As mentioned above, the landing page should be as relevant as possible to the search query and ad.
If you provide several services that are different from each other, divide them into different landing pages and fill each of them with content.
For an online store, you need to choose the page most relevant to the search query.
If this is a product code or other query that only one specific product matches, then you should advertise on the product card.
If several products match the query, we direct traffic to the catalog, search, or filtering page.
For example, a request to buy a laptop should take the user to a page that lists all laptops. A poland rcs data request to buy an Asus laptop should take the user to a page that lists only ASUS laptops. You need to think about the request for iPhone XS 128 Gb , because it may be matched by several models with different colors or in different conditions. You can drive traffic to the product card, if there is an option to choose a color, or to the search or filtering page.
A common mistake that often occurs is to add general queries to your ads, direct them to the catalog, and not add product codes to your negative keywords. In this case, you can buy clicks on search phrases that contain product codes and should lead to a specific product page, but instead the user ends up in the catalog, where they most likely won't see the product they need and will go to another site.
