Auto-Post Your Blog to Social Media via RSS

You publish a blog post. Then you switch to Facebook to share it, to LinkedIn to share it again, to X with a shorter version. By the third platform the enthusiasm is gone, and half the time you skip it. Good content goes out once and never gets promoted.

RSS auto-posting fixes that. Connect your blog's feed once, and every new article can post itself to your social channels. Here's how it works and how to set it up.

What RSS auto-posting actually is

RSS is a plain, machine-readable list of everything your site publishes. Most blogs and CMS platforms generate one automatically. It contains each post's title, link, and summary, updated the moment you hit publish.

An RSS auto-poster watches that feed. When a new item shows up, it creates a social post from it and sends it to your connected channels on a schedule. You write the article; the promotion happens on its own.

Who needs this

• Bloggers and publishers who post regularly and forget to share every piece.
• SMBs with a news or updates section who want announcements to reach followers without extra steps.
• Agencies running social for clients who already publish content the client wants amplified.

If your website produces a steady stream of posts, this turns that stream into a social feed with no daily effort.

Step 1: find your feed URL

Most platforms expose a feed at a predictable address. Try these first:

• WordPress: add /feed/ to your domain, e.g. yoursite.com/feed/
• Blogger: yoursite.com/feeds/posts/default
• Medium: medium.com/feed/@yourusername
• Shopify blogs: yourstore.com/blogs/news.atom

Paste the address into a browser. If you see structured text with your recent post titles, that's your feed. If you're not sure, view your site's source and search for "rss" or "atom" to find the link. Copy the full URL.

Step 2: set up an RSS schedule in Flow

In Flow, create a new RSS schedule and paste your feed URL. Then configure a few things:

• Choose your channels. Pick where new items post: your Facebook Page, Instagram, X, or LinkedIn Profile. Keep in mind Instagram needs a JPEG image and X is text-only, so a link-heavy blog feed often fits Facebook and LinkedIn most naturally.
• Set the posting frequency. Decide how often Flow checks the feed and how often it's allowed to post. This keeps a burst of new articles from flooding your channels all at once.
• Confirm the format. Decide how each item appears, using the post title and link pulled from the feed as the starting point.

Once it's active, Flow handles the rest. New articles enter your queue and publish on the cadence you set.

Step 3: layer AI captions on your feed items

A raw feed item is functional but flat, often just a title and a link. You can do better by letting AI write a proper caption for each one.

Instead of posting the bare headline, use Flow's AI text generation to turn it into a short, natural intro that gives people a reason to click. AI text costs 1 credit per generation, so a handful of credits covers a week of articles.

Good caption instructions for feed items:

• Ask for a one or two sentence hook that summarizes the value, not just the title repeated.
• Specify tone so LinkedIn reads more professional and Facebook reads more casual.
• Request a relevant hashtag or two, but keep it restrained.

The point is that each channel gets copy written for its audience instead of the same recycled headline everywhere.

Frequency and queue best practices

Automation is only helpful if it doesn't annoy your followers. A few rules keep it clean:

• Don't post everything instantly. If you publish five posts in a day, spacing them out over several days keeps your feed from looking like a dump.
• Mind the gap between platforms. The same link on Facebook and LinkedIn within the same minute looks automated. A small offset feels more human.
• Keep evergreen and new separate. Use the RSS schedule for fresh posts, and your regular content calendar for the rest, so your feed isn't all blog links.
• Check the queue weekly. Open the calendar, see what's lined up, and pause or edit anything that doesn't fit. Automation runs best with a light hand on it.

A realistic setup

Here's a workflow that holds up: connect your WordPress /feed/ URL, point it at your Facebook Page and LinkedIn Profile, set a modest frequency so no more than a post or two goes out per day, and enable AI captions tuned per channel. Now every article you write announces itself, twice, in copy that actually reads well. You keep writing; the promotion takes care of itself.

Turn your feed into a social pipeline

RSS auto-posting is available across Flow's plans, and the free tier lets you try it with Facebook and Instagram before you add more channels. See the full list on the features page, or compare what each tier unlocks on pricing. Paid plans include a 7-day money-back guarantee.

Stop sharing every post by hand. Start free, connect your feed, and let new articles post themselves.
