Exact Match Domain (EMD) Update

The Exact Match Domain (EMD) Update was a Google algorithm change in September 2012 that reduced the rankings of low-quality sites whose domain name exactly matched a search phrase. A domain such as cheap-car-insurance-quotes.com could no longer rank mainly because of its name.

What an exact match domain is

An exact match domain (EMD) is a web address made up of the keyword someone might search for, such as bestrunningshoes.co.uk or london-plumber.com. For years, owning one gave a noticeable boost. The domain name matched the query, it was often bolded in results, and links that used the brand name automatically used the keyword as anchor text.

This created a market for keyword domains. Many were turned into thin affiliate or ad-supported sites that ranked well despite offering little value.

What the update did

Google’s then head of webspam, Matt Cutts, announced the update on Twitter in late September 2012. He described it as a small algorithm change to reduce low-quality exact match domains in search results, and said it affected about 0.6 percent of English-US queries to a noticeable degree.

The important word is low-quality. The update did not penalise every keyword domain. Sites with an EMD that also offered useful content and a real business could keep ranking. What disappeared was the easy advantage of having the keyword in the name.

It arrived around the same time as other changes, including a Panda update, so many sites hit that week were affected by more than one thing.

Do exact match domains still work?

An EMD is not harmful in itself, and it can still help users understand what a site is about. However, it no longer provides a meaningful shortcut. Rankings depend on the same things as any other site: relevant content, a good experience and genuine links.

There are also trade-offs to consider:

  • Keyword domains can look generic and less trustworthy than a distinctive brand.
  • They can limit growth if the business later expands beyond that one product or place.
  • Building a memorable brand tends to support branded search, which an EMD struggles to do.
  • A location in the domain can make expansion to other areas awkward.

How to choose a domain today

  1. Pick a name that is short, memorable and easy to spell.
  2. Favour a brand over a string of keywords.
  3. Use a country code such as .co.uk if you serve one country; see ccTLD.
  4. Check the domain’s history before buying, to avoid inheriting spam or penalties.
  5. Put your effort into URL structure and content rather than the domain name alone.

Common myths

  • “Google penalises all EMDs.” It targeted low-quality ones, not the domain type.
  • “An EMD guarantees rankings.” Not since 2012, and arguably not for a long time before that either.
  • “Buying an expired keyword domain is a shortcut.” Using expired domains to manipulate rankings can break Google’s expired domain abuse policy.

Key Takeaways

  • The EMD Update rolled out in September 2012.
  • It reduced the rankings of low-quality sites with exact match domain names.
  • Matt Cutts said it noticeably affected about 0.6 percent of English-US queries.
  • Good-quality sites with keyword domains were not targeted.
  • A distinctive brand name is usually a better long-term choice than an EMD.
