htaccess SEO

I'm going to show you some good htaccess SEO tricks in this post.
If you really want to get some good Page Rank then all the crawl errors that you see in te Google Webmaster Tools should be corrected.
Most of these errors are 404 (Not found) errors, meaning that there are link to pages in your site that doesn't exist anymore, maybe because the url changed or they were deleted.

With these htaccess SEO tricks you can easily correct some errors and improve SEO on your website

1. # Eliminate the /folder-name from directory from url
     RedirectMatch 301 /folder-name/ http://www.my-site.com/
    
2. # Rename the /old-name directory to new-name
     RewriteRule ^old-name/(.*)$ /new-name/$1 [R=301,L]
   
   
3. Feedburner redirect
   RewriteCond %{HTTP_USER_AGENT} !FeedBurner.*
   RewriteRule ^rss.xml$ http://feeds.feedburner.com/MySite [R=temp,L]
   
   
4. Setting preferred domain with starting with www
   RewriteCond %{HTTP_HOST} ^mydomain\.com$ [NC]
   RewriteRule ^(.*)$ http://www.mydomain.com/$1 [L,R=301]
   
   
5. Redirect to new domain
   RewriteCond %{HTTP_HOST} ^([^.:]+\.)*oldwebsite\.com\.?(:[0-9]*)?$ [NC]
   RewriteRule ^/(.*)$ http://www.mynewwebsite.com/$1 [R=301,L]
    
6. Redirect one single page (with no extension):
   RewriteRule ^my-old-page$ http://www.mysite.com/my-new-page [R=301,L]
   
7. Url rewriting: Rewriting yoursite.com/article.php?article_id=abc to yoursite.com/abc
   RewriteRule ^([a-zA-Z0-9_-]+)$ article.php?n=$1
   RewriteRule ^([a-zA-Z0-9_-]+)/$ article.php?n=$1
