I'm working on a major update on one of my website after a slow but continued lowering in google search rankings. I went from 1/2 on my major pages to being at 3 or 4th position.
Currently my website is not realy structured, I added pages over years and it's basically all pages on the root directory, and a "/en/" directory for english version of each page.
I did add pages that are not exactly on my niche but close enough for me, and those are not ranking well. I was thinking that it may be a good thing to structure a bit my website such as : website.com/Category1/page1 website.com/Category1/page2
Also, I don't know if the way of putting the english version in a /en/ directory is a good way. The english pages are making almost all my traffic though.
Since I'm working on a major update, I thought that maybe it would be a good time to modify things up. But I don't know if that's worth the time or not. I checked different posts about that, and people seems to say it doesn't matter much.
