Part one covered the fleet the web grew up with — search, direct, referral and social. This page covers the vehicles that matter most to a publisher building the next decade: the ones you can own, rent carefully, or be cited by.
Email: the vehicle you own
Every other channel rents its audience from a landlord who can change the lease overnight. Email is the exception: the list is property, the delivery protocol is open, and the algorithm deciding who sees what is a spam filter you can actually study. The physics are different too — email is push, so traffic arrives on your schedule rather than the crawler’s. The craft questions are cadence (weekly beats monthly for journals), density (one idea per send), and the archive strategy that turns old issues into searchable assets. Cost of scale is sending infrastructure and list hygiene, both linear and cheap until you are very large indeed.
Communities: the vehicle with a door policy
Forums, Slack and Discord servers, subreddits, niche Discourses: the places where the people who care about your subject already gather. Community traffic is the highest-intent traffic on this page and the easiest to lose, because communities smell extraction at a distance. The working method is the campsite rule: answer questions completely, share knowledge with no link attached, and let your profile — not your post — carry the address. When you do link, link to the page that answers the thread’s exact question. One durable reputation inside one community outperforms a hundred drive-by drops.
Aggregators and curators: the borrowed spotlight
Link round-ups, industry newsletters, “what we’re reading” sections, Hacker News and its cousins. Curators are intermediaries between you and audiences they spent years assembling, and being picked is mostly a function of being pickable: original data, clear structure, a headline that promises specifically. The economics mirror referral — a spike, then decay — so the professional move is to convert the spotlight: a visiting curator’s audience should find an obvious subscribe invitation waiting. Track which curators pick you repeatedly; that shortlist is a distribution channel in embryo.
AI assistants: the citation vehicle
When a generated answer cites three sources, it has effectively chosen three blue links out of the whole index. The selection criteria observable so far favour exactly what search claimed to favour: genuine expertise, clear structure, quotable specifics, and pages that answer one question completely rather than ten questions thinly. Our field notes on AI Overviews cover the tactics; the strategic point belongs here: the AI vehicle rewards the same asset quality as referral, which means investment in citable work pays across three channels at once — search, curators, and machines.
Where each one breaks
- Email breaks via list rot — a stale list costs deliverability for everyone on it.
- Communities break via extraction — one promotional cycle too many and the door closes.
- Aggregators break via dependence — a site that lives on round-up spikes has no base of its own.
- AI citations break via measurement — if you cannot see them, you will under-invest in them.
Own the list, earn the communities, court the curators, and be quotable enough that the machines find you.
One closing observation on the fleet as a whole: the newer vehicles reward the same underlying asset as the older ones — work worth the visitor’s time — but they differ sharply in how quickly they forgive absence. Search forgets a dormant site slowly; communities forget within a week; an email list forgets in two missed cadences. Plan presence accordingly: the compounding channels can carry the publishing rhythm while the high-touch ones are fed by it, which is the balance struck in our field note on the weekly rhythm.
The blended strategy follows naturally: build for search and AI citation, distribute through curators and communities, and bank every reader into email. For the costs side of that portfolio, see what web traffic costs; for the weekly schedule that operates it, traffic-building activities.
