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.

Top Digital Marketing Agencies in Charleston

Local agencies speak the language of Charleston consumers and industries—from hospitality on King Street to aerospace suppliers near Boeing’s North Charleston campus. Choosing a hometown partner offers:

  • First-hand knowledge of seasonal tourist peaks and off-season demand
  • Easier in-person workshops and on-site content creation
  • Compliance with South Carolina privacy regulations
  • Relationships with regional media outlets and influencers like Holy City Sinner For businesses targeting the Southeast, that regional insight often translates into faster campaign traction.

Most Charleston agencies charge $100–$175 per hour. Monthly retainers fall between $3,000–$15,000 depending on scope—think organic SEO versus omnichannel performance marketing. One-time projects such as a paid ads audit or website redesign may start around $5,000. Always request a detailed proposal with KPIs, deliverables, and billing terms before signing.

Charleston agencies frequently work with:

  • Tourism, hospitality, and restaurants
  • Real estate and property management
  • Healthcare and telemedicine (MUSC spin-offs)
  • E-commerce and consumer goods
  • Aerospace, logistics, and manufacturing along I-26 Many also support nonprofits and higher-ed institutions seeking to amplify community impact.

Here are some guidelines you can follow:

  • Define goals (e.g., 30% traffic growth or 4:1 ROAS).
  • Shortlist agencies on Clutch with relevant case studies and verified reviews.
  • Evaluate their strategic process, tech stack, and reporting cadence.
  • Request local references—successful campaigns for other Charleston brands are a plus.
  • Compare proposals side-by-side, focusing on transparency, cultural fit, and measurable milestones.

Watch out for companies that:

  • Guaranteed #1 rankings or overnight results
  • Ownership of your ad accounts instead of shared access
  • Vague deliverables or missing analytics benchmarks
  • High staff turnover with no dedicated account manager
  • One-size-fits-all packages that ignore Charleston’s unique seasonality
