Agency retainer models
The commercial structures used for SEO services: monthly retainers, project fees, day rates, performance-based arrangements or hybrids.
BusinessResourcing model
In-house vs agency
The choice between building an internal SEO team, retaining an external agency or consultant, or operating a hybrid of both.
In full
In-house teams carry context, relationships and the ability to influence roadmaps, which is where most large gains sit; agencies bring cross-client pattern recognition, specialist skills and elastic capacity. The hybrid model — internal ownership with external specialists for migrations, digital PR or technical depth — is the most common at scale. The decisive factor is usually whether the organisation can act on recommendations, since advice without implementation capacity delivers nothing.
Example
A retailer hires one internal lead to own the roadmap and retains a technical specialist for its replatform.
