Progresive content filtering, with clean url's, using taxonomies as facets.

Ideal for eCommerce carts, real estate / properties sites, classified ads, or other sites with multiple categories, where users need to filter content progressively by applying filters from one or more categories.

Category Landing Pages

Taxonomy terms are used as Facets to help users filter content progressively. Similar to the way it is done on most of today’s eCommerce sites, like Amazon. This module can be used to improve your site SEO, (but be careful, you need to know what you are doing, see note at the bottom) so as the user applies different filters the clean URL's are preserved with each filter change. For example, if the user applies these three filters: Computer Monitors, Samsung and LCD, then the URL will look something like:

When the user then changes the filters to Computer Monitors, HP and LCD, the URL will change to:

Filters can be applied in various permutations, so producing a clean URL for each unique filter combination will allow search engines to index a huge amount of landing pages.

Node pages

When a user arrives on the “node body page”, like the product page, the full URL path will be preserved.

If a user finds the same product (node) with different filter permutations this will be reflected in the URL:

Futhermore, if a user arrives on the product page via a direct URL, say directly from a Google search, the filters from the URL will be applied automatically and menu items expanded and highlighted accordingly.

For example, if a user arrives on the site via this URL:

The menu tree / facets will look something like

Computer hardware
--Monitors (highlighted)
--Hard discs

--HP (highlighted)

--LCD (highlighted)

But if they arrive on the same product page via a different URL, say:

The menu tree / facets will now look something like

--Multimedia (highlighted)
--House appliance

Product type
--displays (highlighted)

--HP (highlighted)

This module produces "menus" on the fly, i.e. no need for rebuilding menus or indexing as the menu items are not Drupal menu items but just items in the block. This is useful for sites where taxonomies may change frequently.

Filters / facets blocks are cached for better performance.

NOTE: This module can improve your SEO, particulary for landing pages, but it will also generate duplicate url's for node body. I advise to add "nofollow" to all links to the node body that appear on the landing pages, i.e in the teaser of the node. Than to index actual node body you will need to implement site map or find another way to list nodes with follow link, like implement a view based on a primary category and have diferent template for that view.
