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 SEO Website Migration Agencies

An SEO migration company plans and executes site moves, such as platform upgrades, redesigns, domain changes, or HTTPS transitions, while preserving existing organic traffic and search rankings. They audit the current site, map URLs, set up redirects, ensure crawlability, and monitor performance post-launch to catch issues before they impact revenue.

Typical offerings include:

  • Pre-migration SEO audits and risk assessments
  • URL mapping and 301 redirect strategy
  • Technical SEO implementation (schema, XML sitemaps, robots.txt)
  • Content consolidation and duplicate-content mitigation
  • Analytics setup and benchmarking
  • Post-launch monitoring, reporting, and quick-fix support

Many agencies bundle these with broader services like ongoing SEO, CRO, or web development to provide an end-to-end solution.

Budgets vary based on site size, complexity, and timelines.

  • Small brochure sites: $3,000–$7,500
  • Mid-size eCommerce or content hubs: $8,000–$25,000
  • Enterprise migrations with multiple domains or millions of URLs: $30,000–$100,000+

Hourly rates typically range from $100–$200. Remember to factor in post-launch monitoring for at least 30–90 days.

Start by short-listing agencies with documented migration case studies in your CMS or industry. Review client testimonials for evidence of traffic retention. During discovery calls, ask about:

  • Their migration framework and success metrics
  • Tools used for crawl analysis and redirect validation
  • Contingency plans if KPIs dip post-launch

A trustworthy partner will offer a transparent timeline, shared dashboards, and a clear rollback strategy.

Watch out for companies that:

  • Guaranteed rankings or traffic increases (no one can promise this)
  • Lack of a detailed redirect map or test environment
  • Reluctance to share past migration results
  • Minimal post-launch support
  • Vague pricing with hidden fees

If you encounter any of these, keep looking.

Follow these sample questions for your hiring process:

  • How many migrations like mine have you completed in the last 12 months?
  • Can you walk me through a recent success story, including traffic metrics 90 days post-launch?
  • Which team members will handle technical SEO, development, and QA?
  • What is your communication cadence during the freeze and launch windows?
  • How do you measure and report on post-migration performance?
  • What is the total cost, and what happens if timelines slip?

Specialists bring proven checklists, enterprise-grade crawl tools, and repeatable processes that reduce downtime and preserve revenue. For most companies, the one-time investment is far less than the potential loss of organic traffic caused by an inexperienced migration.

A general consultant may focus on ongoing optimization, whereas a dedicated migration agency has deep technical expertise, staging workflows, and cross-functional teams (SEO, dev, analytics) specifically trained for high-risk site moves.
