Search rank can sometimes not show up if
A) There are too many search requests detected by YouTube
B) An error occurred while retrieving search rank
To resolve this we recommend the following
1) Disable any extra YouTube extensions other than TubeBuddy
2) Wait 10-15 minutes and try again
3) Go to https://www.youtube.com/results?search_query=tubebuddy, if you get a Captcha prompt, fill it out and try again.
