Which one wins in a fight? If I were a betting man, I’d put my money of organic search traffic. As exciting as it is to see a quick surge in traffic from an effective PPC campaign, I’d take sustainability over a short-lived win any day. And that’s just the surface. I’ve gone over several of the benefits that organic search traffic can have on your business. I’m talking about the kind of results that correlate with cold hard ROI.Use the insights, implement the action steps, and stay competitive.
The first one is pretty powerful and pretty awesome, which is investing in demand generation, rather than just demand serving, but demand generation for brand and branded product names. Why does this work? Well, because let's say, for example, I'm searching for SEO tools. What do I get? I get back a list of results from Google with a bunch of mostly articles saying these are the top SEO tools. In fact, Google has now made a little one box, card-style list result up at the top, the carousel that shows different brands of SEO tools. I don't think Moz is actually listed in there because I think they're pulling from the second or the third lists instead of the first one. Whatever the case, frustrating, hard to optimize for. Google could take away demand from it or click-through rate opportunity from it.
On April 24, 2012 many started to see that Google has started to penalize companies that are buying links for the purpose of passing off the rank. The Google Update was called Penguin. Since then, there have been several different Penguin/Panda updates rolled out by Google. SEM has, however, nothing to do with link buying and focuses on organic SEO and PPC management. As of October 20, 2014 Google has released three official revisions of their Penguin Update.

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).
