The most dangerous bias in SEO is to think that any decrease in organic traffic was a Google update and any increase was self-made.
That’s self-serving bias.

Also dangerous:
When not ranking on a specific SERP: "Well you know organic traffic is complicated and there's a lot of nuance to what exact queries are driving traffic ... "
When ranking
#1
on that SERP: "Hey everyone look at this ranking!"
