Make Facebook Page for Blog ?

You can choose to create a new page for your blog with your existing FB account. Both, your personal account and your blog's page will have different login credentials, but that page will be linked to your account so, you can switch accounts whenever you like. I think this will be easier than managing two separate accounts.

And please remove the link to your blog. This is against the forum rules, as including the link doesn't have any role in explaining your cause.

It is better to make a facebook page from your existing facebook account. The facebook page provides insights, people can like the facebook page you create, there are options to create various events/offers in facebook page whereas in facebook account you don't get such features such as insights, reaches of your certain posts. etc. There is option to boost your facebook page for likes over a specific area which is not available in facebook account. Moreover, facebook page signifies an authorised constitution of something while facebook account holds for identity of a person.

You can manage the facebook page with your existing account and need no other login for that.

So, considering everything, it is definitely better to create a facebook page for your blog.

Thankyou :)

 Thankyou :)

But...

if anything happened (page get block by facebook or many notifications) with my blog page will it affect my existing facebook account??? I dont want to take risk about my personal facebook account.

page get block by facebook 

Why will your page get blocked? 

Almost everyone uses the same account for their personal fb profile and blog fan page.
