Duffy Agency

The Duffy Agency specializes in SEO for international companies who target markets in multiple countries and languages. They work closely with their clients to ensure that SEO content is appropriately translated to provide tailored content for each target market. This is particularly important for clients with content that requires technical language or jargon that must be localized for each country.

  • Founded: 2009
  • Price Range: $$$$
  • Notable Clients: Cavidi, The UN World Food Programme
Summary of Online Reviews
Duffy Agency services are “ambitious“, but manage to find success “without increasing campaign cost“. Their results are often “quite good“, but must “build over a long period of time“.


Epsilon offers full-service marketing for enterprises, allowing companies with complex vendor management systems and onboarding processes who need a single agency to handle most or all of their marketing needs. They combine SEO with personalized messaging and customer data platforms to drive new leads to their clients.

Epsilon is “responsive to feedback” and provides “attentive project oversight” for their clients, but their services “are very costly.”

Marketing Eye

Marketing Eye specializes in technical SEO and strategic consulting. They help companies with strong content creation departments that lack technical expertise or SEO strategists optimize their existing content to generate SEO leads. They also provide web design and development services for clients with outdated websites, helping them avoid search ranking penalties for site security or mobile friendliness.

  • Price Range: $$

Summary of Online Reviews
Clients report that Marketing Eye  is “competent and professional” with “superior” service offerings, but employees report needing “additional training.”

Community Boost

Community Boost is the top SEO generation company that specializes in working with charitable organizations and nonprofits. Nonprofits see much better returns when investing in organic lead generation over paid lead gen, as establishing trust is particularly important when seeking donations from high net worth individuals and other sponsors.

  • Location: San Diego, CA
  • Founded: 2012
  • Price Range: $$
  • Notable Clients: The Trevor Project, The Humane Society, Seniors at Home
Summary of Online Reviews
Community Boost is “dedicated to their craft” and is an “incredible partner” for nonprofits, but still has “small tweaks to iron out“.

Clay Agency

Clay Agency places their focus on conversion rate optimization (CRO). This is because while high rankings will naturally attract visitors, organic traffic is only as valuable as a website’s conversion rate. Clay Agency’s expertise in UI/UX optimization is an excellent fit for companies that have strong organic traffic numbers but see few leads originating from their website.

  • Location: San Francisco, CA
  • Founded: 2016
  • Price Range: $$$
  • Notable Clients: Slack, Coinbase, UPS
Summary of Online Reviews
Delivering “top-notch quality” at a “competitive price“, Clay Agency pays “close attention to detail” and provides “high-quality design.”

Metric Theory

Metric Theory also focuses on increasing conversion rates, but does so by combining SEO with retargeted display ads and SEM. In addition to pushing a higher percentage visitors to convert, this also helps to alleviate SEO’s relatively long startup period, making them a good fit for companies who are willing to trade long-term ROI for short term results.

  • Location: San Francisco, CA
  • Founded: 2012
  • Price Range: $$
  • Notable Clients: GoFundMe, Lyft, LexisNexis
Summary of Online Reviews
Metric Theory conducts “thorough background research” and are “effective at capitalizing on revenue sources“, but teams would “benefit from having more resources“.


LocaliQ (formerly ReachLocal) specializes in providing small businesses with local SEO. Because visitors disproportionately click on the top 3 search results (which have a combined clickthrough rate of 68.7%), smaller businesses are best served by pursuing local strategies to avoid competing directly with the largest firms in their industry. For many companies, localized SEO is also necessary due to the nature of their business; for example, geographically remote leads are of little value to home services providers.

  • Location: Woodland Hills, CA
  • Founded: 2004
  • Price Range: $
  • Notable Clients: Skin Spa New York, Cadillac of Norwood, K-9 University
Summary of Online Reviews
LocaliQ is a “great asset” to their clients, offering “exceptional web design” and digital media services. Some former clients report “missed deadlines” and poorly optimized PPC campaigns however.
