How to use this report

3 ways to use these figures
  • Price check. BV puts one new followed link from substack.com at $159 (level C), priced on a blend of link types (A 3% · B 2% · C 95%): $80 to an unrelated site (×0.5), $199 to a same-topic site (×1.25). A followed editorial link (level A) would be worth up to $1,193 before relevance. A quote far above $149 for a level C link pays for what BV does not measure. · Backlink value · what this means
  • Qualification and risk. Its Site Strength is 85 / 100; the link it usually gives is mostly level C — usually neutralised (a press-release, syndicated, profile or forum link). · How BV is worked out · what this means
  • Traffic reality check. Set any traffic claim beside the Aug 2026 estimate: 175.9M monthly visits, 18% from organic search (32M). Visits rose 5.2% from Jun 2026 to Aug 2026. Its top keyword by Visits (est.) is “heather cox richardson”, about 46.4K a month; the ad value beside it is the whole market's. · Traffic in detail · what this means

How BV is worked out

Site Strength 85 / 100 · level C · each factor and link type

A followed editorial link from substack.com would be worth up to $1,193 under BV 2.8, before relevance: its Site Strength is 85 out of 100. The link it usually gives is level C, worth about $159 — and relevance to the site it points to moves that between $80 and $199.

Site Strength
85 / 100, in steps of 5 · half the site's authority rating, half its organic traffic on a log scale; 100 is the strongest site on the web. Traffic: 32M estimated monthly organic visits, as of 3 October 2026.

How substack.com links out: the full reading

1 article read · each link counted

Read by mxverify on 3 October 2026: the homepage and 1 article (2 linked from its homepage). This is our own reading of the site, not a vendor's figure, and it is what places a new link on the A–D scale until links placed here are audited.

Thin sample 2 links to other sites across 1 article published in Oct 2026. Strong takes six or more articles and thirty or more links, spread over at least two months where the articles are dated.

Jev, the model that judges every link in a bklink audit, reads these pages as a site whose links are mostly level A — A 93%, B 1.0%, C 5.0%, D 1.0%. Put together with what kind of site it is, how established it is, whether it sells placements and how it links out, a new link here is priced as A 2.9%, B 1.8%, C 95%, D 0.1%.

Jev reads it as a platform where users post (95%), established as a source (42%), and not selling guest, sponsored or paid posts (93%).

Ad value: what a month of the keyword's searches would cost as search ads (searches × cost per click) — what advertisers pay for it, not how hard it is to rank for. Visits (est.): the traffic estimate's own figure for the keyword on this site, which behaves like visits a month, not an amount of money. Each keyword opens the list of sites where it is a top search keyword.

AI assistants

AI assistants sent about 1.3M visits in Aug 2026 — 0.7% of all visits. Each assistant's share of those visits, by month:

Server and network

a CDN edge, shared by unrelated sites

substack.com is served through Cloudflare (CDN), a content delivery network. Its address is shared edge infrastructure used by unrelated sites, so it cannot show who else runs on the same server, and sharing the network is no sign of a connection.

Cloudflare (CDN) fronts millions of unrelated sites, so sharing it says nothing about who runs a site. The count is shown; the sites are not listed.

Limitations: what this report does not show

5 stated plainly
  • No link on this publication has been audited yet, so nothing here describes how its links behave.
  • A CDN address is shared by unrelated sites, so it says nothing about ownership; no neighbours are listed for it.
  • A link that is followed is not necessarily a link search engines value; this record does not measure rankings or traffic.
  • The BV score is what one new followed link from substack.com is worth to rankings, from its Site Strength and the kind of link on offer. It is not a price, and it does not predict what a link will do for a particular site: relevance to that site moves it between half and one and a quarter times.
  • Traffic figures come from a third-party traffic source, named with its date in the evidence box above; no one outside a site sees its analytics.
