Serpact is an internationally recognized SEO agency specializing in search engine optimization, content marketing, and website migration. With a 4.8 rating and over 95 reviews, they deliver data-driven strategies for competitive markets across the US, UK, and Europe.
Serpact positions itself as a "leading agency for SEO & SERP," and the data backs that claim. With a 4.8 rating from over 95 reviews on Semrush and Google Maps, the agency has built a strong reputation for delivering measurable organic growth. Founded in 2016 and based in Plovdiv, Bulgaria, the team of 10-49 professionals serves clients across the US, UK, Australia, and Europe, including highly competitive markets like Germany, Japan, and Sweden.
The agency's core strength lies in technical SEO and content marketing. They have completed over 75 website migrations and produce more than 100 full content marketing strategies annually, with a reported 50%+ integration success rate. Their "Performance SEO" model, highlighted on their website, is tailored for ecommerce clients, focusing on keyword-level transaction value rather than just rankings. They also emphasize AI search visibility, helping brands appear in AI-powered answers and Google's AI Overviews -- a forward-looking capability.
Pricing starts at $2,500 per project, with typical engagements lasting 1-3 months. Larger projects, like the $50,000 IaaS SEO campaign, run for 12 months. This makes Serpact a solid mid-range option for companies that need serious SEO work but aren't ready for six-figure retainers. The agency works with mid-market and enterprise businesses, and their client list spans ecommerce, fintech, IT, and media.
Serpact is best for companies that need a specialized SEO partner with deep technical chops and a content-first approach. If you're planning a site migration, targeting competitive international keywords, or looking to build a content engine that drives conversions, they have the experience and case studies to back it up. The team's responsiveness and project management skills are frequently praised in client reviews.
The only notable limitations are the team size and narrow service focus. Larger enterprises with massive ongoing needs may find the 10-49 person team stretched, and those looking for a full-service agency (PPC, social, email) will need to look elsewhere. But for pure SEO and content marketing, Serpact delivers a high-quality, results-oriented partnership. Their awards from European Search Awards, Web Excellence, and Clutch further validate their standing in the industry.
