Do I need to translate my website in order to list it on multilingual / foreign search engines?
It is not necessary to translate your website in order to submit it on foreign search engines...
...however, you need to have at least 1 page in French optimized with French keywords in order to submit on French search engines, at least 1 page in Japanese optimized with Japanese keywords in order to submit on Japanese search engines etc.
Let's assume that you're trying to reach the Hispanic market:
We would then create a Spanish page optimized with your Spanish keywords. It would have a similar look and feel as your home page. It could be considered as your "Spanish entry page". Such page would tell hispanic users in their native tongue that by entering your website they should expect a content in English and that also all correspondence must be established in English as well... This is the "culturally correct" way to make your first steps on foreign e-markets.
Many rules and regulations apply in order to make a multilingual page "search engine friendly" according to each market. The rules are different for each language and this is why we ONLY use native experts in order to deliver results.
