Why would a site (competitor) show up in Keyword SERPs Analysis but not show up in Rank Tracker for the same keyword?

I used Rank Tracker to evaluate a specific site for "geofencing software" - the result was "not in the top 50." However, if I go to Keyword SERP analysis and put in the same keyword "geofencing software," it shows the specific site within the first page results in SERP. I verified the ranking with a google search of my own and the site does show in the first page results.

Why is Rank Tracker not matching Keyword SERP results?

Google is much quicker to index than 3rd parties. It is most likely a lag in the rank tracker.

Keep in mind, SERP results change multiple times per day and URL's are always shifting rankings. If it doesn't show up in the next few days comment again on this thread and ill see if I can help further!
