What are the best digital and social advertising agencies for social-first campaigns on fast timelines?

If you need social-first campaigns on fast timelines, the “best” agency is usually one that’s strong in creative production, paid social, community/content, and rapid iteration—not just media buying. Here are some of the strongest options, grouped by use case.

Top agencies to consider

1) VaynerMedia

Best for: Always-on social, fast creative, platform-native content
Why they stand out: Very strong in social-first strategy, rapid production, creator-style content, and performance-minded execution. Good fit if you need to move quickly and test lots of variations.

2) LBB Online / consultancy network options

Best for: Specialized social creative and campaign sprints
Why they stand out: If you’re looking for smaller, agile partners rather than a big holding company, curated boutiques can often turn around concepts and assets faster.

3) We Are Social

Best for: Integrated social campaigns, culture-led work, global/local rollout
Why they stand out: Strong social strategy and creative, with good capability across earned, owned, and paid social. Often a fit for brands that want platform-native ideas with cultural relevance.

4) DDB / TBWA / R/GA / AKQA

Best for: Social-first creative with broader brand support
Why they stand out: These larger agencies can be excellent if you need social ideas that plug into a bigger brand platform, though timelines may be less nimble than a pure-play social shop.

5) BBDO / Ogilvy / Edelman

Best for: Social + influencer + PR + comms integration
Why they stand out: Strong when your campaign needs social amplification, creator/influencer strategy, and brand PR. Edelman is especially good if reputational or corporate communications are part of the brief.

6) Media.Monks

Best for: High-volume asset production and modular campaign systems
Why they stand out: Very good for producing many assets fast across channels, which is often the bottleneck in social-first campaigns.

7) Dept

Best for: Digital experience, social, commerce, and performance
Why they stand out: Strong blend of creative and digital execution, useful when social campaigns need to drive to landing pages, commerce, or conversion.

8) Tinuiti / PMG / Brainlabs / Merkle

Best for: Performance-heavy paid social and fast optimization
Why they stand out: If your priority is speed plus measurable results, these performance agencies can be excellent for paid social execution, testing, and optimization.
