Stack Digital

Stack Digital is a performance marketing agency based in Stockton-on-Tees, UK, with a secondary office in Newcastle upon Tyne. Founded in 2019, the agency has quickly carved out a reputation as a go-to partner for businesses in the iGaming, e-commerce, and travel sectors. With a tight-knit team of eight seasoned professionals, Stack Digital focuses on delivering measurable online growth through a combination of search engine optimisation (SEO), pay-per-click (PPC) advertising, and content marketing. Their Semrush Agency Score of 4.9 out of 5 reflects strong client satisfaction and consistent results.

The agency's core strength lies in its deep vertical expertise. Stack Digital has worked with renowned casino brands such as Mobile Wins, LV Bet, Energy Casino, KTO, and Betway, consistently achieving top-5 organic search positions and driving substantial increases in player conversions. On the e-commerce side, they have delivered successful campaigns for brands like Skootz E-scooters, Maddisons of Durham, and Rebellious Fashion, optimising Shopify, WooCommerce, and Magento stores. Their travel SEO services help businesses in the travel and tourism vertical generate more bookings through targeted search strategies.

Stack Digital offers a comprehensive suite of services that go beyond basic SEO and PPC. Their capabilities include technical SEO audits, link building, content marketing, Google Ads management, Bing Ads, Google Shopping, paid social ads, and digital PR. They also provide Amazon marketing, branding, email marketing, and web development. This breadth allows them to act as a full-service digital partner for clients who need an integrated approach to online growth. The agency's pricing is project-based, starting from $1,000 per project, making it accessible for small to mid-sized businesses while still delivering enterprise-grade results.

Pricing is transparent and flexible, with budgets starting at $1,000 per project and no fixed minimum project duration. This makes Stack Digital a viable option for businesses that want to test the waters with a focused campaign before committing to a long-term retainer. The agency works with clients of all sizes-small, mid, and enterprise-and has a geographic focus that includes the UK, Italy, US, Canada, India, France, and Australia. All communication is in English.

Stack Digital is best suited for companies in the iGaming, e-commerce, and travel sectors that need a performance-driven partner with a proven track record. Their small team ensures direct access to senior strategists and a high level of personal attention, which is often lacking at larger agencies. However, businesses outside these verticals or those requiring massive scale may find the agency's niche focus limiting. For the right client, Stack Digital offers a compelling combination of specialised expertise, transparent pricing, and demonstrable results.

In conclusion, Stack Digital is a well-regarded boutique agency that punches above its weight in its chosen niches. With a strong portfolio of success stories-including a 40% increase in organic traffic for a clothing retailer and top-3 rankings for a mobile casino-they have the data to back up their claims. If you operate in iGaming, e-commerce, or travel and are looking for a results-oriented SEO and PPC partner, Stack Digital deserves serious consideration.
