Choose a niche (the decision everything else depends on)
A niche is the specific topic your blog focuses on. It determines who your readers are, which keywords you rank for, what brands want to advertise with you, and whether strangers recommend your blog to each other.
The best niches sit at the intersection of three things: something you know well, something you're genuinely interested in, and something people are already searching for. Hit all three and you have a blog that's enjoyable to write, easy to research, and able to attract organic traffic.
Avoid too broad: A "lifestyle" blog competes with millions of sites and gives readers no reason to subscribe. You become memorable when you're the go-to source for one specific thing.
Avoid too narrow: A blog for left-handed guitarists in Denver has an audience of about 12 people. You need a topic that's specific but has real search volume.
Good beginner niches to consider:
Personal finance for a specific life stage (new graduates, new parents, early retirees)
A cooking style or diet (high-protein meal prep, budget vegan, 30-minute dinners)
A career or industry angle (tech interviews, freelance writing, UX design careers)
A specific hobby with gear and skill depth (film photography, mechanical keyboards, sourdough baking)
A parenting niche (unschooling, raising bilingual kids, toddler activities)
