I've had a network of 50 blogs for about three months, and I've been using:
in Settings -> Permalinks
I would like to improve websites performance in search engines and change it too http://domain.com/post-name . I have it set up this way in some other WP blogs.
All the websites are already indexed in Goolge and other search engines and when I change the settings to post name only and click on http://domain.com/2012/10/23/post-name in SERPS it gets me to an error page.
Can you tell me what is the best way to go about this one. I heard that I can use a rewrite rule that is gonna redirect the URLs to the right place. I definitely want to change it and strip the date from the URLs. I will be probably stripping "/category/" from URL slugs with Yoast SEO plugin also.
I want to change the URLs, make some other changes in the blogs, and submit sitemaps to Google and probably getting it reindexed again etc.
Please let me know what is the best way to go about this one.
