Question

I have a website that has been up for about 2 years now, it gained some search engine reputation over the time, and now I’m interested in using htaccess on it,
to rename things such as:

/index.php?act=Login
to simply
/Login

Now the problem is, that search engines will see both urls, and the login page is far from being the only url I will rename.
Which pretty much means that my entire website will have double the urls it has now,
What can I do to prevent it from causing damage to the SEO?

Is there some line of htaccess code I could use to redirect the old pages to the new ones as well? (I’m not even sure if that’ll solve the SEO issue)

Thanks in advance

Bottom line is to use R=301 (moved permanently) to inform search engines about your new URLs. For ex have your .htaccess code like this:

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

# external redirect using R=301 to /login from /index.php?act=Login
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+(index\.php/?|)\?act=login(&|\s) [NC]
RewriteRule ^ /login? [R=301,L]

# internal forward from /login to /index.php?act=Login
RewriteRule ^login/?$ index.php?act=login [L,QSA,NC]

With R=301 directive search engines will eventually start caching your new URI scheme instead of the old ones.
