This is a hot topic near and dear to my heart.
I create a site 4 years ago that I've been writing on every since... there are probably near 2000 articles on it. Everything from fixing your MTU settings on your Q1000 modem to Java framework tips I find handy to years worth of game and movies reviews to hilarious cat pictures.
It's just anything and everything I've ever found interesting written in a slightly more professional manner than "stream of thought" with a small amount of attention paid to titles and internal links only when appropriate and valuable (I HATE how sites like Engadget inner-link every keyword for Google sake).
My understanding was always that "If I wrote it, they will come".
4 years later and that's not the case at all... I seem to be hitting a goddamn glass ceiling that I cannot figure out for the life of me why it exists or who is imposing it and I want to scream.
This topic on Reddit recently:

Got my ire up... then combined with typical junk search results I see on Google in any given day for a legit topic I'm searching for and I'm coming to the conclusion that you just can't win online unless you are an SEO-douchebag.
When was the last time you searched for something technical and found a CNET link and headed over only to notice it's a landing page that says "We didn't review this BUT we reviewed..." and has 97 links to other things on the site?
What the fuck.
Is this the only way to succeed now with this content diarrhea mill that is the web?
Why should Google pick your review for e.g. Scott Pilgrim over every other review on the Internet? Is it better written? Who will attest to that? Is it from a better brand than Rotten Tomatoes or a more trusted voice than Roger Ebert? Is it better designed? Does it have a voice or perspective that speaks to an audience which Rotten Tomatoes and Ebert tragically ignore? If it does, why aren't people mentioning so?
Go down the line for everything else you do: is this the best cat picture on the Internet? What attests to that? Is this the best Java framework tips on the Internet? What attests to that?
More broadly, is there a market niche for someone who is a bit of a Java programmer, a bit of a film critic, and a bit of a cat photographer, and will it support you against the competition from people who make it their mission in life to do funny cat photos?
Also, is it a good idea to get into these particular niches? LOLcats are are commodity business: any idiot can make them, many do. Reviews are a commodity business unless you are Roger Ebert: I can't name another reviewer in the entire world, and if you randomly pulled sentences from your review and the 15 other reviews of Scott Pilgrim that I read because I have far too much free time, I think it is highly unlikely that I will be able to identify your review. Or anyone else's, except Ebert.
Java programming tips are, potentially, not a commodity business. You could either go StackOverflow (community, comprehensiveness, etc are value adds) or you could go Subject Domain Expert For Japanese Entrance Examination File Formats in Java. But, at the other end of the scale, "opinions about the new Java release from someone who is not Knuth, Gosling, or Alan Turing back from the dead" is a commodity business.
Commodity businesses are bad places to be if you want quality to win out, because minute differentiations in quality are essentially unimportant in commodity businesses. There are many, many IP-based businesses where minute differentiations in quality mean 100x differences in returns. If you like quality, you probably want to be in one of those instead.
"If I wrote it, they will come" is not a marketing strategy.
