I went through 500+ marketing articles and kept the 200 that actually teach you something. Here's the full list by channel.

I've mass-bookmarked every marketing resource I came across for the past 3 years. Blog posts, YouTube deep-dives, Reddit threads, free tools — 500+ links.

Last month I finally organised them. Killed the dead links, removed the thinly-disguised sales pages, and kept only the ones where I actually learned something actionable.

500+ became ~200. I sorted them into 9 channels with learning paths.

I turned all of this into a free interactive mind-map where you can click into each channel → topics → sub-topics → resources:

I also turned it into a free interactive roadmap you can click through (link at bottom) — however here's the full text version:

You can also use Google Boolean search to find high-engagement LinkedIn posts in any niche — search site:linkedin.com/posts + your keyword + engagement words like "agree" or "great point." Each post with 100+ reactions is a pre-built
warm lead list.
LinkedIn group members can message each other for free without being connected and without InMail credits. Most people don't know this. Join 5-10 groups where your ICP hangs out, scan the member list, filter by title, and message with
shared-group context. Response rates run 15-25%.
For follow-ups: 80% of deals require 5+ touches but 44% of people stop after 1. Automate the sequence with personalization variables and reply detection so you never accidentally message someone who already responded.
Export everything to CSV (name, company, LinkedIn URL) and pipe it into your cold email tool for multi-channel outreach. LinkedIn gives you targeting precision, email gives you volume. Together they get 287% higher response than
single-channel.
