Single Grain

Single Grain is a Los Angeles-based digital marketing agency with a strong SEO and content practice, founded by Eric Siu, who has built a significant audience in the marketing community through his podcast and content output. Their SEO work covers keyword strategy, technical site health, content production for organic, and link building, positioned within a full-funnel digital marketing offering that also spans paid acquisition, CRO, and video content. The breadth of their service means SEO and paid inform each other rather than operating as separate briefs.

Their approach to SEO draws on the same analytical and experimental culture that runs through their paid work: test what works, measure outcomes against pipeline rather than traffic, and iterate faster than the competition. Content is produced to serve both organic rankings and conversion, with messaging and intent alignment informed by what paid campaigns have learned about buyer behavior. This connected approach reduces the time it takes to understand which organic topics and formats generate pipeline for a specific SaaS product.

Single Grain is a good fit for B2B SaaS companies that want SEO run inside a broader performance marketing framework with cross-channel data informing organic strategy. They suit growth-stage companies that want a full-service partner rather than a specialist agency focused exclusively on organic. They are less suited to companies that need a dedicated technical SEO partner with deep site architecture expertise, or to those looking for a content-first organic approach independent of the paid and CRO context Single Grain brings.

Content at Single Grain serves a full-funnel marketing strategy rather than operating as a standalone channel. Their content team produces pieces informed by what paid campaigns are learning about buyer intent, which means editorial direction is shaped by real conversion data rather than keyword volume alone. This integration prevents the common situation where content and paid teams work from different audience assumptions and produce inconsistent messaging across channels.

Their content output spans long-form SEO articles, landing pages optimized for conversion, and video content for paid and organic social, which reflects their broader multi-channel model. The analytical culture that runs through their paid work applies to content measurement: pieces are evaluated against qualified traffic and conversion contribution rather than engagement metrics, and under-performing content is updated or replaced rather than left to accumulate on the site. This active content management approach maintains the quality and commercial relevance of the program over time.

Single Grain is a good fit for B2B SaaS companies that want content produced as part of a performance marketing system where editorial output is continuously refined based on what the data says is working. They suit companies that value speed and iteration over a fixed editorial calendar. They are less suited to companies looking for a premium thought leadership partner producing original research and long-form category authority content, or to those that want content managed independently of paid and performance channels.
