At the Google Office Hours video conference, someone said their ranking disappeared after being advertised in Google Ads.
They said that after they stopped advertising, their ranking was reset.
What can the person ask to explain these events? The person who asked the question admitted that Google Ads should not affect the natural ranking.
Therefore, the essence of the problem is the factors that can affect the results.
Mueller explained the separation between search and pay-per-click (PPC) and then offered his views on this situation.
Correlations to Ranking Changes
Among the millions of companies that advertise on Google, it is not common for everyone, even most people, to experience a rise or fall in rankings.
The coincidence is what happened without a real causality linking them.
This is what happens when someone starts advertising and their ranking crashes.
Google will constantly update search rankings, and sometimes the effect appears to be a major event.
What happened here is probably just a coincidence.
