  SEO Analyst: Hi Friends,
  
  Can you suggest me how to implement "Site Link Search Box" for our online shopping website.
  
  I have updated the schema mark up in my website home page, but it is not updated in our SERP pages yet. ;
  
  <script type="application/ld+json">
  {
   ; "@context":"http://schema.org",
   ; "@type":"WebSite",
   ; "url": "https://www.nitraafurniture.com/",
   ; "potentialAction": {
   ;  ; "@type":"SearchAction",
   ;  ; "target": "http://www.nitraafurniture.com/SearchResults.aspx?Search={search_term}&multi=true",
   ;  ; "query-input": "required name=search_term"
   ; }
  }
  
  Please if any modifications required in code.
  
  Thanks

  Richard Hearne: Not every result will have the inline search box under their result:
  
  "Search box not displaying? The Sitelinks search box appears only for navigational queries and when relevant for users. Google algorithms use a variety of factors to determine when the box appears, including the information on the site and different types of navigational queries from Search users."
