I enjoyed the course and learned a lot from it. The academy is well organised and focused on practical disciplines such as SEO, PPC, Programmatic, Mobile and Display. I particularly enjoyed the bits of psychological research and discussions shared in our sessions. I would definitely recommend to those starting out and have interest in digital marketing. Well done to everyone involved at the course. And a BiG thank you to the entire TIPi team!

Accuracast Reviews & Testimonials
Dat Boi Review from Google
1.0★
Dat Boi's Review Sourced from Google
Unfortunately, my interactions with Farhad at Accuracast have been far from pleasant. Despite working on multiple projects together, the experience has consistently fallen short of expectations. Farhad's attempts to simplify complex procedures were ineffective, leaving me even more confused and frustrated, especially given my limited tech knowledge. It appears that he and the team lack genuine concern for delivering optimal solutions tailored to business needs. Overall, my encounters with Farhad and Accuracast have been disappointing, and I cannot recommend their services based on my experiences.
Sam Pitcher Review from Google
5.0★
Sam Pitcher's Review Sourced from Google
I've had the pleasure of working with Farhad at Accuracast on a few projects now and each time the experience has been outstanding. Farhad has a knack for breaking down complex procedures into understandable terms, which was invaluable to someone like me with limited tech knowledge. It’s clear that he, along with the team, really cares about finding the best solutions tailored to your business needs.
EUROUT Conference Review from Google
4.0★
EUROUT Conference's Review Sourced from Google
AccuraCast provided a swift, responsive, user-friendly and professional service. Farhad and Luke guided us patiently and efficiently through the process of devising our social media campaign (in the rather compressed timeframe we had given them to do so), and then smoothly project managed the implementation stage. We were especially impressed with how quickly and effectively they stepped in to resolve any technical or other issues that arose as the campaign unfolded, and supported us with last minute requests or changes from our side.

I have been working with Q-Online for a number of years now and can testify to their intense work ethic and creative thinking across many different platforms. Originally Q-Online were employed run our SEO campaign but as we were so impressed with their efforts we also brought them on to run our Social Media campaigns and build us a new website. They are a great team of hard workers who push the extra mile to get the job done and will go above and beyond the call of duty when they need to.
