The popularity of WordPress as a popular content management system all over the world. Because of this popularity, you may have created your blog at wordpress.com once. But if you want to take full advantage of WordPress, you will need to create a blog with your domain and hosting with wordpress.org downloaded from WordPress.org, not WordPress.com (wordpress.com). Because there are a number of limitations in Free WordPress, such as
1.Customization can not be done as it is said.
2.Footer credits can not be removed, so the website is not professional.
3.Using Google AdSense can not be earned.
4.The desired plugin can not be used.
5.Premium themes purchased from outside can not be used.
Finish the work of your website transfer. Now browse your site to see if there are any minor problems. Please try to solve it. Please tell me in the comments, I will try to solve.
If you want to redirect your WordPress to the new WordPress, you can take a paid redirect service. Due to redirection, visiting your previous links will be able to visit your new website which is a lot of work.
Congratulations on entering the world of professional blogging by transferring the website! Happy Blogging!
