Daily WordPress SEO Article Drafts with OpenAI + n8n

Generate daily WordPress SEO article drafts—automatically

This n8n workflow creates fully written WordPress draft posts using OpenAI: it generates SEO metadata, builds the article in HTML, and populates Rank Math SEO fields via the WordPress REST API—optionally pinging the Google Indexing API before finishing.

What this workflow does

• Runs on a schedule: executes every day at 09:00 using a cron trigger.
• Rotates through predefined targets: cycles through configured topics, focus keywords, and WordPress settings (site/audience/theme configuration and category/media IDs).
• Generates structured SEO metadata with OpenAI: produces an H1 title, meta description, slug, outline, tags, and an FAQ block.
• Writes the article body in HTML: uses the generated outline and internal-link rules, then merges intro, body, conclusion, and FAQ.
• Converts formatting and enhances content: cleans up markdown-like formatting into clean HTML, adds a “Leia também” section and a tag line.
• Creates the WordPress draft: posts content as a draft via /wp-json/wp/v2/posts, setting slug, category, and Rank Math focus keyword/title/description fields.
• Finishes the post: updates the featured image ID and, if enabled, sends the URL to the Google Indexing API.

Use cases

• SaaS teams that publish consistent SEO content to support organic growth.
• Automation engineers who want a hands-on example of OpenAI + WordPress REST for daily content pipelines.
• Marketing ops that need draft-ready posts with Rank Math SEO metadata prefilled.
