PRG Pattern Link Masking



Back to top

JaJuMa "PRG Pattern Link Masking“ Extension prevents Crawling of Layered Navigation Links by Google and other search engines using the POST-REDIRECT-GET PATTERN (PRG PATTERN)“.

As a result, useless Crawling may be reduced significantly which leads to the available Crawling-Budget being used more efficiently, by focusing more on really relevant links. Furthermore, (Near) Duplicate Content issues caused by Layered Navigations are avoided and minimized.

Nevertheless, existing Layered Navigation URLs remain unchanged. Hence, when applying JaJuMa "PRG Pattern Link Masking“, existing (Back)-Links for Layered Navigation URLs still work as before and do not get lost and creating new (Back)-Links for and sharing Layered Navigation URLs in Social Networks is also still possible as before.
