So I've been in the process of improving the SEO of a wordpress blog I took over at my job. As I have learned more I have wanted to change the permalinks. Originally the permalinks were all /year/month/day/postname/. First I changed them to just / postname/, but then I wanted to do a better job siloing. So a few weeks later I changed the permalinks to /category/postname/. I've tried the redirection plugin but it isn't working right, and the migrating permalinks plugin just manages to stop any link from working at all. I think I did something really bad, and I'm not sure to fix it.
Somehow, I think I've created some sort of tri-nested permalink situation that is a little out of control.
I want to stick with the /category/postname/ setup. My initial concern was the fact that all of my internal links were going to be linking to the wrong page. However now i realize that many of my google results are under the old permalink and get aren't found and just land on the main page --notably the /postname/ urls. But some, the /year/month/day/postname/ ones will link fine, but they appear to show up on the original URL and not my new /category/postname/ set up.
I have less than 50 posts so I'm willing to type out whatever .htaccess redirection code I need to, will this fix (A) the Google results problem and (B) the internal link problem?
Hope that made sense. I'm just beginning but trying to learn and fix what I screwed up.
Thanks.
