Something I have been thinking about while learning technical SEO is that it is really easy to get pulled into fixing things that look important but do not actually move the needle.
On a large enterprise website there are always going to be a long list of issues flagged in any audit tool. Page speed, broken links, duplicate content, missing meta tags, the list goes on. And when everything shows up as an error it is tempting to just start fixing whatever is easiest or most visible.
But from what I understand, the most logical place to start is always crawling and indexing. If Google cannot properly crawl your pages or is wasting crawl budget on the wrong ones, none of the other fixes really matter. You could have perfectly optimized content and flawless Core Web Vitals but if the pages are not being indexed correctly they are essentially invisible.
So before anything else I think it makes sense to look at how the site is being crawled, whether important pages are actually getting indexed, whether crawl budget is being wasted on low value URLs, and whether there are any blocking issues in the robots.txt or through noindex tags that should not be there.
Once that foundation is solid then you can start working down the priority list. But skipping that step and jumping straight into meta tag fixes or page speed improvements on a large site feels like fixing the paint on a car that will not start.
Still getting my head around enterprise SEO but that logic at least makes sense to me.
