Hi,

I have a blog on blogger. When I visit Search Engine Settings of my blog, there are two options which are disabled, both need to enable.

But, I have not enabled them because I want to know that Blogger robots header tags and robots.txt for SEO are optional or we need to enable it?

If we go to any blogger blog address for example: http://example.blogspot.com/robots.txt there is already one robots.txt so I think, I don't need to enable it.

Second thing is robots header tags. If we search on Google Images Blogger header tags there are many images with the same settings. Do I enable robots header tags or leave it disabled?
