Key Features
- T: he feed is not a pure reverse-chronological friend list. It blends 1st-degree connections, follows, company/topic interest, and recommended “out of network” content from the Economic Graph, plus ads. How the Feed ranks content
- R: elevance uses context of the post, profile and network signals, and behavior (read, react, comment, share, dwell). Demographics like age or gender are not used to rank feed visibility (per public help guidance).
- P: latform direction in recent public communications: more LLM/semantic understanding, less inauthentic engagement and engagement-bait / low-quality repetition; favor real expertise and meaningful discussion. Background on feed engineering (blog)
- H: eadline is the most SEO-visible field on your profile—treat it as a title tag. Include primary keyword + value proposition (e.g. “B2B SaaS Marketing | Helping startups scale through content”).
- A: bout section: Write public-facing paragraphs with keywords and proof points. This is indexed and often appears in Google search snippets.
- F: eatured section: Use to showcase key links (site, case studies, press). These appear on your public profile and add backlink value.
