I would agree with you if you defined “trash” as a place that doesn’t produce much results if you just come in, drop a bunch of links, and leave.
If that's how you define trashy Facebook groups, you're absolutely correct!
But I still get a lot of traffic from Facebook groups because I invest in them.
I don’t invest money, but I invest time.
You have to understand that people join these groups for a reason.
And let me tell you: seeing unrelated ads or flat-out spam isn't in their list of reasons.
So if you are very discriminating as to the kinds of Facebook groups that you join, and they have some sort of process for vetting or screening new members, if you play by the rules, you will get a lot of highly qualified traffic that can lead to bigger newsletters.
I make my money through my newsletters, and this is the name of the game because whatever credibility the groups that they came from have carries over to the content that I share on those groups.
And when they find that similar on-topic niche-specific content in the updates I send, I maintain their trust.
At the end of the day, nobody’s going to buy from you if they don’t trust you.
So if you think that just blasting spam through Facebook groups is going to generate a ton of results, then I agree with you—it’s trash now.
But when used as intended, it can produce solid outcomes.
