# Promis Case Study: +1,418% Organic Traffic | AMA

> How Addiction Marketing Agency grew Promis, a London and Kent addiction and mental-health clinic, from 130 to 1,974 monthly organic visitors (+1,418%).

# How an established UK clinic turned its clinical authority into search authority

Promis is a respected London and Kent addiction and mental-health clinic with a strong domain, but it wasn’t capturing the searches its expertise deserved. A content-led program grew organic traffic from 130 to 1,974 monthly visitors and took it to #1 for major mental-health terms, including "eupd" at around 35,000 searches a month.

## Promis

Promis runs private addiction and mental-health treatment in London and at Promis Hay Farm in Kent, with a long clinical heritage and an already-authoritative website. The challenge was not credibility, it was capture: a trusted brand that wasn’t ranking for the high-volume mental-health and addiction questions its clinicians are expert in answering.

### Authority without capture

  **A strong domain, underused.** Promis already had high authority (Domain Rating 57) but ranked for few of the searches that matter.

  **High-value conditions.** Mental-health terms like "eupd" carry tens of thousands of monthly searches.

  **A content gap** between the clinic’s real expertise and what was published and ranking.

## Convert clinical expertise into ranked, useful content

### The challenge

- ×

  **Low capture.** 130 monthly visitors and just 24 page-one keywords despite a strong domain.
- ×

  **Untapped authority.** High Domain Rating that wasn’t translating into rankings.
- ×

  **A broad clinical remit** across addiction and mental-health conditions, none well covered.

### The opportunity

- ✓

  **Own condition-level searches.** Terms like "eupd" and "reactive depression" were winnable and high-volume.
- ✓

  **Leverage existing authority.** A strong domain means new content can rank quickly.
- ✓

  **Build a durable footprint** on genuinely expert, clinically-grounded content.

## Expert content on an authoritative domain

We mapped the conditions Promis treats to the searches people make, then published the expert content the domain’s authority could rank fast.

1

### Audit & opportunity mapping

We audited the site and mapped its clinical expertise against the highest-volume, winnable addiction and mental-health searches.

2

### Condition & treatment content

We published in-depth, clinically-grounded content on the conditions Promis treats, from personality disorders to depression and addiction.

3

### Authority & internal linking

We used the domain’s existing authority and a tight internal-linking structure to push new content onto page one quickly and into the top three.

4

### Continuous optimization

We tracked Ahrefs visibility and kept expanding the winning clusters, driving sustained growth through 2025 and into 2026.

## Authority, finally captured

With the right content, the domain’s authority converted into rankings, and traffic grew more than 14x.

## A condition term worth 35,000 searches a month

Ranking #1 for a major mental-health condition puts Promis in front of the exact people it can help, at the moment they search.

**#1 for "eupd"**

The top spot for a condition term with ~35,000 monthly searches, a category-defining position no ad budget could cheaply hold.

**14x organic traffic**

From 130 to 1,974 monthly visitors, with traffic value up more than 400% to $1,404/mo.

**Durable, content-driven**

Growth came from content, not links (Domain Rating held flat), so it is stable and keeps compounding.
