Directory Listings as Part of Your Private Practice Marketing Effort, Part 2

Paid Inclusion General Directories

There are many more paid inclusion directories, but here we'll just cover two of the most important ones.

Yahoo!

Yahoo! famously began life as a free general directory maintained by a couple of university students, but over the years it has grown into the largest and most influential of the paid-inclusion directories. Note that Yahoo! provides both a search engine and an edited directory; it's important to note that your site can be included in the former without appearing in the latter.

The last time I checked, the reviewing fee for a commercial site (which does not guarantee that a site will actually be included in the directory) was a minimum of a hefty $300 every year. Non-commercial sites can be reviewed for free, but be prepared for a wait of months or even years before a site is approved. Yahoo! claims to prohibit multiple listings in its directory, but as in the case of DMOZ editorial abuses, some of the less scrupulous webmasters have played the system and wound up with many separate directory entries.

Business.com

The Business.com directory is carried by a network of sites that includes Business Week, Inc.com, FastCompany.com, C|Net, Internet.com and others. Like Yahoo!, Business.com charges a recurring annual fee, although the fee is slightly more modest (about two thirds of what Yahoo! charges). Business.com claims something like 25 million business users, and if your site is at all targeted at business customers, a listing in Business.com could be a good fit.

Niche Directories

There are too many niche directories out there even to begin listing them, but if you can think of a topic, someone is probably running some variety of directory devoted to it. If you can find a good niche directory which lists quality sites that are related to yours, and which preferably garners a bit of its own web traffic (see our pages on using Alexa to find out), it may be worth your time to get listed.

I mentioned above that you should aim for directories which carry quality sites for a specific reason: some of these sites just look like humanly edited directories, but in fact they operate with link farm software that automates the whole process of listing and describing sites -- meaning that there is actually little or no editorial oversight of the process.

Which brings us to the topic of link farms...

Beware of Link Farms!

A link farm is a database of links, usually maintained automatically, and usually requiring a reciprocal link back to it from every site it lists. On first glance, they sound pretty harmless; where's the problem?

Many people know that inbound links from other sites can boost a site's search engine positioning, particularly in Google. Google's PageRank technology, a favourite topic of web pundits everywhere, interprets links to a given page as 'votes' for the relevance of that page. Roughly speaking, the more (relevant) pages link to a given destination page, the more credit accrues to that destination page. Naturally, nothing in the world of search engines is that simple, and the reality is much more complex -- both in the original academic papers which gave rise to Google, and in its implementation today. The exact method of calculating PageRank today is not publicly known, and as a result, much of the punditry and authoritative prognosticating about it is educated guesswork, at best.

Sometimes lost in all that punditry, however, is an important fact: reciprocal linking with low-quality databases of links in the web's 'bad neighbourhoods' can actually harm a site's search engine positioning. Why? Search engine algorithms are getting increasingly good at identifying when a set of links is just a set of links, with little or no added value. (Often, link farms have no unifying theme -- your listing of a mental health service might appear right next to a listing for hair tonic -- and even those which do employ some kind of organizational structure typically provide no original content.) Such sets of links are effectively downgraded in importance and contribute very little to the PageRank of linked sites. Search engines can also tell, of course, whether links to listed sites are reciprocal -- in other words, they can tell whether a webmaster has knowingly linked back to a link farm. And in that case, Google has publicly stated that the site linking back to the link farm may be penalized; it seems likely that other major search engines have adopted a similar approach.

So, by all means do try to get listed in quality directories, and do seek out links from other relevant sites, but my advice is to avoid link farms like the plague!
