On 15th of December 2021 a paper was published on www.frontiersin.org: “The Impact of the COVID-19 Pandemic on Avoidance of Health Care, Symptom Severity, and Mental Well-Being in Patients With Coronary Artery Disease”.
Frontiers is a leading Open Access Publisher and Open Science Platform with multiple peer-reviewed and editorial board led journals.
Neither Google, Bing nor DuckDuckGo did index it until today (24th of December). The paper was posted to ResearchGate on 17th of December. The ResearchGate page was indexed within days by Google, Bing and DuckDuckGo.
Now let’s see how long it will take the search engines to index this post (first published on 24th of December). To test this I will search for “Neither Google, Bing nor DuckDuckGo” and the paper title.
Update 26th of December:
