Hi

I am new at this place. I have query related to directory submission.

1. Two different site on the same ip Is it ok from SEO point of view or should they all be on different class c IP network?
Or is it safe to put them all on the same class C?

2. Search engine doesn't like same class ip sites? If we will submit our site on the same class ip's sites what will happen in that case?

3. What is Class C Duplicate and Subnet Duplicate??

I hope i will get the best possible answer soon !!!

Thanks

Hiten

Welcome, Hiten

What it comes down to owning two or more sites and whether you want the search engines to be aware of that. If they're on the same class C IP, it's easier for them to figure that out, so cross-linking them becomes more of an issue. But keep in mind that

1. Google has access to your registration data
2. and cross-linking two sites, especially if they're not directly related, is kind of obvious anyway

In other words, I really don't see a reason to worry about it unless you've got something to hide. If you do, sharing a class C is just another piece of information. They can figure it out without that clue.

Hiten, what does this have to do with directory submission? Directories definitely don't care about your c-class and IP.

I think its not really a big deal.. Haven't really seen any sufficient info to prove that IP's make a great impact on SEO

My answer when asked this is "If it does matter then the budget web hosts with hundreds of web sites all on the exact same IP address are going to go out of business soon."

i see alot of obsessing about class C but thease days the intertubes actuaualy use somthing called CIDR Classless Inter-Domain Routing so a hosting company will have a block or block of IP addresses that will normaly be adjecent - but it wont be a class C address

so Google can tell what supernet(a site belogs to) or isp a site is hosted at or who own's that bit of teh IPaddress space. But how this could be safely used to mark sites down as you could not be sure that all sites on an IP are bad - how eaver certain email spam vigilatees do do this - one famously blocked an entire class b range in australia.

I would suspect that G Y and MSN are a bit more savy than that - they must have a few CCIE's on the staff

We have done very, very extensive testing on this subject and have struggled to prove that there is any kind of obvious penalty when cross linking sites on the same IP address. There are many other factors that affect rank much more heavily.

IP Classing ceased to exist BEFORE Google was even thought about! That's how ridiculous the "experts" can be.

The IETF published the CIDR RFCs in 1993, 5 years before Google made it's debut, so why the numpties think that they put emphasis on something that didn't exist even at inception time is beyond me.

It's like the 'experts' consulting to our parent company requiring every site we own to be on a different (sequential and adjacent) ip address to improve SEO benefits. I had a red mark on my forehead all day after hearing that one.

ROTFL
