As is often the case in webdev there is no one answer or magic solution. Especially as the real needed/wanted/desired solution is qualified traffic. In this context qualified traffic == traffic more likely to convert (define conversion as you will). Given EGOL's foundation of good content we are left with identifying, analysing, and optimising for potential traffic sources. And then marketing appropriately for each in turn.
This is not a step by step how-to (I have invested a lot of time and effort and even some cash into most of the following suggestions), rather a list of researchable actionable suggestions. The first thing to do is to thoroughly understand your business model and unique selling proposition(s)/point(s), market and market segmentation (behavioral, demographical, geographical, psychographical). Yes, know thyself.
Then decide how to differentiate traffic source and to what degree. Such a breakout might look something like:
* direct: type-in, bookmark.
Note: many analytics programs default classify any traffic for which they can not determine a source as direct traffic.
Note: some analytics programs default classify ppc traffic as direct traffic.
* search: Bing, Google, Yahoo et al
* directories: Yahoo, BOTW, JoeAnt, YellowPages, Yelp et al
Note: there are both free and paid directories/guides.
Note: which directories are best is vertical/niche/site dependent.
* social: MySpace, FaceBook, Twitter et al
* PPC (Pay Per Click), i.e. paid advertising: AdWords, adCenter, YellowPages et al
Note: I have never used PPC. There is a steep learning curve to do it right but the ROI can be significant. It can also be throwing money away.
* publish-republish elsewhere: guest blog, ezines, YouTube et al
Note: Many such third party sites were greatly impacted by Panda so care in selection is warranted.
* OPS (Other Peoples' Sites): last but not least the backbone of the web, all those delightfully discerning sites that link out to yours.
Let's walk back up that breakout in reverse order:
* OPS: here is where the foundation of 'good content' is perhaps most important. Why should another site link to one of your pages? There are two major link/traffic building approaches:
---build subject link magnets (the upscale version of link bait) optimised to of captivating interest and gold plated resource to your niche audience.
---research specific desirable sites and build subject matter that extends or compliments their offering(s).
Note: how you then offer/market your creations is your business.
* publish-republish elsewhere: there can be a significant difference in approach and offering depending on your site focus, i.e. personal service, ecommerce, information. As my experience lately has all been with an information focus I have retained most content for on site use only. I do, however, utilise YouTube (video), Flickr (images), Amazon (ebooks), Slideshare (presentations). I also appreciate Q&A sites such as Yahoo Answers and Quora, contributing to Wikipedia - much less time and attention required than 'standard' social media but with some of the aspects.
* PPC: not my thing. caveat emptor.
* social: the real trick is NOT to follow your competition but to follow your ((potential)(most) converting) visitors. And the kicker is to only go where and how you can be of value to those visitors. With social the how you engage/converse is critical. Have both strategic and tactical plans for each platform/application (they are each quite different) before you start and be willing and able to adjust as necessary. And be ready for the long haul, jumping in and then out is a waste of resources at best, a damage to your reputation at worst. It is far far better to have not engaged than to have done so poorly.
* directories: have seen the long decline from glory days of old reverse with the advent of Local search. A majority are still not worth utilising for a number of reasons, however, careful selection and use can be quite advantageous.
Note: I lump what some term 'guides' in with directories.
* search: not much to say here except that diversifying/expanding search traffic from one to several search engines is worth exploring.
* direct: the possibilities may vary somewhat depending on site and business model. One universal is to work at retaining visitors both to stay longer and to return, primarily through content design and architecture. A second is to build a solid, preferably remarkable, brand; when visitors think of your niche they should think of you.
Some direct traffic generators worth considering:
---as EGOL mentioned, RSS.
---email newsletters, aka mailing list
---downloads, i.e whitepapers, graphics/videos, apps, widgets...
---a blog to encourage conversation
---suggest/remind visitors to bookmark pages.
