Following on from the recent blog post about hub scores and how they are changing, I wanted to do some analysis, mainly to satisfy my own curiosity as to how many hubs are reaching a certain hub score.
I created a standard deviation bellcurve, based on the bellcurve shown in the blog post; for the stats fans out there, the average score was 61 with a standard deviation of 14.
You can see the bellcurve below, although it's not identical to the one in the blog post, it's similar enough for some data to be drawn.
As you can see from this, hub scores range from around 17 up to 100, with the bulk of hubs scoring between 47 and 75. Based on this bellcurve, we can work out how many hubs are scoring at, below or above a certain threshold:
If the figures and bellcurve are too small to read, you can see them in a Google Doc that I have shared here: https://docs.google.com/document/d/1B0- … sp=sharing
So, what does this tell us? Here are the main takeaways:
- The average score for a hub is 61
- There are just over 1,050,000 hubs that have been assigned a hub score
- Based on monthly page views via Quantcast (28 million), if these were distributed to each hub evenly (which of course they are not) each hub gets on average 27 views a month; obviously, the page views are going to be skewed towards higher scoring hubs, but I don't have that data to hand
- We can also estimate the percentage of hubs that get a certain score or better; here are the key thresholds
- 77% of hubs score 50 or better
- 51% of hubs score 60 or better
- 25% of hubs score 70 or better
- 8% of hubs score 80 or better
- Only 1.5% of hubs score 90 or better
- Only 0.4% of hubs score 95 or better
Please feel free to add your own thoughts.
That is interesting to see, and helpful to see how our hubs are averaging.
You must be a brain Paul, that is impressive. Bravo!
Thank you Paul for being a brainiac and all your hard work! I am NOW feeling pretty happy with my hub scores.
If that is an accurate reflection of Hubpages ranking stats then either articles here are crap or Hubpages should improve their ranking system to better reflect a fairer bell curve rating system.
Just my opinionated opinion.
Two things stand out from the comments on the Hub Scores Distribution. Either articles at HP are crap according to Lorelei, or the Hub Scores are nothing more than readers response according to Relache. My view is that you may have the most stellar hub in town, if it attracts fewer readers you would have a low score. And so what's the relevance of the Hub Scores? To motivate you to attract more readers, that's what it's all about.
That is a good point and most likely right, Ben Aidoo.
I really have no idea why traffic was taken out of the equation. It is an important reflection on how well an article ranks on the internet overall. It seems that Hubpages will now be using a system which can be very open to personal bias. Most people largely write to earn just as Hubpages is here to earn or I am sure they would not be here. Targeted traffic generally equates to incoming revenue. Like I said at the start of this comment, I just have no idea why that traffic will now largely be removed from the ranking equation.
Great information, Paul! What's the math and Hubscore version of the phrase: "Steely eyed missile man," as used in Apollo 13?
Thanks folks - Although really, I was just being a math nerd to avoid starting on my taxes today...
Paul, this is because, as you've said earlier, the hubs are assessed relative to other hubs but if they are assessed relative to set standards of quality, this distribution will look different. If we are assessing relative to other hubs, this is useful in assessing how my hubs are compared to the others here in HP but is that a good measure of quality given that the real is out there in the much bigger world of search? Can HP use standards of quality and see how our hubs meet these?
Check the post on the admin thread that has the updated graph - it shows the new distribution.
HubScores do NOT mean anything outside of HubPages, and are not an accurate indication of writing quality at all.
They are a measure of reader response to your content more than anything else.
Good information to know. Thanks for doing the research and sharing that Paul.

Has anyone noticed a marked change in their hub scores? I only noticed today so not sure if it happened today or in the recent past.. But some of my hubs have seen a marked increase from 70's and 80's into the 90's and...

I posted a number of hubs the other day, which all started out at a relatively low score as they usually do--somewhere in the 40s and 50s. I saw my score drop a point or two, which I would normally see. Since then, the...
