      Smartsites was incredibly strong from the start. Our onboarding introduced us to our Senior PPC Analyst who has been consistent with us throughout. Anthony has been prompt in his responses to us and will work with his other team members to find solutions for our proposed changes. Any questions we have are addressed quickly and with complete professionalism. I trust that we are making the right decision with any campaign management changes with him in charge.

    • PPC Services for Automotive Parts Company

      Rich is extremely responsive to my every request, which can be a lot sometimes. He leaves no stone unturned when it comes to advertising for our business and keeps me very informed on any updates in a timely fashion. The working relationship between myself and my analyst, Rich, could not be a better match. I know he's great at his job and I never question his insight or recommendations. They're absolutely great at what they do and I trust them 100%!

    • Web Dev & SEO Services for Automotive Parts Retailer
      5.0 Oct 24, 2022

      The most impressive thing about SmartSites is their ability to actually do what they say and do it very well. We worked with other website development companies in the past who would promise all these great things, but would never follow through. However, in the first month of working with SmartSites we saw their attention to detail, how they would quickly respond to our questions, and how they would actually complete the tasks effectively. In today's day and age, it is quite difficult to find a company that is reliable and trustworthy. But with SmartSites, you definitely get that and much more.

      SmartSites delivered results for us in getting traffic to our site and conversions. They are very easy to work with and up front with everything. Whenever we had questions or concerns about the campaigns or the plan of action, they were quick to respond. We would highly recommend them...they are reliable, trustworthy, knowledgeable, and they deliver real results. Anthony in particular is a pleasure to work with.

Why Trust Clutch

At Clutch, we believe trust is the foundation of every business relationship. Our mission is to help buyers make confident, data-backed decisions informed by real client experiences.

Every review on Clutch undergoes a rigorous, human-led verification process to make sure it’s valid. Our team of specialists confirms the identity of each reviewer, ensures the project is legitimate, and only publishes reviews that meet our strict criteria.

Verification doesn’t stop at the point of publication. Our Trust & Safety team routinely audits older reviews against our guidelines. When reviews fall short of our standards, we remove them.

We evaluate service providers using a structured methodology that combines:

  • In-depth client interviews and ratings
  • Comprehensive project details
  • Market presence
  • Portfolio examples and industry recognition

This data powers tools like the Leaders Matrix, which helps you compare agencies directly. Our research team curates rankings by weighing verified reviews most heavily, so the most trusted and experienced providers rise to the top.

Using this unique combination of verified client feedback and provider-supplied insights, Clutch distills the most important details into clear, digestible summaries so you have everything you need to make confident, informed decisions quickly.

We take fraud seriously. Providers who violate our guidelines may face lower rankings, restricted visibility, or removal from the platform altogether.

Clutch’s commitment to transparency is ongoing. We’re constantly refining our systems to protect the integrity of reviews and support you in finding the right agency.
