Interpreting to optimise ranking
Writing for the web must take into account the logical search key words likely to be used, whatever the language or culture of the user. This will be crucial for the organic search results of your web pages.
Translating the French web content into English needs to take the same approach as writing in French. To understand the way the reader's mind works is essential.
English speakers don't necessarily search using the same key words as the French. The original text should be modified accordingly. The translation is more like interpretation than litteral translation.
