Welcome to WebmasterWorld Guest from 126.96.36.199
All three are on the same IP.
All three are using different styles of HTML coding and design. One site liks to both of the others. The other two don't link back.
If you want to use seperate IPs, you'll have to make sure they're all on different Class C blocks.
From their point of view, most people that launch 10 theme sites on the same IP are probably spamming, and so it is esier to just penalize all network sites that do so, regardless of the fact that some networks may be completely legitimate...G seems to be looking to really put the stop on spammers despite the fact they are penalizing some legitimate sites.
It isn't the end of the world to get 10 separate hosting accounts...I would definitely do it if there is any chance of penalty by G. That said, 10 accounts would be considerably more expensive and much more difficult to run. Advice anyone?
The layperson probably doesn't even know what an IP address is, and if they do it's unlikely they understand the reason why, or even know, that they should have one for their site. And I've seen a lot of laypeople running Frontpage sites that have a lot of good information on them. For whatever reason it seems that an awful lot of niches are dominated by this type of site, especially if there's not a lot of money to be made in them.
One of the only reasons I'd go with a dedicated IP for a site up to this point is to avoid getting banned if somebody else sharing the IP on my shared server decided to become a spammer.
Until this stuff about Google looking at whois to judge the value of a site, I wouldn't have even considered a dedicated IP to be an indication of anything but that the site administrator is tech-savvy.
Wouldn't you agree that most spammers probably tech-savvy? If spamming and other black hat activities are worthwhile, won't they all just begin using dedicated IP addresses? I trust they're making more than .50/domain/month, which is about what you can get dedicated IPs for.
As per your last point, I would say, yes most spammers are tech-savvy, but then again, being able to throw up 50 scraper sites on the same IP is pretty dang easy and cheap. 50cents for a dedicated IP on different c-block? Sticky-me w/your host...mine sure doesn't allow that.
There are so many good sites on non-dedicated IPs, I don't think Google would degrade them in the SERPs.
10 (related in theme) sites on the SAME dedicated IP (no site inter-linking) will G see this as spam?- Maybe a reason to go virtual.
Check sticky for my host.
having a dedicted IP for your site(s) sends a message that you are serious about the site.
I completely agree. A dedicated IP says "This site is important and well made"
I kind of wonder about that actually. I have a few sites that are just located on my ISP's web space that do extremely well in competitive niches. I can't help but wonder if Google sees a "hobby site" as something that's more likely to be informative and less commercial. I'm not sure I'd go as far as putting a decent site up on Geocities though...
However, if you take a realistic view (in SEO terms) it is unsatisfactory to have similar content on the same IP address because we have seen all sorts of penalisation due to duplicate content during the past few major updates (just look at the threads).
Whether it is correct or not it seems prudent to look at IP addresses (especially class C) as another criteria - and after all if you can visit these forums and gain an idea of what will remain acceptable to google or not.
Lets face it, what the user sees as duplicate does not seem the same as the search engines (after all a shockwave movie embedded in a html page at this time can not be accurately deemed duplicate or not after all so many other factors influence a human view of a web page).
So knowing this is it not better to try to keep the advantage in your court (whether in theory correct thinking or not?)
And if you share an IP address with others how do you know what content is on that?
I might think the major problem is when you have alot of sites on the same server and the same dns and you are crosslinking the sites. If you do it that i dont think its enough to just have diffrent ipīs then you need diffrent dns too.
