The short answer
A full-service marketing agency coordinates several channels — SEO, social, paid advertising, and content — as one strategy rather than selling them as separate retainers. The practical difference is that the channels inform each other: what ranks organically shapes what is worth paying for, and what converts on paid shapes the content plan.
The phrase is used loosely. In practice it should mean one team owning the channels together, with a single view of what is actually producing leads, rather than three vendors each reporting on their own slice.
If organic search is the main channel and the site has real technical debt, a dedicated SEO engagement will usually go deeper than a multi-channel retainer. Full-service is the better fit when several channels need to move together.
