Search Engine Indexing Limits
*Does not apply to websites with significant authority
This part includes common indexing limits imposed by search engines on sites that don’t hold a lot of authority.

Amount of links No more than 100 unique links per page
Title Tag No more than 70 characters
Meta Description No more than 155 characters
Parameters in URL
(No more than 2)		 Bad Example:
http://www.mysite.com/brands.php?object=1&type=2&kind=3&node=5&arg=6
Good Example:
http://www.mysite.com/brands.php?nike
Depth of URL
(No more than 4)		 Bad Example:
http://www.mysite.com/people/places/things/noun/danny/car
Good Example:

This part includes common indexing limits imposed by search engines on sites that don’t hold a lot of authority.

Common Canonical Homepage Issue
Bad http://www.mysite.com
http://mysite.com
http://www.mysite.com/index.html
http://mysite.com/index.htm
Good http://www.mysite.com/
To condense the four default homepages into one homepage, use 301 redirects (See table on right)
to correct for erroneous incoming links and make all internal links point to your domain using the
syntax ‘http://www.mysite.com/’. Always include trailing “/” on folders.

301 Redirect for Apache
Write to file called ‘.htaccess’. The file is named only as an extension.
Hidden files must be viewable in operating system. mod_rewrite must be enabled
Command Description
Redirect 301 /oldpage.html http://www.newdomain.com/newpage.html Redirect single file or directory to a new file or directory on a different domain
RewriteEngine on
RewriteCond %{HTTP_HOST} ^mysite\.com [NC]
RewriteRule (.*) http://www.mysite.com/$1 [L,R=301]		 Redirect http://mysite.com to http://www.mysite.com. Affects entire domain.
Entire site:
Redirect 301 / http://www.newdomain.com/
Redirect permanent /old http://www.newdomain.com/new		 Redirect entire domain to a new domain as either a 301 (recommended) or 302
This section includes the server side code for 301 redirects on Apache. 301 redirects on IIS are setup using the provided GUI and therefore were not included on this cheat sheet.
