Every Search Engine Marketing Campaign Should Have a Directory Strategy
By Karin McLean

It is a best practice to include a directory strategy as part of your search engine marketing (SEM) campaign for two important purposes: to increase the visibility of your website within the overall search market and to increase the link popularity of your site through increased, relevant listings.

Search directories play a key role in search engine marketing. Not only are they influential in their own right (according to StatMarket Research, the Yahoo! Directory is the number two most frequently used search property), but they also influence other search properties. For example, Google’s search results ranking algorithm considers how your website is listed in the Open Directory Project (a major search directory) as part of its criteria for ranking your website in its search results.

It is a best practice to include a directory strategy as part of your search engine marketing (SEM) campaign for two important purposes: to increase the visibility of your website within the overall search market and to increase the link popularity of your site through increased, relevant listings. In creating a directory strategy, it is important to decide which directories to target, and which type of directories will help to build the most relevant community for your website. You should begin by targeting the most influential directories -Yahoo! and the Open Directory Project will provide the most value to your campaign.

Yahoo!

Yahoo! is the first directory to emerge in the development of the Web, providing users with a search portal that was organized by content category, making it easy to navigate. Yahoo! is second only to Google in the number of search referrals it directs to websites.

Currently, Yahoo! allows one directory listing per domain and charges $299 per listing per year. All listings are subject to change or rejection by Yahoo!’s category editor. This channel may provide fewer rankings for your site than others, but because of it popularity, listings in Yahoo! receive more weight by the algorithms of the major search engines than other directories in determining link popularity.

The Open Directory Project

The Open Directory Project (also referred to as ODP or DMOZ) is a directory that currently has over 63,000 volunteer editors who review and accept or reject directory submissions.

Just like Yahoo!, submitted directory listings are subject to changes by the directory’s editors, however the Open Directory Project is a completely free directory. The most important fact about the Open Directory is its influence on Google. Google often updates its copy of the Open Directory Project database, and uses those listings to guide its crawler. Therefore, having a listing in the Open Directory Project is extremely important to a site’s visibility in Google, the number one search engine according to market share, as well as to its overall link popularity.

Although the directories mentioned above are the most influential, all legitimate directories that include a website listing and help to build a relevant community around that website are important. The following directories should also be considered for any search engine marketing campaign.

Business.com

Business.com does not directly influence any of the top search properties. However, it does contribute to a web-site’s relevant community. Business.com is a business-to-business directory that allows sites to build their contextual relevance within a business vertical. Directory listings in Business.com cost $99 per year.

Zeal

Search directory Zeal is comprised of both professional and volunteer editors, and is owned by LookSmart. The Zeal directory listings comprise a portion of the LookSmart directory results. Zeal volunteer editors are invited to submit websites at no cost to the directory that they believe are relevant to the specific category they edit. A site must be submitted by a Zeal editor to be included in the database. Zeal prides itself on being a community of enthusiasts trying to build a more comprehensive directory through editors’ experiences.

About.com

About.com is not considered a true directory; however, its categories (or “guides”) were constructed to build relevant areas for users searching on particular topics to find information, “how–tos” and links to relevant websites. About.com is considered important in building a relevant search community for a website. Your website’s inclusion in About.com reconfirms that the theme of your site corresponds with the topic being searched by users. About.com does not have a fee associated with inclusion.

It is important to create an inclusive strategy for the niche directories that are becoming more popular among Internet users. The importance of these smaller more targeted directories is to gain recognition for your site and its offering within your particular online community. Becoming an authority in your target market/industry can be influential in your website’s online visibility and potentially influential in your natural search engine rankings because more relevant links boost link popularity.

Directory Strategy

These general directory recommendations provide a good place to start, however, it is important to develop a comprehensive site-specific directory strategy as part of your search engine marketing campaign. Search engine marketing professionals are experienced and skilled in writing directory listings that accurately reflect the site’s content and that conform to the guidelines of each directory.

It is critical that directory listings be written and submitted correctly from the start, because once they are accepted, they are difficult to change. Researching which directories are the most influential and relevant to a particular site is also extremely important. Most of the major directories charge a fee for inclusion into their databases. These fees are well worth the price, since these paid programs lend great value to natural search results. Once submissions are accepted to the directories, increases in link popularity and visibility should occur. Visibility drives traffic and conversions, and they drive sales.
