He said it affected 0.6% of English-US queries to a noticeable degree and was unrelated to Panda and Penguin. Google's exact match domain system still exists today. ## Key takeaways - Google's Matt Cutts announced the change on X on 28 September 2012, not in a blog post. - Cutts said it affected 0.6% of English-US queries to a noticeable degree. - The target was low-quality sites on exact-match domains, not every keyword domain. - Cutts himself called it the exact-match domain (EMD) algo, so the name traces to Google. - Google's ranking systems guide still lists an exact match domain system. ## What Google changed Google did not blog about this change. Matt Cutts, then head of Google's webspam team, announced it in two posts on X on 28 September 2012. The [first](https://twitter.com/mattcutts/status/251784203597910016) said a "small upcoming Google algo change will reduce low-quality 'exact-match' domains in search results." The [second](https://twitter.com/mattcutts/status/251789327691042816) said it was "unrelated to Panda/Penguin." An exact-match domain is one whose name matches a search query word for word. The target was low-quality sites relying on that match, not every site with keywords in its domain. ## When it rolled out Cutts called the change "upcoming" and gave no exact launch day and no completion date. This page uses 28 September 2012, the date of his posts. [Search Engine Roundtable](https://www.seroundtable.com/google-emd-update-15776.html) and [Search Engine Land](https://searchengineland.com/low-quality-exact-match-domains-are-googles-next-target-134889) reproduced both posts that weekend. The name traces to Google. Cutts's own second post called it the "exact-match domain (EMD) algo," and the industry's "EMD update" label came from that. ## What is known about its impact Google gave one figure, in Cutts's second post: the change "affects 0.6% of English-US queries to a noticeable degree." Google gave no figures for other languages or for how many sites were affected. Treat any other percentage attributed to this update as a third-party estimate. ## What site owners should do The system still exists. Google's [ranking systems guide](https://developers.google.com/search/docs/appearance/ranking-systems-guide) lists an exact match domain system and says Google treats "the words in domain names as one of many factors" for relevance, while making sure it doesn't "give too much credit" to domains designed to match queries. In practice: - Choose a domain for your brand, not to rank for a query. - Do not expect a keyword domain to lift thin content; the content still has to earn the ranking. - If you already run a keyword domain, it is not a problem in itself. Build it into a real brand with useful pages. ## How to check whether it affected you This is historical: Search Console keeps 16 months of data, so it cannot show September 2012. If you kept analytics from then, compare organic Google traffic for a week before 28 September 2012 with a week in mid-October. The [Google Algorithm Updates timeline](/updates) lists the other updates of 2012, so you can rule them out first. ## Related updates - The [Pirate update](/updates/pirate-update-2012) was the spam-focused change before it in 2012. - The [Penguin update](/updates/penguin-update-2012) is the update Cutts said it was unrelated to. - The [Payday loan update](/updates/payday-loan-update-2013) was the next spam-focused change, in 2013. ## Frequently asked questions ### When did the exact match domain update launch? Matt Cutts announced it on X on 28 September 2012, calling it a small upcoming change.

Yes, through posts on X by Matt Cutts, then head of Google's webspam team, rather than a blog post. Search Engine Roundtable and Search Engine Land both reproduced his posts the same weekend. ### Are exact-match domains bad for SEO? Not in themselves. Google's ranking systems guide says words in domain names are one of many relevance factors, but its exact match domain system stops giving too much credit to domains built to match queries. ### Who named it the EMD update? Matt Cutts did, in effect. His second post called it the new exact-match domain (EMD) algo, and the industry used that abbreviation for the update. ## Sources 1.
