I have a client that does 90% organic. And another that does organic and article marketing and very little advertising of any kind. I actually think, in his case, a print campaign would be splendid and we're working on that. If you do purely organic, you are often at the mercy of Google's whims. So if you do organic, there are a variety of things that must happen to protect against a change in algorithms including but not limited to other search engines. For instance, while we all know Google is king, there are some markets where Yahoo is actually a more important search engine or at least equal.
I think in the next few years, we'll start to see certain search engines for particular markets which will return results that are more important to these markets. This will be great for pitching to a particular group and reaching them without relying exclusively on search words in a more generic search engine.
Some clients do a combo of ppc and organic. For my clients, a balance of the two is crucial. It depends on the client and what they sell, though. And since I have such a variety of different clients, I have to advise based on their goals and sometimes that is not a product but they want to achieve something. Some goals, products or services do far better with a heavy
PR campaign and a print/web/direct mail advertising focus as support at the beginning. But for the most part, a message that can be communicated through several different media channels to a target market is ideal.
I think if you do sales letters, you most certainly have to do ppc because you don't get the benefit of page rank for a number of pages. This works better for many products, particularly if you have partnerships with other marketers who will pitch yours.
You just have to consider that menu driven sites will rank better organically most of the time as subject matter is condensed to a particular page. In the case of someone who is building a brand, they need the search engine equity over the long term. One of my clients has an internet store that has been online 11 years and that rank is key to her success while the paid support campaigns help her achieve new awareness. I never say never because I have to hear the client's goals and consider what it is they are selling.
As an advertising person, I do think a consistent paid message helps support the organic results. However, organic results are unmatched for credibility, particularly in some of the markets I work in. So like everything, it depends.
