It took me a while to figure this out and I thought folks here might find it useful:
TL;DR: You can automatically create social media posts from specific Hugo blog posts using tags, RSS, and either IFTTT or Make.com. Just point the automation to the tag-specific RSS link: https://yourwebsite.com/tags/yourtag/index.xml
Here is my personal blog post on the process (which was also used to test the IFTTT integration to post on my LI):

(Full disclosure, I did need to clean up the LI post a bit manually after it posted, but I think with a bit of work this could become a cool way to automate social re-sharing of my Hugo posts.)
As I wrote on my site, this seemed super easy, then became much harder than expected when I realized I didn’t want to automatically share every single blog post, then easy again when I realized Hugo builds unique RSS feeds for each tag, then hard again when I actually saw the resulting LI post was formatted weird…
Does anyone have a similar workflow? I would be excited to learn what others are doing in the realm of social media automation for Hugo sites.
