Many suspect that the statistically abnormal link velocity is a key determinant in google flagging your site for artificial link building.

But if true, there are organic sites that have natural spikes in link velocity and they don't get flagged.

How would google differentiate between natural and artificial link velocity?

I would have to say that it would have to do with the types of links you are getting. There has to be some kind of quality-quantity distribution in this.

If links are coming in all kinds of forms at once, you pass the test. If they are all coming from a single or double source at once, you're toast.

natural spikes in link velocity

Natural spikes are perhaps more likely to be accompanied by online buzz from independent sources. Artificial link sources and artificial buzz are generally coordinated and I think are more easily spotted on a social web graph.

Common sense suggests that link building which proceeds faster than probable traffic would also show as unnatural spikes and raise flags.

In its Historical Data Patent, Google noted that signs of coordination accompany synthetic web graphs and intent to spam. At the time of the data patent, Google probably needed to rely on "spiky" anchor text patterns more than it does now. But to think of that merely as word matching is probably simplistic. Patterns of coordination on many levels can be spotted statistically.

For discussion of some broader natural patterns, see jmccormac's excellent post on normal link acquisition patterns in this thread... and also my reference to the Google Historical Data patent....

Most of my sites are seasonal and the links they get *always* come in spikes. Hasn't been a problem so far. But yes, they also accompany spikes in traffic, as well.
