Here is a quick example of showing you how I use the tool we build in 7 days to reverse engineer traffic sources and offers giving me great Traffic insights.
The tracking/redirect domain
I am going to analyse the default
That domain gets a massive amount of traffic. 100s of Millions of hits every month.
Traffic source
So where is the traffic to voluumtrk.com coming from?
Ignoring the direct traffic (no doubt referrer blanked), and google traffic, here are top top 3:
The Publisher
Lets look into that last one - alltube.tv - its not the largest adult site on the web, but it still gets over 10m visits every month.
What I like to do is look at its traffic and specifically where all the ads are sending traffic to.
Not by scraping, but by using actual human browser data - so real clicks & visits.
As usual with streaming and adult sites - we see bet365 at the top. Ill reserve that one for aother time.
The advertiser
Looking through the top 10 destination sites, (assuming I am in the gaming/download vertical) - clearly the first one that jumps out is we-are-gamers.com .
Look at that traffic spike in August!
The landingpage
Of the 30m in traffic, it looks like about 50% goes to the following page:
we-are-gamers.com/loa2/lp8
The data indicates that of the 30m monthly visits about 10% click through to the destination sites of the landing page. In the above case, about 23% of the 300k - so 70k visits to the offer.
The offer
So continuing our research - loa2.com - has about 4m visits in August.
we-are-games is the 6th larges source of traffic for loa2.
The main source of traffic is coming from an affiliate network - affiliaxe.com.
The network: affiliaxe.com
The offer id: 4918
From there if you want you can just keep going.
Next steps
So you can see above, by following the flow of traffic using real user/browser behaviour, you can uncover the broad outline of your campaign.
Hopefully you found this useful.

Used to do a similar stuff with SimilarWeb PRO, but they yearly package costs like $20k :-)
How do you get the data? Similarweb uses quite a lot of sources and partnerships to achieve what they can do. 
@azureus - why reinvent the wheel hey? So our product is based on data from a variety of data sources, including, in our opinion by far the best one, Similar Web.
Who'd interested in another case study?
Suggest a domain here and I will pick one from the posts tomorrow and add an analysis here
This is awesome!!!!
