Run next to GA4 for a week before you rip anything out

Do not delete GA4 on day one. Add Cookie Free Analytics next to it. A week later you will know what the banner was hiding. That is the migration. The longer recipe is on /migrate.

We count the landing, the source, and the named goal. Ads platforms still do conversion tags. Many sites run both. We will not invent a lift percentage. Your two totals, same date range, are the number.

What will not come across

There is no historical import. Different instruments. Start a clean Cookie Free Analytics history. Hobby shows a badge; Starter hides it from €4. First-party is a c. CNAME.

Compare pageviews to pageviews. A “visitor” here is unique for one UTC day, not a person across a month. Bounce is a 30-minute visit with one page. If you need Google Ads audiences, keep GA.
