Hi Everyone, I have a wordpress blog and want to change the url structure a bit and want to make sure I don't fuck up my index/rank in google. This is what my urls look like now: /dogs/how-to-groom-your-dog/ /dogs/best-dogfood/ /cats/cats-are-masters/ /cats/cats-chase-dogs/ What I want to have: /pets/how-to-groom-your-dog/ /pets/best-dogfood/ /pets/cats-are-masters/ /pets/cats-chase-dogs/ So as you can see, I want to change the base portion of all the urls to a single one, and I am setting up a 301 redirect on all old urls to new ones. I have everything ready, can set the 301 and change the urls. My only problem is that I am unsure about sitemaps. My robots txt has a sitemap in it generated by a plugin, which updates immediately when I add/edit/change urls. So once I make the switch, the sitemap on my site will reflect that. Is it safe to go ahead with the migration and let google sort it out? Will the fact that new sitemaps will not have old urls cause new ones to be treated as brand new and will I loose rank? Do I need to somehow retain old sitemaps and submit both? Your advice is appreciated.
