Rankz.io provides real-time rankings for any keyword in desktop/mobile SERPs to track your SEO progress. I have personally used this tool since their beta release and works like a charm every time.
Below are the details provided by Rankz while tracking an keyword.
VOLUME: The number of searches done for the keyword monthly. This keyword example shows that we can expect between 49500 searches a month for this keyword.
CHANGE: This will give you an overview of change in keyword rankings.
LATEST: This will give you the latest rank of that particular keyword in SERPs.
PREVIOUS: This will give you the previous rank of that particular keyword in SERPs.
BEST: You can see the best rank the keyword has ever achieved since you have started tracking it.
CPC: You can see the CPC of the keyword.
URL: You can see the absolute URL which is ranking for that keyword.
KEYWORD SUGGESTIONS: This will give you a list of related keywords that you can consider. Also represents scores from 0-100, with higher numbers being representative of better results. This number is a general overview of all the metrics and gives you a look at the keywords that have the most opportunity because of a higher search volume with lower competition.
EXPORT: You can export all your keywords into a CSV file by clicking on the export button.
Click on the login tab. Once you are on the login page you two options either by using username and password or by using Facebook and Google.
