I'm producing a DIY multilingual site. I'm using a templating engine (rainTPL) and my own static language files (php arrays).
In these files I not only have the page strings but also the meta tag and title contents. I'd just like to know if you think this is a bad idea.
The 'current language' is set via a session variable not a querystring, so urls are identical, no matter what the current language.
So, will SEO be a problem? There could be a load of possible title and meta tag alternatives for the same page, depending on the user's current language.
If you think this is a problem, could anybody suggest an alternative?
