Thank you, so say for the West Brom match I would have previewed on Monday and reviewed the Spurs game on Thursday?
The other way around, so for simplicity, let's pretend that every game is on a Saturday.
Review = before a game
Preview = After a game
After the game, you need to get your
review video done asap, because by the time Wednesday comes, nobody cares anymore and you've lost the opportunity. Midweek is when fans care 'least' about football, and social media is at it's quietest, so the earlier you get your review done, the better.
Fans start thinking about the next game come Thursday evening, so your Preview needs to be ready, if you want it to have the longest shelf life, as come game day, it's irrelevant.
Each video you do is good for a few days only, so timing is crucial.
Think of it like a fresh sandwich - serve it when fans are hungriest as nobody wants a stale sandwich, nor do they want one too early after their last meal.
When are they hungriest?
Saturday - Game Day
Sunday - Still hungry
Monday - Reasonably hungry
Tuesday - Not really interested anymore
Wednesday - Nobody cares
Thursday - Any interest is now with next game
Friday - Hungry again
Saturday morning - Hungriest
If it were me, I'd do my Preview for the next game anytime Wednesday onwards, and my review Sunday, or Monday at the latest.
