IM/SEO Overload!..What's the SIMPLE Formula?

Fellow Warriors, I'm experiencing too much SEO complication, looking for streamlined approach. Here's my dilemma:

I've been putting up affiliate sites for about 3 years now. I've learned a lot, the sites have gotten better, the niches/KWs are better chosen, and I've had some medium-to-good rankings for certain pages/KWs. I've tried various approaches to get top traffic/rankings and I'm not a "newbie."

However, I still experience the process of SEO to be too complicated, requiring too many multi-attack approaches to guarantee success, and devoid of a simple, streamlined formula.

Then I get 50 emails every day from marketers telling me if I really want my SEO efforts to work, I've simply got to get their new, shiny course or auto-backlinking plugin, or check out today's "WSO of the millenium," which also tells me I've been doing it all wrong and I just gotta get the next magic backlinking machine.

Maybe the multi-strategy approach is a necessary evil of organic SEO, and you simply have to do a Nuke campaign + do lots of blog commenting to high PRblogs + use Scrapebox + make sure you're running good Twitter & Facebook campaigns + grab some .edu and .gov links from Angie or Paul + run some Xrumer forum profiles + run a digi-auto-backlink-creator plugin from your WP dashboard + JV-up with a bunch of these WSO sales + make sure you're building your list + + +....aaugghhh! You get the picture.

And perhaps if you're not willing do juggle all those tasks (even with an outsourcer, it's a LOT!) then perhaps you just don't belong in IM. Fair enough. But I keep hoping for one streamlined formula with just a few simple repeated tasks, that works so consistently that I can just do that over & over, not feel overwhelmed, and unsubscribe to ALL the latest offers and how-to courses.

Your thoughts are welcome, thanks.
