JMIR Publications is not responsible for what appears on Google Scholar, as they are an independent third party index which conducts their sweeps of our websites according to their own schedule and practices.
Our sites, both for published articles and preprints, have all the meta tags that Google Scholar uses for indexing. You can see the meta tags when navigating to the article page and then selecting "view source" in your browser. The meta tags need by Google Scholar are documented here: https://scholar.google.ca/intl/en/scholar/inclusion.html#indexing
Please only contact us if the meta tags on our end are faulty or incorrect.
