Hello, this is my first post here and i am new to SEO. Over the past few weeks i have been learning alot about SEO and one of the things i have learned is when it comes to blog commenting, it's best to find niche related blogs with a high pr as spamming low pr high obl blogs can be a waste of time. I've spent hours searching for weight loss related blogs and have used many methods such as blog finding tools and advanced google search with quotes such as (intitle: "weight loss" intext: "add a comment") or powered by. I can find niche related blogs, but the problem is none of them will let me post a comment. For example i type my comment and hit enter and it does nothing. The question i am asking is how do you guys find high pr, low obl auto approve niche related blogs? Thanks in advanced!
