Search is how strangers check whether you know their problem. SEO is not a trick on top of the site. It is the site: one URL, one intent, proof, and a next step.
Intent before keywords
A query is a job. “How to connect Stripe” wants steps. “Hire a developer” wants a person. Do not write the same article for both.
Pages that rank and sell
Clear title. First paragraph answers. Headings match how people speak. Links to the thing you actually sell. Speed and mobile are table stakes.
What not to do
Do not publish thin encyclopedia notes to “have content”. Do not chase volume for words you cannot serve. One useful page beats twenty summaries.
