To attract international visitors to your real estate web site, the latter needs to be first translated into any given language (in my case from English, Dutch and Spanish to French).
Once this is done, a SEO (Search engine optimizer) like me will improve the way your website has been built by revamping the site's structure, file naming, etc. and introducing the right keywords at the right place, rephrasing sentences to make them Search Engine friendly or simply by writing some content.
You need to think about your localised website as a different entity, requiring particular efforts adapted to reach the local audience of your choice.
I have been promoting over 10 multilingual websites (mostly in English, French, Spanish, Dutch, German and Italian) and I provide the best results in English and French, my two major languages.
I am currently looking to team up with a German speaking SEO to broaden my services.
