Blogger vs Substack: Which has the best future as AI develops?
My assessment is that both platforms have a future, but Substack may have an advantage in building a direct relationship with readers, while Blogger has advantages as a traditional website connected to Google’s search and advertising ecosystem.
The big question is what happens as AI changes how people find information, read articles and interact with the internet.
Let’s look at what this could mean over the next 5–10 years.
1. Google’s ambitions could change the future of Blogger
Google is working to make AI a central part of its products, particularly Search, Gemini and its wider advertising business.
This creates both opportunities and risks for Blogger.
The opportunity
Google could make it easier for people to create websites, research topics and publish useful content.
Blogger already benefits from being part of Google’s ecosystem, including its advertising and analytics services.
If Google continues developing its publishing tools, blogging could become easier and more accessible.
However, Google has not guaranteed that Blogger will receive major AI upgrades or become a central part of its AI strategy. Its future should not be judged solely on Google’s overall investment in AI.
The risk
Consider what happens when somebody searches Google for an answer.
Traditionally, Google presents links to websites. People click those links, visit blogs and potentially generate advertising revenue for their owners.
With AI-powered search, Google can sometimes answer the question directly.
For example, if someone searches for the best way to grow tomatoes, an AI-generated answer might provide sufficient information without the person visiting a gardening blog.
That could mean fewer visitors for some websites.
This is a genuine risk for Blogger publishers who depend heavily on search traffic.
However, the impact will vary. Detailed guides, original research, personal experience and specialist articles may still give people compelling reasons to visit a website.
My assessment: Blogger is unlikely to become irrelevant simply because of AI, but its users may need to adapt how they attract readers.
You can follow Google’s published approach to AI and search through its official Search Central documentation.
2. Why Substack could have an advantage
Substack has a different approach.
Instead of relying primarily on people discovering articles through search engines, writers can build an audience of subscribers.
When you publish a new article, you can send it directly to those subscribers by email.
This matters because you have another way to reach readers without depending entirely on Google Search.
Imagine you spend five years building a publication about personal finance.
You develop a readership that values your analysis and receives your articles by email.
Even if Google changes how it displays search results, you still have an established way to communicate with those readers.
There are important qualifications:
• Subscribers may stop reading or unsubscribe.
• You still need to attract new readers.
• Email delivery and engagement are not guaranteed.
• You remain dependent on Substack’s platform and policies.
Nevertheless, a loyal subscriber base can be a valuable asset.
Substack also allows writers to offer paid subscriptions, giving them a potential income stream that does not depend entirely on advertising.
My assessment: Substack’s audience model is well suited to a future in which direct relationships with readers become increasingly important.

3. What happens when AI can write almost anything?
This is perhaps the most important issue for both platforms.
Imagine that, in the future, anyone can ask AI to produce a polished article on virtually any subject in seconds.
The internet could become flooded with competent but similar-looking articles.
Simply publishing large quantities of generic content may become a less effective strategy.
What could distinguish successful publishers?
Original experience
People may want to read about what somebody actually did, experienced or discovered.
For example, an article about living in a particular town for 20 years could contain observations that a generic AI-generated article lacks.
Trust and reputation
Readers may return to writers whose judgement they trust.
This could be particularly important in areas such as business, technology, personal finance and specialist hobbies.
Original research
People may value publishers who collect information, investigate issues, conduct experiments or develop new insights.
Community
A publication can become more than a collection of articles. It can become a place where readers share interests and develop an ongoing relationship with the writer.
These advantages can apply to both Blogger and Substack.
The key is that AI may make producing content easier while making it harder to stand out.
4. Which platform is likely to make more money in the future?
There is no reliable way to predict which will generate more income for a particular publisher.
However, the two models have different strengths.
Blogger’s potential
Blogger may work well for websites that attract substantial search traffic and earn advertising revenue.
For example, a website containing useful articles about gardening, home improvements or specialist hobbies could continue attracting visitors long after those articles are published.
But if AI search reduces clicks to some websites, advertising revenue could come under pressure.
Blogger users may therefore need to diversify their sources of traffic.
Substack’s potential
Substack may work well for writers who develop a loyal audience willing to pay for ongoing content.
For example, a specialist writer might produce a weekly analysis that readers value enough to purchase a subscription.
The writer would not need millions of visitors to generate revenue.
However, paid subscriptions require readers to see enough value to justify the cost.
My view: Blogger is attractive for building an advertising-supported website, while Substack is attractive for building a subscription-supported publication. Neither model is guaranteed to outperform the other as AI develops.
5. The biggest difference: Who controls your relationship with your readers?
This is the issue I would pay the most attention to.
With a traditional Blogger website, you may depend on Google Search to bring people to your articles.
Google controls its search algorithms and can change how results are presented.
Your website may remain online, but the number of people finding it could change significantly.
With Substack, you can build an email subscriber list and send articles directly to those readers.
That provides another route to your audience, although Substack still controls the publishing service and you remain subject to its policies.
Neither arrangement gives you complete independence.
For a long-term publishing business, I would consider three things particularly important:
1. Your own domain name, so you have a consistent web address.
2. Backups of your published articles, so you can preserve your work.
3. A legitimate, exportable subscriber list, where available, so you have a way to maintain contact with your audience if you change platforms.
These measures help reduce your dependence on any single technology company.
6. My predictions for the next 5–10 years
These are informed judgements, not confirmed future developments.
Blogger
I expect traditional websites and blogs to remain useful, but publishers who rely exclusively on Google Search could face increasing uncertainty.
The strongest websites may be those that provide distinctive information, attract repeat visitors and develop audiences beyond search.
Blogger could remain a perfectly usable publishing platform, although its long-term competitiveness will partly depend on Google’s product decisions.
Substack
I expect email newsletters and subscription-based publishing to remain useful because they provide a direct communication channel between writers and readers.
However, Substack will face competition from other newsletter platforms, independent websites and AI-powered publishing tools.
Its future success will depend partly on whether writers and readers continue to value its particular combination of publishing, discovery and subscriptions.
AI itself
AI will probably become a more routine part of researching, writing, editing and distributing content.
The challenge for publishers will be to use it productively without producing material that is indistinguishable from thousands of other articles.
7. If I had to choose one today, which would I choose?
If I were starting from scratch and thinking primarily about the future of AI, I would lean towards Substack if my main objective were to build a loyal readership that I could reach directly.
My reasoning is that an established relationship with readers could help reduce dependence on changes to Google Search.
However, if my objective were to build a searchable website with the potential to earn advertising revenue over many years, I would still seriously consider Blogger.
I would not abandon Blogger simply because Google is investing heavily in AI.
The platform itself is only one part of the decision. Your subject, the quality of your content and your ability to attract and retain readers may matter more.
My final recommendation
If you want to build something that could survive substantial changes in AI and search technology, I would prioritise building an audience and a recognisable publishing identity, rather than relying on a single platform.
A sensible strategy could be to establish a website with your own domain and build an email readership alongside it. You could use Blogger for the website and Substack for the newsletter, although you would need to consider the extra work involved.
That approach could give you both a searchable library of articles and a direct channel to readers.
One important question
When you think about the future of Blogger and Substack, which of these concerns you most?
1. Google might eventually discontinue Blogger.
2. Google AI might reduce the number of visitors to blogs.
3. AI might make it difficult for ordinary people to earn money from writing articles.
4. You want to choose the platform that is most likely to remain relevant for the next 10 years.
You can choose more than one. Each concern has a different answer, and I can explain what the risks actually look like.
