If you are one of those who is running their website or blog on WordPress then this can help you.
There are many ways through which you can post your blog on LinkedIn:
1. Through social sharing plugins on wordpress
2. Copy half of the blog that you have written and paste the content on linkedin posts or article section and make an anchor text to read more.
3. Use Chatgpt to rewrite the content in a new way and post in your account and give the link in comment so whosoever interested will read through that link.
You need to understand that no platforms like their users to get away from their platform so first give enough engaging content to attract users and then start giving your link.
