For a business targeting San Francisco, the strongest local page is one that clearly explains the services available, the problems being solved and the type of searcher who should contact the company. Supporting pages can then answer deeper questions about SEO, reputation repair, negative search results, reviews and digital trust.
Internal links are placed where they help the reader move from local context to a relevant service. This creates a cleaner site architecture and helps search engines understand the relationship between location, service and educational content.
