Matrix Internet Reviews & Agency Profile

About Matrix Internet

Matrix Internet is a Dublin digital agency that began in 2000 as a small web development studio. Its Irish base is Merchants Court on Merchant's Quay in Dublin 8, and it opened a second office in Brussels in 2024 to serve European clients. The agency now has a team of about 50 people, with members working from more than 20 countries. Jeff Sheridan is chief executive, Michelle Rafter is a director and Nicholas Cloake leads creative and brand work.

Its search offer grew over time. Its first eCommerce project came in 2008. In 2011 it brought SEO and campaign strategy in-house, which turned the studio into an integrated marketing agency. UK clients followed in 2013 and European Commission projects in 2022. Today the menu spans brand and UX design, website and app development, hosting, cybersecurity, GDPR support, paid digital marketing, data and analytics, digital audits, and an export marketing service for Irish firms selling abroad.

Their SEO follows a six-part method: competitor analysis, intent-based keyword planning, site structure work, technical fixes such as metadata, schema and 404 errors, content optimisation, and ongoing adjustment to algorithm updates. For businesses that serve a defined area, they offer local SEO built on location keywords, Google Business Profile management, local citations and review strategies, with the aim of appearing in map packs. Reports track rankings, traffic and page-level performance, and most clients see measurable change within three to six months. A senior SEO specialist, Srdjan Nikolic, sits within a wider team of content writers, PPC and paid social specialists.

Matrix Internet has no dental marketing page and names no dental clients. Its portfolio leans towards public bodies, charities, financial services and consumer brands, including AIB Future Sparks, Jigsaw, Volunteer Ireland, Lisney, Avoca, Dundalk Credit Union and the European Environment Agency. The closest health-sector project is the Health Research Board, whose research portal they rebuilt. A dental practice would therefore be buying general local SEO and web expertise rather than a dental-specific programme. It suits clinics that also want a new site, accessibility work or GDPR support from one supplier.

On Trustpilot the agency holds a 4.4 score from 12 reviews, all of them five stars, although most date from 2023. Reviewers point to clear communication, deadlines being met, website rebuilds that produced new enquiries, paid social campaigns, GA4 setup and training, and workshops for EU-funded projects. The agency is a Google Partner and was recognised at the 2026 Digital Media Awards. No prices, packages or contract terms are published; work is scoped per project.
