SEO For Multiple Topics Under One Domain

I am curious about the possibility of ranking multiple topics under one domain name. As we all know, building up domain authority is difficult. If you wanted to start blogging about things like cars, nature, health, fitness etc. Would it be worthwhile doing it all under one domain?

A wordpress multisite would allow you to use a subdomain multi site so that you could build up domain authority for stuff you push around fitness, and it would end up benefiting all other sub sections as the domain would have more authority. Is this likely to work in practice?

You could, but i think it will be harder to rank as your site would be too "horizontal". Is like seeing wikiHow in the top serps, you they are huge, but since they cover so many topics a niche site can outrank a certain way query

Do you think the subdomain approach that the likes of stack exchange use would be a better way to build up the reputation of a domain but stop it being horizontal like you mentioned? so gardening.myblog.com, cars.myblog.com etc?

Think it would definitely solve it. What I would do is create a huge pillar post for each subdomain, preferably at the home page. That way, you can properly rank each subdomain keywords and pass linkjuice. Avoid linking between subdomains (my opinion) unless necessary (between pillar posts since they should be ranking ranking the most)

It's not worth it. Multi niche sites are by default much harder to rank than single niche sites. Relevancy is an important factor, even within the website itself.

Definitely do not bother with subdomains, considering that subdomains are treated like separate domains, you wouldn't help yourself at all.

Create a separate website for every niche, especially if you do not have much experience with SEO.

If subdomains are treated like separate domains, what is the downside of using one domain and targeting multiple niches through the subdomain rather than buying a new domain for every niche? Control over the name of a subdomain means I could use the niche name in the base URL, something that is harder if you buy a domain for everything. Wordpress multi-sites also make the management and maintenance a breeze of multiple websites.

Because if Google decides to penalize your entire domain, your subdomains will go down as well. Using new domains for money sites is becoming a thing of the past too. So over complicating everything and exposing your websites to Google further, because of maybe $50 saved makes zero sense.

Cutting corners from day 1 will get you nowhere.

I have the same problem. Its not only from a SEO perspective but also from costumer/visitor perspective. Lets say my page is about shoes. I have shoes special made for running and special made for bikes and last special made for pets (dogs and cats). Its very confusing when I go a little off-topic in my articles. For instance when we talk about the shoes for bicycles we also mention the different kind of locking mechanism on the bike. And we have articles about the type of pedals and bike accessories.

We have the same type of articles about pets. Like cats going outside in the winter. Where some other blogs about cats link to this article. On the articles about cats we get backlinks from cat webpages which is relevant within cat and also relevant for pets as a group. But it not relevant for running or for bicycles. On Wordpress next article will be about something totally different.

So if relevancy is key, then subdomains should be the way to go. We have a brand, so making many webpages with the same brand doesn't make sense. And in the end, everything is sold by the same local shoe-shop on the same local address.

But when retailers selling our brand link back to us, they link to our support page or main page. Our partners links to our main page. So we will lose most of this link juice, since the main page will only be linked to these 3 different subdomains.

So what to do?

Learn the site structure crom big media news sites like bloomberg
And there what you see on their "Home" page?

They rank with multiple topics= multiple times in the serp and their site structure is far beyond a simple siloing.

Ranking multiple topics under one domain can work, but stick to related themes to avoid confusing search engines and users. Using subdomains for each topic is an option, but they often get treated as separate sites, so domain authority might not carry over as you expect. A simpler approach is to organize different topics into categories on one site, focusing on building strong content and SEO for each niche. Keep it relevant and authoritative for each area.
