I am not sure how many people experience my learning curve so when I first started out, I was tracking maybe 20 or so keywords when I first started using amztracker.
After playing around with the keyword tools, finding competitors keywords and using merchantwords, now I am pushing 100.
IMO there are probably 5-15 high volume, competitive KWs and then about 10-40 longtail KWs. Even still this is A LOT of keywords to track! Let alone to actively work on...
For those of you who have a bit more experience...
How many KWs do you guys typically track?
How many KWs do you actively work on to push ranking up?
Finally, typically when do you start to react when you see a KW ranking drop?
