Case Study: Advengers boosts Blue Star Ferries’ AI visibility with Writesonic

Advengers lifts Blue Star Ferries’ AI visibility 15% in 6 months with Writesonic

Advengers, a major Greek performance marketing agency, faced the challenge that its clients, including Blue Star Ferries, were invisible in AI search results, losing visibility to competitors as traveler and buyer behavior shifted to using AI tools like ChatGPT. To address their clients' fear and competitive disadvantage, Advengers utilized Writesonic's GEO (Generative Engine Optimization) service, including its Prompt Gap Analysis tool, to demonstrate the problem and build a solution roadmap.

Writesonic's solution involved a repeatable 3-step GEO process: a technical audit, prompt research, and authoritative content creation. For client Blue Star Ferries, this strategy resulted in a 15% lift in AI visibility and 100 new citations across 473 pages within six months. Crucially, the campaign led Blue Star Ferries to surpass its competitor, Hellenic Seaways, in first-brand-mention rate for Greek ferry queries, solidifying the success of the Writesonic-powered approach.
