I've just imported my blog from blogger to WordPress and I am running into few issues.
How to automatically set featured images to 400+ posts. I mean I want the first image in the post to be featured image. Manually setting it is time-consuming. Any plugin?
How to remove the category/tag "Uncategorised"?
I have changed the permalinks format of posts from the default blogger to default WordPress but I'm using Smart 404 plugin which automatically redirects most of the old post address to the new address, will it impact SEO?
Staying with number 3, how can I make it all old links work again. (I put some script from wpbeginner in functions.php but it didn't seem to work).
Thanks in advance!
