Content spamming is a form of black hat search engine optimization that has the intention of altering the way a search engine perceives a page’s contents. There are several ways that this can be accomplished.
One of the most popular types of content spamming is to insert hidden or visible text right on the web page in the form of disguised keywords and phrases. These keywords are the same color as the background, hidden as a tiny font or hidden within HTML code, ALT attributes and “no script” sections. This helps attract a web crawler.
Yet another popular content spamming technique is called keyword stuffing. This involves the insertion of hidden, random text on a webpage to raise the keyword density or ratio of keywords to other words on the page. This technique has become so common it is considered white hat SEO. Older versions of indexing programs simply counted how often a keyword appeared, and used that to determine relevance levels. Most modern search engines have the ability to analyze a page for keyword stuffing and determine whether the frequency is above a “normal" level. Similar is the practice of meta tag stuffing which is the practice of repeating keywords in the Meta tags, and using keywords that are unrelated to the site's content.
Yet another SEO tactic is to use what is called “Gateway" or doorway pages. These are low-quality web pages that contain very little content but are instead stuffed with very similar key words and phrases. They are designed to rank highly within the search results. A doorway page will generally have “click here to enter" in the middle of it and this is the link that leads you to the more human friendly aspect of a site. This type of content spam is also so common it is considered to be white hat.
