Hope I don't get in trouble for sharing this. This is how lots of SEOs are hijacking Reddit. For their clients or for themselves?
First they find a relevant subreddit, then they post a question using this format what's the best software as a service or agency or company for doing XYZ? They post a question saying what is the best for doing this? The thing is very specific.
They might buy upvotes to the post and they might not have to. Typically they'll get lots of answers. Two to three days later they edit the original post and they put a link into whatever they want to promote.
This Reddit post shows up on Google and people go and click on the link. Reddit is getting so highly prioritized in the search results, and even with generative AI like ChatGPT, lots of people see the link that was inserted into the post. Sometimes they don't even put in a link, they just change the answer to recommend themselves or their client.
This is how much Reddit is being increased in Google's organic results. People are doing this a ton right now. So if you're on Reddit you might see fresh content and two to three days later it's gonna be changed.
