About hrefStack
hrefStack is an autonomous content agent that runs the whole SEO publishing loop rather than assisting with one step of it. Connected to a CMS, a domain and Google Search Console, it scans existing content and technical setup, analyses competitors, finds keyword gaps, plans a calendar weeks ahead against seasonal trends and publishing cadence, writes publication-ready articles, and publishes them on schedule to WordPress, Webflow or a custom endpoint via API. The distinguishing mechanics are on the quality side: every piece is scored across six dimensions — relevance, depth, originality, readability, SEO compliance and citation-worthiness — before it goes live, and the agent self-audits for grammar, factual accuracy, SEO compliance and brand voice, fixing what it finds before anything reaches a review queue. After publication it keeps monitoring, tracking rankings and AI citations across Google, AI Overviews, ChatGPT and Perplexity, and automatically refreshing articles that decay. Generative-engine optimisation is treated as a first-class target rather than a bolt-on, with entity-rich structured content aimed at being cited by AI answer engines. Editorial control remains available at every stage — output can be reviewed, retoned or approved as-is — but the default mode is unattended. Plans are metered in words per month rather than article counts, with per-article word ceilings rising by tier.
