Test up to three designs on the same products

How it works

• Variant A is your main design. Add a design for B, and for C if you want a third.
• Each variant has every feed file at the same address with ?v=b or ?v=c added, for example meta-full.xml?v=b.
• Only the stores that set a variant render it, and a second update on an unchanged feed renders nothing for any variant.

Setting up the test

• Put each variant’s feed into a catalog of its own. The same ids in one catalog would overwrite each other’s images.
• Create one ad set per variant catalog, with the same product set, budget and audience.
• Compare the results in your own Ads Manager and keep the design that wins.

What stays the same

Prices, stock, titles and every other field are identical across variants, and each variant follows the same rules as your main feeds: a changed price sends that product back to its own photo until the new image is ready.
