SEA Agency

On the figures that drive decisions at your company. We feed your real costs, your margin per product, the share of new customers and the value observed over time into the bidding strategies, so that the campaigns optimise on your commercial reality.

How far this goes depends on what your information system exposes. We start by looking at what is available, then we build the signal with your teams.

It is worked out from your own market. The useful amount depends on the cost per click on your queries, on your conversion rate and on what a customer is worth to you. On an uncontested niche, a few hundred euros a month already produces learning. On a tight market, you need enough to feed the automated bidding so it moves past its learning phase.

We size that threshold during framing, from the real volumes of your market, and we say whether the channel holds up against your other options.

On a fixed price against a written scope, in most cases. An audit or a restructuring is sold as a project, with its deliverables and its end date. Ongoing management is sold as a monthly run, with what is included each month and a backlog decided together.

Your media budget stays with you and never passes through us: our fees and your ad spend are two separate lines. You keep ownership of your accounts, your data and the documentation produced.

We always start by reading what is already there. A running account carries conversion history that has value, and destroying it costs weeks of learning.

The audit says what to keep and what to rebuild. When a restructuring is called for, it happens in waves, with a dated plan approved before the first change, so performance keeps running through the work.

We read them as a single search territory. In practice, we look at paid and organic performance together to spot the overlap, brand queries in particular, and we adjust paid coverage accordingly.

SEA also works as a laboratory: conversion rates observed by purchase intent tell you which pages deserve a content effort. Our SEO and GEO offering takes over from there.

It answers the question attribution leaves open: among the conversions credited to the campaigns, which ones would have happened anyway?

Depending on the context, we use a geo-lift test, a Causal Impact analysis on a budget cut, or marketing mix modeling. The protocol is framed before anything is launched: which decision depends on the answer, what precision is reachable, and whether the test is worth running. When the answer is no, we say so.
