Submitting to directories all at once? i.e. within the same week or 2?

[inhouseninja]

I have found a bunch of around maybe 20-30 directories that we seem not to be in, and that seem like they might be worth it from what I am reading…

My question is  - is it a problem to submit to this number of directories all at once – i.e. within the same week or 2?

Or should I think about spreading the submissions around a month or 2?

Just worried that Google etc might through a flag with a bunch of submissions all at once…

Thanks

Submitting to 20 or 30 directories should not have any negative impact at all. Another thing to remember is that the engines will not find these links at the same time anyway. They will be found when each of those pages are crawled which could be days or in some cases weeks and months. So no, no problems at all.

Any time clients ask me "What is a 'safe' link velocity?" I say - picture this - if it's something that feels like it can be achieved by a human manually taking action, then it's safe.

So if a human can submit to 20 or 30 directories all in a week or two that's safe.  Because that's what a full time marketer would do for any company.  It's when you instantly get hundreds or thousands of links from potentially shady sites that sets of the biggest red flag.And there's other signals that also imply "unnatural", which get factored in as well.

Truthfully, I've seen a site get tens of thousands of links in a single month and not have a problem.  Think about it - send out one piece of very good viral material, and BANG - thousands of links.
