It traces to the EMD update announced by Matt Cutts on 28 September 2012, which he said affected 0.6% of English US queries. Words in a domain remain one minor relevance factor. For a site, a keyword domain is not a ranking shortcut, and a thin site on one gains nothing from the name. ## What is the exact match domain system? The exact match domain system is a Google ranking system that prevents content from getting too much credit simply because its domain name exactly matches a query. Google lists it in its [ranking systems guide](https://developers.google.com/search/docs/appearance/ranking-systems-guide), using the example of a domain containing the words "best-places-to-eat-lunch". It began as the EMD update. On 28 September 2012 Matt Cutts, then head of Google's webspam team, announced a change to reduce low quality exact match domains in results and said it affected 0.6% of English US queries to a noticeable degree ([Search Engine Roundtable](https://www.seroundtable.com/google-emd-update-15776.html)). ## How does the exact match domain system affect rankings? Google says the words in a domain name are one of many factors it uses to judge relevance ([ranking systems guide](https://developers.google.com/search/docs/appearance/ranking-systems-guide)). The EMD system caps that factor when the domain was clearly designed around a query, so the name cannot carry a page that the content does not justify. Cutts described the 2012 change as unrelated to Panda and Penguin, and aimed at low quality exact match domains ([Search Engine Roundtable](https://www.seroundtable.com/google-emd-update-15776.html)). A strong site on a keyword domain is not the target; a thin site relying on its domain name is. ## What evidence is there that Google uses an exact match domain system? This page is labelled **Confirmed**. The system is named in Google's ranking systems guide, and the original update was announced on record by Matt Cutts in 2012. Google staff have kept playing down domain keywords since. In August 2023 John Mueller said a domain name will never make or break SEO and that he did not think a keyword domain brings any measurable SEO bonus ([Search Engine Roundtable](https://www.seroundtable.com/google-your-domain-will-never-make-or-break-your-seo-35875.html)). ## What should sites do about exact match domains? Choose a domain for the brand, not for a query. If you already run a keyword domain, it is not a problem in itself; the question is whether the site would deserve to rank under a neutral name. Test that by judging the content against the ranking pages with the domain hidden. Be wary of the common pattern the 2012 update targeted: a small site on a keyword domain with thin or templated pages, and a history of ranking mostly on the name. Consolidating such microsites into one branded site with real depth is usually the better route. - Confirmed: domain words are a minor relevance factor. - Confirmed: Google limits credit for query matching domains. - Myth: buying an exact match domain is a ranking shortcut. ## Which Laurelin audit checks test for the exact match domain system? The new check [Keyword domain carrying thin content](https://www.laurelinlabs.com/audit/guardrails/382-keyword-domain-carrying-thin-content) flags the combination the EMD system targets: a query shaped domain with little substance behind it. Related checks: [Thin content](https://www.laurelinlabs.com/audit/topical-content/159-thin-content) is the core weakness. [Keyword stuffed title](https://www.laurelinlabs.com/audit/topical-content/138-keyword-stuffed-title) often travels with keyword domains. [Doorway pages](https://www.laurelinlabs.com/audit/topical-content/177-doorway-pages) describe networks of keyword microsites. [Brand has no resolvable entity](https://www.laurelinlabs.com/audit/authority-network/264-brand-has-no-resolvable-entity) shows a site with no identity beyond its keywords. [Page per query variant farm](https://www.laurelinlabs.com/audit/guardrails/298-page-per-query-variant-farm) is the scaled version of the same idea. ## What are the key dates for exact match domain? - 2012-09-28: Matt Cutts announces the EMD update, affecting 0.6% of English US queries ([source](https://www.seroundtable.com/google-emd-update-15776.html)) - 2023-08-14: John Mueller says a domain name will never make or break SEO ([source](https://www.seroundtable.com/google-your-domain-will-never-make-or-break-your-seo-35875.html)) ## FAQ ### Do exact match domains still rank? They can, if the content deserves it. Google limits the extra credit from the name itself, so a keyword domain does not compensate for thin content. ### When was the EMD update? Matt Cutts announced it on 28 September 2012 and said it affected 0.6% of English US queries to a noticeable degree. ### Should I change my keyword domain? Not for this reason alone. Migrating a domain has its own risks; improving the content and building a brand identity is usually the better fix. Hub: [Guardrails, Agentic & Future-proofing](/topics/guardrails-future.md)
