      PPC Review from Ahmed Iqbal Khan

      Espial worked for us to deliver quality leads through PPC campaigns. Our challenge was that we hardly had 1% conversion from all the clicks that we were getting through Google Adwords. Within a month our lead to conversion increased from 1% to 5%, that was a remarkable achievement. They know which design and content works best. The level of communication and responsiveness that we receive from them makes them incredibly easy to work with.

      We are very satisfied with the services received so far in these 7 months. Because of Espial Solution's efforts, the site's traffic boosted and most keywords used got high-rankings on Google search. As a result, the client receives more organic conversions and customer satisfaction. The team is very professional and punctual.

      We have been working with EBQ since July of 2024. It has been a seamless and rewarding experience, thanks to their exceptional project management and commitment to timely delivery on multi-project fronts. From the outset, their team demonstrated a clear understanding of our objectives, has maintained open communication, and has provided regular updates on progress. Milestones have been met with precision, and any challenges have been addressed proactively, ensuring the projects stay on track. Deliverables have not only been completed ahead of schedule but also have often times exceeded our expectations in quality and attention to detail. Their professionalism and dedication has instilled confidence throughout the process, making them a trusted partner for ongoing and future collaborations.

      Sarah Becherer's Review Sourced from Google

      Worked with EBQ on a sales outsourcing project for 6 months in 2024. Can't say enough positive things about how attentive, friendly, and responsive the team is. They're organized and excellent problem-solvers. Due to the nuances of our business and sales process, it ultimately wasn't a long-term fit, but I would highly recommend EBQ for cold-calling and appointment-setting for B2B software or managed services. Shout out to Dante who was with us since the beginning – you rock!

      Rodane Williams's Review Sourced from Google

      I contracted EBQ for BDR augmentation services for a period of three months, and the results were extremely disappointing. Despite their promises, they failed to schedule even one initial meeting with potential clients. It was clear from the start that they didn’t fully understand my organization, our business needs, or how to properly present us to potential leads. Instead of delivering on their commitment, they merely provided a list of cold calls that didn’t meet our business requirements at all. The leads were irrelevant, poorly targeted, and demonstrated a lack of research or effort. Despite their failure to achieve any tangible results, they had the audacity to demand thousands of dollars in funding for what was essentially a useless service. Overall, I found their approach disorganized and out of touch with our goals, making this engagement a waste of time and money. I would not recommend their services to anyone looking for real results.
