Espial Solutions Reviews & Testimonials

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.

SEO Review from Saurabh Agarwal
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.

Digital Marketing Review from Rajeev Mehta
Working with them is quite fluid, they are available 24 hours of the day. Thanks to the work of Espial Solutions, website traffic increased and sales grew by almost 50%. The workflow is fluid, as the team is available all day. The client is impressed with the analytical way that Espial Solutions did their work, studying the business model first before starting.Â

EBQ Reviews & Testimonials
Applied Tech's Review Sourced from Google
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.

Rebecca Jenkins's Review Sourced from Google
I availed ghostwriting services from House of Publisher, and they also provided me with a complimentary book cover. This really built my trust in them. They handled my project with completed all the work within the given timeframe. Everything delivered perfectly on time. I highly appreciate House of Publisher for their excellent work.
Mike Hedson's Review Sourced from Google
House of Publisher did everything for my book they handled the writing, editing, proofreading, formatting and even publishing it on all platforms, including Amazon. When they first told me they would take care of everything I honestly could not believe it. But now I truly do because they worked with such dedication and honestly. I'm so happy that my first book is finally complete and published. That's why I want to say a few words of appreciation for them.
