Hello everyone, as you know, when we track the ranking of a keyword, the order of the returned results can differ when re-querying from different extensions or different computers. Because of this, I generally use the IPs used in SEO contests, but I am unsure if this is how we get the most accurate result, so I wanted to ask you as well.
Do you check the rankings by repeatedly clearing caches, or do you have a specific IP you use?
I check using Google’s Search API feature. I don’t deal with clearing cache or other IP inputs at all; it is effortless because Google sends JSON data directly.
I would appreciate it if you could write how to use this. It looks like something very useful. 
There is a Premium SEO Pack plugin made for WordPress that has a SERP control feature; you can add any keyword to the system to track it with any URL you want. I use it that way. Also, a program can be written for the Search API, etc.
