I have been digging a little deeper in order to find out why the result in Market Samurai SEO Competition module has changed that much since MS start using Majestic as their data source.
From my knowledge about my own link building I would say that Majestic is 1-2 months slower to pick up a link than Yahoo.
They simply don’t have the same crawler capacity as Yahoo.
This is a steep back, but the way Majestic counts their links is a disaster.
For a new keywords I have a competitor. In the old Yahoo based Market Samurai he got a little more than 4000 links, however since Market Samurai start using data from Majestic he shows up with 1.6 mill links.
The funny thing is, that he has dropped down to 3 place.
Take a look at this tread and scroll all the way down. Backlink Count with Majestic SEO: What's going on here?
Here the marketing director of Majestic Dixon Jones explains how they count their links.
He mentions that they keep dead links for about 4 years and then he said “We do treat sub-domains as different (not internal) in some parts of our data set.”
This must be the key for understanding the 1.6 mill links mentioned above, since my competitors site is an old site with a previously very active forum in a subdomain.
A point here is that I start building links for my keyword based on a competitor with about 4000 links. In this scenario I have more than a fair change and I think this is still the case, but I would never have started a competition with someone who has 1.6 mill links.
I am really sorry to see this happen to Market Samurai. I hope they will find a way to fix the problems. Just 2 weeks ago I recommended Market Samurai to everybody, since it was one of my best tools.
