RSS Auto Post Social Media: Step‑by‑Step Guide
Learn how to auto‑post your blog to Facebook, Instagram, X and LinkedIn with Flow’s RSS feature and boost reach instantly.
Flow lets you automatically share every new blog article to Facebook Pages, Instagram, X (text‑only) and LinkedIn Profile by simply adding your RSS feed – no manual copy‑pasting required.
What is RSS auto posting and why choose Flow?
RSS (Really Simple Syndication) feeds publish a stream of your latest posts in a standardized XML format. Flow reads that feed, formats each entry, and pushes it to the social accounts you select. This saves time, keeps your audience updated, and ensures consistent branding across platforms. Because Flow integrates AI caption generation (1 credit per post) and AI image creation (3 credits per post), you can enrich each auto‑post without extra effort.
How do I connect my blog’s RSS feed in Flow?
Follow these steps to set up the feed:
- Log into Flow and go to Dashboard > RSS Auto‑Post.
- Click Add New Feed and paste your blog’s RSS URL (e.g.,
https://example.com/feed). - Choose a name for the feed, then hit Save.
- In the feed details, toggle Enable Auto‑Posting and select the social profiles you want to publish to.
- Optionally set a Posting Schedule (e.g., immediate, or queue for later).
Once saved, Flow will check the feed every 15 minutes and create a post for each new article.
Which social platforms can receive RSS auto posts?
Flow supports four networks for RSS auto posting:
- Facebook Pages – full text, image, and link preview.
- Instagram – requires a connected Facebook Page and JPEG images (no carousel via RSS).
- X – text‑only; any image must be added manually or via AI image credit.
- LinkedIn Profile – standard post with link and optional image.
Note: LinkedIn Pages are not supported, and TikTok is excluded from the feature set.
How can I customize captions with Flow’s AI text generation?
When you enable AI Caption for a feed, Flow uses one credit per post to generate a concise, platform‑appropriate caption. To configure:
- Open the feed, click Caption Settings.
- Select Use AI Caption and set a tone (e.g., professional, casual).
- Enter any required keywords or hashtags; Flow will weave them into the generated text.
Example: For a blog about "remote work tools," you might get the caption "Discover the top remote‑work tools that boost productivity – link in bio! #remotework #productivity".
How do I add images using Flow’s AI image generation?
Each RSS auto post can include an AI‑generated image (3 credits per post). Set it up as follows:
- In the same feed screen, open Image Settings.
- Toggle Generate AI Image and choose a style (e.g., minimalist, vibrant).
- Provide a brief prompt, such as "a modern home office with a laptop and coffee".
- Save – Flow will create a JPEG that meets Instagram’s requirements and attach it to the post.
If you prefer to use the article’s featured image, disable AI generation and select Use Featured Image.
Can I schedule bulk posts and manage a content calendar?
Yes. Flow’s Content Calendar view shows all queued RSS posts across your selected networks. You can drag‑and‑drop items to reschedule, or set a default posting window (e.g., 9 am – 5 pm). Bulk posting works by:
- Enabling Bulk Mode in the feed settings.
- Choosing a time interval (hourly, daily) for the queue.
- Reviewing the generated queue in the Features page before it goes live.
This ensures a steady stream of content without overwhelming any single platform.
