Customize the frequency of how often to track and report.
If you are planning to track thousands of keywords for multiple domains frequently, then its recommended that you use proxies. Otherwise you hosting provider might have issues with your site.
You can either scrape and use free proxies But i suggest you get a couple of private proxies which should cost you just $2 - $3 month and use them so that your hosting account remains safe.
For the Basic package I will be using a free plugin You can do your search and find this plugin and do this yourself. I just save you the time and effort of installing it and setting it up for you.
For the PRO package i am using a premium plugin.
