      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
              190.245.111.230

              And these are different C-Class IP's:

              190.245.111.001
              190.245.222.001

              Google may assume that sites hosted in differnet C-blocks are more likely to be from different people.

                Redirecting an Entire Website?

                redirecting domain redirect former site

                Is it best to redirect an old website to a new website page by page to like pages or just the entire site all at once to the home page of the new site? I do have about 10 good pages on the site that are worth directing to corresponding pages on the new site. Just trying to figure out what is going to preserve the most link juice. Thanks for the help!

                Moz crawler is not able to crawl my website

                moz crawler

                Hi, i need help regarding Moz Can't Crawl Your Site i also share screenshot that Moz was unable to crawl your site on Mar 26, 2022. Our crawler was not able to access the robots.txt file on your site. This often occurs because of a server error from the robots.txt. Although this may have been caused by a temporary outage, we recommend making sure your robots.txt file is accessible and that your network and server are working correctly. Typically errors like this should be investigated and fixed by the site webmaster.
                my robts.txt also ok i checked it
                Here is my website https://whiskcreative.com.au
                just check it please as soon as possibe

                Adding https version of website: how best to redirect

                If I have 4 versions of my site http://www
                http://
                https://www
                https:// What is the best way to redirect without losing seo positions? i have been mainly using http://www but have recently added my ssl so https works also. I heard at Moz Con that I should get the https working. All of my marketing and ads are going to http://www 301 redirect 3 of them? Which 3? If https is becoming important, should that be my main url? will it hurt my seo to switch? Thank you so much in advance!

                Measuring the size of a competitors website?

                I think our website is too big, far too many indexed pages. I'd like to do some research on how big our competitors' websites are (how many indexed pages). Is there a way to do this? Cheers, Rhys

                How To Cleanup the Google Index After a Website Has Been HACKED

                We have a client whose website was hacked, and some troll created thousands of viagra pages, which were all indexed by Google.  See the screenshot for an example.  The site has been cleaned up completely, but I wanted to know if anyone can weigh in on how we can cleanup the Google index.  Are there extra steps we should take?  So far we have gone into webmaster tools and submitted a new site map. ^802D799E5372F02797BE19290D8987F3E248DCA6656F8D9BF6^pimgpsh_fullsize_distr.png

                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?
