Digital Services Review from Paloma Anguiano
Overall I feel very confident working with Patrizia and Darius from Smart Site, they have given us clear explanations and accompanied us throughout the process for the growth of the brand. The attention to us is very fast and they advise us in an adequate way.

Digital Services Review from Brianna Porter
SmartSites impressed me from day one. They are knowledgable, kind, and most importantly keep things simple and streamlined so that even an SEO-newb like me can understand. Tiffany and Luna are my main points of contact and they are especially great! I would recommend to anyone looking for an agency to really take their website and digital presence to the next level.

PPC Review from Jim Curry
At first, a survey was conducted to gather company background, product information, target markets, etc. Next, accounts were established on various Google Business platforms, social media, etc. Then SmartSites created the ads and campaigns, and we were off and running in just a few weeks.

LeadBuds offers client reporting, help desk assistance, and technical support. Reaching customer CSAT scores, first call resolution, and call center response times. observant, capable, and exhaustive. capable of taking the lead in important areas pertaining to their services. They have tremendous industrial experience and leadership.

B2B Social Media Marketing Review from John Nicolosi
I was sent a thorough campaign questionnaire after registering that outlined the purpose of the project and my target audience. LeadBuds took those responses, created some brilliant message sequences, and created a LinkedIn prospect list that was specifically targeted. I made dozens of new connections and had six survey replies in the first two weeks of the campaign. These are lengthy questionnaires with in-depth inquiries. I've already had six answers, compared to my estimated 1-2. They know what they're doing based on the outcomes they provide, therefore I won't recommend changing. Continue as you are!

Business Consulting Review from Naomi Allen
LeadBuds takes care of our video labeling needs. With a 98% accuracy rate in video review, LeadBuds' agents can evaluate more than 350 video events in an hour. Since we are a technological firm, our goods and software are always changing and developing.

Steve Brandt's Review Sourced from Google
Working with the team at No Standing has been a great experience! A collaborative approach with experts that understand brands and the commercial realities of a fast moving market has been an asset to our business.
Paul Laskarides's Review Sourced from Google
Working with No Standing has been a game-changer for our gaming brand. As we launched into the Australian market, essentially operating as a start-up, their guidance on our go-to-market (GTM) strategy has been invaluable. Sohan & his team brought deep expertise and creativity, helping us navigate the complexities of market entry with ease. From branding to execution, they tailored everything to suit our specific needs, and their strategic insights ensured a smooth and successful launch. If you're looking for a partner who can truly elevate your brand and drive results, I highly recommend No Standing. Ross is a gun account manager too!

Petra Lehmann's Review Sourced from Google
I was receiving a lot of advertising emails for a while, and Performance Heroes was able to figure out that it was because I had participated in an online travel giveaway. Apparently, I had unknowingly agreed to receive these emails when I entered. However, they were able to help me unsubscribe, and since then I've hardly received any advertising :-)
Christoph Thate's Review Sourced from Google
Excellent collaboration! And a very nice young team. They know what they're doing. They've significantly improved our email marketing.
