Benefits of using Redirects
You can link the old pages to the new ones in case
Like any other business, yours too is likely to evolve and this must reflect on your website too.
You may modify your website or switch to a new platform. However, to retain your search engine placement, you will want to map the old URLs to the new ones.
Can prove very useful in Marketing
Imagine you are running an online marketing campaign and you send thousands of emailers to your customers and then you realize that the URL that should bring the traffic to your site has a typo error.
Well, worry not because you can simply redirect the erroneous link to your site and your customers will land on the right page.
Simplifies moving to a new domain without losing old traffic
For many reasons you may want to change your domain name. Educating all the existing customers who have been coming to your site using the older URL can be tough at times. Well, you can simply redirect all the traffic coming from your older domain name to the new one.
Redirecting from multiple domains
Some people have acquired many domain names and want to make sure they all lead to the same location. This is another situation where you can put a permanent redirect in place to easily guide your visitors and the search engines to the proper address.
