Should you hire a Washington SEO agency or a remote one?
Most US SEO engagements run remotely regardless of geography, so the most important filter is almost never "Is the agency in my state?" — it's "Do they have demonstrated work in my industry?" A Washington-based agency may be the best fit if you're a service-area business targeting local Washington searchers, if you prefer in-person quarterly reviews, or if your legal or compliance environment benefits from a partner that shares your jurisdiction. Otherwise, consider the full directory and weight industry fit over location.
