Should ads point to product pages or collections?
Match the search. Specific query, specific product page.
The short answer
Match the search. Specific query, specific product page.
If someone searched for a named product, sending them to a collection makes them work for it and costs you conversions. If they searched a category, a well-built collection page can outperform any single product.
Shopping decides this for you by sending traffic to the product page, which is another reason product page quality matters so much.
