Professional Diploma in Digital Marketing, Social Media & Influencing Testimonials

Philip Noone

My team felt the course was very relevant to what we are executing and prised it highly for the hands-on focus looking at real solutions in the company to our digital marketing strategy. I think they really enjoyed the lecturer’s approach and delivery of the course and are now applying it to our new re-focus on the digital marketing at the company. I had 3-4 of the team attend another SEO / digital course on two occasions and it wasn’t a patch on this course. Based on that feedback I got, so happy to plug in other team members in the future.

Niall Hughes

City College Dublin's (Formerly City Colleges) Digital Marketing and Strategy diploma offered an excellent insight into the practical aspects of marketing. The course was extremely comprehensive and covered a broad range of topics that I have been able to apply to my current role, including setting up ad campaigns, using mail out applications such as Mail Chimp as well as devising an overall digital marketing strategy that could apply to specific industries. Grainne, our lecturer was so helpful throughout and always ensured each topic was fully understood before introducing a new one. She was also on hand to offer specific advice to the industry which each person in the class operated. The course was overall very informative and really helped me improve my understanding of the subject in a short space of time.

Mark Meehan

The Diploma in Digital Marketing for Business course brought me right up to date on best practice in the digital marketing industry. The course is very practical, with each session and exercise expertly tailored towards the goal of applying digital marketing to our own ventures. This real-world applicability has already brought me success. The skills I’ve learned have enabled me to secure an internship providing social media services for a leading international provider of anti-virus software. I’d highly recommend this course to anyone seeking to pursue in a career in any field, particularly those seeking to get involved in marketing and social media for businesses.

Kellie Meade

As the digital side of marketing is becoming increasingly important, we decided it would be a good idea for our sales and marketing team to get the most up-to-date information and learn the necessary skills to keep one step ahead of competitors. We had heard of Grainne Farrell and her passion for digital marketing, so decided to go with the course she taught in City College Dublin (formerly City Colleges). We weren’t disappointed. The 10-week course touched on all aspects of social media marketing showed us how to build and update websites, and taught us how to get the most out of the marketing campaigns we run. We were provided with constant support throughout the length of the course and given helpful, detailed feedback in our final assignment.
