Hello there,
Good day!

I am new in SEO world and newbie here. I'm just trying to learn SEO from such kind of informative sites.
I got an offer from one of my clients who wants to build dofollow links on high PR blogs through blog commenting. I got her website related to Apartments Rent and it's a .com.au website. Then i tried to throw backlinks on high pr blog post by commenting but most of the blogs rejected my links. I knew some comment policy. They didn't grant my client's website for backlinking.
Now the question- What types of blog will allow dofollow backlinks for my client's website and how can i find out these blogs? Can anybody please help me?
I'll be most grateful if anyone help me with a list of such blog.

With regards,
