How to Enable SEO URLs On OpenCart

Login to your OpenCart admin panel.

• Navigate to System > Settings and click the "Edit" link.
• On the "Server" tab, set "Use SEO URL’s" to "Yes" and save the changes. 
• Connect to your server via FTP using any FTP client (e.g. FileZilla)
• In your main OpenCart directory, there should be a file called .htaccess.txt. Rename it to .htaccess. If you already have an .htaccess file, add this code at the end of the file: 

# SEO URL Settings RewriteEngine On # If your opencart installation does not run on the main web folder make sure you folder it does run in ie. / becomes /shop/ RewriteBase / RewriteRule ^sitemap.xml$ index.php?route=feed/google_sitemap [L] RewriteRule ^googlebase.xml$ index.php?route=feed/google_base [L] RewriteRule ^download/(.*) /index.php?route=error/not_found [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} !.*\.(ico|gif|jpg|jpeg|png|js|css) RewriteRule ^([^?]*) index.php?_route_=$1 [L,QSA]
If your store is in a separate directory (e.g. "shop"), open the .htaccess file in a text editor and look for this line:

RewriteBase /

If your shop is installed in a directory called “shop“, for example, change the above line in the .htaccess file to:

RewriteBase /shop/

Remember to put the slash (/) at the end. Otherwise the SEO URLs will not work with OpenCart. Adding SEO keywords for your products and categories
Note: The default OpenCart SEO URL functionality doesn't work with multi language multi shops. You'll need to install an extension for that.
Note 2: Do not use spaces in your keywords. Use only unique SEO keywords. You cannot use the same keyword for a product and a category.

1. To add SEO keywords for your products:
2. Go to Catalog > Products
3. Click "Edit" for a product
4. On the "Data" tab fill in the SEO keyword field 



5. Go to Catalog > Categories and repeat the process for your categories
