I want to change my site URLs into meaningful ones, but many of them have back links from other sites. Will changing URLs will affect my back links or my indexing?
What is the best way to do this redirection, given that the site is huge (+40,000 pages?) The old site is built with pure PHP as well as the CMS built in house using MySQL database. We are building a new website in pure PHP and the CMS in Laravel.
Both websites follow the same structure.
