Avoiding Search Engine Woes with Multiple Domains and Websites

Operating multiple sites using numerous domains is a great strategy for businesses appealing to a wide range of customers. But this approach may trigger search engine spam penalties, if you’re not careful with implementation.

A special report from the Search Engine Strategies conference, December 13-16, 2004, Chicago, IL.

Business owners have many reasons for purchasing multiple domains. For example, if a business has international offices and locations, having multiple sites written in an appropriate language can increase search engine visibility, conversions, and brand recognition. However, owning and maintaining multiple domain names and multiple sites can also cause problems with the search engines. This panel explored various issues that might arise with multiple sites.

Owning multiple domains

“There is no doubt there are situations where businesses need multiple domains,” said Michael Palka, Director of Search at Ask Jeeves. “Having unique, good individual content and business rationale should be the main reasons why you choose to have multiple domains.”

Ben Wills, Director of Search at WebSourced’s KeywordRanking.com, suggested three legitimate reasons for having multiple domains: company brand recognition with subdomains, product branding, and regional marketing.

“Microsoft has a section of their Web site for developers called the Microsoft Developer Network,” Wills explained. “However, they do not necessarily want the brand, Microsoft Developer Network, to be its own standalone brand. But they do want the brand name (Microsoft) prominently featured. Subdomains are a great way to utilize the brand strength of the main domain and have subdomains piggy-back off of the main brand.”

Sometimes an individual product or service has brand recognition on its own. For example, a popular product brand is Kenmore (from Sears) or maybe Tide (from Procter & Gamble). In this type of situation, having a separate domain and Web site is a good search engine marketing strategy.

“There are no one-size-fits-all types of solutions, said Bruce Clay, President of Bruce Clay, Inc. “Sometimes you have products that stand out enough on their own, and sometimes you have products that are synergistic—that brand together, that fit together.

Finally, if a business has international locations, having multiple domains with the appropriate TLD (top-level domain) string is a good strategy. “This is both for higher search rankings in local search engines, and also for user comfort,” said Wills, “making users feel like your business has a presence in their own backyard and can relate better to their needs, especially if the site uses the same language that site visitors use.”

Potential problems with multiple sites

“Multiple domains create as many issues as they address,” said Clay. “You can own 100 domains covering significantly different products, linking them to a central domain—each solving the subject-focus issues but creating linking issues. Furthermore, purchasing 100 domains loaded with keywords and pointing them to the same physical site can cause duplicate content issues. Each situation is unique and they all have to be handled differently.”

When dealing with duplicate content, especially when one domain might have good content and the other domains do not, search engines tend to keep the best site in their indices. One site might have excellent content, but the business owner might be trying to put out a bunch of domains to cover all of the bases, and that is not what we’re looking for,” Palka explained. “It is just a ploy that does not help our users nor our advertisers. In this situation, we say which domain is the best one and give that one the credit. We probably will keep one domain and get rid of all the other ones, and then we will adjust the rankings.”

“If you have 50 different sites with 50 different domain names and 50 different hosting companies, with a linking scheme to everything, you might get some short term results,” Wills further explained, “but the longevity of those results all will eventually raise a red flag with the search engines.”

Multi-site and multi-domain solutions

Some businesses have both a dynamic and a static site. The sites have different IPs on the same server. Typically, the static site shows up very well in the search engines, and business owners are worried about being penalized because both the static and dynamic site contain the same content. From a business perspective, the reason for having two sites is functional, such as a better shopping cart setup on the dynamic site.

“There are times where we’re not going to throw everything out. We might say we don’t need most of the sites and only put up one,” said Palka. “Or you can use the Robots Exclusion Protocol so we don’t spider the dynamic site.”

“We want all the content you have, but we don’t want it to rank falsely or be misrepresented,” Palka concluded, “because that unfairly penalizes the relevant content and sites.”
