what is enterprise seo in plain english?

Another way to put it to someone: on a small site you change a page, on an enterprise site you change a template and it hits fifty thousand pages at once. So mistakes are huge too. A lot of the work is testing changes on a slice of pages first and watching the results before rolling out.

Same SEO, just on a huge site with a lot of people involved. The hard part stops being keywords and becomes crawling and indexing tens of thousands of pages, templates that change thousands of URLs at once, and getting dev, content and legal teams to actually ship your fixes. half the job is politics, honestly.
