How many sources of getting traffic?

Everyone is using different ways to grow his/her traffic for their products, websites , blogs, etc. I want to know your point of view about How many sources you use getting traffic?

In most cases I stick with two primary ways of getting traffic - whichever ways are most efficient and most effective for me.

For example, if I am promoting an information based authority site/blog where the site shares information about a specific topic, then I will typically promote it using SEO and referrals. So most of the traffic comes from Google. The rest of the traffic usually comes from a wide variety of websites such as Facebook, Twitter, guest blog posts, white hat links earned from other sources (usually blogs and forums) or links from whatever forums I promoted the site on. With Google, the traffic will be concentrated mostly on a handful of shorter keywords along with a large number of long tail phrases associated with those shorter keywords.

So even though I am focused on getting traffic using 2 methods, the traffic usually comes from a wide variety of other sources. Most of the traffic will come from one source, usually Google organic search. And then the rest is trickle traffic from a wide variety of sources.

If I am promoting a business, I typically use a combination of SEO and PPC (usually Google Adwords). In that case, the vast majority of the traffic comes from Google. If that works well, I typically won't use other methods. If it doesn't work well, I will explore other options like banner advertising on relevant websites or content marketing of some kind or a combination of content marketing with Facebook ads or whatever else I can come up with for that situation. Most of the time though, the SEO and PPC work very well.

Agreed with @PTTed

The type of site usually determines what traffic source I use. SEO and PPC being the main sources. There are other traffic sources like pops and zero click, but it's harder to convert these types of traffic due to lower quality. But if you just want traffic and not too concerned about making a sale, then it may work for you.

Social media networks (Facebook ,Twitter ,Google+ , Pinterest , Tumblr , Stumbleupon)
Youtube
Slideshare
Search engines
Google+ local pages
Paid advertising ( Google Adwords , Facebook Ads)
Rss Feeds
Offline Sources (business cards)
Guest Posting For Traffic

I would focus more on getting targeted traffic rather than just traffic. There are numerous ways to get traffic but not all will be ideal for your particular niche.

Social sites like facebook,twitter,g+, pinterest, tumblr etc. are good source for attracting traffic.
Other than these sites you have youtube, dailymotion ,slide share, scribd etc. to share your video creations and Presentations as well.
