Welcome to the Q&A Forum

While it may affect your presence higher up in the search engines - to start with - it's a perfect opportunity to develop some exciting content for that section of your website, an excuse (not that you need one) to present something new, if you will. And I don't just mean static pages, I'm talking content people can share - interesting, educational, inspiring (insert other relevant word here) content that links well throughout your website (and sends your readers/audience on a buying journey, starting at information/education, ending at checkout). Sure, 301 the old pages to the new one to gain whatever benefit you can out of them - but make sure you don't spend all your time worrying about this... jump on the social side of things and look at how visitors are interacting with your content, then think about how they might be tempted to share it (special offers, for example...) - the opportunities are endless. That's just my take on it. Don't spend all your time worrying about the re-structure; that's something I've just learned!

Thanks for you answer i'm going to talk to the hosting company!
