This is because rankings can be misleading and ranking first on Google may not be that important: in fact, the highest ranking page in Google does not always receive the most visits.
How is this possible?
First of all, it depends on the organic CTR .
I’ll talk a lot more about this in the next db telegram step, but to give you an idea, Google result number 2 sometimes gets more clicks than result number 1. And if you can double your organic CTR, you’ve just doubled your traffic from that keyword.

Second, a single page can rank for thousands of different keywords.
Let's say you rank #1 for keyword A and your competitor ranks #2 for the same term.

But your competitor ranks #1 for keywords B, C, and D.

Because it ranks for more keywords, it will likely get more traffic on Google than you.
Bottom line: Monitoring your Google rankings is important, but the gold standard for SEO tracking is organic traffic.
