I've seen autoblogging that works using social media content.
Basically, you take content from one platform that doesn't appear in Google search results because it's behind a log-in wall and properly SEO it to get decent traffic.
Of course, the key here is volume.
You can't just expect to find a trending post on social media, republish it, and hit the jackpot.
It normally doesn't work that way.
Chances are, somebody else has already republished it.
The key is finding something that's a little under the radar but has an intense following.
The intensity of the following and the organic community built around that type of content indicates that people search for it using search engines.
Another way you can do auto blogging is through auto video blogging.
Basically, there are tons of interesting Reddit stories, testimonials, case studies, and whathaveyou that people automatically convert into TikTok videos.
You probably have come across these.
Some of them can be annoying because the videos are just so off-topic that even though the audio is quite compelling, the whole package is somewhat off-putting.
To pull this off, you probably would need to spend a little bit more time cherry-picking your videos more carefully.
But the way this is done is you run a scraper on certain subreddits or certain Twitter feeds with links and then scrape the content.
Or, in the case of links, load the link into a browser, scrape the content, and then edit that down into video scripts.
Feed the video script into a text-to-speech software, choosing among various accents.
And from there, you can use a script to match the automated scraping of a video from free stock video sites.
You probably would need custom software for this, but it's well worth it because of the volume for such a system.
But yes, I've seen this play out.
Also, some derivatives are produced by autoblogging: Pinterest content, tweets, and even Quora answers, you name it...
The key is really just focusing on the right niche and then processing the content in such a way that it has a good chance of actually delivering value to the lives of your intended audience.
