The simplest path is our own free cookie banner generator. It's GDPR, PECR, CCPA, and Law 25 ready, requires no credit card, and installs with a single copy-and-paste. Here's the whole process:
- Build your banner. Open the visual banner builder, pick your colours and text, and choose which cookie categories to offer (necessary, analytics, marketing).
- Create your free account to get the snippet. When you're happy with the preview, sign up to save the banner and unlock the short
<script>install code. - Paste it into your site's header. Add the snippet to the
<head>section of your site (platform-specific steps are below). The banner appears immediately and starts blocking non-essential cookies until visitors consent. - Scan and confirm. Run a cookie scan so every tracker is categorised correctly, then publish.

Other CMP Options
If you're comparing tools, here are three well-known alternatives. Each is a capable CMP — the right choice depends on your platform and budget:
- Cookiebot — strong automatic cookie scanning and easy integration with Google Tag Manager. Good for larger sites that want detailed scan reports.
- iubenda — an all-in-one compliance suite (cookie banner, privacy policy, terms) that's especially popular with WordPress users.
- TermsFeed — a straightforward free cookie consent banner generator, useful for simple static sites.
All of them follow the same install pattern: build the banner in their dashboard, then paste the provided snippet into your site header — exactly like the steps above.
How to Add a Cookie Banner by Platform
Once you have your snippet, here's where it goes on the most common platforms.
WordPress
You have two options:
- Plugin (easiest): Search the Plugins → Add New directory for a cookie consent plugin, install and activate it, then connect or paste your CMP snippet in its settings.
- Manual snippet: Paste the snippet into your site header using a header-scripts plugin (e.g. "Insert Headers and Footers"), your theme's Customize → Header option, or the
header.phpfile in a child theme.
After installing, run a cookie scan and confirm your categories. See our WordPress-friendly compliance steps for more detail.
Shopify
- App (easiest): Install a cookie consent app from the Shopify App Store and follow its setup wizard.
- Manual snippet: Go to Online Store → Themes → Edit code, open
theme.liquid, and paste your snippet just before the closing</head>tag.
Shopify also has a built-in customer privacy banner you can enable in Settings → Customer privacy for basic coverage.
Webflow
- Open Project Settings → Custom Code, paste your snippet into the Head Code field, then Save and Publish.
- For a single page only, use Page Settings → Custom Code instead.
Webflow also offers a native cookie consent feature under Project Settings → Privacy for simple banners.
Any HTML / other CMS
Paste the snippet immediately before the closing </head> tag in your site template. Loading it in the <head> matters — it lets the banner block trackers before they fire, which is what compliance requires.
Google Consent Mode v2 and Tag Manager
If you run Google Analytics or Google Ads, you'll need Consent Mode v2. Since March 2024, Google requires it so that ad and measurement features keep working for visitors in the EEA and UK — and it only sends data once a user consents.
A good CMP integrates with Consent Mode v2 automatically: when a visitor accepts or rejects, the banner updates Google's consent signals for you. If you manage tags through Google Tag Manager, follow our dedicated Google Tag Manager cookie consent guide to wire it up correctly.
Conclusion
Adding a cookie banner is no longer a coding project — it's a paste-one-snippet task.
Key Takeaways:
- You don't need to build a banner from scratch; a CMP handles scanning, blocking, asking, and logging.
- A compliant banner must block non-essential cookies until consent, make rejecting easy, allow withdrawal, and keep a consent log.
- Installation is the same everywhere: build the banner, create your free account to get the snippet, then paste it into your
<head>. - If you use Google Analytics or Ads, enable Consent Mode v2.
Next Steps:
- Scan your site to see which cookies you're actually using.
- Build your free cookie banner, then create your account to get the snippet.
- Paste the snippet into your platform's header and publish.

Frequently Asked Questions
What is a cookie banner?
Answer: A cookie banner is the notice that appears when someone visits your website, asking permission before non-essential cookies (analytics, marketing, advertising) are set. Under laws like GDPR and PECR it must let visitors accept, reject, or customise their choices, block tracking until consent is given, and record what they chose.
Do I need to code a cookie banner myself?
Answer: No. Coding a compliant banner from scratch means writing consent logic, blocking scripts before consent, building a preferences modal, and storing a consent log. A consent management platform (CMP) lets you build the banner visually, then create an account to save it and get the install snippet.
What is a Consent Management Platform (CMP)?
Answer: A Consent Management Platform (CMP) is a tool that automatically scans your website for cookies and trackers, blocks non-essential ones until the visitor consents, shows a consent banner and preferences panel, and logs every choice as proof of consent. It is the standard, no-code way to add a compliant cookie banner.
How do I add a cookie banner to WordPress?
Answer: The easiest way is to install a cookie consent plugin from the WordPress Plugin Directory and activate it, or paste your CMP's snippet into the site header. You can add the snippet via your theme's header settings, a header-scripts plugin, or by editing header.php in your theme. After installing, run a cookie scan and configure your cookie categories.
How do I add a cookie banner to Shopify?
Answer: Install a cookie consent app from the Shopify App Store, or paste your CMP snippet into your theme. To add it manually, go to Online Store > Themes > Edit code, open theme.liquid, and paste the snippet just before the closing head tag. Shopify also offers a built-in customer privacy banner you can enable in store settings.
How do I add a cookie banner to Webflow?
Answer: In Webflow, open Project Settings > Custom Code and paste your CMP snippet into the Head Code field, then save and publish your site. For a single page, you can instead use Page Settings > Custom Code. Webflow also has a native cookie consent feature under Project Settings > Privacy you can use for basic banners.
Do I need a cookie banner if I only use Google Analytics?
Answer: Yes. Google Analytics sets cookies and collects personal data such as IP addresses and online identifiers, which require consent under GDPR and PECR. You must obtain consent before Analytics loads, and from March 2024 Google requires Consent Mode v2 to keep ad and measurement features working for EEA and UK users.
Is a free cookie banner GDPR compliant?
Answer: It can be, as long as it does the four things the law requires: blocks non-essential cookies until consent, makes rejecting as easy as accepting, lets visitors withdraw consent later, and keeps a record of consent. Avoid free banners that only display a notice but still load trackers automatically, as those are not compliant.
How long does it take to add a cookie banner?
Answer: With a consent management platform, most websites can add a fully working cookie banner in about 5 minutes: build the banner, create a free account to get the snippet, and paste it into your site header. Auto-scanning and categorising your cookies adds a few more minutes but is handled by the tool.
