Hi Snail, welcome to WebmasterWorld!
First lets lay out some basics.
Across Europe the websearch market is owned by the same three or four players you know from the US, or UK. What formerly had been a complex landscape of local engines is for the most part a nearly monocultural environment now.
Those engines operate with indexing all the web.
Now nearly all people in the online world, with the exception of people from english speaking countries, are presented with options, when searching the web. Those options are:
- search all the web
- search in documents in local language.
Now usually the second option is the default, at least on most huge portals.
What does that mean for you? All users worldwide will be able to find you, since they easily can change to worldwide results.
However many people won't change default settings, and the majority prefers results in their native tongue anyway.
IOW: translations are the way to go.
Now searchengines use automatic language detection. Therefore a page in, say, french in a otherwise swedish language site should come up in a search restricted to french language documents.
So far so good.
From now on we have two aspects to look at:
Lets look at ranking matters first. If you have one page in french in a site with swedish navigation, swedish internal linking, swedish anchortext in external links, what are the chances that page ranks well in any todays search engines? Actually, the situation with hotel sites is special, because the word hotel is the same across several major languages. You might therefore get the french page rank well for two keyword combos: hotel + destination name
hotelname + destination
in searches restricted to french lanuage documents.
Now that's not bad. But it's only this combo, none of the countless important qualified keywords you are targeting, like cheap + hotel + destinatio, or central + hotel + destination etc.
The other point to consider is the user. A user finds your page in a search engine results page, which was restricted to french results. He clicks, gets on the page, clicks further, see swedish text - and leaves faster than you can say hej.
Okay, in your case it's an english site, which more people are likely to understand. Still, an initial page in their native language has set expectations which are not fulfilled. Most users will click back to the search engine results page - which after all presents them with 9 or more alternatives, which ARE in their language.
There are many more issues with both ranking and user satisfaction. This however should be enough to show that your solution will not do much to help you achieving your goals.
We have in this forum discussed alternatives to your approach, which, while more costly, are likely to give you much better results.
