Squarespace install guide

Add Velo to Squarespace.

Install the Velo cookie banner and Google Consent Mode v2 on Squarespace in minutes. One line in the Header injection field does it. If you already run Google Tag Manager, that route is on this page too.

Paste one line
into the Header field.

One line in Squarespace, and the banner is on every page with the Consent Mode default set before any other tag can fire. Same banner, same wiring and the same audit log as the Tag Manager route.

Already running Google Tag Manager? Take that route instead ↓

Three steps · about two minutes

  1. 01

    Copy the line

    One script tag, the same on every page of the site. Everything below is about getting it into the right place, and that place is always the head, ahead of the tags it governs.

    <!-- Before your other tags. That order is the point. --> <script src="https://veloconsent.com/v1/velo.js" data-velo-site="your-site-id" defer></script>
  2. 02

    Open Code injection

    Go to Settings → Developer tools → Code injection and paste the snippet into the Header field, then save. Code injection is available on the Business plan and above.

    Reload the site

    The banner renders on the next page load, on every page of the site, with the Consent Mode default set before any other tag can fire. Version 7.0 and 7.1 sites both work the same way.

One thing to watch

Switch Squarespace's own banner off under Cookies & Visitor Data so Velo is the only layer your visitors see. The Header injection applies site wide, so there is nothing to add per page — and 7.0 and 7.1 sites both work the same way.

Recommended if you run a container

Or import the tag
in Tag Manager.

One tag, no code on the page, and your whole measurement stack stays in one place. No Tag Manager yet? Paste the GTM container into the same Header field under Code injection, save, then start here.

Squarespace questions,
answered.

What teams installing on Squarespace ask first.

Which Squarespace plan do I need?

Code injection requires the Business plan or higher, the same requirement any custom tag on Squarespace has. From there, either method on this page takes a couple of minutes.

Squarespace has its own cookie banner setting.

Switch it off under Cookies & Visitor Data so Velo is the only banner your visitors see. Two banners confuse people, and two consent layers send Google conflicting signals.

Do I need to add it per page?

No. The Header injection applies site wide: every page, blog post and product page inherits it. Per page injection exists on Squarespace but is not needed for Velo.

Will it slow the site down?

No. The script loads deferred, never blocks rendering, and the visitor's region is resolved at the nearest edge before the page finishes painting. The banner itself is a few kilobytes of static code.

Can an AI assistant do this for me?

Yes. Copy the prompt in Install with agents, just below, into Claude, ChatGPT, Cursor or whichever assistant you already use. It carries the steps on this page, the order the tags have to load in, and the checks the agent has to run before it tells you the job is done.

Or hand it
to an agent.

Copy the prompt into Claude, ChatGPT, Cursor or whichever assistant you already use. It carries everything on this page: both routes, the order the tags have to load in, and the checks that prove it worked.

The prompt

Paste it in as your first message, then swap your-site-id for the ID on your Velo dashboard. Everything else the agent needs is already written into it, including what to check before publishing.

Install prompt · Squarespace
# Install Velo on Squarespace: cookie banner + Google Consent Mode v2 You are installing Velo, a consent management platform, on my Squarespace site. Velo shows the cookie banner, sets the Google Consent Mode v2 defaults before any other tag can fire, and records every decision. Ask me for these before you touch anything: - My Velo site id. It is in the Velo dashboard. No account yet? Send me to https://veloconsent.com/get-started and wait for the id. - Whether the site already runs Google Tag Manager, and which container. - Which cookie banner or consent tool is live on the site today. ## Path A: through Google Tag Manager (preferred when GTM is live) 1. Templates → Tag Templates → New, then ⋮ → Import. Import the template.tpl from github.com/ampliodata/velo-cmp ("Velo CMP"). 2. Create a tag from that template. Set my Velo site id and pick the light or dark theme. 3. Fire it on the "Consent Initialization – All Pages" trigger. Not Initialization, not All Pages. Both run too late to set consent defaults. 4. Preview, check the Consent tab in Tag Assistant, then Submit and Publish. No container yet? On Squarespace, paste the container snippet into Settings → Developer tools → Code injection (Header) and the noscript tag into Footer. That needs a Business plan or higher. ## Path B: the snippet, straight into the site Put this line in the <head>, above every analytics and advertising tag: <script src="https://veloconsent.com/v1/velo.js" data-velo-site="MY_SITE_ID" defer></script> On Squarespace: Settings → Developer tools → Code injection → the Header field → Save. Code injection is available on the Business plan and above. ## Rules - One path, never both. Two installs means two banners. - Velo loads first. Everything that measures or advertises comes after. - Only one tool may set Consent Mode defaults. Switch off the Squarespace cookie banner under Cookies & Visitor Data so Velo is the only banner running. Leave no hard coded gtag('consent', 'default', ...) anywhere else either. - Change nothing beyond what this install needs. Tell me first if a theme file, plugin or existing tag has to be touched. ## Verify, then report back - The banner renders on a fresh load in a private window. - Before I choose, every consent signal except security_storage is denied from an EEA, UK or Swiss location. - Accepting and rejecting each flip the matching signals, and a velo_consent_update event lands in the data layer. - Google tags stay in their cookieless mode until consent is granted, and any tag gated by hand fires only after it. - window.Velo is defined, and Velo.open() reopens the preferences panel. - On a Tag Manager install, Tag Assistant shows the Velo tag firing on Consent Initialization ahead of every other tag. Tell me what you changed, where you changed it, and what each check showed. If a check fails, fix it and run the checks again.
