I have been using Nozzle for since a few days now and I love the accuracy of this tool and how fast it detects the rank changes.

If you have used rank trackers before, it "might" be easier for you to get started with Nozzle. If you are completely new to rank tracking, take some time to watch their videos guides to make the set up process easier.

Being an enterprise level software it comes with a plethora of options - so it does have a learning curve. But the options are there for a reason - you can really fine tune exactly where and what you want to track.

Nozzel's works by taking snapshots of the SERP for the keywords you track, letting you know where you rank exactly.

It's makes it easy to determine who is your real competition is, by showing who all are ranking for the keywords that you are tracking.

Google PAA and Local SEO are other interesting features from Nozzle, which I am still testing, but I have heard great things about their PAA data.

Overall this is an enterprise level tool that comes at a fantastic price and is a steal at this price.
