What Is Local Ranking Factors 2021 and Why Does It Matter

Local ranking factors are the specific signals Google uses to determine which businesses appear in local search results when someone searches for a service in their area. In 2021, Moz released their biennial survey of local search professionals, asking hundreds of experts to rank the importance of various signals that influence local pack and local finder results. The study identified and weighted factors like Google Business Profile optimization, local citations, review signals, on-page local SEO elements, and link authority. For agencies and web designers serving local clients—plumbers, dentists, salons, home services, restaurants—understanding these factors became critical because Google's local algorithm was increasingly sophisticated, and ranking in the local pack (those three results shown in a map box) generated significant qualified traffic.

Why this matters for your agency is straightforward: local search is where most service-based businesses actually compete. Your clients aren't usually fighting for national rankings. A plumber in Denver needs to rank for "emergency plumber near me" in Denver, not nationwide. The 2021 factors study gave you concrete data about what actually moves the needle with Google's local algorithm, rather than guessing or relying on outdated SEO practices. This meant you could allocate client budgets more effectively, knowing which optimization efforts would realistically impact rankings. It also provided a foundation for client education—you could explain why you're recommending specific work, backed by research from trusted sources rather than vague best practices.

Practically, agencies should use this data to audit how thoroughly clients optimize their core local signals. Start with Google Business Profile completeness—this consistently ranked as the most important factor in 2021 research. Does your client have photos, business hours, accurate categories, and service areas filled out? Are they responding to reviews? This often costs nothing but time. Move to local citations, which means ensuring business name, address, and phone number (NAP) consistency across directories like Yelp, Apple Maps, industry-specific directories, and local chamber of commerce listings. Pull a report showing where citations exist and where they're missing or inconsistent—this gives you concrete work to propose.

For web designers, the 2021 factors research highlighted that on-page optimization for local intent still mattered significantly. This means title tags and meta descriptions should include location modifiers ("Denver plumber" not just "plumber"), and content should address local search intent. Schema markup for LocalBusiness, Service, and Organization became more important to implement correctly. Review signals ranked highly, so recommend implementing review request systems and helping clients actually respond to Google reviews, not just collect them. Rather than treating local SEO as a side service, frame it as the core service for location-based businesses.
