Klientboost Reviews & Ratings

4.8/ 5

803 reviews across platforms

Is Klientboost legit? Here is what verified third-party reviews on Clutch, G2, Trustpilot and other platforms say about Klientboost — including the strengths clients praise and the concerns they raise.

KlientBoost has clear third-party review presence on Clutch, G2, Trustpilot, and BBB, while I could not verify a company listing on Google or Capterra from search results. Across the platforms where it is listed, its reputation appears strongest on Clutch and G2, where ratings are high and reviewers commonly emphasize communication, transparency, expertise, and measurable marketing results; Trustpilot shows a much smaller and weaker review footprint, and I could verify BBB presence but could not reliably read customer review text there.

    Clutch describes KlientBoost as valued for cost, effective PPC/social management, and strong ROI outcomes such as reduced CPA and increased lead generation. Review insights on the profile also highlight communication, timeliness, transparency, and a data-driven approach, with some mention of room for improvement in creative services.

    G2 shows a strong overall rating and surfaces recurring themes around communication, collaboration, partnership, and expertise. Its pros/cons summary also indicates some reviewers mention expense, miscommunication, lack of expertise, inefficiency, and communication issues.

    Trustpilot shows only a small review footprint for klientboost.com and a relatively low TrustScore. The page confirms the profile is for the klientboost.com domain and notes the company has not replied to negative reviews.

    I verified a BBB Business Profile for Klientboost in Costa Mesa, CA under Digital Advertising. The search snippet confirms it is not BBB accredited, but rating/review details were not clearly visible in the accessible search/open results I could inspect.
