Everything starts from public, verifiable data. Strengths are written from each agency’s website; no rating or figure is made up.
Score = (reviews ÷ (reviews + 20)) × rating + (20 ÷ (reviews + 20)) × 4.98. 4.98 is the average rating of the verified pool. An agency rated 5.0 on 12 reviews therefore does not automatically beat one rated 4.9 on 90 reviews.
Ask for the name, seniority and availability of the person who will run your account every week, not just the one selling the engagement.
Separate management fees from any commission on the media budget: an agency paid as a percentage of ad spend has no reason to reduce it.
Ask to see the written method: phases, deliverables, criteria for moving from one stage to the next, and how experiments are prioritised and judged.
Ask for a real report: which metrics, how often, who comments on it and which decisions follow.
Ask for results with their context (starting point, duration, budget) and at least one client reference you can call.
Check that it already works with companies of your size and model (B2B or B2C, SaaS, e-commerce), on the channels that matter to you.

Lire l'articleGrowth hacking looks for a quick spike through low-cost tactics, often on a single channel. Growth marketing keeps the experimentation but makes it last, across the whole funnel (acquisition, activation, retention, revenue). Agencies in this ranking use either term; judge them on their method and channels rather than the label.
A digital marketing agency mainly coordinates acquisition channels (search, ads, social media). A growth agency adds an experimentation method across the whole funnel and often outbound, CRM and automation. Digital marketing agencies have their own comparison.
Agencies in this ranking usually charge a monthly fee, plus the ad budget (paid to the platforms) and tools (CRM, enrichment, email). Ask for a quote that separates these items and states the commitment period.
We start from our database of 4,648 agency listings taken from Google Maps. We remove closed, rejected listings and those with no website, no Google listing or fewer than 10 reviews, we merge duplicates (an agency present in several cities counts once), then we check on each agency’s website that growth marketing is the service it actually leads with. The remaining agencies are ranked by their Google rating weighted by review count (Bayesian rating). Ratings and reviews were checked on 29 October 2026.
No. No agency was contacted or paid, and none can buy its place. An agency that closes its Google listing or drops below the review threshold leaves the list automatically.
Uclic publishes this comparison and lists itself first, and says so clearly. Its position is not computed with the formula: the agencies that follow are ranked solely by their Google rating weighted by review count.
Senior leadership, certified media buyers, AI agents in production. No interns on your account: the team you meet is the team that ships.
