Agency services are the named offerings, such as WordPress development or technical SEO, that an agency selects from Upwork's service list to display on its profile, telling clients what kinds of work it will take on.
Alongside its overview and skills, an agency profile carries a services section. Upwork maintains a structured list of services under each category, and the owner or an admin picks the ones the agency offers; the chosen services appear on the public page and feed Upwork's search, so a client looking for an online store build can find agencies that have listed it even if those words are not in the overview. Services sit between the broad directory category an agency lists under and the fine-grained skill tags: a category says web development, a service says e-commerce website development, a skill names the platform.
The list is a declaration of scope, and there is no cost to listing many. Agencies that list every service under their category are telling clients less than agencies that list five, and the better signal is how the services line up with the completed jobs on the profile. A service with no corresponding work in the history is an offer, not a track record.
Services should not be confused with Project Catalog listings, which are fixed-price packages with a set price and delivery time that a client can buy without a proposal. A service on an agency profile is a heading; a catalog project is a product.
How Upwork Insights uses it
Upwork Insights reads the services list from each of the 28,921 agency pages it indexes at observation time, together with its skills, as the methodology lists. They are stored, not scored: the Index Score uses earnings, Job Success Score, badges, momentum and team size only, so an agency gains nothing in the ranking by listing more services.
