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. 谷歌的约翰·穆勒（John Mueller）在推特上说：“我们没有有毒域名的概念。” 有人在答复第三方SEO工具时说，指向他网站的某些链接质量低下，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，大多数网站没有有害链接。因此，我猜想有毒链接周围存在某种“概念”，但我怀疑Google在内部将这些链接归类为有毒链接。

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. 根据定义，PageRank根据这些链接的信誉为链接赋予不同的权重。但是这些权重是否为负？我对此表示怀疑，自企鹅4.0之后就没有。

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. 当然，无论如何，我认为通过手动操作，某些链接在损害网站排名方面可能是“有毒的”。但是使用Penguin 4.0，Google现在从算法上只会忽略指向您网站的错误链接。
