Hi Nyx,

Thank you for this question.

The answer is always, it depends, but let me share my thoughts on your specific case.

Making money online - one audience group

Traveling on a budget - second audience group

Two topics seem quite different from each other, which means one audience group might not be interested in the content you produce for the second audience group.

You might face a challenge in segmenting and monetizing your audience.

From the SEO perspective, you can succeed with one website. The more high-quality and authoritative content you publish on your website and elsewhere, the more Google will associate you with these topics, which will help your website grow.

I write about Medium, creator tools, and SEO on my website, and it works pretty well! My personal brand and optimized content help my website grow.
