Google: We Don't Have A Concept Of Toxic Domains

Google's John Mueller said on Twitter "we don't have a concept of toxic domains." It was in a reply about a third-party SEO tool saying some of the links to his site are low quality and maybe toxic. 谷歌的約翰·穆勒（John Mueller）在推特上說：“我們沒有有毒域名的概念。” 有人在答復第三方SEO工具時說，指向他網站的某些鏈接質量低下，甚至有毒。

Google said previously most site do not have toxic links. So I guess there is some sort of "concept" around a toxic link but I doubt Google classifies those links internally as toxic. 谷歌此前表示，大多數網站沒有有害鏈接。因此，我猜想有毒鏈接周圍存在某種“概念”，但我懷疑Google在內部將這些鏈接歸類為有毒鏈接。

PageRank by definition gives different weights to links based on the reputation of those links. But could those weights be negative? I doubt it, not since Penguin 4.0. 根據定義，PageRank根據這些鏈接的信譽為鏈接賦予不同的權重。但是這些權重是否為負？我對此表示懷疑，自企鵝4.0之后就沒有。

In any event, sure, I think with manual actions, some links can be "toxic" in terms of hurting a site from ranking. But with Penguin 4.0, Google now algorithmically just ignores bad links to your site. 當然，無論如何，我認為通過手動操作，某些鏈接在損害網站排名方面可能是“有毒的”。但是使用Penguin 4.0，Google現在從算法上只會忽略指向您網站的錯誤鏈接。
