What is the difference between a canonical issue and a canonical error?

A canonical issue arises when 301 redirects are not properly in place. This means that your website can be accessed by search engines from several different URLs. This means that search engines can then potentially index your site under different URLs, meaning that it will look like a site of duplicated content.

Canonical issue

A canonical issue arises when 301 redirects are not properly in place. This means that your website can be accessed by search engines from several different URLs. This means that search engines can then potentially index your site under different URLs, meaning that it will look like a site of duplicated content.

For example if you have the website http://www.example.com then the index page can be accessed from all of the following URLs:

http://www.example.com
http://www.example.com/index.html
http://example.com
http://example.com/index.html

.htaccess is a configuration file for use on web servers running the Apache Web Server software. When a .htaccess file is placed in a directory which is in turn 'loaded via the Apache Web Server', then the .htaccess file is detected and executed by the Apache Web Server software. These .htaccess files can be used to alter the configuration of the Apache Web Server software to enable/disable additional functionality and features that the Apache Web Server software has to offer. These facilities include basic redirect functionality, for instance if a 404 file not found error occurs, or for more advanced functions such as content password protection or image hot link prevention.

Redirects enable us to direct web site visitors from one document within your web site to another. This is useful for example, if you have moved your web site content and would like to redirect visitors from old links to the new content location.
