Anyone have experience with mass changing URL slugs for a website and its impact on google ranking and indexing? Looking to do it now for 151 pages, and I am getting mixed input from my google research 😞

I have such experience. If you do 301 redirect from old urls to new impact will be minimal. Google during indexing will be navigated to the new page and replace old page in index. Same for user flow. Same for traffic from organic search - user will be redirected to the new page

Thanks!

I recently did this. It hurt for a bit, but then we bounced back and got higher results. Also, you can't do it over and over again. Back link juice only goes as deep as 3-4 redirects.
