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!
Dean was very generous with his time and gave extremely useful advice for marketing strategies and ways to kick-start my business.
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.
Castle has been the best thing that has ever happened to my business! The level of service is incredible, their vision and foresight nothing but astounding, can't recommend them highly enough.
