There's been a lot of talk in SEO about how personalized search affects the future of rankings, but it seems to boil down to one simple fear: does my client see the same rankings that I do? I decided to put this to the test...
This past week saw the launch of Google's real-time search and quite frankly everyone flipped out. And justifiably so, it's not often that our SERPs get torn up so much in a new way like this. Questions I'd love to see the answer to are things like: What triggers rea...
I'm a big Google fan - my wife often sleeps in their t-shirts, I speak on panels with Googlers all the time and I've even got a Google water bottle for working out (which happens all of once a month these days). However, I am NOT a fan of the Google link command, and I'm shocked by the number of folks who operate in and around the SEO and technology industries who haven't realized this. ...

Rand recently published a post discussing 17 ways a search engine values a link. His number 5 reason referred to Domain Authority and caused a little stir within the comments trail as to what Domain Authority actually meant and where the proof of its existence has been seen. The aim of my first YouMoz post is to provide an example of where ...

The blog post - PageRank Sculpting - from the head Google's Web Spam team is a critical read for SEOs worldwide: So what happens when you have a page with “ten PageRank points” and ten outgoing links, and five of those links are nofollowed? Let’s leave...
Google Authorization is a topic which crops up a fair amount in our day-to-day search wanderings. Not really because clients are asking if we're authorized but more because they always claim that previous SEO companies they received pitches from claimed to be Google Authorized SEO consultants. Unfortunately (fortunately?!) no such certification exists so we have to set them straight....
Today's article from Search Engine Land: Google Loses "Backwards Compatibility" on Paid Link Blocking & PageRank Sculpting is a must read, but it's frustratingly hard to understand Google's position shift on the topics. In this post I'll talk briefly about ...
Usually, I believe Google tries to act logically. Since I began researching SEO back in 2007, all of the theories made sense. So, as I approach new problems, I try to think them through logically and analyze why Google would do such a thing!

Tonight, as I was writing another blog post, I started working on a graphic that probably deserves a post and discussion of its own. Below is my personal opinion of how some of the key factors in Google's ranking system have changed through the years I've been in SEO: ...
Hello, I'm here today to talk about Google penalties. There's much talk and confusion in the SEO industry about penalties. We're always seeing in Q&A questions like: Do I have a penalty? Why do I have a penalty? How can I get rid of my penalty? ...
For many in the SEO field, Google's "sandbox," a filter the search quality team created to help fight spam, is a relic of days gone by. However, we've been spotting new cases over the last few years, and I finally found a great example to share publicly (and got permission from the site owner). Grader.com, and the four subdomains underneath it - Twitter.Grader.com, PressRelease.Grader.com, Website.Grader.com & Facebook.Grader.com - are all under pronounced effects that highlight this algorithmic element's impact.
