The four types above cover the theory well. If I were starting from scratch on a small business site, I'd sequence it like this over the first 90 days:
1. Google Business Profile — claim it, fill every field properly, add real photos, and start a routine of asking happy customers for reviews. For a local business this usually moves the needle fastest.
2. Site foundations — check the site loads quickly on a phone, every page is HTTPS, and fix any broken links. Google Search Console is free and flags most of this for you.
3. Content that matches intent — give each service its own page with a clear heading, and if you serve several towns, a genuinely useful page for each one with local detail. Then answer one question your customers ask before buying as an article each month — cost guides, how-to-choose pieces.
4. Reviews and mentions — treat off-page as the slow burn. Don't buy links. Steady genuine reviews and accurate listings do more over time.
The order matters: there's little point chasing links to pages that don't convert or a profile that's half-empty.
