USA Marketing Pros is creating an expert roundup article for small and medium-sized business owners about foundational local SEO mistakes that still hurt visibility in 2026. We’re looking for SEO consultants, agency owners, marketers, and local SEO practitioners with hands-on experience helping SMBs improve local search visibility. What is one foundational local SEO mistake you still see small businesses making in 2026, and what is the simplest way to fix it? Please keep your answer practical and specific. We are not looking for generic advice unless you can explain the exact mistake and the fix clearly for a small business audience. Helpful angles may include Google Business Profile optimization, customer reviews, review responses, service pages, location pages, NAP consistency, citations, schema markup, internal linking, page speed, mobile usability, website structure, content quality, or conversion issues that affect local SEO performance. Please include your name, role/title, company name, website URL, a 3–6 sentence answer, and any real example or observation from your SMB work, if available.
