Some Black Hat SEO techniques
- Keyword Stuffing
- Cloaking.
- Doorway Pages or Gateway Pages
- Link Farming
- Hidden Text, etc.
Keyword Stuffing : -
"Keyword stuffing"
refers to the practice of loading a webpage with keywords or numbers in an
attempt to manipulate a site's ranking in Google search results. Often these
keywords appear in a list or group, or out of context (not as natural prose).
Filling pages with keywords or numbers results in a negative user experience,
and can harm your site's ranking. Focus on creating useful, information-rich
content that uses keywords appropriately and in context.
Cloaking.: -
Cloaking refers to the practice
of presenting different content or URLs to human users and search engines.
Cloaking is considered a violation of Google’s Webmaster Guidelines because it
provides our users with different results than they expected.
Some examples of cloaking
include:
- 1. Serving a page of HTML text to search engines, while showing a page of images or Flash to users
- 2. Inserting text or keywords into a page only when the User-agent requesting the page is a search engine, not a human visitor
Doorway Pages or Gateway Pages : -
Doorways are sites or pages
created to rank highly for specific search queries. They are bad for users
because they can lead to multiple similar pages in user search results, where
each result ends up taking the user to essentially the same destination. They
can also lead users to intermediate pages that are not as useful as the final
destination.
Here are some examples of
doorways:
- Having multiple domain names or pages targeted at specific regions or cities that funnel users to one page
- Pages generated to funnel visitors into the actual usable or relevant portion of your site(s)
- Substantially similar pages that are closer to search results than a clearly defined, browseable hierarchy
Link Farming : -
The process of exchanging
reciprocal links with Web sites in order to increase search engine
optimization. The idea behind link farming is to increase the number of sites
that link to yours because search engines such as Google rank sites according
to, among other things, the quality and quantity of sites that link to yours.
In theory, the more sites that link to yours, the higher your ranking in the
search engine results will be because the more links indicate a higher level of
popularity among users of the Internet. However, search engines such as Google
consider link farming as a form of spam and have been implementing procedures
to banish sites that participate in link farming, so the term link farming has
garnered negative connotations across the Internet
Hidden Text : -
Hidden text is textual content
which your visitors cannot see, but which is still readable by the search
engines. The idea is to load a Web page with keywords and keyword phrases that
would be unsightly to visitors but that would improve the page's rankings in
the search engine results, and to do so without letting your visitors see the
text. Hidden text is identified as search spam by each of the major search
engines.
