Bwrite redirects generator creates 301 redirects for you

Be it due to the migration to a new webspace, a website relaunch or a content audit, web developers and system administrators are often asked to add 301 redirects to a website’s .htaccess file.

Yes, we can all add 301 redirects to a .htaccess manually. Yes, it’s much cooler to write some “code” than use a tool. But let’s be honest: Once you get a friendly request from your SEO partner to quickly add a “few” (usually meaning: many) redirects, you’ll love the bwrite 301 redirect generator:

Compared to many other free htaccess generators, the bwrite tool convinces with its easy-to-use user interface. In our opinion, it’s the fastest tool to generate many 301 redirects at once. Just add the old URLs in the left column, paste the new URLs in the right column, and click “Generate .htaccess code”. Copy the result, add it to your .htaccess and – voila – you’re done.
