Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
An SEO technique is considered white hat if it conforms to the search engines' guidelines and involves no deception. As the search engine guidelines are not written as a series of rules or commandments, this is an important distinction to note. White hat SEO is not just about following guidelines, but is about ensuring that the content a search engine indexes and subsequently ranks is the same content a user will see. White hat advice is generally summed up as creating content for users, not for search engines, and then making that content easily accessible to the online "spider" algorithms, rather than attempting to trick the algorithm from its intended purpose. White hat SEO is in many ways similar to web development that promotes accessibility, although the two are not identical.
If we can do that effectively, it is in the best interest of the search engine to serve our content to our target audience for us, providing highly targeted visitors to our pages at no incremental cost. This is the secret to the organic channel, and why organic search listings are so valuable. Other channels often come with additional cost for each new visitor provided.
Use social media. Build a presence on social media networks like LinkedIn, Twitter, Facebook, Google+ etc. All of these activities help to get your name out and website address out on the internet. Read about how we doubled our social media audience in a week. Add share buttons to your site to make it easy for people to share your content. And write content worthy of sharing.
Knowing which pages visitors go to directly gives you an opportunity to design those pages so they accurately and quickly address visitors' needs. For example, if you sell clothing and your new-arrivals page is a popular destination, you want to be sure the content is always fresh, and you want to provide easy access to the full department represented by each new item. Who wants to see the same items week after week on a page that is supposed to represent the cutting edge of your inventory? And if you're featuring a new raincoat or bathing suit, you want to let visitors also easily see your whole line of raincoats or bathing suits."
Earlier I touched on using ultimate guides to shift the awareness of the reader to facilitate a conversion. That’s a solid example. Your content can serve any number of goals including sales, lead generation, etc. You could even use it to warm up a cold audience before you expose them to a paid campaign. It can lower your ad costs and increase your click-through rates. The utility of content is endless. You decide.
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).
