Detects language and automatically displays pages in vistor's preferred language.
Until now, a multilingual Job Board served the first page in default language, even if visitor's language was other. The visitor then had to locate the link (a flag icon) to switch to language they understood. This was a big problem, because many visitors were unable to find the link even if it was right in front of their eyes.
(A general rule of "good user experience" is that a user must find sought-after information within 1-2 clicks. Otherwise they will be lost forever.)
But no longer! LANGDET will detect user's preferred language and
upon the first request serve the correct page. (Assuming that their language is available.)
LANGDET is a '
must-have' plugin for all bilingual and multilingual sites.
Version 2.x features additional enhancement of alternative language detection method based on geographical location. This method will be enabled only if you also use the TRAFFIC COP plugin.
(LANGDET doesn't need TRAFFIC COP in order to work properly, but it will work better if you use TRAFFIC COP.)
HOW LANGDET WORKS?
There are 2 methods to determine user's language: 1.) by parsing the header (from the user's browser) "ACCEPT-LANGUAGE", and 2.) choosing language from user's geographical location (country).
LANGDET uses both of these methods. First, LANGDET parses the header "ACCEPT-LANGUAGE". If unsuccessful, the latter method is used. (However, to enable the latter method, it is necessary to use the TRAFFIC COP plugin.) When the latter method is unsuccessful, the default language is chosen as a last resort.
It must be mentioned that the browser header "ACCEPT-LANGUAGE" is not always present, and if it is, it may be empty. This is why an alternative language detection method is helpful, so that
a page is served in correct language upon first request.
SITUATIONS WHEN HEADER 'ACCEPT-LANGUAGE' IS NOT PRESENT
- User deletes language preferences from his browser settings.
- Search engine robots don't use a browser to access your pages. Header 'ACCEPT-LANGUAGE' may or may not be present.
- .... etc.
