Biggest beginner mistake isn’t writing quality, it’s picking topics that are either too competitive or nobody’s searching for; aim for specific long-tail questions and answer them more clearly and completely than what’s currently ranking, ideally with your own experience mixed in. Google also just takes time to trust a new site, so months of quiet traffic is normal even when the content’s good, that’s not necessarily a “my writing sucks” signal. Beyond that, use your target phrase naturally in the title and opening paragraph, break things up with scannable subheadings, and try to get a few other sites linking to you, since backlinks often move the needle more than writing polish does.
