You should use the terminology that’s recognized by the IP office where you are filing. Each major office maintains a database of accepted descriptions: the USPTO's ID Manual, the EUIPO's TMclass, and IP Australia's goods and services database. Descriptions that match accepted terminology are less likely to trigger a formalities office action.
Other than this, you should try to be specific. Vague descriptions ("general merchandise," "services related to technology") are routinely flagged and returned for clarification. The description should identify precisely what goods are sold or what services are provided; not the business category, but the specific offering.
Avoid claiming goods or services that the brand does not genuinely offer. Overly broad descriptions that stray beyond actual commercial activity create non-use vulnerability after five years and can be challenged in cancellation proceedings.
