Most local SEO advice is written for brick-and-mortar businesses — restaurants, dentists, plumbers. Web design agencies have a fundamentally different profile: no walk-in foot traffic, clients who might be twenty miles away or in the next county, and a service that is genuinely hard to photograph for a Google Business Profile.
That difference creates both a challenge and an opportunity. The challenge: Google's local algorithm is built around physical proximity and in-person visits, so agencies serving a metro region rather than a single zip code have to work harder to establish geographic relevance. The opportunity: most of your direct competitors are ignoring local SEO entirely, chasing national rankings for keywords like "web design company" while leaving the Map Pack wide open in their own backyard.
In our experience working with professional service firms, the agencies that dominate local search are not necessarily the largest or the best — they are the ones who treat local SEO as a deliberate system rather than an afterthought. That system has three components: Google Business Profile optimization, on-site geographic relevance, and off-site local authority signals. Each supports the others, and weakness in any one limits what the others can achieve.
One more thing worth stating clearly: local SEO for a service-area business (which is what most agencies are) is governed by slightly different rules than for a storefront. You can serve clients across a wide region, but Google still anchors your local relevance to your registered business address. That address becomes your starting point, and everything else is about expanding your geographic reach from there.
