Applied .htaccess for SEO
I have found .htaccess to be a great SEO tool. There are many how-to-guides about .htaccess and how to set them up. I am not going to outline how to set them up. If you want more information about how to set them up ask your server administrator, web professional, or don’t hesitate to contact me.
.htaccess File and commentary
There are several standard components but most of these I am using to try and prevent access. I also use the robots.txt standard to block Search Engine’s from indexing my portfolio.
The”order allow, deny” section with all of the IP addresses are listed to prevent spam and to deny total access from those IP addresses. Over time I have assembled these IP addresses from list, recommendations, and spam received. If you see that I need to add or delete an IP address drop me a message.

The “DirectoryIndex” section is meant to show which file should be called up as the root of the directory. You can edit this line to specify any file to be called as the root file for any directory.
DirectoryIndex index.shtml
The Mod Rewrite in this section is to rewrite file extension. Sample usages would be changing scripting languages from html to php.
RewriteEngine on
RewriteBase /
RewriteRule ^(.*)\.html$ $1.shtml [R=permanent]
The following is an interesting rewrite tool. This section blocks all of the listed agents to be redirected to a specified URL. If the agent is registers on this list I choose a blank domain for them to be redirected to. Agents, robots, Search Engines, or anything that isn’t human is supposed to register itself as an agent. In the data transmitted when they access a website includes part or all of the user agent names.
Most of this is based on information from forums and other websites. This is a pretty complete list feel free to use this list in your website.
