I have 3 Wordpress instances of the same site in different languages hosted in different regions - Ireland, Russia and Spain. The 3 sites are code identical - just the content is different.
I'm planning to combine them a use a multilingual plugin instead and redirect the .ru and .es versions to the .ie site. I'm wondering:
- Is this a good idea? Are any multilingual plugins good enough?
- Is an search engine penalty likely?
- Do search engine rankings rank much better if each site is hosted in the respective country? e.g. .ru is hosted in Russia and not Ireland. My main concern is a bit hit on the search rankings.
