# How to use the LinkedIn keyword mention signal for buying Last updated 7 November 2026 Finding a vendor through a LinkedIn keyword mention is a direct way to reach the people who sell what you need, and HeyLead can run this search for you. ## What a keyword mention means for a buyer A keyword mention happens when a person writes about a specific topic on LinkedIn. When your campaign goal is to find a vendor, this signal points you to individuals discussing the exact problem you need solved. You are the buyer. Reach the people who sell what you need. Someone writing about the problem you need solved may sell the answer. HeyLead is an AI agent for LinkedIn outreach: it finds the right people, writes to them in the voice of your own LinkedIn posts, follows up, and handles replies. It runs from Claude Code, Cursor, any MCP client or a web dashboard. The message is for the vendor. The fit question HeyLead asks to qualify the profile is: Can this audience sell you this? ## Why this signal matters when you buy People who post about a specific industry challenge often offer a product or service to fix it. Tracking these mentions helps you identify active vendors. HeyLead watches 40+ signal types, scored, matched to your ICP and expiring; a strong signal starts outreach and the opener says why now. It reads your own LinkedIn posts to learn your voice and never posts unless you ask for a post. It runs from the cloud with your laptop closed. ## What to write to a potential vendor When you contact the vendor, the message must be clear. The angle is simple: someone writing about the problem you need solved may sell the answer; say you are buying, then ask. Before an invitation, HeyLead warms up: a profile view, a follow, a comment on a recent post. The sequence includes an invitation with a note, an opening message, up to 2 follow-ups on Free and 5 on Pro, InMail and email fallback. Opening messages, follow-ups and answers to replies wait for your approval until you switch to autopilot; invitations, not-now check-ins and meeting nudges are not held. ## The brief to type into HeyLead You type a one-sentence brief in Claude, Cursor, ChatGPT or the HeyLead dashboard; HeyLead drafts the campaign; you review it and press Launch; nothing is sent before. One sentence creates a draft campaign; nothing is sent until you press Launch. There are six campaign goals: sell a product or service, find a job, hire people, find partners or investors, find a vendor, research interviews. Hire people, find partners or investors and research interviews work with a custom brief. It works in Claude Code, Cursor, Claude Desktop and claude.ai, any MCP client and a web dashboard; in ChatGPT as a custom MCP app (tested on ChatGPT Pro; custom apps depend on your ChatGPT plan and settings). ``` Find a vendor who sells inventory software. Watch for the keyword mention signal. ``` ## Handling replies and limits When a vendor responds to your inquiry, the system manages the conversation. Replies are read, classified and answered from the campaign's facts. A reply that could mean two things gets one short question back. A question your facts can't answer is held for you. "Not now" gets a check-in in 30 days. HubSpot is the CRM it syncs with. Google Calendar is the calendar it books into. Free costs $0 for one connected account with 2 follow-ups. Pro costs $29 a month per connected account. The client's source is on GitHub under MIT; the hosted backend is not. ## Questions people ask ### How much does HeyLead cost?

HeyLead sends from your own LinkedIn account at a human pace: at most 20 invitations a day and 100 a week on a free LinkedIn account (more on Premium or Sales Navigator: a newly connected paid account starts at 20 a day and doubles each week up to its limit), Monday to Friday 08:00 to 22:00 in your time zone, minutes apart. It backs off when LinkedIn pushes back and resumes on its own. You can pause any campaign at any time. HeyLead is not affiliated with LinkedIn.
