Website owners recognized the value of a high ranking and visibility in search engine results, creating an opportunity for both white hat and black hat SEO practitioners. According to industry analyst Danny Sullivan, the phrase "search engine optimization" probably came into use in 1997. Sullivan credits Bruce Clay as one of the first people to popularize the term.

I think this sometimes gets lost in the SEO battle. We're trying so hard to earn the click to our site that we're forgetting that a lot of search experience ends right at the SERP itself, and we can optimize there too.
Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic.

Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
