Brick-and-mortar companies, often multi-location businesses operating under franchises or cooperatives, will benefit greatly from applying local SEO best practices across their websites.
This includes unique factors compared to general SEO such as local citations & keyword-rich reviews across local listings. Exceptional profiles on third-party industry sites, or vertical search engines, also matter greatly.
I’ve helped companies within solar, automotive, legal, various contractor (flooring), higher education/university and many other industries.
Nonetheless, SEO require its own specialization. This means that anything to know about a business should come from internal employees and not SEOs familiar with that field. Improving SEO depends on knowing SEO itself and leveraging company resources, not industry knowledge!
