I run a website for English-speaking expats, who search for terms in English, the local language, and translations of the local language into English (which have their own variations depending on their parent country).
What's the best way to link all these terms together and let search engines know they're all referring to the same thing?
E.g. Ministry of Transportation = Misrad Hatachbura = משרד התחבורה
<span alt_lang="משרד התחבורה | he-IL" alt_lang="Misrad Hatachbura | en-IL">Ministry of Transportation</span>
I feel like<p>Ministry of Transportation <span display="none">Misrad Hatachbura</span><span display="none">משרד התחבורה</span></p>
is a horrible way to go.
