      Hey Mozers,

      I see Moz has a reporting tool for C-blocking and for november I had 330.  Does this mean 330 Ip addresses came from the same location in the month of november?

        Ray did a great job explaining what and how linking c-blocks do to affect your domain authority. Generally speaking it is better to have unique linking c-blocks as it means a variety of sources are linking to your domain. If all come from the same c-block it may look spammy or fake according to search engines.

          In the Moz report it means 330 unique c-blocks that link to your website.

          It sort of an indicator of the diversity of your website's link portfolio.

            so what does the 330 mean then exactly? an average of 330 similar c-blocks ?

            is it an addition of total potential c-blocks

            100 c-blocks from A

            100 c-blocks from B

            100 c-blocks from C

              Correct, it is not telling you that you have 330 URLs from the same C-block.

                Ahh I understand the point your trying to make and I completely agree thanks for that.

                So the 330 c-blocks that i'm seeing in my report isnt necessarily telling me that I have 330 urls from the same c-block is it?

                  No problem,

                  Let's say we have 1000 domains linking to our website and...

                  • 800 links are coming from c-block A
                  • 150 links are coming from c-block B
                  • The remaining 150 links are all coming from unique c-blocks

                  Before looking at the linking c-blocks, we might think our effort of receiving 1k links is going well. However, after looking at the c-block analysis, we see that a startling 800 are coming from one c-block. It's very probable that many of those links' authority are being discounted because they are coming from the same 'source.' So, the 1k figure isn't telling an accurate story because many of the links acquired aren't really improving our SEO.

                  We should try and identify why so many came from 1 c-block and gain links in other areas. Maybe we targeted a location and specific niche which was part of a larger site network all hosted on the same C-block. We need to adjust our strategy to try and diversify out to more c-blocks, i.e. diversifying our portfolio of links coming in to our website.

                  Does that help?

                  http://moz.com/blog/ipv6-cblocks-and-seo This Moz post goes into some deep examples too.

                    I was following you until you said. "You want more linking C-blocks to your site and less links coming from the same C-block, in general."  that statement threw me off.  Could you explain?

                      I doubt there is a hard number of links per C-block to be considered 'too many.' It would depend on a lot of factors.

                      If your link portfolio is flooded with the same C-block then much of those links would be heavily discounted. A high number of links from the same C-block could indicate some sort of blackhat technique used on a specific web host, but not necessarily.

                      You want more linking C-blocks to your site and less links coming from the same C-block, in general.

                        ahh Thanks!.  What is considered as to many?  330 c-blocks seem like a lot of ip addresses from the same location

                          I believe that number is representing the number of different C-blocks linking to your domain. Not the total amount of links from those C-blocks.

                          So, it would mean that there were 330 'different' IP addresses. Different meaning that the C-block was different, the whole IP address differentiation could be a very different number.

                            Sure,

                            you could find an example in your dashboard under the following path

                            Links > competitive metrics > History

                              Ok, great - I didn't want to answer the question directly without looking at the report itself.

                              Can you let me know where in Moz you saw the C-block report? I'll check it out and report back.

                                Thanks for the quick response.  I have a pretty good as to how c-blocking works and what It is thanks for explaining though I do appreciate the help 🙂

                                My question was more so for the Moz tool.  It states that for the month of November I had 330 and I'm trying to get a better understanding as to what that 330 is referring to.  Would this mean My website had 330 websites that had similar c-blocks?

                                  Here is an example of what a C Block is:

                                  • 192.168.006.001
                                  • AAA.BBB.CCC.001-254

                                  So, the .006 in the above example is the C-block. Generally, IP addresses that have the same C-block are hosted by the same website hosting. For example, Hostgator, being a widely popular and cheap host provider, hosts a large number of websites in the same C-block.

                                  It's recommended to diversify a link portfolio and you want to increase the locations of where are links are coming from too. They may discount links coming from the same location, although they are not coming from the same website.

                                  Where was the exact location for the C-block metrics you're seeing in Moz?

                                    Hi Experts, I have done everything to come over the following metrics flagged as spam on my website by Moz, few months ago. But, Moz has not updated the spam score yet. ✓Low MozTrust or MozRank Score - improved from 2 to 4.5
                                    ✓Large Site with Few Links - My website have more than 6K backlinks
                                    ✓Small Proportion of Branded Links - My website have a good amount of branded backlinks
                                    ✓Thin Content - Every webpage on website has more than 500 words content
                                    ✓External Links in Navigation - There is no external link in navigation other than social media links
                                    ✓No Contact Info - The proper address has alreay been placed on website footer
                                    ✓Low Number of Pages Found - I am wondering if there are any standard score or number of links to reach to remove these flag?
                                    Also, please suggest some ways that will help me improve moz spam score at faster rate. Thanks for your help in advance!"

                                    Moz Bar doesn't show any data and keeps asking me to log in when actually I'm logged in.

                                    Hi all, I've been using Moz Bar for years. It ran well until about three weeks ago. It suddenly failed to show the DA and PA of sites that I open after I log in. And it keeps asking me to log in when I did. I tried to uninstall the Mozbar extension and reinstalled it several times. Nothing worked. I also tried to uninstall Chrome and clear the cookies, still, nothing changed. Did anyone experience this? How do you solve it and make it run on the track? Any information will be appreciated.

                                    Are we actually getting accurate data on keyword volumes from Moz (or other sources)?

                                    I have a client who does patio furniture repair and restoration. When performing keyword research in Moz for terms like "patio furniture repair" I see that only 11-50 people in the entire US are searching for this term according to the Moz data. However, running an Adwords campaign currently and our top keyword is the phrase match for "patio furniture repair" which has generated over 100 clicks in just a couple of months in ONE county. Is there a better way to research more accurate results on search volume estimates? This makes organic SEO and keyword targeting hard! Thanks, Ricky

                                    Has using Moz got me banned from Google search?

                                    Dear fellow Mozzers, For the last couple of weeks when ever I do a google search I have to enter a captcha code. Now I hardly use google anymore which is annoying ! Then I went onto support.google.com and saw this:   https://support.google.com/websearch/answer/86640?hl=en&ref_topic=3378866 "Automated traffic includes: Sending searches from a robot, computer program, automated service, or search scraper Using software that sends searches to Google to see how a website or webpage ranks on Google" Is Moz alone doing this? Thanks in advance for your response. Ash

                                    Hi The link to the hotel for Mozcon 2015 doesn't work - seems like its the 2014 link still in place. Thanks Andy
