Setting Up of Redirects from Category to Custom Taxonomy

 

Once you have switched the categories to a custom taxonomy, the category archieve page will be showing the 404 error page. In this case there is nothing to be worried if the website is not live. However if the website gets live then the search engine might have already crawled the category pages and have indexed them. This would mean that those pages would already have been appeared in the search results and the users that have been coming from the search engine will be able to see a 404 error page.

For fixing this issue you will be required to redirect the users to the new taxonomy page for each category.

First and foremost thing you will be required is to install as well as activate the Redirection plugins. Once the activation is completed you will be required to visit Tools>>Redirection page. Here in the source URL field you'll be required to enter /category/.* and in the target URL field you will be needed to enter the custom taxonomy slug.



Now you will be required to check the box which is next to the ‘Regex’ option and then you need to click on the Add Redirect’ button. This will now be sending all category archive traffic to the custom taxonomy. You need to use this if you are not looking to use this categories at all.
