LinkedIn

Definition

LinkedIn is a professional networking platform used for job searching, recruiting, professional branding, and industry networking. Users maintain a profile summarizing their experience and skills, connect with colleagues and peers, and engage with posts and articles to build visibility within their professional community, owned by Microsoft since 2016.

Overview

LinkedIn functions simultaneously as a resume, a network, a job board, and a content platform. A profile includes a headline, summary, work history, education, skills with peer endorsements, and recommendations from colleagues, and it is frequently the first result recruiters and hiring managers see when searching a candidate's name. Recruiters use LinkedIn Recruiter to search by keyword, title, skill, and location, making profile completeness and keyword alignment functionally similar to resume optimization for an ATS. Beyond the static profile, LinkedIn's feed rewards active participation: sharing project updates, commenting on industry posts, and publishing articles can build visibility and inbound opportunities over time, particularly for people building a public professional brand or seeking speaking, consulting, or leadership opportunities. LinkedIn Jobs also lets users apply directly, often via 'Easy Apply,' and see whether they know someone at a company through their network, which is valuable for warm-intro outreach. Networking features include connection requests, direct messaging (InMail for premium accounts), and groups organized around industries or interests. A strong open-to-work signal, thoughtful headline, and quantified experience bullets (similar to resume content) all improve discoverability. LinkedIn also offers Premium tiers with features like who's-viewed-your-profile, salary insights, and LinkedIn Learning courses. Because it's public and searchable, LinkedIn functions as a de facto professional reputation layer — consistency between a LinkedIn profile and a resume is something recruiters commonly check.
