Turnitin similarity
PDFs in a frame can’t be indexed, and neither can content that’s wrapped in javascript. These URLs will be used to index your content, so they need to resolve directly to the content itself - the full-text PDF, HTML or plain text content. Where should Similarity Check URLs point? You’ll also need to ensure that your hosting provider has whitelisted the Turnitin IP range to ensure that the content is available for them to index. If your content is paywalled, please make sure that your Similarity Check URLs prompt an authentication step before allowing a user to access full-text content. The metadata you deposit with Crossref is available to be searched and retrieved by everyone, and this includes Similarity Check full-text URLs. If you aren’t registering any journal articles and instead are registering other content types (such as conference papers), please contact us. The URLs must point directly to your full-text PDF, HTML, or plain text content, and you must continue to include these links in all future deposits. These URLs will be used by Turnitin to index your content into the iThenticate database, making you eligible for reduced-rate access to iThenticate through the Similarity Check service. When you apply for the Similarity Check service, you must ensure you have full-text URLs for Similarity Check present in the metadata of at least 90% of your registered articles (across all your journal prefixes).
