n8n Workflow: Generate SEO Articles with OpenAI + IndexNow

Publish long-form developer SEO articles with OpenAI—then get them indexed fast via IndexNow

This n8n workflow automatically generates structured SEO articles using the OpenAI Chat Completions API, publishes them to sunoapi.top, and pings IndexNow for near-instant search engine indexing—on a 2-day schedule or on-demand through a webhook.

What this workflow does

• Runs on schedule or on demand: executes every 2 days, or accepts an external trigger via a webhook (POST /sunoapi-generate-content).
• Selects the topic and slug: uses a predefined Suno API keyword/topic (or accepts webhook-provided overrides) and prepares an article brief and target URL slug.
• Generates SEO content with OpenAI: calls the OpenAI Chat Completions API to produce a structured JSON output including markdown content and FAQs.
• Builds SEO metadata + schemas: parses the AI output, computes word count, and generates Schema.org JSON-LD for:
  • TechArticle
  • FAQPage
  • BreadcrumbList
• Publishes to sunoapi.top: sends the article payload (content, metadata, and schemas) to https://sunoapi.top/api/blog/publish after basic quality checks.
• IndexNow submission: transmits the published URL to the IndexNow API and returns a JSON status response to the webhook caller.

Use cases

• SaaS teams that need consistent developer SEO content without manual writing and publishing.
• Automation engineers building a repeatable pipeline from AI generation to CMS publication.
• Operators managing blog velocity and search discoverability with IndexNow.

Technical details

• Nodes used: if, code, webhook, sticky note, http request, schedule trigger.
• Integrations: OpenAI Chat Completions API, sunoapi.top blog publishing endpoint, IndexNow API.
