When people refer to "organic SEO" (search engine optimization), they almost always use it as a blanket term to describe the unpaid, algorithm-driven results of any particular engine. However, a sophisticated search engine optimization company will often take the meaning of "organic" one step further. To such companies, the description of "organic SEO" is not limited to what shows up in the "natural" search engine results - it includes the methodologies used to achieve such rankings. A search engine optimization company usually falls into one of two camps. A "White Hat" search engine optimization company will use a largely content-based approach and will not violate the terms of service of the major search engines. A "Black Hat" search engine optimization company will use a largely technology driven approach and often ignore the terms of service.
Neither approach is invalid (as I have said many times before, there is nothing illegal about violating a search engine's terms of service), and both can achieve high rankings. But a search engine optimization company that takes the word "organic" literally believes that the "Black Hat" approach is anything but "organic SEO." There's an "old" saying in the SEO industry that "content is king." This is not necessarily true. In my experience, good content is king.
Study after study has shown that when people use search engines, they are primarily seeking one thing: information. They are not seeking to be impressed by fancy flash sites. They are not looking for a virtual piece of art. A search engine optimization company that is truly practicing "organic SEO" recognizes this fact and will refuse SEO work when prospects insist that content addition is not an option. "Artificial SEO" firms, which embrace a technical loophole philosophy, will allow a company to leave its website exactly as it is, because the work that such firms do is by and large technical and is designed to trick the engine into showing content that it would not otherwise. Certainly, there are acceptable (from the engine's standpoint) technical aspects that any good search engine optimization company will use, such as relevant page titles and meta tags. But there are many more unacceptable technical methodologies than acceptable ones, including cloaking, redirects, multiple sites, keyphrase stuffing, hidden links, and numerous others. A company practicing "organic SEO" will avoid these. As any search engine optimization company knows, inbound links are critical to the success of an "organic SEO" campaign. But there are different ways to go about it.
Firms that practice true "organic SEO" will look at the website itself and say "how can we make this site something that other sites would want to link to?" A search engine optimization company using "artificial SEO" will ask "how can I get links pointing to this site without adding anything of value to it?" The latter approach usually leads to reciprocal linking schemes, link farms, the purchase of text links, and more - anything save for making changes to the website that entice others to link to the site without the link being reciprocated, without paying the website owner, or without asking "pretty please." There is a stark contrast between "organic SEO" and "artificial SEO." Of course, any decent search engine optimization company will make certain that a site is listed in all the popular directories, such as the Yahoo Directory, the Open Directory Project, and Business.com. A good search engine optimization company will also continually seek any industry specific directories where your site should be listed. But truly using "organic SEO" means evolving your site into something that holds actual value to your prospects. In my opinion, this is much more beneficial in the long run than the artificial methodology of trying to garner incoming links that the site does not truly deserve. Search engines change algorithms frequently, and for two reasons. One is, of course, to improve their results based upon their most recent user studies. The other, which is obviously related, is to remove sites that are ranked artificially high.
Such updates raise panic in the SEO community - particularly among "artificial SEO" practitioners who have just discovered that their most recent and cherished trick no longer works (and may have gotten their clients' sites removed from the engines altogether). It is not uncommon on the search engine forums to see the owner of such a search engine optimization company threatening to "sue Google" over a recent update. Not uncommon, but always amusing. There is, with only a few exceptions, a common denominator in the websites that remain highly ranked throughout these algorithm shifts. They offer something of value to their visitors and are considered a resource for their industry. "Organic SEO" practitioners generally do not have to worry about going back and redoing work because of an algorithm shift. While an "artificial" search engine optimization company desperately tries to re-attain the rankings it lost for its clients (or to get the sites re-included in the search engine at all) because it was dependent on technical loopholes that have now been closed, "organic SEO" firms continue adding valuable content to a site, strengthening its value and bolstering its rankings. A common argument from companies when advised by "organic SEO" practitioners to take this approach is "we aren't trying to provide a resource for our industry - we are trying to sell products or services." This is, in my opinion, shortsighted. Remember, you are trying to reach prospects in all stages of the buying cycle, not just the low hanging fruit ready to buy now.
Let your website be their resource to learn about your industry, rather than your overpaid salesperson. Prospects are very likely to call you when they are ready to buy - after all, you've done so much for them already! In addition, taking advantage of "organic SEO" to make your website an industry resource provides a tremendous natural boost to your rankings for your individual product or service pages. This means that with "organic SEO", you'll get the best of both worlds. You'll reach people early in the buying cycle, educate them, and steer them toward your solution by using your website instead of your sales personnel. You will also reach the low hanging fruit because your individual product or service pages, which are intended for people who are ready to buy now, will get a significant rankings boost. Search engines conduct very expensive and frequent studies on what their users want to see when they enter search queries. Obviously, no company has a more vested interest in serving up the type of results that their users want than the engines themselves. "Organic SEO" firms will take the "piggyback" approach. A search engine optimization company that uses "organic SEO" will try to learn what the results of these studies were by examining the sites that figure prominently in search engine results over long periods of time.
