I applied my website to the Google News Publisher Center, the site is in wordpress. I added my RSS feed to the application, now Google warns me that: Feed Sections Incomplete articles. Update your feed to include full-length articles. An example of an article that’s incomplete is with title "Bamboo Airways (Vietnam) sends a new Boeing 787 to Prague to promote trade and tourism" from section "Aviation24.be latest news". Any suggestion?
Yes, your wordpress feed must have your complete article in the description tag, not just a small description.
