Substack vs Medium vs traditional blogs: a practical guide

Substack, Medium and a traditional blog all put long-form writing on the internet, yet they are built around different publishing relationships. Substack centres the relationship between a writer and email subscribers, Medium centres reading and recommendation within a public network, and a traditional blog puts the publication, audience data and brand on a website controlled by the publisher. Calling them “blogs” can hide those operational differences.

For an Australian audience, the practical choice depends on whether the priority is a recurring newsletter, discovery through a large reading platform, or control over a durable publishing property. A Melbourne food writer, a Brisbane tech commentator and a regional community historian may reach readers through the same tools while needing very different systems. The format shapes income, workload, reach and legal responsibility, so it deserves more attention than the layout or subscriber count suggests.

What the three formats actually are

Substack is best understood as a newsletter platform with social publishing attached. A writer can publish posts, build an email list, issue a regular newsletter and offer paid subscriptions without managing a conventional website. The inbox becomes the main channel, while recommendations and cross-promotion help new publications find readers. That low technical barrier is attractive, although a growing list does not guarantee open rates, renewals or enough revenue to support full-time work.

Medium is a publishing network with its own feed, topics, editors and community. Articles can be read directly on the platform, followed, responded to and included in email digests. Medium’s Partner Program and member-support options can facilitate income, with eligibility and payment arrangements subject to the platform’s current rules. Compared with Substack, writers have less control over the direct publishing relationship and gain a ready-made discovery layer for readers who arrive through search or recommendations.

A traditional blog is a publisher-owned web property, often powered by WordPress, Ghost, Webflow or a similar content management system. The publisher manages the domain, hosting, design, email delivery and backups, and can combine editorial posts with a newsletter, membership area, shop or event listings. This route costs more time and money, but it supports custom functionality, search visibility, data ownership and a brand identity that does not depend on one platform’s algorithm.

Discovery, reach and audience ownership

The main difference in reach is between platform discovery and direct access. Medium can place a writer in front of readers who browse subjects rather than subscribe to a particular newsletter. Substack can surface posts through recommendations and network effects, but the stronger long-term channel is usually the email list. A traditional blog may rank in Google for years and attract links from other sites, yet new visitors often arrive through social media, search or word of mouth.

Daily habits matter. A reader on a peak-hour train from Sydney’s suburbs to the central business district may scan newsletters on a phone, save a thoughtful piece for later and never open the publication’s website. The same pattern is common on Melbourne trams, while community updates around Brisbane often circulate through email lists and local Facebook groups before appearing on broader platforms. Email is therefore a strong direct channel for Australian readers, but discovery still matters when people do not yet know a writer exists.

Audience ownership is more nuanced than the word “subscribers” suggests. Readers can follow a Medium author without receiving a regular email, while a Substack subscriber may be accustomed to one weekly publication and reluctant to move. Exporting contacts and posts, maintaining backups and documenting canonical URLs gives a publisher options. If a live page is changed or removed, a guide to archived page versions can help locate an earlier copy, although archives should complement, not replace, the publisher’s own records.

Revenue, pricing and operating costs

Substack generally lets writers publish without an upfront fee and can earn from paid subscriptions; the publisher then pays the platform’s fee and payment-processing charges. It also supports free posts, which some writers use to build an audience before charging. Medium offers several ways to monetise reading, including memberships through its partner arrangements. Traditional blogs use a wider mix: display advertising, sponsorships, affiliate commissions, subscriptions, products, events and professional services.

The operating economics can favour a familiar platform because hosting, software, security and email delivery are bundled. A traditional site requires a domain and hosting in any case, plus renewals, plugins, updates, backups and technical support. Australia’s publishing market is fragmented, with national platforms competing against local publications, member-funded organisations, trade magazines and specialist creator newsletters. When comparing a $12 monthly subscription with advertising or affiliate income, Australian creators should model gross revenue rather than headline earnings, account for tax, refunds, bad debts and unpaid administration, and separate business income from personal spending.

Commercial design creates another practical contrast. Readers accept promotions when they are labelled and relevant, whereas a conversion-focused page can make editorial trust harder to see. Weekly tournament offers illustrate the kind of direct-response layout used in specialised affiliate marketing: a narrow proposition, prominent action buttons and little emphasis on extended reading. A publisher using similar techniques should preserve an unmistakable line between editorial coverage and sponsored material, then measure whether the short-term revenue damages repeat visits.

Writing workflow, design and technical control

Substack’s editor and email preview make it convenient to draft, format and schedule a post in one place. Medium offers a similarly streamlined writing experience and a distinctive reading layout that many writers leave largely untouched. A traditional blog gives more control over typography, navigation, calls to action and related content, but those freedoms introduce theme updates, plugin conflicts, accessibility checks and the need to test how pages behave across browsers and devices.

Multimedia can extend any of these formats, although the production burden is often underestimated. Short-form repurposing adds another step; a guide to downloading subtitled MP4 videos can assist with clip preparation when a creator owns the source footage and has permission to edit its captions. Australian audiences may watch on a phone during a commute or listen while walking the dog, so captions, transcripts, alt text and clear audio can determine whether the material is useful beyond the creator’s own screen.

Control also affects collaboration and archiving. Several contributors can work in a traditional content management system, and its database can hold years of material in a consistent structure. Substack and Medium reduce setup work and can make cross-posting easier, yet changes to themes, account access or platform policy can alter the reading experience without notice. Teams should keep an editorial calendar, reusable assets, source files and a quarterly export routine, whether they publish through a platform or an independent site.

Australian legal and market considerations

Audience data can create obligations under the Privacy Act 1988 and the Australian Privacy Principles when a covered publisher or email provider collects personal information. Commercial email also engages the Spam Act 2003, which requires consent for covered messages and a clear way to identify the sender and unsubscribe. A newsletter sign-up should distinguish the requested subscription from unrelated marketing, explain how subscriber details will be used and provide an accessible unsubscribe route. Platform tools can help, but they do not remove the need for a documented data-handling process.

Copyright and reputation risks remain the writer’s responsibility. The Copyright Act 1968 governs the copying and publication of text, images, audio and video, so linking to an article or including a short quotation does not automatically make every reuse lawful. Defamation law under federal and state or territory legislation can also apply when an article identifies a person or business and harms its reputation. Reviews, allegations and reports based on user-supplied claims deserve particular care, and legal advice is appropriate when the potential consequence is serious.

Sponsorship and affiliate links require transparency under the Australian Consumer Law and related advertising rules. An online casino landing page illustrates why a publisher should inspect the destination before sending Australian readers there; interactive online casino services face significant federal and state restrictions in Australia. Age rules, licensing claims and the location of the service must be checked, while prohibited targeting cannot be disguised by affiliate labelling. A labelled advertisement can still mislead if its claims are false or the commercial relationship is concealed.

The local commercial setup also affects pricing. Australian readers expect prices in Australian dollars, and GST treatment for digital subscriptions depends on the seller’s structure and the transaction. A creator earning regularly from publishing may need an ABN, a business account and GST registration if their turnover and circumstances require it. Payment-provider fees, foreign exchange costs and platform commission can materially change a small membership base, so comparisons should focus on net income after every deduction. An Australian accountant can help when publishing becomes a substantial business activity.

The best format is the one that matches the intended reader relationship. Use Substack when a dependable inbox and direct subscriber relationship are central, Medium when its recommendation network can attract readers beyond an existing list, and an independent blog when brand control, custom features and long-term ownership justify the extra work. Many publishers combine two, using one as the public home and another as the acquisition channel.
