How many domains per IP
 

I mostly put 5 domains on a single IP address. How about you?

I don't unless they are just parked.

hundreds.. why waste money? ;)

Because of SEO proposes but good to know that 10 domains per IP is fine :)

thanks guys

You just pulled that number out of your ass...

As always, the correct answer is 42.

40-50-60 etc etc

IP space usage does not effect SEO much, if at all.

I've had 5 sites on the front page at the same time for the same term, ALL on the same IP. This was for a good sized single word, porn niche. I currently have a bunch of sites placed on front pages for a number of competitive adult terms, all hosted on same 4 IP's.

Blogger.com has thousands and thousands of well ranked sites all on its few IPs. Blogspot.com and tumblr do as well. i can name them all day long.

its a new age, stop believing everything you read on the internet about SEO.

if you own all of the sites on the ip and don't have to worry about someone else fucking it up then it's fine.

yup, same here.

If you are using the sites/blogs to gain ABC or ABCD hardlinks then you should spread them on as many IP's as you can, this will get you more trades from the same webmaster. While for the sites/blogs you are doing seo for the IP matters if your getting links back from the same sites in bulk. Not always, but very often Google will figure out whats going on and you could get screwed. However it's a little more complexed than that and if depends really on what seo strategy your on.

doesnt really matter, seo wise that is.

no proof of this ever.

seo and ip space spreading them out is just BS, these "SEO" hosting companies use this tact to get gullable people into hosting with them.

no solid proof anywhere of the benefits of this.

I have 4 virtual accounts that I spread blogs across...so about 20-25 blogs per ip.

Like said, if you want to gain a lot of hardlinks and in some case from the same webmaster/network the best solution is to spread your "trading blogs/sites" on as many IP's as you can. Thats what webmasters like to see. The same if your selling hardlinks.

Regarding The sites your doing seo on I personally tell who I work for to spread out on different servers their sites, one even moved a site to a hosting provider in easter Europe. Not that I think that it was necessary but he did.

I have noticed and I firmly believe that Google can trace via IP any seo activity, when it finds one it goes through the rest, it maybe a series of coincidences but since 2007 I have noticed that sites get slammed by Google in 2 or more at the same time or in very short time periods, these websites either were on the same Google analytics account or IP or bloth.

Like you said there is no solid proof of this, but here again every website that i have worked on I have taken these preventive measures and never had a problem with being sanded or key slammed, so I prefer to be safe/silly rather than sorry.

I link all my sites together on a single ip.

IP's dont mean SHIT. I have over 400 blogs and can tell you IPs dont mean shit for serps

I think we have like 19 now

When I wanted more IPs I contacted every well known SEO expert and the SEs themselves so I could quote them about IPs being interest for SEO.

Every SEO expert said the same thing - it doesn't matter one damg bit.

Just for what it's worth seo is not a legit justification to ARIN.

Every site we own has a unique IP address.

This is what people who sell SEO consulting would like you to believe. It's a myth.

If you can prove or demonstrate your assertion then please paste a source to some studies or research.

I am going to have to agree with you on this.

In the late 90's, early 2000's, I worked a lot with SEO companies and with companies doing SEO; developing software. Google has even said that IP address does not play a role in how your site is ranked.

To be quite honest with you, the best SEO that you can do to your site is done by following web standards and semantic coding. It's a shame that "SEO" has been saturated with garbage (like most things) and now a lot of people, even the so-called, "professionals" continue milking the pocket.

I would never pay a 3rd party for SEO.

As for how many sites I host on each of my IPs? For our incubator projects, I've seen no more than 3 active projects running on a single IP. Typically because during those times, there isn't much server load. Now, with large scale deployments, it's reversed in a way. We have multiple IPs for a single site.

That's because black magicians claiming to "know" SEO tell them they need separate IP addresses.

By SEO you mean spamming links ?

Google slams sites for not followings it's webmaster guidelines. The worse the departure from them the more you get penalized. It's all quite simple, Google tells us all what they consider best practice.

Actually you're just extending a fallacy. A myth fashioned by so called SEO experts to make them money.

You have no idea how I work but you call me a black hat magician a link spammer and that I lie to the people I work for to take their money. :thumbsup

As many as you like. It's about the content.

?

i have 7 different ips in use, 1 for mainstream, the other 6 for adult.
one of the ips has 19 domains on there and the sites rank higher than any of the other ip with less domains, so using 10 domains on a signal ip i think is crap but if you use shared hosting and the ip is shared out over 100s of sites surely if one of the other sites get,s reported as spam that will effect your site.

Agreed. It's not about how many IPs YOU use, but who else is using the same IP... :2 cents:

google can tell the difference between your site sharing the same ip with 30 other people, and knowing those sites are not yours.

Whatever IP my host sets up. Like fris said, it doesn't make a fucking bit of difference. Make any excuses you want but it will not change the facts.

Same Here :thumbsup :2 cents: :pimp

there are a lot of myths and google is a moving target. If anyone can come up with away to actually test all the myths I would be very interested in paying a lot of money for that information. Bottom line is you probably don't want all your sites hosted in the same datacenter with the same host.

I only really space sites across different IPs more to break up projects. Porn projects go on the set of IPs I have for porn stuff. Then mainstream projects go on their own IPs. After that don't spend that much time worrying about it.

At a time I was thinking it would help SEO wise. It never did anything more that I could tell. The best recipe for more SE traffic has been good content.

I built cheap mainstream sites from 2007 to 2008. I literally built thousands and thousands of websites and they were all hosted on a single IP. I am just going by what I have done and seen and I have never had a benefit from using multiple IP's. Each site was good or bad based on it's own merits, not what the IP address was.

that mirrors my experience as well.

Google has also publicly stated that shared ip's is perfectly fine.

DING DING DING! We have a winner!

10 max (now)
I used to put no more than 5.
Making tests with 15 as IPs are running out so it won't be as important as it was.

If you're saying he's being smart, then kindly explain how "I want all my sites on a unique IP" is justification to ARIN for address space ?

It amazes me how NOBODY who advocates unique IP's can show any evidence it makes a squat of difference.

says the guy SELLING IP SPACE!

ROFL!

funny how its always the people trying to black hat and backdoor their way into SEO that believe in all these magic sauces. Buy lots of links, pay ESL's to write lots of text, Buy more domains, buy more IPs, get in more data centers.... BLAH! Then when they get blacklisted, they always want to point to one step they forgot, rather then accepting it was probably one of the other "shortcuts" they took that got them cut. these kinds of projects are destined to fail from minute one, as all blackhat things are, slash->burn->repeat.

the only secret sauce is: make high quality sites.

you get out what you put in.

:2 cents:

I toyed around with blackhat for awhile but it was

$1 domain > 5000 keyword rich blogs created on autopilot based on keyword list > mixed content included blog posts that were pinged > listed in google blogs & other directories > make $400 in 3 weeks > get banned > repeat.

Of course I did more than one of these at a time. If you're going to spam do it right.

As SEO expert, guru and mastermind I can't say for sure.

I'll wait to see what the majority says and then parrot their opinion.
