Diggity Marketing Blog : SEO Testing Results & Case Studies - Part 2
What We Learned from 11 PBN Experiments

What We Learned from 11 PBN Experiments

In March 2017, there were changes in Google’s algorithm that greatly affected PBNs as a ranking strategy.

When I was running Diggity Links (now Rank Club), we would test every single domain before adding it to our network.

If a domain’s link caused a positive ranking increase when linking to a test domain, it was added to the network.  Otherwise it went in the trash.

Then, all of a sudden, PBN test success rates dropped down to disturbing levels.

Depending on the type of domain (expired vs backorder/dropcatch vs auction) pass rates got as low as 20% while, at the same time, as many as 50% of domains were toxic.

Yes, they would actually hurt whatever they linked to.

It was quite shocking but an interesting problem to solve, nonetheless.

What had Google changed?  And how could we turn this around in our favor?

My R&D director Rob Rok (also now at Rank Club) and I sat down and designed 11 test experiments involving over 300 PBNs.

This is what we found.

You’re about to learn the exact filters and factors we found that increased the pass rate and power of our PBNs.

A Complete Guide to Anchor Text Optimization for 2018

A Complete Guide to Anchor Text Optimization for 2018

(Updated for 2018)

Hands down, the most important skill you can have when it comes to offsite SEO is anchor text selection.

Having the correct anchor text distribution can make you (or break you) in the SERPs. If you do it right, you’ll find yourself at the top of page 1 and you’ll do it with less links than your competitors.

If you do it wrong, say hello to Penguin.

Not surprisingly, the most common question I get from link customers is: What anchor text should I use?

While I’d love to be able to answer this for everyone, but there simply isn’t a 5 minute answer.

Selecting the right anchor text takes analysis and practice, but there is indeed a methodical and repeatable process that you can use over and over to correctly optimize your site.

This is a skill that you want to craft for yourself, rather than rely on others for, so take the time to master it.

But let me just say… once you get this down, it’s like graduating to the next level of SEO.

In this article, you’ll learn:

  • How to find the optimum anchor text ratio to send to your specific site
  • 13 anchor text selection tricks that will give you an edge over your competition
  • How to balance internal anchor text ratios

Announcement: Rank Club Acquires Diggity Links

Announcement: Rank Club Acquires Diggity Links

4 years ago, I was sitting down with a business partner and we decided to sell links from our private blog network.

But if we were going to do it, we were going to do it right.  We wanted to change the game of PBN rentals.

We wanted to have the most powerful links, the most secure network, and the best customer service.

I tend to be modest with my accomplishments, but from what I gather, we’ve did a good job.

5 stars

Alas, it’s time for me to depart.

Diggity Links has been recently acquired by Rank Club, a new project launched by an investor group that I’ve worked with before in the past.
