In order to increase the frequency of the keyword, intentionally in the Web page code, such as meta, Title, comment, picture alt and URL address and other places to repeat a keyword.
2, False keywords:
By setting up keywords that are not relevant to the content of the site in meta, such as setting up some popular keywords in title, to mislead users into the site, it also includes the link keyword and the actual content does not match.
3, Invisible text/link:
To increase the frequency of the keyword, deliberately place a paragraph in the web page with the same background color, containing dense keywords text. Visitors can't see it, search engines (spider programs) can find them. Similar methods include ultra small text, text hidden layer and other means. An invisible link is the behavior of adding a target optimization page to another page based on invisible text.
4, redirect (re-direct):
Use Refresh tags (Meta refresh), CGI programs, Java, JavaScript, or other techniques to quickly and automatically jump to another page when a user enters the page. Redirects enable search engines and users to access different pages.

Sometimes it's a similar way to create static portals for dynamic pages or to create different pages for different keywords. But unlike the bridge page is, the former is the actual content of the site to build, is what the visitors need, and the bridge page itself has no actual content, only for search engines to make a bunch of keywords filled with the link.
8, Invisible Pages (Cloaked page):
Refers to the same Web site to different visitors selectively return different page content. Search engines get highly optimized web content, while users see different content.
9. Repeat registration:
Violation of site submission rules, break the time interval limit, a Web page in a short period of time repeatedly submitted to the same search engine to obtain multiple results. This is mainly for other search engines, which Google claims did not submit to the site too strict rules.
10, the garbage Link:
Also known as "link Factory", refers to a large number of Web pages linked to the formation of a network system. Once a site joins a link factory, on the one hand it can get links from all the pages in the system, and in exchange, it also offers its own links. and the pages in the system will raise the link score.

In this case, some of the innocent cheated Web pages implicated, and some is the bridge page.
