yeah for sure. i’ve seen sites take a serious hit from one bad move. one common one is messing up robots.txt or accidentally adding noindex to important pages, rankings can disappear almost overnight. i’ve also seen aggressive link cleanup hurt sites where people disavowed a ton of links without checking properly. another big one is changing URLs without redirects, that can wreck traffic fast. search is kinda unforgiving sometimes, one tiny technical mistake can snowball way more than beginners expect.
