LAD Categorization - How are the Libraries and Directories categorized?

LAD Category Outline The LAD libraries and directories all have the same basic categorization scheme:


  • Grand Categories (GCat for short): are highlighted in yellow throughout all the libraries and directories left hand menu

  • Major Categories (MCat): are grouped within their GCat in the left hand menu of all the libraries and directories

  • Sub Categories (SCat): show up in the left hand menu when you select an MCat, revealing all of the SCats that are contained within that MCat. The SCat list is shaded.



These categories change from library to library
(matching the different terminology used by the various professional groups)


However the directory categorization scheme is totally consistent across all directories
( keeping more in line with common vendor categorizations in phone books and other reference materials )


The major difference between our approach for all the LAD categories and other categorization schemes is that we tried to design the categories using the common terms used when people search, to make information easier to find. The LAD categories are designed to maximize the probability that the all our visitors end up finding the information and vendors that they are seeking.


We search the net, so that you don't have to!




When purchasing advertising, some ads ( size and position determined ) are available for only the GCat level. Others are available at the MCat or the GCat level.

Purchasing an ad for an entire GCat means your ad will be displayed on each and every page of all the MCat's and all the SCats that are contained within that GCat.

Similarly, purchasing an ad for an MCat means your ad will be displayed on the MCat page itself and then on all the pages for the SCats contained within that MCat.

Pricing per GCat or MCat can vary between directories or between other GCats and MCats withing the same directory. This pricing variance is related to the number of pages (there is at least 1 page for every SCat) and the relative size of the market for that set of categories.
