Platform Overview

RankHub is an SEO autopilot that researches keywords, generates optimized blog articles, and publishes them to your website automatically. The entire pipeline runs on a monthly cycle — from keyword selection to final delivery via webhook.

End-to-End Pipeline

2Content Calendar

3Headline Generation

4Your Approval

5Draft Generation

6Publish & Deliver

Each delivery includes the article title, slug, HTML and markdown content, featured image, SEO metadata, and tags. Your endpoint verifies the request using a Bearer token, then creates the blog post in your CMS or database.

You stay in control with headline approval before any content is generated. RankHub handles the research, writing, image generation, and delivery — you approve what gets published.

How Autopilot Works

The autopilot runs on a monthly cycle. Ten days before each month ends, RankHub automatically generates the next month's content calendar, selects keywords from your pool, and creates headlines for approval.

Calendar Generation

RankHub creates a content calendar based on your subscription tier. Posts are spread evenly across the month on your preferred publish day.

10 days before month end

Headline Generation

AI generates SEO-optimized headlines for each scheduled post using keywords from your pool. Article types are automatically selected based on search intent.

Immediately after calendar

Your Approval

You receive an email with all headlines for the month. Select which to approve, reject, or skip. You have 5 days to respond.

5-day approval window

Draft Generation

Approved posts are queued for generation. RankHub writes the full article, generates a featured image, adds internal links, and formats the HTML.

1 day before scheduled publish

Publishing & Delivery

On the scheduled date, RankHub runs a semantic similarity check to prevent duplicate content, then delivers the article to your webhook endpoint.

Hourly publishing checks

Semantic Safety Check

Before publishing, RankHub compares each article against your existing content using vector embeddings. Articles with >90% similarity to published content are flagged for review instead of auto-publishing.

Content Calendar

Each month, RankHub generates a content calendar that schedules posts evenly across the month. The number of posts depends on your subscription tier.

Tier	Posts/Month	Frequency
Starter	4	Every 7 days
Growth	15	Every 2 days
Scale	30	Daily

You can configure your preferred publish day (Monday through Sunday) in website settings. Posts are scheduled starting from your preferred day and spread evenly across the month.

Calendars are generated 10 days before each month ends, giving you time to review and approve headlines before the new month begins.

Headline Approval

After headlines are generated, you receive an email with a secure approval link. The approval page shows each headline with its target keyword, search intent, scheduled date, and rationale.

Approval Workflow

RankHub sends an email with your monthly headlines
Click the secure approval link (valid for 5 days)
Review each headline — select or deselect individually
Submit your selections
Approved headlines are queued for draft generation

Approved

Queued for draft generation 1 day before the scheduled publish date.

Rejected

Skipped for this month. The keyword returns to the pool.

Expired

No response within 5 days. Headlines are not generated.

Auto-Approval

Enable auto-approval in your content calendar settings to skip the email step. All generated headlines are automatically approved and queued for generation. Best for high-trust editorial workflows.

Article Types

RankHub automatically selects the best article type for each keyword based on search intent. Ten article types cover informational and commercial content.

Type	Pattern	Intent
HOW_TO Step-by-step tutorials and guides	How to [Goal] with [Method]	Informational
LISTICLE Numbered lists, easy to scan	[N] Ways/Tips to [Goal]	Informational

HTTP Headers

Header	Value	Description
Content-Type	application/json	Always JSON. Parse the request body as JSON.
Authorization	Bearer <your_auth_token>	Bearer token set in your webhook configuration. Compare with your stored token to authenticate.
X-RankHub-Delivery-Id	<unique_delivery_id>	Unique identifier for this delivery attempt. Useful for deduplication and debugging.

Allowed HTML Tags

The content_html field only contains these semantic HTML tags. Any h1 tags are automatically converted to h2.

Rich components use rh-* prefixed CSS classes (e.g., rh-callout, rh-comparison, rh-stat, rh-data-bar).

Styling Rich Components

Choose one of two stylesheets. Both require wrapping your article in class="blog-prose".

Option 1: Full design (plug-and-play)

Includes layout + colors, fonts, and backgrounds. Use the css_url payload field or:

<link rel="stylesheet" href="https://rankhub.ai/api/blog-spec/styles.css" />

Option 2: Structural only (bring your own design)

Layout only (grid, flex, spacing) — no colors or fonts. Apply your own brand styles on top. Use the css_base_url payload field or:

<link rel="stylesheet" href="https://rankhub.ai/api/blog-spec/styles-base.css" />

HTTP Headers

Every webhook delivery includes the following HTTP headers. Use these to authenticate the request.

Content-Type

Always application/json. Parse the request body as JSON.

Authorization

Bearer token from your webhook settings. Format: Bearer <your_auth_token>. Compare against your stored token to authenticate.

X-RankHub-Delivery-Id

Unique identifier for this delivery attempt. Useful for deduplication and debugging. If you receive the same delivery ID twice, it means a retry occurred.

Authentication

RankHub uses Bearer token authentication. When you set up your webhook in the Settings → Connections page, you provide an auth token. RankHub includes this token in the Authorization header of every delivery.

Your endpoint should extract the token from the header, strip the Bearer prefix, and compare it against your stored token. If the tokens don't match, return a 401 Unauthorized response.

Code Examples

Complete webhook handler examples with Bearer token verification. Choose your language below.

const express = require('express')
const app = express()

app.post('/api/webhook/rankhub', express.json(), (req, res) => {
  // 1. Verify Bearer token
  const token = req.headers.authorization?.replace('Bearer ', '')
  if (token !== process.env.RANKHUB_AUTH_TOKEN) {
    return res.status(401).json({ error: 'Unauthorized' })
  }

  // 2. Use the payload
  const { title, slug, content_html, content_markdown,
          meta_description, image_url, css_url, tags } = req.body
  // 3. Render content_html inside <div class="blog-prose">
  // and add <link rel="stylesheet" href={css_url} /> to your blog layout
  // Create your blog post here...

  res.status(200).json({ received: true })
})

Note: Adapt the path to your framework. Next.js App Router: app/api/webhook/rankhub/route.js. The path must match the URL configured in your RankHub webhook settings.

Retry Behavior

RankHub automatically retries failed deliveries to ensure your content arrives. The retry policy depends on the HTTP status code your endpoint returns.

Response	Behavior
200-299	Delivery successful. No further action.
429	Rate limited. Retried up to 5 times with exponential backoff.
5xx	Server error. Retried up to 5 times with exponential backoff.
4xx (except 429)	Client error. Not retried. Fix your endpoint configuration.

Backoff Schedule

#11 min

#25 min

#315 min

#430 min

#530 min

Each delay includes +/-10% jitter. Total retry window: approximately 51 minutes. After all retries are exhausted, you receive an in-app notification.

Styling Your Blog

RankHub articles include rich components (callouts, comparison tables, stat highlights, and more) that use rh-* CSS classes. Add one of the stylesheets below and wrap your article in class="blog-prose" to render them correctly.

Option A: Full Design

Layout + colors, fonts, and backgrounds. Works out of the box.

<link rel="stylesheet"
  href="https://rankhub.ai/api/blog-spec/styles.css" />

Option B: Structural Only

Layout only. Add your own brand colors and fonts on top.

<link rel="stylesheet"
  href="https://rankhub.ai/api/blog-spec/styles-base.css" />

Webhook Payload Fields

Each delivery includes css_url (full design) and css_base_url (structural only) so you can load the stylesheet dynamically instead of hardcoding the URL.
