I wouldn't be worried if my content is useful to users and have a good level of quality

Hi, I had a similar problem where our homepage was out ranking the target page. It was down to a number of things but mainly the fact that a lot of links using the keyword anchor text were pointed at the homepage. I would be surprised if your new page replaces the homepage in the SERPs soon after launching it. You'll need to do a few things first. Either build new links or get the existing links repointed to your new landing page Make sure your on-page SEO is spot on Use your internal links effectively to point to your new page using the targeted keyword Hope that helps, Brendan.

Do you have the option of not displaying the extension on your URL? That way no matter what underlying language you use, you have the same URL and don't have to worry about updating links in the future.

Yes, the listing may lose the ranking if those 100 backlinks are from worthy sites.
