Content and Links
Black hat techniques develop content of a page and the links to a page for the purpose of search engines only. It is not meant to be seen by humans and there is a multitude of ways to accomplish this. If they are seen by humans they are so hard to navigate or read that they become useless. The aim of white hat content and links on the other hand are aimed at nothing else by the human reader.
Quality of work
When work is not meant to be seen it often doesn’t matter what the quality of it is. Black hat techniques that hide work don’t care what they are doing on the name of their client. Their work isn’t open to review either which makes it impossible for anyone to critique, give criticism or praise.
White hat work is visible and for this reason is presented in a way that satisfies the scrutiny of client, peers and professionals.
Many black hat techniques treat search engines as their enemy and they concentrate on working against them. White hat techniques will treat a search engine as their friend even if the aim of their website is for the benefit of human visitors and not search engines. For this reason white hat SEO can be used quite successfully for alternative audiences. The bonus is producing WebPages that rank well in search engines.
Black hat can only be successful in the presence of search engines.
Branding and Domains
There is always a risk of having a domain removed from a search engine index. At times it can be done accily or deliberately. Even white hat techniques are vulnerable. Yet there are techniques that can be employed to mitigate the risk of this happening.
However black hat techniques open themselves to a higher level of risk and there is very little they can do to mitigate their risk. They know this and as a result tend to treat domains as inconsequential or disposable. This is just one more example of how black hat techniques could not care who bears the results of their actions.
