Does my "spam" site affect my other sites on the same IP?
-
I have a link directory called Liberty Resource Directory. It's the main site on my dedicated IP, all my other sites are Addon domains on top of it.
While exploring the new MOZ spam ranking I saw that LRD (Liberty Resource Directory) has a spam score of 9/17 and that Google penalizes 71% of sites with a similar score. Fair enough, thin content, bunch of follow links (there's over 2,000 links by now), no problem. That site isn't for Google, it's for me.
Question, does that site (and linking to my own sites on it) negatively affect my other sites on the same IP? If so, by how much? Does a simple noindex fix that potential issues?
Bonus: How does one go about going through hundreds of pages with thousands of links, built with raw, plain text HTML to change things to nofollow? =/

@Tom Roberts, your thinking is about on the same page as mine. I've always been suspect of "C-Blocks" as a ranking too. I don't use a CMS for this site, as I said it's all hard coded. Does the nofollow tag in the head section have the same effect as a nofollow on individual links? At least PHP could solve that issue pretty easily.

Hi Ethan
In theory - yes it could. We know that Google looks at a domain's Class-C IP level (at least - now that Google is a registrar it may extend to the full IP) when judging its quality. If a site is in a "bad neighbourhood" - ie sitting on an IP range with a number of 'spam' sites - then theoretically it could be affected, as a kind of guilty by association.
However, in reality I have some doubts as to whether this would happen. The fact is that the vast majority of the web uses shared hosting (particularly sme's) and so good sites are invariably always going to be mixed in with 'bad' sites. And what's stopping me from deliberately making a bad site on your IP in order to 'poison it'? I'm no way near that evil, but someone might be.
What I'm getting at here is that it seems extremely unlikely that there is a manageable way to differentiate these sites efficiently - which leads me to believe that having your spam site on the same IP as some 'good' sites _shouldn't _make a difference.
What you can do to reduce this risk even further would be to make sure the 'spam' site doesn't link to any properties of yours that you want to protect, to nofollow those links if feasible (not sure what CMS you're using but WordPress has a few plugins that would do this on bulk) and, if it isn't required, noindexing the site would pretty much get rid of all risk completely.
Hope this helps!

If you don't use the site in Google, you should noindex it just to clear up any potential issues (especially if the domains link together in any way.)

Download the full site and open all the pages in Notepad++. Find & replace. Save, reupload.

Hi Ethan,
I will say yes & no. Please watch below Matt cutts video on the exact issue.

Page with "random" content
Hi, I'm creating a page of 300+ in the near future, on which the content basicly will be unique as it can be. However, upon every refresh, also coming from a search engine refferer, i want the actual content such as listing 12 business to be displayed random upon every hit. So basicly we got 300+ nearby pages with unique content, and the overview of those "listings" as i might say, are being displayed randomly. Ive build an extensive script and i disabled any caching for PHP files in specific these pages, it works. But what about google? The content of the pages will still be as it is, it is more of the listings that are shuffled randomly to give every business listing a fair shot at a click and so on. Anyone experience with this? Ive tried a few things in the past, like a "Last update PHP Month" in the title which sometimes is'nt picked up very well.

Where did the "Location" go, on Google SERP?
In order to emulate different locations, I've always done a Google query, then used the "Location" button under "Search Tools" at the top of the SERP to define my preferred location. It seems to have disappeared in the past few days? Anyone know where it went, or if it's gone forever? Thanks!

How to create site map for large site (ecommerce type) that has 1000's if not 100,000 of pages.
I know this is kind of a newbie question but I am having an amazing amount of trouble creating a sitemap for our site Bestride.com. We just did a complete redesign (look and feel, functionality, the works) and now I am trying to create a site map. Most of the generators I have used "break" after reaching some number of pages. I am at a loss as to how to create the sitemap. Any help would be greatly appreciated! Thanks

How to block "print" pages from indexing
I have a fairly large FAQ section and every article has a "print" button. Unfortunately, this is creating a page for every article which is muddying up the index - especially on my own site using Google Custom Search. Can you recommend a way to block this from happening? Example Article: http://www.knottyboy.com/lore/idx.php/11/183/Maintenance-of-Mature-Locks-6-months-/article/How-do-I-get-sand-out-of-my-dreads.html Example "Print" page: http://www.knottyboy.com/lore/article.php?id=052&action=print

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?

Multiple Domains, Same IP address, redirecting to preferred domain (301) -site is still indexed under wrong domains
Due to acquisitions over time and the merging of many microsites into one major site, we currently have 20+ TLD's pointing to the same IP address as our "preferred domain:" for our consolidated website http://goo.gl/gH33w. They are all set up as 301 redirects on apache - including both the www and non www versions. When we launched this consolidated website, (April 2010) we accidentally left the settings of our site open to accept any of our domains on the same IP. This was later fixed but unfortunately Google indexed our site under multiple of these URL's (ignoring the redirects) using the same content from our main website but swapping out the domain. We added some additional redirects on apache to redirect these individual pages pages indexed under the wrong domain to the same page under our main domain http://goo.gl/gH33w. This seemed to help resolve the issue and moved hundreds of pages off the index. However, in December of 2010 we made significant changes in our external dns for our ip addresses and now since December, we see pages indexed under these redirecting domains on the rise again. If you do a search query of : site:laboratoryid.com you will see a few hundred examples of pages indexed under the wrong domain. When you click on the link, it does redirect to the same page but under the preferred domain. So the redirect is working and has been confirmed as 301. But for some reason Google continues to crawl our site and index under this incorrect domains. Why is this? Is there a setting we are missing? These domain level and page level redirects should be decreasing the pages being indexed under the wrong domain but it appears it is doing the reverse. All of these old domains currently point to our production IP address where are preferred domain is also pointing. Could this be the issue? None of the pages indexed today are from the old version of these sites. They only seem to be the new content from the new site but not under the preferred domain. Any insight would be much appreciated because we have tried many things without success to get this resolved.

Which pages to "noindex"
I have read through the many articles regarding the use of Meta Noindex, but what I haven't been able to find is a clear explanation of when, why or what to use this on. I'm thinking that it would be appropriate to use it on: legal pages such as privacy policy and terms of use
