Linkscape update tracking

[vinnyb2000]

I've got two questions really.  First, is there anyway to compare your current Linkscape updates with previous updates?  Second, I've made a concerted effort to gain accumulate links in strong performing domains over the past 3 months.  However, Linkscape does not seem to be finding those links.  Some of them are pretty straight forward, like Yahoo Directory (this went live last month).  Is there a lag time between when I link to a page and when Linkscape picks up.

Thanks,
Vincent

Hi Vinny,

In general LinkScape updates every 30 or so days. So if you gain a new link or 3 part way through LinkScape's cycle it's very possible that it will not be included in the most recent update. Also, as awesome as it would be if LinkScape's directory were as large as Google's, it isn't. This is mostly just due to technology constraints I'd guess, and not having dozens of ENORMOUS data centers like Google. Because of this there is a chance that some links will not be picked up (especially if the links might be on really new sites, or maybe rather spammy ones). So it really turns into a waiting game to see if those links you know exist are picked up on the next LinkScape cycle or not.

Finally, unless I've managed to totally avoid it this whole time, the index doesn't have any sort of history. The amount of data storage required to maintain such a history would be crazy in conjunction with how often they currently update their index. To name drop one of SEOMoz's competitors (sorry guys XD ) majesticseo.com does actually offer historic indexing services. I don't know how in-depth they are when you're fully subscribed, as I've never been a paying member of their services. It may be something worth checking out.

And if someone comes into this question and corrects me about SEOMoz having historic index access, definitely do that instead! I know I will =P.
