I have a couple of questions. First, which platform is your blog on? Wordpress, Squarespace, something else?
Second, what is your goal in sharing a blog post before it goes to general readership or Google? Are you wanting someone to proofread it, to look at the layout, to test the recipe, etc?
I did a quick Google search and it looks like there’s a way to publish posts on Wordpress that are password protected. I haven’t done it, but I’m assuming that means you could publish them then send the password to those you’d like to review it before publishing it to a general audience.
I have done sponsored work where I had to show the blog post before publishing. I can’t remember exactly but I use an plugin that created a preview link they could view for 24 hours that showed the post how it would look. I am sure what Taryn suggest would be a great option.
