Rankings-- Red & Green

[WalkieTalkie]

Question - you can see the green positive and the red negative. If I optimize a certain keyword, and it turns red - how long should I wait before I optimize it again? The same with green - I had a keyword ranking up 20 points...which of course is good...should just wait for a a few months or use the keyword again next month? Not use how I should address the ups and downs (green & red) of rankings. thank you..

So the colors are showing if the rankings are moving up and down. You obviously want to score as much green as possible.
For high volume keywords, I would keep a more close track of what's happening for them, for lower volume keywords you can likely come back after a few weeks or months as it's not worth the time spent on it.
