Yes, you can edit a blog post after publishing. However, depending on the blogging platform you are using, there may be some restrictions on what you can and cannot edit.
For example, WordPress allows you to make changes to the title, meta data, and body of the post, while Google Docs does not allow any editing after publishing. It is important to check the specific platform’s guidelines before making any changes to your post.
In general, it is best to avoid making major changes to a blog post after it has been published. If there are minor changes that you want to make, then it is usually safe to do so.
However, if there are major changes that you want to make, then it is best to wait until the post has been updated with the new information. This will ensure that your edits will be accepted by the blogging platform and will appear in the final version of the post.
