An independent, evidence-based evaluation of Klientboost, performance marketing agency focused on hitting bigger goals.. Scored across 5 weighted criteria covering website presence, search visibility, trust, market presence, and customer satisfaction.
Overall evaluation score
KlientBoost positions itself as a goal-driven agency that connects marketing execution to financial impact, monitors goal pace against time, and recommends where the next marketing dollars should go to drive revenue, profit, pipeline, or lead goals.
Weight: 20%
KlientBoost has a substantial first-party web presence with dedicated home, about, contact, pricing, services, B2B marketing, and LinkedIn Ads pages, plus clear contact details and a detailed service lineup, which indicates a strong website footprint from the evidence provided.
Weight: 20%
Search visibility evidence is limited to firm domain signals—klientboost.com is ~13 years old and the homepage was last modified in June 2026—but there are no actual traffic, rankings, backlink, or SERP visibility metrics in the bundle, so this should be scored only moderately.
Weight: 20%
Trust is supported by verifiable firmographics (Costa Mesa address, phone, email, 51-100 employees, Crunchbase profile, BBB business profile) and strong review performance on Clutch (4.9/5 from 402 reviews) and G2 (4.8/5 from 397 reviews), though the non-accredited BBB note and weak Trustpilot score temper an otherwise high score.
Weight: 15%
KlientBoost shows solid market footprint through a multi-page service website, third-party presence on Crunchbase, Clutch, G2, Trustpilot, BBB, and directory-style pricing mentions, but the absence of evidence like founding date, broader media coverage, or stronger search/brand reach data keeps it below top-tier.
Weight: 10%
Customer satisfaction appears strong overall because Clutch (4.9/5, 402 reviews) and G2 (4.8/5, 397 reviews) both show large, highly rated review bases with recurring praise for communication, transparency, collaboration, and results, although Trustpilot is weak at 2.6/5 with only 4 reviews and some G2 cons mention miscommunication and expense.

KlientBoost does not publish fixed package prices or standard plan tables on its own website; instead, it asks prospects to request a custom marketing plan and says it will provide multiple pricing options based on goals, timelines, strategy, and team size. The concrete numbers I found are mostly directory figures rather than first-party price sheets: Clutch lists a $1,000+ minimum project size and $100-$149/hr hourly rate, while DesignRush lists a $1,000-$10,000 minimal budget and $100/hr average hourly rate. KlientBoost’s own Google Ads service page discusses common pricing structures—flat monthly retainers of $2,500-$15,000+, percentage of ad spend at 12-30%, and performance-based pricing with a base retainer plus bonuses—but this appears to describe industry/common models for this service category rather than a firm, binding public price card for KlientBoost.
Where this pricing information was traced from.
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.
402 reviews
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.
397 reviews
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.
