Who We Are
One team for growth across markets and languages
COSEOM was founded in 2008 to solve a specific problem: international brands were buying marketing one channel and one country at a time, and losing the compounding effect of a single strategy. We built an agency where SEO, paid media, social and content sit in one team, run by senior specialists who speak the buyer's language in each market.
Senior people, one team
You work with specialists who own the work end to end. SEO, PPC, paid social and content coordinate in one plan, so channels reinforce each other instead of competing for budget.
Measured against pipeline
We report against revenue and qualified pipeline, with cost per acquisition and organic growth tracked every month. Vanity metrics stay out of the way of decisions.
How We Work
One transparent system, every engagement
The same method runs behind SEO, paid media and AI visibility, so you always know what happens next and how it ladders up to pipeline.
- 01
Listen & Audit
We learn your markets, buyers and numbers, then baseline where you stand in search, paid channels and AI answers per language.
- 02
Strategy
One plan across channels and markets, prioritised by the pipeline it can move and the effort it takes to get there.
- 03
Execution
Senior specialists build and run the work: technical SEO, campaigns, content and structured data, in every language you sell into.
- 04
Measure & Iterate
Results reported monthly against pipeline. What performs scales; what underperforms gets rebuilt.
