A/B test ads for two different pen names

I'm an author. I'm trying to choose between two different pen names. I have registered a domain for each pen name.

I want to run an A/B test ad on Google to see which pen name would get more clicks, all other things being equal. Two versions of an ad for a book will run, differing only in pen names. Ideally, when viewers click through, they will be presented with a "coming soon" landing page with a form they can enter an email address for follow up.

After a week or so, I'd like to see which of the two ads drew the most clicks.

You will set up the ad in my Google ad account, enable analytics and create the landing page. I'll supply ad copy and a background photo for the landing page.

Here's one way to do it, though there may be a simpler way in Google ads: https://hover.blog/a-b-test-domain-name/
