fundamental ways in internet marketing

Quick story first:
A few years ago, before getting into IM, I was at a conference in silicon valley where the panel was a bunch of user experience designers. During the Q and A session, someone asked the panel what they thought the web would be like in five years. The guy from Yahoo jumps in and says "everything will change. everything." and rants for a awhile about this. He seemed pretty confident so. Then the guy from Adobe simply says, "But all the fundamentals will stay the same."

I think this is completely true in IM as well. Since you have had a lot of success in the past, then you probably have an excellent handle on the fundamentals of things like building lists. Once they are in your funnel, you're good to go.

So I would say that picking a good niche and getting a funnel going should be your priority. Then next question is how to get traffic, and that's what keeps changing. Unfortunately these either take time or they take money.

Good old SEO (pick a keyword, make a page, build links until you're #1) is still around and I don't see it going anywhere soon despite panda type updates, but you will need to build links differently than in 2003. (Sounds like you already know this )

You can also try content marketing for traffic; creating for your niche really top notch articles, videos, pdfs, etc with intention of bringing traffic to a squeeze page. Because everything has gone social if you put out some good content in your niche and make it easy to share, you will see a steady stream of subscribers to your list.

PPC is still around too but you can do it on Facebook now too. Facebook has potential because rather than target keywords, you target very specific demographics, like "men over 30 who like to eat hot dogs in Cleveland while watching Entourage" Given your situation, I'd say wait on paid traffic until you get some revenue elsewhere.

Bottom-line: I totally get that you like having a diversity of strategies in the pan. I'm the same way, and I like it because experimenting is always good and keeps things fun. But in your situation, you can't afford that until you pick the most promising strategy, put in those crazy hours for the next month and get some results.
