TL;DR
Local SEO targets customers in a specific area (“plumber near me”) and relies on your Google Business Profile and the map pack; national SEO targets customers anywhere and relies on content and authority. If you serve a geographic area, do local SEO; if you sell nationwide or online, do national. Some businesses need both.

The Core Difference
Local SEO is about proximity and place: ranking for searches with local intent and appearing in the map pack for your area. National SEO is about topical authority: ranking for searches anywhere, regardless of location. The right one depends entirely on where your customers are and how they buy.
Local SEO and Who Needs It
Local SEO relies on your Google Business Profile optimization, consistent business listings, reviews, and location-relevant pages. It is essential for any business serving a geographic area, contractors, clinics, restaurants, med spas, because most of their customers search with local intent and choose from the map pack.
National SEO and Who Needs It
National SEO relies on deep content, technical SEO, and authority signals like backlinks. It is the right approach for e-commerce, SaaS, and any business selling nationwide or online where location is irrelevant to the customer. The competition is broader, so it usually takes longer and more content.
Which Do You Need?
If customers come to you or you go to them within an area, do local SEO. If you sell anywhere, do national. Multi-location and hybrid businesses often need both: local SEO for each location plus national content for broader authority. Start where your customers actually search.
