Why POSSE Matters

The Problem with Platform-First Publishing

Consider what happens when you publish only on third-party platforms:

Risk	Impact
Platform shuts down	Total content loss
Account suspension	Immediate access removal
Algorithm changes	Reduced visibility
Terms of service changes	Forced content modification
Platform pivot	Feature removal

“If you’re not paying for the product, you are the product.”

— Common tech industry saying

A broken chain symbolizing broken links when platforms die Platforms come and go, but your domain persists.

The Benefits of Owning Your Content

When you own your content:

Permanence — Your URLs never break¹
Control — You decide the format and presentation
Portability — Easy migration to new platforms
SEO — Search engines index your site
Monetization — You control the revenue

The Core Principles

1. Canonical URLs

Your site is the canonical source. All syndicated copies should link back:

<!-- On your site -->
<link rel="canonical" href="https://yourblog.com/posts/my-article" />

<!-- Syndicated copies should reference your original -->

2. Microformats for Machine Readability

Microformats make your content parseable by IndieWeb tools:

<article class="h-entry">
  <h1 class="p-name">Article Title</h1>
  <time class="dt-published" datetime="2024-03-01">March 1, 2024</time>
  <div class="e-content">
    <!-- Your content here -->
  </div>
  <a class="u-url" href="/posts/my-article">Permalink</a>
</article>

3. Syndication Links

After syndicating, update your post with u-syndication links:

<p>Also published on:
  <a class="u-syndication" rel="syndication" href="https://twitter.com/...">Twitter</a>,
  <a class="u-syndication" rel="syndication" href="https://mastodon.social/...">Mastodon</a>
</p>

Technical Implementation

RSS Feed Structure

A well-structured RSS feed is essential for automation:

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">
  <channel>
    <title>Your Blog</title>
    <link>https://yourblog.com</link>
    <description>Your blog description</description>
    <atom:link href="https://yourblog.com/rss.xml" rel="self"/>

    <item>
      <title>Post Title</title>
      <link>https://yourblog.com/posts/example</link>
      <guid>https://yourblog.com/posts/example</guid>
      <pubDate>Fri, 01 Mar 2024 00:00:00 GMT</pubDate>
      <description>Post excerpt...</description>
      <category>Technology</category>
      <category>IndieWeb</category>
    </item>
  </channel>
</rss>

Frontmatter Schema

Here’s the complete frontmatter schema this blog uses:

---
title: "Your Post Title"
description: "A compelling description for SEO and social cards"
pubDate: 2024-03-01
updatedDate: 2024-03-15  # Optional
tags: ["Tag1", "Tag2"]
heroImage: "/images/hero.jpg"  # Optional
heroImageAlt: "Description of the image"  # Required if heroImage set
draft: false  # Set true to hide from listings
syndication:  # Add URLs after cross-posting
  - https://twitter.com/you/status/12345
  - https://mastodon.social/@you/67890
author: "Override Author"  # Optional
---

Automation Tools

IFTTT (If This Then That)

Basic automation for beginners:

Trigger	Action
New RSS item	Post to Twitter
New RSS item	Post to Facebook
New RSS item	Send to Buffer

Pros: Easy setup, free tier available Cons: Limited customization, delays

Zapier

More powerful automation:

Trigger: RSS Feed → New Item
Action 1: Format text with title + URL
Action 2: Post to Twitter
Action 3: Post to LinkedIn
Action 4: Add to Notion database

Bridgy

Custom Scripts

For maximum control, write your own:

#!/usr/bin/env python3
"""
POSSE Syndication Script
Reads RSS feed, posts new items to configured platforms
"""

import feedparser
import tweepy
from mastodon import Mastodon

def syndicate_to_twitter(title, url):
    """Post to Twitter/X with proper formatting"""
    tweet = f"New post: {title}\n\n{url}"
    # ... Twitter API code

def syndicate_to_mastodon(title, url, tags):
    """Post to Mastodon with hashtags"""
    hashtags = " ".join(f"#{tag}" for tag in tags)
    toot = f"{title}\n\n{url}\n\n{hashtags}"
    # ... Mastodon API code

if __name__ == "__main__":
    feed = feedparser.parse("https://yourblog.com/rss.xml")
    for entry in feed.entries[:1]:  # Latest post
        syndicate_to_twitter(entry.title, entry.link)
        syndicate_to_mastodon(entry.title, entry.link, entry.tags)

Practical Examples

Example 1: Blog Post → Twitter Thread

Original post: 1500 words on your blog

Twitter version:

🧵 Thread: The Complete Guide to POSSE

POSSE = Publish on your Own Site, Syndicate Elsewhere

Here’s why every content creator should adopt this strategy…

Key points summarized in tweet-sized chunks, with a link to the full article.

Example 2: Photo Post

Your site shows the full-resolution image with EXIF data and your commentary.

Syndicated versions:

Instagram: Square crop, hashtags
Flickr: Full resolution, Creative Commons license
Twitter: Compressed, alt text

Example 3: Video Content

Example Video - How POSSE Works

Note: Embed your own videos hosted on your site, then syndicate to YouTube, Vimeo, etc.

Common Challenges

Challenge 1: Character Limits

Different platforms have different limits:

Platform	Limit	Strategy
Twitter/X	280 chars	Thread or summary + link
Mastodon	500 chars	Extended summary
LinkedIn	3000 chars	Full excerpt
Facebook	63,206 chars	Near-complete post

Challenge 2: Media Handling

Recommended image sizes:

Blog: 1200×630 (Open Graph standard)
Twitter: 1200×675 (1.91:1)
Instagram: 1080×1080 (1:1)
Pinterest: 1000×1500 (2:3)

Challenge 3: Engagement Fragmentation

When people comment on syndicated copies, those comments are scattered. Solutions:

Webmentions — Collect mentions back to your site
Bridgy — Pull social interactions to your site
Manual curation — Periodically copy notable comments

Checklist for Implementation

Set up your own website/blog
Configure RSS feed generation
Add microformats (h-entry, h-card)
Create accounts on syndication targets
Set up automation (IFTTT, Zapier, or custom)
Add syndication frontmatter field
Test the full workflow
Consider Webmentions for backlinks

Conclusion

POSSE isn’t just a technical strategy—it’s a philosophy of digital ownership. In a world where platforms extract value from your content, publishing on your own site first ensures that:

Your words remain yours. Your URLs persist. Your audience can always find you.

Start small: set up a blog, configure RSS, pick one syndication target. Grow from there.

Text Wrapping Around Images

Float Left Example: This paragraph demonstrates text wrapping around an image floated to the left. The image stays on the left side while the text flows naturally around it on the right. This is particularly useful for author photos, small illustrations, or any visual element that complements the text without interrupting the reading flow.

When you have enough text, it will continue to wrap around the floated image until it clears the bottom of the image. After that point, the text returns to its normal full-width layout. This creates a magazine-style layout that feels professional and polished.

Float Right Example: Similarly, you can float images to the right. This text wraps around the image on its left side. Right-floating images work well for pull quotes, diagrams, or supplementary visuals that enhance your content.

The key to effective image floating is having enough surrounding text. Short paragraphs may not wrap effectively, leaving awkward gaps. Aim for at least 3-4 sentences of text alongside floated images for the best visual result.

Notice how the layout adapts: on mobile devices, these floated images will stack normally (no float) to ensure readability on smaller screens.
