Case Study | How Castle Helped HNK Solicitors

HNK Solicitors

How did we help HNK Solicitors?

1. Client

HNK Solicitors are a specialist civil litigation firm, based in Liverpool. They have a team of multi-disciplined lawyers who help clients make compensation claims for a wide range of matters including data breaches, actions against the police, and criminal injuries.

 

2. Problem

HNK Solicitors came to Castle looking for a rebrand and a new website to facilitate lead generation. They also wanted Castle to generate leads for their range of services through paid advertisements through Facebook and PPC.

3. Solution

Castle designed and developed a brand-new user-friendly website optimised for maximum conversions. We then ran a social advertisement campaign for HNK Solicitors as a way to increase leads and conversions. This campaign was incredibly successful and obtained over 600 new leads for the client in just one month. These leads had an 8% conversion rate, around 48 people. The average case value for each case they took on was £1,000-£5,000. The social ads we created, therefore, led to an income of £60,000 a week in converted sales for the client.

4. Outcome

To achieve these results, we created four different social posts which massively varied in design. We did this so we could see which appealed most to people looking for these kinds of services. After running all four ads for a while, we discovered that the best performing ads were the ones that looked like news articles. Once we knew which was the most successful, we stopped running the other ads and put more of the budget into the best performing one. This led to a 62% increase in leads and a 79% decrease in cost. After just a month of running these advertisements, they generated over 600 leads and cost just £1650. With an 8% conversion rate, this means that each lead, which made them between £1000-£5000, cost them just £33.

Why GEO Matters More Than SEO in 2026

GEO is the shift from ranking on Google to appearing in AI generated answers. Instead of competing for a place on a results page, brands now compete to be included in the single response people receive when they ask ChatGPT, Meta AI or Perplexity a question. If AI cannot understand who you are, which market you serve or why you are credible, you will be excluded. GEO fixes that by clarifying your identity, removing digital noise and training AI models to recognise your expertise. It is the difference between being discoverable and being invisible in 2026.
