We are currently working on redesigning our site and making it responsive. It is a search intensive site with complex functionality, a lot of search filters and a lot of content. Our mobile versions of certain pages need to hide some functionality (i.e. search filters) that exists in the desktop version and/or content (mainly blocks of text that are not necessary or are increasing page load in mobile devices). My questions is this: does the situation of having the same URL (responsive site) serving slightly different content (text and/or search filters) for certain pages in different devices affect our SEO (SERPs or otherwise)?
