The Problem
- Manual publishing process per piece: WordPress 30–45 min (copy-paste HTML, upload image separately, format, preview, publish) + LinkedIn company 15 min + LinkedIn personal 15 min + Twitter 10 min + sheet update 5 min = 75–90 minutes per content piece.
- For 20 pieces/month: 25–30 hours of manual publishing = $2,250/month ($27,000/year) in marketing manager time.
- In practice only 12 of 20 pieces were published — 8 sat stuck in pending.
- 3–5 mistakes per month: wrong featured image, missed platform, missing hashtags.
- Content waited 3–5 days after approval before going live.
The Solution
Scheduled n8n workflow triggering daily at 9AM.
- Reads 'BrainLink' Google Sheet, filters rows where APPROVEDDATE is set AND PublishedDate is empty.
- Downloads HTML blog content from Google Drive link (supports multi-stakeholder editing before approval).
03Creates WordPress post via REST API with title, content, status
- 'publish'.
- Downloads featured image from Google Drive as binary data (direct Drive links cannot be used as WP media).
- Uploads image to WordPress as media with content-disposition header.
- Sets featured image on post via `POST /wp-json/wp/v2/posts/{id}` with mediaId.
07Updates Google Sheet
- clears APPROVEDDATE to prevent re-processing, sets PublishedDate.
08LinkedIn conditional
- if LinkedinContent column has content, posts to company page (org ID '140281') and personal profile ('bvylyeIT_3') with image — `onError: continueErrorOutput` so LinkedIn failure doesn't block Twitter.
09Twitter conditional
- if TweetContent column has content, posts tweet with image.
- Instagram placeholder node for future integration.
