Salesforce on a resume: the keyword + the cloud + the version.
Salesforce is the dominant CRM in enterprise US sales, marketing, and customer service postings. ATS parsers match "Salesforce" as a literal, but recruiters look for the specific cloud used — Sales Cloud, Service Cloud, Marketing Cloud, Pardot, Experience Cloud — and the role taken (admin, developer, end user, business analyst).
Both. "Salesforce (Sales Cloud, Service Cloud)" matches the broad ATS string and the specific recruiter Boolean.
Yes — Admin, Advanced Admin, Platform Developer I/II, and the role-specific certs (Sales Cloud Consultant, Service Cloud Consultant) all show up in recruiter Boolean searches.
Mention Salesforce in your tools/skills line as an end user. Don't claim admin work you didn't do — Salesforce admins verify quickly.
Yes for the conceptual skills (CRM hygiene, pipeline reporting, workflow automation). Not for the specific platform commands and certifications. List both if you've used both.
