It's been my experience that it isn't hard to rank for someones name. Do a video with your name first and what you do second in the title and it should rank on page 1 almost immediately. Make sure to put your name in the title of each post and video and maybe create a YouTube channel with just your name on it as well. You can back link the hell out of Web 2 assets like Blogger and Tumblr and YouTube videos seems to respond well also. Check the back link profile on the post that's giving you the problem. Use Majestic SEO or something similar. This will tell you how much work you need to do to push her off page 1. If the offending blog post has a lot of PA page authority you may have a bit of a problem. My guess is it probably doesn't. Just create 10 or more posts and videos of good content off your site, and then do some serious back linking. I outranked a lawyer with his name in the title of a hangout in less than 5 minutes. Once you figure it out, sell it as a service to leverage your knowledge. If you have any questions let me know.
Thanks... I have actually tried pretty much all of that. I made a youtube account with my name and uploaded a bunch of videos all of them with my name in the title. They didn't push the offending page down on their own. I tried to promote the pages with fiverr link pyramids and it didn't work. My Tumblr was flat out taken out of the search results (so I will have to go and do a link disavow.
The problem with using majestic seo (i've used ahrefs) is that I tried a negative SEO campaign so there are about 2400 backlinks, the overwhelming majority are from the link spamming.
Even my twitter, facebook and a blogger of mine is below the offending site. I really can't make much sense of it. It's just some regular person's blog.
