- Open Instagram and go to your profile.
- Tap the menu (☰) in the top right corner.
- Select Settings and privacy.
- Scroll to Account Center.
- Tap Accounts & profiles.
- Add your Facebook profile or page.
- Grant permissions when prompted.
> Pro Tip: Always confirm you’re logged into the correct Facebook account to avoid posting to the wrong profile or page.

Customizing Captions for Instagram and Facebook
While the media may be the same, captions can be tailored for each platform’s audience.
Best Practices:
- Adapt tone: Short and trendy for Instagram; longer and detailed for Facebook.
- Tag strategically: Use platform-specific usernames or Page names.
- Hashtags: More effective on Instagram, limit to 1–3 on Facebook.

Choosing When to Post Selectively
Sometimes cross-posting isn’t ideal:

Selective posting allows you to tailor messaging for audience preferences.
