When to Stop Investing When it Comes to Ranking Videos?


During Episode 64 of Hump Day Hangout, someone asked about when to stop putting money in different optimization efforts for a video that has not been ranking.

The exact question was:

Does there come a time where you stop throwing good money after bad at videos that are still ranking on page 2 and 3? I have customers that are paying me $300 per month to rank videos and have done everything from optimizing videos, using silos as taught, setup a branded Tier 1 and 3 Tier 2 IFTTT networks around the channel, tried SAPE links with one (actually decreased rankings), purchased multiple contextual link packages pointing the Tier 1 IFTTT branded network, retweets, reblogs, video ads (in stream & in display), commented on high authority related videos with links back to playlist, etc. etc. Between the time and $$ being spent, I am losing and just wanted to know if there is a time to throw in the towel or is there still hope??
