SharePoint has multiple ways to add pages. It can be done in the document library (pages) or through the settings drop-down menu. For most users these are not the most practical and easy. An easier and faster way is to simply add a hyperlink or button on a page for user to click on. My favorite method is to add a button on the page in SharePoint style. The hyperlink I am using is exactly the same as the hyperlink in the settings drop-down menu.

Solution with hyperlink only
1. Edit the page where the button needs to be placed.
2. Add a Script Editor web part to the page.
3. Add the following code in the script editor.

 <a onclick="if (LaunchCreateHandler(&#39;PublishingPage&#39;)) { SP.SOD.executeFunc(&#39;sp.ui.dialog.js&#39;, &#39;SP.UI.ModalDialog.showModalDialog&#39;, function() { var dlgOptions = { url:&#39;\u002fsites\u002fknowledge\u002fBestPractice\u002f_layouts\u002f15\u002fCreatePublishingPageDialog.aspx&#39;, autoSize: true, autoSizeStartWidth: 550 }; SP.UI.ModalDialog.showModalDialog(dlgOptions); }); };" href="#">  
      new page  
 </a>  

4. Publish the page.

Solution with button SharePoint style
1. Edit the page where the button needs to be placed.
2. Add a Script Editor web part to the page.
3. Add the following code in the script editor.

 <div class="ms-comm-heroLinkContainer">  
   <a onclick="if (LaunchCreateHandler(&#39;PublishingPage&#39;)) { SP.SOD.executeFunc(&#39;sp.ui.dialog.js&#39;, &#39;SP.UI.ModalDialog.showModalDialog&#39;, function() { var dlgOptions = { url:&#39;\u002fsites\u002fknowledge\u002fBestPractice\u002f_layouts\u002f15\u002fCreatePublishingPageDialog.aspx&#39;, autoSize: true, autoSizeStartWidth: 550 }; SP.UI.ModalDialog.showModalDialog(dlgOptions); }); };" href="#" class="ms-textXLarge ms-heroCommandLink">  
    <span class="ms-list-addnew-imgSpan20">  
      <img class="ms-list-addnew-img20" src="/_layouts/15/images/spcommon.png?rev=23">  
 </span>new page  
 </a>  
 </div>  

4. Publish the page.
