Whats in a (Afrigator) ranking?
by Stii
MyBroadband.co.za has done it again! For the second time this year, they’ve attempted to analyse various rankings of blogs to determine who is the top South African blogs. And they’re doing a stirling job at that, taking into account Afrigator, Amatomu and Technorati. Thanx Alastair ;-)
Now first off, let me state that there is in my opinion no right or wrong way of ranking sites. Every algorithm applied could be correct and if you’d ask the guys in the top 20, they’d favor the ranking system that they’re in, so this is not a debate of right or wrong, rather an explanation.
Amatomu goes about ranking their blogs purely on traffic. I.e. how much unique visits a blog gets.
Technorati gives you a rank based on links to your blog. The more links you have, the higher you rank.
At Afrigator we thought we want to make it a little more, uhm, interesting. Here is how we do it exactly:
First, we sort all blogs based on the amount of unique visits they got over the past couple of days. Then we assign a rank according to unique visits to each blog. For example (figures used are fictional in this example!):
We count the unique visits each site got the past couple of days:
iMod got 55000 unique visits the past couple of days.
Thought Leader got 45000 unique visits.
…my heart is in Accra got 43000 unique visits.
Black Looks got 42000 unique visits.
The effect is, according to unique visitors the above mentioned 4 sites are ranked:
iMod = 1st
Thought Leader = 2cnd
…my heart is in Accra = 3rd
Black Looks = 4th
Next, we do the same for page views, but lets imagine Black Looks gets the most page views:
Black Looks got 89000 page views.
iMod got 80000 page views.
…my heart is in Accra got 78000 page views.
Thought Leader got 69000 page views.
So according to page views, the sites are ranked:
Black looks = 1st
iMod = 2cnd
…my heart is in Accra = 3rd
Thought Leader = 4th
The next step we calculate, in a similar fashion to Technorati, the links to blogs from other Afrigator blogs. There are 2 types of linking we take into consideration:
- Links from blogs
- Links from blog posts
Let me explain what the difference is between the two.
Firstly, links from blog posts is simple. It is how many individual blog posts links to your blog, excluding your own posts. In other words, Mike links to my blog (or a post in my blog) in 5 of his posts. Justin links 10 times and Mark links 7 times. That is a total of 22 links.
Next we take links from blogs. In the above example, my blog is linked from 3 other blogs. I.e. I have 22 links from blog posts, but only 3 links from other blogs. Get the idea? Right, lets get back to our example.
The four guys get the following amount of links from blog posts:
Thought Leader has 255 links from blog posts.
iMod has 230 links from blog posts.
…my heart is in Accra has 190 links from blog posts.
Black looks has 186 links from blog posts.
This results in a ranking as follows:
Thought leader = 1st
iMod = 2cnd
…my heart is in Accra = 3rd
Black looks = 4th
We do the same again for links from blogs:
Thought leader is linked to from 57 blogs
iMod is linked to from 45 blogs
…my heart is in Accra is linked to from 37 blogs
Black looks is linked to from 35 blogs
Again, here is the ranking:
Thought leader = 1st
iMod = 2cnd
…my heart is in Accra = 3rd
Black looks = 4th
I just have to mention, links are only counted from other blogs being aggregated on Afrigator. If, for example, Techcrunch links to your blog, it won’t be counted as we do not aggregate them. ;-)
Right, now every blog has a position according to the 4 criteria mentioned:
iMod – Unique visits = 1st, Page views = 2cnd, Links from blog posts = 2cnd, Links from blogs = 2cnd
Thought leader – Unique visits = 2cnd, Page views = 4th, Links from blog posts = 1st, Links from blogs = 1st
…my heart is in Accra – Unique visits = 3rd, Page views = 3rd, Links from blog posts = 3rd, Links from blogs = 3rd
Black Looks – Unique visits = 4th, Page views = 1st, Links from blog posts = 4th, Links from blogs = 4th
What we do now is to calculate the average:
…my heart is in Accra average : 3 + 3 + 3 + 3 = 12; 12 / 4 = 3;
iMod average : 1 + 2 + 2 + 2 = 7; 7 / 4 = 1.75;
Black looks average : 4 + 1 + 4 + 4 = 13; 13 / 4 = 3.25;
Thought Leader average : 2 + 4 + 1 + 1 = 8; 8 / 4 = 2;
According to the average ranking, the sites are ranked:
iMod = 1st
Thought leader = 2cnd
…my heart is in Accra = 3rd
Black looks = 4th
And that, my friends, is the mystery uncovered. Pure rocket science, see? :P
If you go to the Blog stats page, you can see the ranking as per each of this criteria.
all those numbers made my eyes go squinty.
So in order to get to the top, you need a lot of traffic, incoming links from posts, and links from other blogrolls?

@ExMi hehe, reading it now, blegh, it does, you’re right :P
@Wogan nice try!
also, i think this answered one of the questions I asked here: http://expensivemistakescheapthrills.co.za/meme/afrigreator/
I assumed it would work along those lines, nice way of getting a good general overall rank compared to Amatomu, I like it!
Thanks for sharing this Stii :)
Pleasure Chris! BTW, when you coming for coffee and a tshirt?
You lost me near the beginning… can you just explain that again please?
Hehe – awesome. Thanks for that.
Thanks for this. Interesting insight.
I do have a question: As I understand it neither of the categories (pageviews, links etc) is weighted. So if blog A has the most page views – by a wide margin – but scores the lowest for the others it would end up at the bottom of the list. Is that correct?
Keep up the good work.
Hey Alastair,
That is correct yes. We’re looking on improving on it in the near future to incorporate weighting as it is a wee bit harsh as it works now. We’ll notify everyone when the weighting is implemented, but for now it works this way.
Thanks man!
Geez man, we must do that! Or grab some beers on the weekend, we are you working from, exactly, at the moment? I’m in Southern Suburbs for work, but still living on Roeland..
Can I come too? I’m lank keen for some beer and T-shirts ;o)
Thanks for the stat info. I’m forever comparing the Afrigator and Amatomu stats and thinking wtf!?
But, the first step, of course, is to make sure the tracking code is installed correctly in the first place, eish… :)
You lost me too – can you start over? No just kidding. I am always confused between page view and unique visits and I am afraid despite your detailed explanation – still confused but thanks for trying.
I came, I read this article, I coenquerd.

@Shaun yep, yep, you’re absolutely right!
@Funalaakie If you’re in Cape Town, why the hell not!? Get in touch…
@sokari Lol, thanks! Let me explain:
Unique Visits is every time someone visits your blog.
Pageviews is how many pages do your visitors open on your blog when they visit it.
For example: 3 people visit your blog. Each of them click on 3 blogposts of yours. That would mean you had 3 Unique visits and 3(visitors) x 3(pages they clicked) = 9 pageviews
Hope it makes sense ;)
Very interesting. Was wondering how it worked.
This makes Afrigator the best ranker then,even better than Technorati…
thanks for explantions
Anytime dude! Please do shout if you need any help.

Thanks for this, Stii. I found this very interesting and informative. :) Was just thinking about this and hey, here’s your post, explaining it. :)
[...] we run every 4 hours. (To find out exactly what the Afrigator ranking script does, see this post: Whats in an Afrigator ranking) Thus, every 4 hours, we calculate a new “score” or rank for each blog in our system. [...]
[...] you may be on top of the world at the moment, this may change again soon. We still believe that our Afrigator ranking algorithm is a good representation of a blog’s authority, thus the change is only temporary. [...]
My head, I think, just exploded. Wonder if google translator could help decode?
The Truth About Afrigator Rankings…
A recent temporary change in algorithm for blogs ranking by Africa’s most authoritative blogs aggregator attracted a lot of debate and suggestions. After complaints by bloggers, Afrigator soon made a formal announcement via their blog: Blog ranki…
I thought it was going to be some boring old post, but it really compensated for my time. I will post a link to this page on my blog. I am sure my visitors will find that very useful
