Yes. Many Social Media Marketing agencies in London work with remote clients. While a local agency can offer in-person meetings, remote collaboration is standard in the industry and gives you access to a wider talent pool.

### How does Pick an Agency rank social media marketing agencies in London?

Rankings are computed, never sold. No agency can pay to appear higher, and we take no money from the agencies listed. The default order uses a credibility-weighted score rather than the raw star average: a rating only earns its full weight once there is a real volume of reviews behind it, so a perfect 5.0 built on two or three reviews does not outrank a strong score backed by hundreds. That correction matters, because most agencies in this index sit at or near a perfect 5.0, which makes the star average on its own close to meaningless.
