Implementation checklist

Work through this list before a campaign goes live on real traffic. Each item links to the page that explains it. Most problems it catches are silent: the page loads, but visitors see the original or are not counted.

Snippet

• The snippet is at the top of <head>, above every other script, on every page template where campaigns run or goals are measured. See Install the Grona script.
• Both YOUR_WORKSPACE_ID placeholders are replaced with your workspace id.
• There is exactly one copy per page, loaded from cdn.grona.ai, not bundled or self-hosted.
• The anti-flicker script has no async or defer, and data-grona-af-bg matches your page background. See Prevent flicker.
• Cache and optimisation plugins exclude both Grona scripts from delaying, combining and minifying.
• The snippet is not added through a tag manager, or you accept the flicker that causes. See Google Tag Manager.

Verification

• The dashboard check shows “Verified Successfully!”, or the API check returns present, for each page you target. See Verify your installation.
• In a normal browser, antiflicker.js and main.js load without errors, and a preview link shows the variation. See Preview and QA a variation.

Security and privacy

• Your Content-Security-Policy allows cdn.grona.ai in script-src, connect-src and img-src, api.grona.ai in connect-src, and 'unsafe-inline' in style-src. See Content Security Policy.
• You have chosen a consent mode, and your privacy notice covers the storage keys Grona writes. See Consent and storage.
• If you use Wait for consent, your consent tool is one Grona reads, or it sends a Google Consent Mode update. See Consent platforms.

Your site

• All traffic reaches one canonical host and scheme (for example https://shop.example.com), so each visitor keeps one id. See Domains and subdomains.
• If your site is a single-page app, it routes with the History API, not # fragments, and the elements you change are not redrawn after load. See Single-page applications and Server rendering and hydration.
• The pages you edit are reachable from the public internet without a login, so the visual editor can open them. See Visual editor requirements.
• If a campaign uses page-variable targeting, the page variable is set as a string in an inline script above the snippet. See Target visitors by page variable.

Measurement

• Goals are set up and fire on the right pages. See Track conversions and custom events.
• You measure page speed with real-user monitoring, not Lighthouse or PageSpeed Insights, which Grona treats as bots. See Performance.
• Your visitors’ browsers are supported. See Supported browsers.
