信任与不信任（Trust v No-trust）

谷歌容忍线将根据网站不同的地方的计算进行排名。对于一个已经证明了它的价值和让谷歌非常信任的网站，我们可能会看到这样的图：

受信任的站点

然而，对于一个新的网站，一个没有历史记录的网站，图可能会看起来更像这。

非信任的网站

唯一的区别是虚线“容忍线”的位置。

换句话说，谷歌对取得他信任建立权威的网站的容忍度要比新网站或一直无法达到适当水平的网站要高。

高权威网站有很多的信任，能承受一定量的垃圾SEO而不受到惩罚（稍后我们讨论“负面SEO”）。网站越权威，能承受的就越大。

另一方面，一个新的网站即使有少量的垃圾SEO（垃圾外链或者质量差的SEO）很快就会被惩罚。

The Google Tolerance line will be in a different place depending on the site that is being ranked.  For a site that has proven its worth and Google trusts a lot, we might see the diagram like this:

A Trusted Site

Yet for a new site, and one that has no track record to speak of, the diagram will probably look a lot more like this.

A Non-Trusted Site

The only difference is in the location of the dashed “tolerance line”.

In other words, Google are a lot more tolerant to sites that have built up authority and trust than they are to new sites or sites that have not been able to attain a decent level of authority.

A high authority site with lots of trust can withstand a certain amount of spammy SEO without incurring a penalty (see later when we discuss “negative SEO”).  The more authority, the more it can withstand.

A new site on the other hand, would be quickly penalized for even a small amount of spammy SEO.
