I have build a Web Application and the website is set-up like this:Landing Pages that consists of Home, Price, Features and Contact Us Web Application pages that are for logged in users and only the Login page and Register page can be accessed by Search Engine bots.At the moment, I have the following schema microdata for all pages, including the landing pages as well as the web application pages:<body itemscope itemtype=http://schema.org/WebApplication>  <meta itemprop=name content=Awesome Education App>  <meta itemprop=about content=Education App for smart people.>  <meta itemprop=applicationCategory content=EducationApplication>  <meta itemprop=author content=Mr Smith>  <meta itemprop=creator content=Example Company>  <meta itemprop=country content=Australia>  <span itemprop=offers itemscope itemtype=http://schema.org/Offer>    <meta itemprop=price content=5.00 />    <meta itemprop=priceCurrency content=AUD />    <link itemprop=availability href=http://schema.org/InStock />  </span>  <meta itemprop=keywords name=keywords content=education app, etc, etc>  <ul itemscope itemtype=http://schema.org/SiteNavigationElement>     <li><a href=home>Home</a></li>     <li><a href=price>Price</a></li>     <li><a href=features>Features</a></li>     <li><a href=contact-us>Contact Us</a></li>     <li><a href=web-app/login>Login</a></li>     <li><a href=web-app/register>Register</a></li> </ul>    </body>My questions are:1) Do I have separate schema for Landing Pages and the App Pages? I mean have something like this:Have this Schema for Landing Page, Price Page and Features page like this:<body itemscope itemtype=http://schema.org/WebPage>...<body>Have this Schema for all App Pages:<body itemscope itemtype=http://schema.org/WebApplication>...<body>2) Do I add schema for offer, about etc in each individual pages (such as: itemprop=price in Price page and itemprop=about in Features page) or can I have all data in every pages like my example above?3) The App I have created is an education app. Can I use applicationCategory schema like this or is this invalid. If it is invalid, what will be the best category in this case:<meta itemprop=applicationCategory content=EducationApplication>4) Can I use SiteNavigationElement with WebApplication schema type?5) Lastly, with the SiteNavigationElement for menu items, is my example method correctly implemented or do I need add itemprop for each individual menu items?Thank you so much for your help.
