Question

Google's penalties

Answer 1

One of the reasons why Google penalizes is when they abuse their algorithm with the intention of positioning a certain website at the top of the search results where its content has almost nothing to do with what the navigator is looking at that moment.
When a person collects as a result a site that does not correspond to his query Google enables a form to provide information about that fact.

Later, Google performs an analysis of the information provided, penalizing those Web sites for not complying with its rules.
The penalties can be:

• Delete them from the results of your searches
• Decrease your page rank
• Do not consider the links that originate from a certain page.

The Cloaking
It's when webmasters program their pages to return different content when the Google robot passes.
In this way, a greater number of keywords is generated. If the same happens when they are visited by users, there would be an almost illegible website that would be full of meaningless keywords.

For example: the phrase bad neighborhood (bad neighborhood) is searched and a site that provides tools for Webmasters appears:

The doorway pages

These are pages that are designed exclusively for search engines.
The key words are repeated in the TITLE, in the H1, et. In this way a page is created almost incomprehensible for visitors as it contains a large number of keywords scattered throughout the page.
It is a particular case within the 'Cloaking', where it is redirected to the web browsers of the users who visit it.

The hidden text

These are keywords within web pages that have the same color as the background, thus increasing the density of these keywords, without the user noticing, and maintaining the appearance of the page.
The Google robot archives the hidden text and detects these practices, penalizing accordingly.

Duplicate pages

It is when the same content is generated in two or more web pages. Google penalizes duplicate pages because users can reach the same information more than once.

The hidden links

It is a variant of hidden text to promote other websites using their own pages.
Usually they are inserted in the same color as the background of the pages so that they are not seen by visitors, however Google's robot does detect them.

Spam in weblogs and guest books

In weblogs you can leave opinions about news published. In the signature books ('guestbooks') people can leave their greetings and comments.
It is common to include the name and a link to the website of the person who expresses or welcomes. In this way, the link is:
<A href=http://www.sitio-web-del-visitante.com> Visitor's name </A>
It is presumed that Google is beginning to disregard the links coming from the signature books for SEO positioning.

The FFA and Link Farms sites

These are web pages where a link to the web page that is indicated for free is included. But it has two drawbacks:

1) Usually you have to register or provide personal information, where many of these sites sell email addresses to companies that then send 'spam' to the mailboxes of the email accounts.

2) In addition Google is penalizing these FFA sites, so the links from them will not be taken into account.

Keyword abuse

Keyword abuse is when you put keywords in a bunch of elements of a web page.
Google often penalizes these practices.

Sell ​​links

Google does not like that Webmasters sell links, because the way of generating the PageRank value is distorted.
Google may be penalized by preventing 'PageRank' from being transmitted between web pages.
