Well, here it is folks. The moment you’ve been waiting for.
The short story, for those of you who aren’t terribly interested in the details, is that the complete recalibration of the new Keyword Competitiveness score that uses Majestic data is now complete. When we rolled out the Majestic changes, we noticed that the KC scores were a little higher across the board, and we wrote this post detailing new recommended KC targets while we worked on recalibrating KC scores to align more with what everybody was used to.
This recalibration has now been completed, and those of you who’ve been with us a while and who are used to seeing the chart below can now go back to using that as the guideline for what keywords to target (i.e, KC 30 and under is low competition).
The more detailed takeaway here is that while the overall competition scale is the same between the newly recalibrated KC and the old Moz KC, the exact KC scores of the Moz and Majestic versions aren’t going to line up precisely.
A lot of the differences can be attributed to the fact that Majestic simply has a lot more indexed pages and backlink data than Moz. This means that for some sites, especially smaller ones, Moz may not pick up all the links that the domain or page have pointed toward it, or it may be missing data completely. As a result, the Moz metrics will sometimes underestimate the strength of those results.
Just as a quick initiation – the way that we calculate KC involves first calculating a ‘Base Page KC’ and a ‘Base Domain KC’. These two scores are then weighted and combined along with some other factors to produce the Keyword Competitiveness score that you know and love.
For those of you who really want to delve into the details, here are some of the changes we made:
- In the calculations for Base Page KC and Base Domain KC, we now weight Citation Flow slightly higher than we did previously.
- We increased the importance of the number of referring domains.
- We chose to weight domain-level information more heavily than we did previously. In both the prior iteration of KC and the old Moz KC calculation, domain-level information was only weighted very heavily when we had no page data available. In the new version, we introduce a tiered approach to weighting Base Domain KC where we adjust the emphasis of Base Domain KC based on the values of the root domain’s Trust Flow, Citation Flow, and the number of referring domains.
- Previously, if a specific page had no data, we ignored Base Page KC entirely and used domain data exclusively. This was a carryover from when we were still using Moz. With Moz metrics, there were actually many pages that didn’t have PA for us to use. Because Majestic has so much more data in their index, we’re more confident in saying that if a page doesn’t have data, it’s actually quite a weak page, and we’re happy to include the Base Page KC as a 0. This means that KC is now a combination of both page-level and domain-level data in all cases.
- We lowered the weight of URL targeting (i.e example.com/target-keyword).
Now that the recalibration has been completed, we encourage all users to follow the old KC guidelines again – basically, low competition is once again 30 KC or lower, and those with established sites can shoot for slightly higher targets.
