What are 301 Redirects?
If you have an existing website which you are migrating over to 3dcart, you can use 301 redirects to preserve your established URLs to your new 3dcart website.
A 301 redirect simply takes the entered URL for a requested resource and redirects the browser to its new location.
For example, let's say you have a product on your old store which was represented as http://www.yourdomain.com/product_A_.html. However, now that you're on 3dcart, that same product is listed as http://www.yourdomain.com/product_p_01.html or something similar. With a 301 redirect, visitors clicking or going directly to the old URL will automatically be directed to the new location.
This functionality can keep your rankings with the search engines by minimizing the amount of URLs on your site that come up as no longer valid.
-301 redirects will NOT work if you are switching to a different domain name.
To create your redirects:
You can also perform a CSV import of your 301 redirects by clicking on the Export/Import button located at the top of the page. More information on this function can be found by clicking here.
Beginning with version 8, your 301 redirects will also contain a section for unmapped pages. This is a small database of pages that were requested on your site, but don't exist. Since the pages are not available, they result in a 404 (page cannot be found) error message.
The purpose of this section is to let you see the pages that resulted in 404 errors, so you can make the decision whether you need tocreate a 301 redirect for it or not.
For example, let's say you have a product URL that normally reads http://www.yourdomain.com/widget-a.html and someone mistakenly goes to a misspelled URL like http://www.yourdomain.com/wiget-a.htm. Since the page doesn't exist on your site, it will generate a 404.
With the new "Unmapped Pages" section you'll be able to see the misspelled URL along with how many requests (hits) it has gotten. You can then determine whether or not it merits its own 301 redirect to the right URL.
To view/use the Unmapped Pages function:
The page will show you the unmapped URL, the number of hits it has gotten and a section where you can add the new mapped URL. As with the regular 301 redirects mentioned above, simply type in the filename of the new URL (you don't need the www.domain/ part)
