First off let me say that for me the most important thing about a Rank Tracker is accuracy.
And so far Wincher was my go-to pick in terms of accuracy and price.

Then this deal comes along and makes me wonder if I can move away from Wincher.
So I bought 1 code to test the waters.
Accuracy is ok but not perfect. Well, no rank tracker is of course, but Wincher is still more accurate than SerpWatch.

I could think about leaving a little accuracy behind me and move all my clients and projects over but the actual price to check let's say 100 extra keywords more after you have used all your keywords from the appsumo code is way too high compared to other tools like Wincher.

100 extra keywords tracked daily with Wincher: $3 per month
100 extra keywords tracked daily with SerpWatch: $16 per month

That's more than 5 times the price of Wincher and since we want to grow more and not stay stagnant I guess it makes no real sense from a financial perspective to switch over even though I like the GUI and some of the features.

The price gap here is way too high if you ask me.
I wish they had way lower prices for checking extra keywords daily then it might be a no brainer but if you get enough keyword by stacking codes than it might be a good deal for some for sure.
