Websites on same c class IP address
-
If two websites are on the same c class IP address, what does it mean ?
Does two websites belong to the same company ?
-
But if you have 20 sites linking to you, and they're all from the same Class C IP address, and those are pretty much your ONLY links, that looks a bit fishy to the search engines. It's a signal to the search engines that "hey, this person can only get links from sites that have a high probability of the same person being in control of all of the sites".
That's why you'll see people talk about linkbuilding and wanting to do so from different Class C IP addresses.

Not necessarily. f you see different C blocks, you are usually talking about two different webhosts. So there is a chance that different sites from one owner are hosted in one C-block.
Even an IP-address is not always used for one company. You can have your own IP-address which leads to your website. But providers can also share an IP-address for different domains/ websites for different companies.
To find if website belong tot the same owner you need to check te registars database or tools like allwhois.com.

Thanks Olaf.
So, does it mean that sites hosted on same C class IP belong to one owner ?
-
A "C" Block address is based on your IP address.
For example 190.245.111.001 is a standard IP address. The c-blocks in this case are: AAA.BBB.CCC.001-254
So these are within the same C-class:
190.245.111.001
190.245.111.230And these are different C-Class IP's:
190.245.111.001
190.245.222.001Google may assume that sites hosted in differnet C-blocks are more likely to be from different people.

Two websites, one company, one physical address - how to make the best of it in terms of local visibility?
Hello! I have one company which will be operating in two markets, printing and website design / development. I’m planning on building two websites, each for every market. But I’m a bit confused about how to optimize these websites locally. My thought is to use my physical address for one website (build citations, get listed in directories, etc. ) and PO Box for another. Do you think there is a better idea?

Duplicate Version of My Website
Hello Again, Looking for a little help to help me understand what exactly is going on here. Ive taken over maintenance of a website and have so far fixed a lot of issues. ahrefs has shown me that a second version of my companies website exists that exists at a second url. This second website is linked to the actual company website like I haven't seen before. www(dot)#(dot)co(dot)uk is the main company website. But a second accessible version exists and is accessible at www(dot)#(dot)co(dot)uk The instruments version is a direct copy and all of the links point directly to my main site. Any changes I make on the main version are automatically applied to the other version. It shows up as a SPAM back link on moz as all of the link points to my website etc Ideally in my mind, the instruments version homepage should simply re-direct to the main homepage to solve this "duplicate content and spammy backlink" issue however, the instruments version is the same suffix that all our company emails work with. Basically, HELP lol. I have no understanding of how this is set up, and the best way in which to deal and if it could affect anything such as company emails.

How to SEO a Website Built off Godaddy?
I have a client whose website is built off Godaddy services. I know Godaddy is not the right choice for building a website, but what's done is done. The client has already bought the Godaddy services and there's no way I can tell him to go rebuild his website before we could optimize it for SEO. I'm already facing a lot of challenges while optimizing on-page elements. When I wanted to verify the ownership for Google Analytics and Webmaster Tool via his Godaddy account. the process failed many times. it looks like Godaddy is using some kind of caching not allowing us to modify the codes. For example, I'd applied the site verification codes for Webmasters Tool 48 hours ago, and the metatag for google site verification is not yet updated in the frontend. It's quite frustrating. What would you suggest?

How do I resolve Twin domains? redirect website.com to www.website.com?
I am new to this website. Tried to run a campain and got a warning that website.com resolves to www.website.com which hinders SERP by competing for Keyword indexing!. (website is my domain name) Would appreciate help with this. Thanks. S.H. PS: here is the exact wording of error : We have detected that the domain www.yfvaccine.com and the domain yfvaccine.com both respond to web requests and do not redirect. Having two "twin" domains that both resolve forces them to battle for SERP positions, making your SEO efforts less effective. We suggest redirecting one, then entering the other here.

On a dedicated server with multiple IP addresses, how can one address group be slow/time out and all other IP addresses OK?
We utilize a dedicated server to host roughly 60 sites on. The server is with a company that utilizes a lady who drives race cars.... About 4 months ago we realized we had a group of sites down thanks to monitoring alerts and checked it out. All were on the same IP address and the sites on the other IP address were still up and functioning well. When we contacted the support at first we were stonewalled, but eventually they said there was a problem and it was resolved within about 2 hours. Up until recently we had no problems. As a part of our ongoing SEO we check page load speed for our clients. A few days ago a client who has their site hosted by the same company was running very slow (about 8 seconds to load without cache). We ran every check we could and could not find a reason on our end. The client called the host and were told they needed to be on some other type of server (with the host) at a fee increase of roughly $10 per month. Yesterday, we noticed one group of sites on our server was down and, again, it was one IP address with about 8 sites on it. On chat with support, they kept saying it was our ISP. (We speed tested on multiple computers and were 22MB down and 9MB up +/-2MB). We ran a trace on the IP address and it went through without a problem on three occassions over about ten minutes. After about 30 minutes the sites were back up. Here's the twist: we had a couple of people in the building who were on other ISP's try and the sites came up and loaded on their machines. Does anyone have any idea as to what the issue is?
