Welcome to the Q&A Forum

I have to change the permalink structure in wordpress, as using /%postname%/ in conjunction with a couple thousand pages triggers verbose rewrite rules, which further triggers about 5,000 requests per page load. The permalink structure must change as wordpress development probably won't change this in the near future. Now, changing the permalink structure worries me quite a bit, as about 25% of my traffic is attributed to my blog posts -- the rest is covered through CMS-like-use of pages (75%). blog posts will change permalink/url structure, pages won't The website is very respected in my niche and has quite a few links going to most of my posts and pages, as well as the homepage I've noticed in the last year that anything I post starts ranking on page 1 of Google for very competitive kws in 1-3 days, often with top 3 rankings PR4 / decent Alexa / Moz ranks not too shabby either / quality content / decent social media linking (mainly Facebook) / no penalties I provided the factors as to not gloat, but rather to get the best answer from those who have fairly established websites and perhaps had to change their URLs and noticed some or no changes to their rankings. How long of a hit am I going to take / how much my posts might drop down in SERPs if I change the permalink structure, properly 301 them, and implement all changes in one swoop? Info for WordPress users Benefits of changing the permalink structure to /%post_id%/%postname%/ -- for example -- include: way faster load times, not having 5,000 requests per page load, avoiding verbose rewrite rules trigger, finally modify the site without worrying about crashing the website and using a local server to make changes on thousands of pages (the database backups, the ritual of changing the settings in the local database, changing the post/page, saving the local database, loading the locally saved db on live server, and crossing fingers and pray it works -- just takes so darn long.) Ahh..yes, huge time saver. ** this issue occurs when using WP as a CMS with several hundred pages + and using the /%postname%/ or /%category%//%postname%/ or /somethingstatic/%postname%/ -- IF USING the date based way /%year%/%postname%/ or /%post_id%/%postname%/ you should be fine.

Below is my setup for redirects in .htaccess file in my root word press installation. The www to non-www works well, so no problems there Other page redirects work well, too (example: redirect 301 /some-page/ http://mysite.com/another-page/ (I didn't post those because I have a few too many : ) So here it goes... RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.mysite.com$ [NC]
RewriteRule ^(.*)$ http://mysite.com/$1 [R=301,L] BEGIN WordPress <ifmodule mod_rewrite.c="">RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]</ifmodule> END WordPress redirect 301 /archives/10-college- majors/ http://mysite.com/archives/10-college-majors/ redirect 301 /archives/10-college-%20majors/ http://mysite.com/archives/10-college-majors/ redirect 301 /archives/10-college-%C2%A0majors/ http://mysite.com/archives/10-college-majors/ I'm having a problem with the last 301 redirect: redirect 301 /archives/10-college-%C2%A0majors/ http://mysite.com/archives/10-college-majors/ not working... As you can see I've tried using other varations of the "space" but no go. I also used a redirect in cPanel's Redirect screen; testing all the possible options + wildcard I've also tried this: http://serverfault.com/questions/201829/using-special-characters-in-apache-mod-rewrite-rule (perhaps unsuccessfully, because it caused a 500 server error and it's a different situation in my case) I also saw something here: http://www.webmasterworld.com/apache/3908682.htm but I don't know if it works and how I would implement that + do so without compromising ALL other redirects. Note: the URL displays with a space in the address bar of all major web browsers: http://mysite.com/10-college- majors/  and goes to a 404 page I have a goregous page / PR6 / high authority site linking to the URL on my site, but they copied the URL with a space somehow. I contacted the person responsible for the website and he claims it works fine (aka he didn't check it). Is there a clean way to redirect ONLY this problematic URL without compromising other redirects, etc? Any ideas would be great. I'll respond with progress. Thanks in advance. UPDATE the   redirect works, and it did work. Even so, when looking at source of page linking to mine, the URL looks like this: ``` http://mysite.com/archives/10-college- majors/ Clicking the URL in Source View in FireFox takes me to ``` http://mysite.com/archives/10-college-%C2%A0majors/ none of my 301 redirects should direct there. I don't have any redirect plugins either.
