What customers say

Based on genuine customer reviews

Website design and development sit at the heart of the work customers describe, with bespoke business cards and graphic design also recurring, alongside video production, marketing consultancy and web hosting. Businesses mention drawing on the design and web teams when additional capacity was needed, and strategic campaigns involving paid advertising and affiliate marketing are referenced as part of the wider support. A theme running through the feedback is how quickly enquiries are answered and how carefully communication is maintained from the first conversation through to delivery.

Reviewers value the practical marketing advice they received, crediting it with helping them launch and then grow their operations through uncertain trading conditions. Transparent pricing is another point that comes up often, with no hidden charges reported and outcomes said to reflect what had been agreed beforehand. Dean is named for the generous time he devotes to clients, while the broader team is praised for sustained engagement that introduced businesses to new audiences. Support with building industry contacts is noted as a further benefit for those starting out.

We’ve been working with Connor and the team at Castle Marketing for several months now, and the results have been outstanding. They’ve completely turned around our online performance — Google Ads are running more efficiently than ever, Meta campaigns are consistently profitable, and our Shopify sales have seen real, measurable growth month after month. What really stands out is the communication and attention to detail. Connor is proactive, genuinely invested in our success, and always brings clear insight backed by data. Every week we get transparent reports, constructive ideas, and steady progress. A great team to work with — knowledgeable, reliable, results-driven but also very Friendly. We had worked with various other market companies over the last few years and most are just happy to take a monthly retainer and drop you company into the works profile. Castle work differently, work towards targets and genuinely want to grow and grow your company. I Highly recommend Castle to any business looking to grow their online sales properly.

We have recently started using castle to market our heating and plumbing company. So far everything is perfect. Leads are coming in and the communication from the team is outstanding.

I honestly can't say how good everyone is at Castle, they can't do enough for you and the work and numbers they produce out of this world. If I could leave 10 stars I would

I cannot thank Castle International enough for their outstanding customer service especially Lauren & Emily who are always there to answer any questions or concerns. Smashing targets & 24/7 support which is a big bonus for us can’t thank them enough. Connor who’s trying different strategies & believe me they bring in the results! We look forward to building an ongoing relationship for many years to come. I cannot recommend enough. Keep up the great work!

Excellent social media workshop with Shannon and Finbarr. The team were super professional and friendly and we got a lot out of the session. Will absolutely use their tips and planning methods going forward and would love to do some more training in the near future.
