when to set up 2 Shopping campaign for the same products
Re: when to set up 2 Shopping campaign for the same products
the original, primary, use-case for campaign priorities was to help
with a smooth transition from regular-product-listing-ads to the
new shopping-campaigns for product-listing-ads -- by allowing the
new campaign to be created and configured while not interfering
or competing with the legacy campaign -- i.e. a staging area.
the staging-area concept remains the primary use-case for priorities.
generally, the same product should never be within multiple campaigns
or multiple product-groups, to avoid self-competition and other issues --
however, a separate campaign with a lower priority allows for the staging
and swapping of a new campaign-strategy, for a specific set of products,
without triggering self-competition and related issues.
priority-based campaigns typically (must) also include a filter.
for example, for an upcoming sales event for a subset of products.
