Zelst

Zelst is a well-established digital marketing agency based in Harrogate, UK, with a secondary office in Boston, US. Founded in 2005 by Peter Van Zelst, the agency has built a strong reputation for delivering integrated search marketing campaigns that combine SEO, paid media, content, and social. Their tagline "Be Seen, Get Found" reflects a methodical, data-driven approach to helping clients achieve market leadership online.

The agency's core strength lies in its ability to craft bespoke inbound strategies that are "ordered, methodical, analytical and precise." They avoid scattergun tactics, instead focusing on pinpoint targeting across multiple channels. Services span the full digital marketing spectrum: from technical SEO and link building to PPC, programmatic advertising, content strategy, and social media management. They also offer data analytics and marketing automation, making them a viable partner for companies looking to consolidate their digital marketing under one roof.

Pricing starts at $2,500 per project, with typical engagements lasting 1-3 months. This positions Zelst as a mid-range option suitable for small to mid-sized businesses and even some enterprise clients. Their client base includes B2B services, ecommerce, fashion retail, food & beverage, and health & wellness brands. The agency's success stories demonstrate strong ROI: a 196.99% increase in search visibility for a legal client, a 28.11 ROAS on Microsoft Ads for a health and beauty brand, and a 266.90% increase in organic revenue for an ecommerce client.

Zelst is best for ambitious companies that want to dominate their niche online but lack the internal expertise or bandwidth to execute a multi-channel growth strategy. The agency's consultative style and focus on measurable outcomes make it a good fit for businesses that value transparency and data-backed decision-making. However, with a team of 10-49, they may not be the best choice for massive enterprise accounts requiring dozens of dedicated specialists.

Overall, Zelst is a reliable, results-oriented agency with a long track record and high client satisfaction. Their integrated approach and willingness to adapt to each client's unique needs set them apart from agencies that rely on one-size-fits-all solutions. If you're a UK or US-based company looking for a partner to drive sustainable online growth, Zelst is worth serious consideration.
