The nature of the SEO industry is different than any other advertising method. Where other forms of marketing are concerned, it’s fairly simple to find a college or university course to enroll in, and there you can learn some of the beginnings to print, radio, and even television marketing methods. But search engine optimization is a different sort altogether than the others, it’s not something that can be readily taught, and it isn’t a field that just anyone can work in.
A big reason that the very idea of teaching someone how to work in the SEO field is folly, is the same reason the market exists in the first place, the search industry on the internet. The methods that you can learn at any time from anyone working online are already past their primary use, and while they may still work on some level they’re out dated. The way that Google and Bing have their algorithms running and autonomous for the most part, means that you just can’t be ahead of the curve in the ethical SEO world. This is the primary reason that the black hat world and SEOs exist, and while the methods will work for a day or two, in the end the spiders will spot you, and the site will disappear from search. It should be common knowledge that if it seems too good to be true then it probably is, but it is always good to remember that point, if an agency approaches you promising the world on a platter, look twice and ask for examples before jumping onto what could be a sinking ship.
Going back to the way that Google, Bing and Yahoo work online, it should also be kept in mind that over the course of a year the search engines are updated 200+ times. So any course that is being taught about search engine optimization, that information is outdated after the first week of class. Think about that point from an old media perspective, television, radio and print advertising hasn’t changed much, if at all, in the last 50 years. Yet advertising and marketing on the web is in a constant state of change, how would it be possible to teach a course about something that is entirely different month to month?
Be wary of an individual or an agency who approaches you with claims of having gone to school to learn all there is about search engine optimization, because what you learn in a book, is already out of date on the web. Ask for examples of their work, see if they can provide a list of websites or perhaps a past client whom they were able to successfully build their online presence and improve their position within the results pages.
