Ranking Tracking Tool Not Accurate?

[getbigyadig]

Is google still updating the algo on a daily basis or for the most part are you other mozzers seeing your rankings stick?  I ask because the rank tracking software I use locally on my laptop shows me inaccurate rankings, as well as the SEOMOZ tool (which was just updates yesterday). I am not sure why this is happening, but as of yesterday I lost four page one rankings, which I didn't deserve anyway, and was apparently a fluke until they did the PR update.  So I dont mind, but I am curious if they are still tweaking on a daily basis or if its safe to continue link building.  I dont want them to make another change and have it affect my rankings in a negative way.

Yes I am seeing things fluctuate.

Are they tweaking it daily?

I think they are always tweaking it, and now the webmasters are tweaking their sites more which is causing more fluctuations.

There are a few variables that would keep a software package from getting exact rankings, I know I use one. When in doubt I always check with a browser that I never click on anything with so that the results are not skewed.

I don't see a reason why you would stop linking building. If you have #1 #2 is going to try and get it back, or at least I would if it were me.

It would not surprise me if google is doing an intentional "shuffle" in some SERPs - just to test what searchers do with different rankings.

Oh that would be evil, especial just after another update.

Would certainly keep SEO's on their toes, and cause me to pull out more hair trying to rationalize some of the things I have seen over the past week.
