Plenty of people can run a sale on a website. Fewer can tell you whether that sale made money once returns, discounts and shipping came out. Learn the platform first, the numbers second, and the trade-offs between channels last, because that's roughly the order hiring managers test them in.
| Certificate | Best for | Effort | Worth it? |
|---|---|---|---|
| Google Analytics Certification | Anyone whose weak spot is reading funnel and checkout data | a few evenings through Skillshop | Free and fast. It helps early on, but a store you've actually tracked matters more in interviews. |
| Amazon Ads Sponsored Ads Certification | Managers at brands that sell on Amazon as well as their own site | a weekend in the Amazon Ads learning console | Worth it if marketplaces are in the job description. Skip it if the role is direct to consumer only. |
Certificate names and exam formats change, so check the provider's own site before you start studying.

Yes, a little of it. Plenty of brands sell in both places, and knowing how Amazon pricing pulls on your own site makes you useful in more rooms.
