I've been trying to rank an old site of mine. Started it in 2010, and I've let the ranking slip. So I decided to do some outreach and guest post on a bunch of DA50-90 sites. These are highly moderated blogs and online magazines. Not your typical guest posting sites. I've built quite the impressive list over the past couple months. If you were to buy these, it would have costed probably $2000-3000 in posts. I rode off my own name, experience and some guest posting tactics that have worked well for me. I didn't really experience that much movement. I didn't start seeing movement until I stopped worrying about DA and just got the most unique IP domains I could get. When it came to high quality guest post backlinks, it added trust flow but didn't effect rankings. When it came to referring domains, regardless of their metrics but rather just their overall quality, it helped the rankings. When it came to a private blog network with very low OBL, it started the movement. The PBN was my own, as I don't believe in renting links. For domains, I searched through my list of 12k expired domains to find some good .ca domains. With 10 huff post links on some of them, it really added the authority I needed. Anyways, back to guest posting... I now believe that a DA25 site that has almost no history of guest posts on its blog is more valuable in the SERPs than a DA60 site that has a history of accepting high quality guest contributors. Although every site needs a bunch of DA60+ links if it doesn't have them already, but there becomes a point where adding more just won't add any effect to your SERPs. Low OBL, low amount of previous guest posters and very targeted is what has worked before me. By targeted, I don't mean just your niche, but I mean your country. I'm trying to rank on Google.ca so I've been putting high weight on .ca sites. Sometimes it's as simple as searching this on Google: inurl:blog "contact us" your-niche site:.ca That will find blogs in your niche and country, with a contact form. If Google knows that the site accepts guest posts and reverse engineers the previous guest posters on the site that are in the same shoes as you, it will hold less value, regardless of how big or authoritative the site is. Also, once you hit that DA60+ mark, some of them are nofollow, such as SEMRush.com. Sure, it will keep the ratio natural but I wouldn't waste time on a SEMRush link again, even though people sell them for $300 like they're worth so much. The only nofollow links that I know hold true value are Wikipedia links. Anyways, I could have put this one my blog as an official case study but I'm too busy and figured it'd help a bunch of people out. I may go over my guest posting tactics later as a video. Some of this is fundamental but if you're not generating the traffic that you're worth, I'd reconsider how you're doing SEO for your site.
