Sabrina Armstrong is Director of Sales at Victorious, the San Francisco, California, SEO and answer engine optimization agency founded by Michael Transon. A sales leader who came up through web strategy consulting, she spent nearly eight years at WebFX and ran sales at Single Grain before joining Victorious.
Eight Years at WebFX
Armstrong earned a bachelor's degree at Drexel University. She then spent nearly eight years at WebFX, the Harrisburg, Pennsylvania, digital marketing agency, where her LinkedIn profile shows a path from web strategy specialist and senior web strategy consultant to senior team lead and, from 2024, director of sales.
When she left in April 2025 she wrote that WebFX "was where I grew, stretched, and sharpened my skills alongside some of the smartest, kindest people I've ever worked with."
Leading Sales at Single Grain
That April she became head of sales at Single Grain, the Los Angeles, California, agency led by Eric Siu. In her LinkedIn announcement she thanked Siu and CTO Shaun Merritt, among others, for trusting her to lead sales during a period of growth, and pointed companies to Karrot, Single Grain's AI tool for targeted LinkedIn ad campaigns. "I'm fired up to build, grow, and serve in this next role," she wrote. She held the job until January 2026.
Leading Sales at Victorious
Her author page on the Victorious site says her years advising clients on turning search performance into inbound leads and revenue shape how she sells, and that she brings a consultative approach to each prospective client, helping them understand what lasting search success looks like and how to get there.
She also writes guides for the Victorious blog aimed at companies deciding how to hire help with search, including pieces on writing an SEO request for proposal, choosing between an agency and an in-house team, and the benefits of enterprise SEO.
