Agents running SEO for two weeks: 8 draft PRs, most runs under $1

Pitiful-Surround-285 · reddit · 2026-09-02

The author shares a two-week experiment automating SEO content with agents, built for reliability without babysitting at manageable cost.

Setup: A writer agent does keyword research and drafting, briefing a second media agent for figures/images mid-run; they hand off in a shared workspace. A single markdown skill file holds the run protocol, keyword rules, and writing guidelines. Site specifics (domain, repo, topic lanes, voice) live in a separate prompt attached to a scheduled headless run.

Per run: pull keyword candidates from DataForSEO (volume/difficulty/CPC), pick one, read current ranking pages, draft, brief the media agent, open a draft PR on a seo/<slug> branch, email the link. A human merges or nothing ships. All you need is a blog repo and a DataForSEO account.

Numbers: 8 draft PRs in two weeks (1 merged, 1 closed, rest in review); most runs under $1 including images.

Key insight: the prompt mattered more than the model. Their blog is TSX components in a Vite React app that must pass bun run build — once the prompt encoded the repo layout, the three files per post, and style bans, drafts arrived mergeable. The writer doesn't need the biggest model when the method lives in the skill file and a human gate catches what slips through.
