Version control

Website and technology

Version control means every change in a project is recorded, so you can see what changed and roll back to an earlier version.

The best-known example is Git for code, usually via GitHub. The same principle sits in a CMS that keeps page revisions, in Google Docs, and in ad platforms that keep a change log. It always comes down to three things: what changed, by whom, and can it be undone.

Why that matters: mistakes are inevitable. If a change can be reverted in one step, a mistake is a brief interruption rather than a problem. Version control also lets people collaborate without overwriting each other's work, and leaves a log for when you later ask why something is the way it is.

For marketing the translation is practical: record when you change a page, campaign or tracking setup. When the numbers move afterwards, you can tie that to a moment instead of guessing.

Tip

Record changes to campaigns, copy and tracking too, not just your code. That way you can always tie shifts in your numbers to a specific moment.
