I have a resource which ranks #1 on the web for conference listing. I've discovered and been advised to add Microdata markup since it does no harm and if anything it helps search engines understand how my data is presented...The code below shows the tags correctly inserted as per the Google Wizard tool here: https://www.google.com/webmasters/markup-helper/I have several hundred of these <li> an event is placed in here </li> tags that list each of the events. My question  is, do I include the reference to the <li itemscope itemtype=http://schema.org/Event> in each event? Seems a bit overkill to call the URL 200+ times? The below is an example of ONE event, should they all be 100% the same as this?                                            <!-- Microdata markup added by Google Structured Data Markup Helper. -->                    <li itemscope itemtype=http://schema.org/Event>                        <a class=expand>                        <div class=right-arrow>                            +                        </div>                        <h2 itemprop=name class=events>2016 Small Business Cyber Security Conference</h2><span class=flag-icon flag-icon-us></span><span itemprop=startDate content=2016-02-10 class=eventdate>February 10, 2016</span> |                         <span itemprop=location itemscope itemtype=http://schema.org/Place>                        <span itemprop=address itemscope itemtype=http://schema.org/PostalAddress>                        <span itemprop=streetAddress>New York, New York,</span>                         <span itemprop=addressCountry>USA</span></span></span></a>                        <div class=detail>                            <div id=left style=width:15%;float:left;height:100%;>                                <div id=sup><img itemprop=image class=img-responsive hidden-xs src=http://concise.education/conference.new/logo.png width=100%/></div>                            </div>                            <div id=right style=width:85%;float:right;height:100%;padding-left:20px;>                                <div id=sup>                                    <div>                            <span itemprop=description><strong>Cyber Conference Overview:</strong><br/>                            Description here....</span><br/>                            <br/>                            <a itemprop=url href=http://events.constantcontact.com/register/event?llr=rzxqjaeab&oeidk=a07ec4cebsk3fabf91a>Visit Website</a><!--   <span class=twitterbox hidden-xs>@twitter</span>  -->                                    </div>                                </div>                            </div>                        </div>                    </li>++++++In other words, must each event start with <li itemscope itemtype=http://schema.org/Event>
Microdata markup - do I add to EACH markup reference?
