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,

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.

How do I "undo" or remove a Google Search Console change of address?
I have a client that set a change of address in Google Search Console where they informed Google that their preferred domain was a subdomain, and now they want Google to also consider their base domain (without the change of address). How do I get the change of address in Google search console removed?

Why do some URLs for a specific client have "/index.shtml"?
Reviewing our client's URLs for a 301 redirect strategy, we have noticed that many URLs have "/index.shtml." The part we don'd understand is these URLs aren't the homepage and they have multiple folders followed by "/index.shtml" Does anyone happen to know why this may be occurring? Is there any SEO value in keeping the "/index.shtml" in the URL?

How can I Style Long "List Posts" in Wordpress?
Hi All, I have been working on a list-post which spans over 100 items. Each item on the list has a quick blurb to explain it, an image and a few resource links. I am trying to find an attractive way to present this long list post in Wordpress. I have seen several sites with long list posts however; they place their items one on top of the other which yields a VERY long page and the end user has to do a lot of scrolling. Others turn their lists into slideshows, but I have no data on how slides perform against 10-mile-long-lists which load in 1 page. I would like to do something similar to what List25.com does as they present about 5-10 items per page and they seem to have pagination. The pagination part I understand however; is there a shortcode plugin to format lists in an attractive way just like list25?

Why crawl error "title missing or empty" when there is already "title and meta desciption" in place?
I've been getting 73 "title missing or empty" warnings from SEOMOZ crawl diagnostic. This is weird as I've installed yoast wordpress seo plugin and all posts do have title and meta description. But why the results here.. can anyone explain what's happening? Thanks!! Here are some of the links that are listed with "title missing, empty". Almost all our blog posts were listed there. http://www.gan4hire.com/blog/2011/are-you-here-for-good/ http://www.gan4hire.com/blog/2011/are-you-socially-awkward/

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?

What are the pros and cons of moving one site onto a subdomain of another site?
Two sites. One has weaker sales. What would the benefits and problems for SEO of moving the weak site from its own domain to a subdomain of the stronger site?
