Introduction
Hidden links are ones that real people aren’t supposed to actually notice or click on
Hidden links is a way to guide a search engine to our doorway pages.
New dynamic “hidden link” technique for linking a large highly connected graph in a simple hyperbolic space without cluttering the display.

In a hyperbolic space, the far away nodes/edges (paths) are diminished when the user is not focusing on them.
The user can dynamically warp the display to focus on thousands of different nodes for navigation.
This graph is a non-cyclic hierarchical hyperbolic structure without multiple connected paths.

New Technique
The user can easily navigate through all possible paths without tracing many lines and intersections
Robot programs called spiders create search engine databases, computer robot programs that crawl the web seeking search engine content
Pages created as the result of a search are called "dynamically generated" pages .

In a directed non-cyclic hierarchical space, there is a primary graph, which links all the nodes in a tree form. These links are primary tree links. The others are non-tree/cross links in a highly connected graph. A node can have one incoming primary link and many non-tree/cross links.

The basic link tag looks something like <a href="hidden.html">click here</a>.
<a href="hidden.html" style="cursor:help">
<a href="hidden.html" style="color:#FF0080">
<a href="hidden.html" style="text-decoration:none">
Cursor Type …………. auto ……………crosshair ……………hand

Build hash table of links in the website.
Partition web log by visitor
For each visitor, partition web log file such that each subsequence terminates in a target page.
For each visitor and target page, find any expected locations for that page:

Conclusion
The hidden link technique enables the mining
of large hierarchies with multiple secondary
paths
Hidden link enables the user to easily navigate
through different links without being
overwhelmed with large member of nodes and
paths.
