You’ve been around the SEO block a few times, you’ll remember the day [not provided] was introduced. This was a dark day because SEOs seemed to lose a vast amount of trusty information, click data and conversions. This sort of information allowed SEOs to prioritize their targets.
According to Google, this information was removed for security purposes. On the other hand, SEOs felt that this was a push towards spending more on AdWords.
But either way we’ve moved on. Then a few years later, Google Webmaster Tools (now Search Console) started providing some of the keyword data in the Search Analytics report. Through the years, the report got better and better.
There’s still a finite set of keywords in the interface though, as you can’t get more than 999 in your report.
