| Google Dance | Corresponds to the period of the month at which
Google updates the values of PageRank of the pages indexed
in its base. This one generally starts at the end of the month
and lasts one week. During this time, the ranking of a Web page
in the results of a search goes up or down (you understand why
it is called a dance). It is the same for its visible PageRank in Google Toolbar.
According to the geographical area of the Net surfer, one of
the thousands of servers of Google will give the results to
the search, which will differ according to whether this server
is updated or not. We developed a tool allowing to simultaneously search the 3 index (www, www2 and www3) to anticipate during the "dance" the future results of Google. |
| Googlebot | Name of the indexing robot of Google, which scans the Web from link to link looking for new pages. You may know if googlebot came to visit your site by looking at the log files of your server. |

| Orphan | A page is known as orphan if no other establishes a link towards it. If his URL were not connait, one can never fall above, so that in general it is not indexed by the search engines. |
| PageRank (PR) |
Index of popularity of a Web page, calculated according to a very sophisticated algorithm, worked out by Google. By abuse language, PageRank of a site is (in general) that of the URL principal (that can thus be different from PageRank of the banner page). |
| Hidden pages | When Google explores the Web, googlebot creates a copy of each examined page and stores it in a memory hiding place, which makes it possible to consult this copy constantly, and in particular if the original page (or Internet) would be inaccessible. When you click on the bond "Copies hidden" of a Web page, Google posts this one in the state where it was during its most recent indexing. In addition, the hidden contents are that on which Google is based to determine if a page is relevant for your requests. |
| SERP | Search Engine Results Pages |

| www1 (resp. www2 and www3) | Refers to an not-official index of Google,

At this address, the data used for research correspond to those
of a temporary base during the updates. At the end of the update,
the official base is made up starting from the temporary bases.
It should be noted that since 2002, www1 is not accessible any
more. We developed a tool allowing simultaneously to question the 3 www indices, www2 and www3 to anticipate during the "dance" the future results of Google. |
