TL;DR
Send 15–20 personalized connection requests per day to your ICP, consistently post original content to grow organic reach, and engage authentically on others' posts. Connection acceptance rates jump from 15% to 35–50% when the request includes a one-line context note about why you're connecting.
LinkedIn connection growth compounds — more connections mean more reach for every post, which generates more followers, which drives more inbound interest.
Connection request strategy:
The cold connection request with no note gets accepted ~15% of the time. A request with a personalized note gets accepted 35–50% of the time. One sentence is enough: "Noticed you're growing the outbound team at Acme — I write about SDR programs a lot and thought we might overlap on some topics." That's it.
Send 15–20 targeted requests per day, staying within LinkedIn's daily limits (which vary but are roughly 100 requests per week for free accounts, more for Sales Navigator).
Content strategy for follower growth:
The followers who haven't connected yet can follow you when your posts show up in their feed via mutual connections. Posting 3–5 times per week on topics your ICP cares about generates follower growth from your second and third-degree network.
High-performing LinkedIn content formats in B2B 2025: - Specific, opinionated takes (not "here are 10 marketing tips") - Short data stories: "We analyzed 500 cold email campaigns. Here's what surprised us." - Contrarian perspectives on common advice - Behind-the-scenes operational insights - Carousel posts/documents on tactical topics
Engagement as a growth lever:
Commenting on posts from people in your ICP community gets you in front of their followers. Aim for 10–15 substantive comments per day on posts from people in your target audience. "Great post!" doesn't count — write 2–3 sentence comments that add a perspective.
The LinkedIn newsletter play: Starting a LinkedIn newsletter automatically notifies your followers and gives you a subscription vehicle outside your post feed.

Keep it under 50 words, reference something specific to them (a post, a company announcement, a mutual connection), ask one clear question, and never pitch in the first message. The connection request note or first message that pitches immediately gets ignored or blocked.
How much does LinkedIn advertising cost?
LinkedIn ads cost $8–20+ per click (CPC) and $30–60 per 1,000 impressions (CPM) — 3–5x more expensive than Meta or Google Display. The minimum daily budget is $10 but you need $300–500/day to generate enough data to optimize. Budget for $5,000–10,000/month to run a meaningful test.
How do I target the right people on LinkedIn?
Use layered targeting: job function + seniority + company size + industry. Avoid over-targeting (audiences below 50,000 have too little reach for statistical significance) and under-targeting (broad audiences waste budget on unqualified impressions). Match the audience size to your budget.
What is a good LinkedIn ad CTR?
A good LinkedIn ad CTR is 0.4–0.8% for Sponsored Content. Anything above 1% is excellent. Below 0.3% signals a creative or audience targeting problem. LinkedIn CTRs are lower than Google Search because you're interrupting people who aren't actively searching — that's expected.
