that many links soo fast might not be a wise idea, spread them and build them through time.

very easy answer

I'd get a better plan than trying to promote 7000 different sites at the same time. As they say

"Jack of all trades master of none"

Spend a small fortune ... ftw ....

Why do 7k different domains EACH need 7k backlinks? Why 7k? Is there a new mystical google backlink formula involving 7k Ive not heard about?.

It can be done - it will take time and treasure ...

XRumer / Link Farm Evolution / Article Cartel Network / Lots of content / Lots of $$$ / Lots of SPAM / ScrapeBox and stuff ...

Maybe we can assist you by knowing a bit more about what your trying to accomplish.

I think you should think about quality rather than quantity.

1 link can be more powerful than 1000 links. It depends where it comes from.

There are various blackhat methods that will give you 7000 links by the click of one button but the number of links doesn't have anything to do with the level of success you will achieve.

Concentrate on getting links from quality sources and you will get better rankings quicker.

Remember you're going to have some 17-year-old whiz kid at Google finding your link chain and manually visiting your sites and evaluating whether or not to just blacklist all 7,000 sites in the flip of a switch. That many sites linked "together" with each other so quickly and unnaturally getting so quickly from "outside sources" will be two pretty big flaming red flags.

good luck with trying to get that many links in a relatively short period of time. Not sure if I would risk it. Take your time, and use services that are experts in that field and build at a paste that seems natural.

Remember the Hare and the Turtle.. the turtle usually always wins... slow and steady, I understand fast, however here in internet marketing land we have to be smart...

appreciate the answers and I always agreed with "Concentrate on getting links from quality sources and you will get better rankings quicker." but :

1.) it is a company I used to work for branching out for advice. I definitely do not own nor want to manage 7k sites.

2.) they have 7000 mini-sites w/ 3 to 4 pages each and want 1 link to each site to begin. it's their consensus. think bluewidgetssandiego, bluewidgetsaustin..etc. needing a link to each, (they came up w/ this strategy) and then to scale it up later on to 50....500+ for each one. Yes, quite a lot to do but not to junk spammy link sites.
I dont' agree with 1 link each to each site initially. I've built groups of 50, 100 or more sites at one time, and so on. But never 1000s of sites getting paltry links. Although they know what they're doing moneywise, as they recently sold off some properties in the multi$mil range to a Nasdaq internet community company.

GuerillaIM,

Yeah, I mentioned to them the footprint issue and making it look random rather than all the 1000s of mini-sites each getting a link or two from one site. 1000s of the mini-sites getting links from various sites. But if minisite sandiego is getting its link from a site w/ip address in massachusetts and minisite austin getting its ip(link) from a north dakota ip isn't it OK if they are all hosted on the same dedicated server.
Yeah, he told me they all share the same server. They mentioned brick-fish has this set-up and it hasn't hurt them.
So, far, I was thinking of the rapid index of using stat sites and plugging 100s of their domains in that way. Yes, I know that is spamming but I am seeking an ethical way of doing this.
what would Google do with 5000 newly owned sites with each not having 1 backlink.

Blog comment links sound like easiest and cheapest way to do it. Can automate whole thing with some software.

Probably buying one of those buy 7,000 directory links from an Indian guy for XXX dollars.

That's the fastest way I can think of.

I think it is a little risky.

You'd better spend more time on getting quality backlinks rather than getting 7k backlinks at the same time.
