Is TOP possible in different niches on the same domain?

Question

Search Engine Optimization

In addition to two thematic projects (where I write on one topic), I decided to start my own personal blog.
Now there are 15 articles, the domain is 7 months old, the traffic is small ~ 35 uniques, although I tried to make a competent text and optimize it using the same YOAST for WP.
And the question is this: Does the position in the PS of the article on different topics. For example, can I be in the TOP with an article about a recipe for a dish, a review of a mobile phone, a WP plugin, and an article about construction? Does Yandex give priority to sites that have one niche and subnises, or can the site have articles in different niches and be in the TOP for queries?

Answer 1

It doesn't matter, there are tons of top bloggers who write about everything in their lives.
