How is a 301 Redirect Helpful ?
A 301 redirect enable you to send you visitor or the search engine to any replacement page you specify. A 301 redirect is also important because it's what's known as a permanent redirect. A permanent redirect is the one preferred by search engines so they are the only ones you should use if you want your website to be search engine friendly.
How Do I Setup a 301 Redirect ?
Basically there are two ways to setup a search engine friendly redirect. One is by directly modifying what's known as the .htaccess file found in the root directory of your website where your web pages are stored.
The second way is to use a software redirect script. The advantage of using a redirect script is that you can setup and maintain any number of 301 redirect 's through a control panel.
You can also do very clever and helpful things that will make your website even more friendly to visitors and the search engines, but more of that in the 2nd Part of this article.
Setting Up a 301 Redirect Manually
First let's deal with modifying the .htaccess file to setup a redirect manually just so you know what's required. Then I'll tell you a much simpler way to do this and a whole lot more.
First you must find the .htaccess file on your web server. There could be more than one, but you need to locate the one in the same directory as your web pages.
On some web hosts the .htaccess file is hidden, it's there but you just can't see it listed when you FTP to your host. On most web servers it's visible, so I'm only going to deal with the visible file. Download the .htaccess file as ASCII not Binary to your PC then open it with a text editor like Notepad or Textpad, not Word.
In the .htaccess file, type the following line but substituting your locations for the missing and replacement files shown in [ ] brackets, excluding the brackets.
Redirect 301 [relative URL of missing file] [complete URL of replacement file ]
Redirect 301 /directory/discover.html http://yourdomain.com/adventure.html
For every other redirect required you must add a new line of code to the .htaccess file then FTP to upload it as an ASCII file back to the same location you downloaded it from.
If all this sounds quite complicated, you'd be right, it can be, but life gets a whole lot easier in the 2nd part of this article Setting Up a 301 Redirect with Redirect Script Software.
