I still believe that Facebook and Google are great platforms to promote your business, but only if you are willing to pay. If your goal is Organic growth, I recommend looking at newer platforms such as Quora, Reddit, Snapchat, Medium, Instagram, Tumblr and similar. These are all established platforms that still offer some opportunities for organic reach, because although popular, they are nowhere near the saturation levels of Facebook and Google. You can also look at startups that you feel will become very successful in the future, take a small gamble perhaps and try to establish a strong presence there.
Sometimes considered to be a part of SEM, social media sites like Twitter, YouTube, Facebook, and Delicious have search fields and also pass authority to sites through links. Making sure your content and links are placed (where necessary) on these social media sites can increase your influence in user search engine queries. SMM is a rapidly growing area of Internet marketing but to discuss it further is beyond the scope of this Guide.
Although it may have changed slightly since BrightEdge published its report last year, the data still seem to hold true. Organic is simply better for delivering relevant traffic. The only channel that performs better in some capacities is paid search ads, but that is only for conversions, not overall traffic delivery (Paid Search only accounted for 10 percent of overall total traffic).
