Ratio of linking C-blocks to Linking domains
-
Hi,
Our linkbuilding efforts have resulted in acquiring a high number of backlinks from domains within a C-block.
We all know Google issues penalties whenever someone's link profile looks unnatural. A high number of backlinks but a low number of linking C-blocks would seem to be one of reasons to get penalized.
Example: we have 6,000 links from 200 linking root domains coming in from 100 C-blocks.
At what point should we start to worry about being penalized/giving off an unnatural look to mr G?
-
I think you're overthinking the issue. The question is not the C blocks, but how it relates to your site. Are these links relevant? Are they using natural link text? Are you geolocated?
Remember that IPs are a technical thing, and while they count for some things, it's only one signal among many factors with your link profile.

Recently re-built our site and changed domain. Now I want to go back to old domain - it it a bad idea?
About a year ago I rebuilt our website and changed our domain name. We rent villas in Tuscany, we used to be 'invitationtotuscany.com'. Then I started doing the same in Provence, and in the italian lakes, so i had further sites called invitationtoprovence.com and invitationtotheitalianlakes.com. But maintaining them was awkward and I wanted to have one site. So I put them all onto invitationto.com and did 301s from the old domains and sites. Now I'd dropped off organic search results and I've also realised that invitationto.com is far less clear as a business address. My inclination is to go back to invitationtotuscany.com - Tuscany is still 80% of our business and have the other areas in there too - optimised for SEO for Provence etc. I'm being told its a really bad idea to change domain, 301 the old one, and then revert to the original domain. But I'm suffering anyway, so I wonder if I sjhouldn't just bite the bullet. A lot of my old good backlinks still point to invitationtotuscany.com (BBC, Sunday Times, etc) and the DA is 33 against 22 on the new one.. All help gratefully received! : )

How to redirect old domain to new domain.
We just recently signed up to Moz with hopes of fixing our Moz Ranking. We have an old domain - http://at-net.net and a new domain - https://www.expertip.net We have set up 301 (Permanent) redirects from all pages on the old site to the new, but aren't getting the ranking or aren't getting recognized from external links to the old sites. I've read the moz article on 'Link Juice' and followed those practices, but it doesn't seem to help. Does anyone have advice on doing this? Thanks in advance,

Blocking subdomains without blocking sites...
So let's say I am working for bloggingplatform.com, and people can create free sites through my tools and those sites show up as myblog.bloggingplatform.com. However that site can also be accessed from myblog.com. Is there a way, separate from editing the myblog.com site code or files, for me to tell google to stop indexing myblog.bloggingplatform.com while still letting them index myblog.com without inserting any code into the page load? This is a simplification of a problem I am running across. Basically, Google is associating subdomains to my domain that it shouldn't even index, and it is adversely affecting my main domain. Other than contacting the offending sub-domain holders (which we do), I am looking for a way to stop Google from indexing those domains at all (they are used for technical purposes, and not for users to find the sites). Thoughts?

Internal linking disaster
Can someone help me understand what my devs have done? The site has thousands of pages but if there's an internal homepage link on all of the pages (click on the logo) shouldn't that count for internal links? Could it be because they are nonfollow? http://goo.gl/0pK5kn I've attached my competitors opensiteexplorer rankings (I'm the 2nd column) .. so despite the face the site is new you can see where I'm getting my ass kicked. Thanks! psRsQtH.png

Too many navigational links
Hi there, I have an issue with the amount of internal links on my webpages. Moz campaign manager gives a lot of 'too many on page links' issues. Over 7000.
Technical SEO | | MarcelMoz
I know the importance of a good internal linking structure. 1. Not too many internal links (over approximately 100) is good for flowing through some authority from authoritive pages.
2. Too many internal links can spend all of the 'crawler budget' so the crawlers won't crawl the complete website anymore (right?). This can cause problems with indexing new webpages (right?). This is the situation: The website is a webshop The header contains 6 links, the footer contains 32 links, the homepage contains 42 links, the body content of some category pages contains a variated amount of links from 30 to a maximum of 100 links. Product pages do contain a maximum of 25 links. There is no problem here. Now here's the problem: The website navigation is a dropdown menu that contains 167 links to tier 2. These links are very important for our visitors. They can immediately find the right category/product by it. Removing or shrinking this dropdown is not an option. But the dropdown navigation is causing all of the 'too many on page links' issues. Question: is there a SEO (indexing, PA) problem in this situation which i should solve? What should I solve and how should I solve this? Note: pages have good organic positions and authority. Thanks a lot. Marcel0 -
Domains and Hosting Question
I bought hosting for unlimited domains on Godaddy. It's not a dedicated server. It was just $85 a year. I have unlimited latency but a limited amount of "space." I don't know a lot about hosting servers etc... My question is relatively simple. When I go in GoDaddy to my hosting. There is a site that shows up as hosted, and all of the other sites show up under that site in it's directory. If you type the name of the site I bought the hosted package on, then type a forward slash and the name of one of the other sites on the hosting package, you will actually go to the other website. What is this relationship? Is it normal? Does that make all of my websites subdomains of the main site (that I bought the hosting package on)? I don't fully comprehend how this effects everything...

External Links Discrepancy
Hello folks Apologies for my ignorance, but a SEO novice here… One of our competitors boasts over 300,000 external links, however when we analysed their links via http://www.opensiteexplorer.org we can only see around 10,000 in there “Number of Domains Linking to this Page” section. Can someone please assist and point out something which I assume is painfully obvious! Cheers, Chris

External Links from own domain
Hi all, I have a very weird question about external links to our site from our own domain. According to GWMT we have 603,404,378 links from our own domain to our domain (see screen 1) We noticed when we drilled down that this is from disabled sub-domains like m.jump.co.za. In the past we used to redirect all traffic from sub-domains to our primary www domain. But it seems that for some time in the past that google had access to crawl some of our sub-domains, but in december 2010 we fixed this so that all sub-domain traffic redirects (301) to our primary domain. Example http://m.jump.co.za/search/ipod/ redirected to http://www.jump.co.za/search/ipod/ The weird part is that the number of external links kept on growing and is now sitting on a massive number. On 8 April 2011 we took a different approach and we created a landing page for m.jump.co.za and all other requests generated 404 errors. We added all the directories to the robots.txt and we also manually removed all the directories from GWMT. Now 3 weeks later, and the number of external links just keeps on growing: Here is some stats: 11-Apr-11 - 543 747 534 12-Apr-11 - 554 066 716 13-Apr-11 - 554 066 716 14-Apr-11 - 554 066 716 15-Apr-11 - 521 528 014 16-Apr-11 - 515 098 895 17-Apr-11 - 515 098 895 18-Apr-11 - 515 098 895 19-Apr-11 - 520 404 181 20-Apr-11 - 520 404 181 21-Apr-11 - 520 404 181 26-Apr-11 - 520 404 181 27-Apr-11 - 520 404 181 28-Apr-11 - 603 404 378 I am now thinking of cleaning the robots.txt and re-including all the excluded directories from GWMT and to see if google will be able to get rid of all these links. What do you think is the best solution to get rid of all these invalid pages. moz1.PNG moz2.PNG moz3.PNG
