Semi Authority Site Makes NO Money

I would forget about SEO and ranking cause the moment you do a good job with that,Google will spring another animal on you. I would concentrate on building a following with a list. Put an opt in form on your site and start going after subscribers, followers etc through list building....you know what they say...the money is in the list. I have had it with G. Good luck

That's the problem with traffic that's not already committed to a niche, social has a lot of window shoppers blazing through their social account looking at images & what their friends Like & refer them. I know this because I watch my family do these things (window shopping from social accounts).

Something like a targeted same niche forum has people that are already committed to the niche, otherwise they wouldn't have wasted time creating a niche profile. I'm talking about real people interested in the niche, not spammers blasting profiles.

Really those two things (forums & social) aren't SEO, it's direct traffic because both link types are some of the weakest links you can get. So listing those two link types is pretty much irrelevant why your pages aren't ranking, you can take that out of the equation & focus on what matters, good links from relevant domains.

You said in OP that the site is an authority, so don't you have some strong links from same/similar niche sites?

Are you promoting your domain on sites that matter? Your doing social but that's pretty much not doing anything from what you've posted here (no sales/clicks). Target strong same niche domain pages that will help push your own pages up the SERPs.

Don't get me wrong, multiple traffic sources are awesome but they need to either be promoting you to buyers or buying directly from you otherwise they're just fluff.
