There are a few ways to convert your Wix blog to a new blog. One way is to use a blog conversion tool. These tools allow you to keep all of your blog content, designs, and pages, and simply drag and drop them over to your new blog. Another way is to manually copy and paste your entire blog into a new WordPress blog.
This can be time-consuming and may not be ideal for every blogger. If you are looking for a more streamlined process, consider using a WordPress migration service. These services will take care of everything for you, from copying over your content to setting up custom posts and pages in WordPress. Once you have your new WordPress blog up and running, make sure to add any relevant SEO tags and links so that your new blog can rank well in search engine results pages (SERPs).
