Examples of Search Spam
Spam expressions
Let's look at spam methods that affect ranking algorithms.
When evaluating the relevance of text, search engines take into account where queries are located on the page. Each such location is a field. Common text fields for a page are the document body, the name of the web page (title), meta tags in the HTML header, and the resource identifier (web page address).
In addition, the pointers in the text that are related to the URLs pointing to and belonging to this page are the anchors of the text field. They often describe the content of the page quite well. Expressions in the text field of a web page are used to evaluate whether the page matches a keyword (group of words). Often, different fields have different weights. Spam expressions refer to the technique of defining the content of these text fields to make spam web pages match certain queries.
Ways to Spam Expressions

Spam in the document body
