We have deposite our articles published in our journals in Crossref and assigned a doi to each one, but when we check our eligibility to subscribe to the similarity checking service, it appears that our content has not yet been registered. (Results 0/0 - 0%. We’re sorry, but you are not eligible to register for our Similarity Check service just yet. It looks as though you haven’t registered any content with us yet.)
Could it be because there is something wrong with submitting our content?? Or because our content has not been registered yet??
Knowing that we have placed the HTML of the content links in the similarity check URLs box, and again the links that leads to the PDF files when submitting our content in other deposits.
At the end of the deposits, we receive emails confirming the success of the deposits.
