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.

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?

Mobile site ranking instead of/as well as desktop site in desktop SERPS
I have just noticed that the mobile version of my site is sometimes ranking in the desktop serps either instead of as well as the desktop site. It is not something that I have noticed in the past as it doesn't happen with the keywords that I track, which are highly competitive. It is happening for results that include our brand name, e.g '[brand name][search term]'. The mobile site is served with mobile optimised content from another URL. e.g wwww.domain.com/productpage redirects to m.domain.com/productpage for mobile. Sometimes I am only seen the mobile URL in the desktop SERPS, other times I am seeing both the desktop and mobile URL for the same product. My understanding is that the mobile URL should not be ranking at all in desktop SERPS, could we be being penalised for either bad redirects or duplicate content? Any ideas as to how I could further diagnose and solve the problem if you do believe that it could be harming rankings?

Wordpress "incoming search terms" plugin
Hello everyone! newbie to SEO and have been trying to keep everything nice and ethical but I've seen on a couple of blogs today "incoming search terms" at the bottom of the blogs, then a bullet pointed list of search terms beneath it. So I had a quick search about the use of it and noticed wordpress has a plugin that automatic ally generates these "incoming search terms". I ask is this a legitimate plugin or will this harm my blog? I assume it generally will as I can't see this being much use for the audience, rather it would be 100% for trying to lure in search engines.

NoIndex/NoFollow pages showing up when doing a Google search using "Site:" parameter
We recently launched a beta version of our new website in a subdomain of our existing site. The existing site is www.fonts.com with the beta living at new.fonts.com. We do not want Google to crawl the new site until it's out of beta so we have added the following on all pages: However, one of our team members noticed that google is displaying results from new.fonts.com when doing an "site:new.fonts.com" search (see attached screenshot). Is it possible that Google is indexing the content despite the noindex, nofollow tags? We have double checked the syntax and it seems correct except the trailing "/". I know Google still crawls noindexed pages, however, the fact that they're showing up in search results using the site search syntax is unsettling. Any thoughts would be appreciated! DyWRP.png

Google.ca is showing our US site instead of our Canada Site
When our Canadian users who search on google.ca for our brand (e.g. Travelocity, Travelocity hotels, etc.), the first few results our from our US site (travelocity.com) rather than our Canadian site (travelocity.ca). In Google Webmaster Tools, we've adjusted the geotargeting settings to focus on the appropriate locale, but the wrong country TLD is still coming up at the top via google.ca. What's the best way to ensure our Canadian site comes up instead of the US site on google.ca? Thanks, Tory Smith

301 Redirect "wildcard" question
I have been looking at the SEOmoz redirect guide for some advice but I can't seem to find the answer : http://www.seomoz.org/learn-seo/redirection I have lots of URLs from a previous version of a site that look like the following: sitename.com/-c-25.html?sort=2d&page=1 sitename.com/-c-25.html?sort=3a&page=1 etc etc. I want to write a redirect so whenever a URL with the terms "-c-25.html" is requested it redirects to a specified page, regardless of what comes after the question mark. These URLs were created by our previous ecommerce software. The 'c' is for category, and each page of the cateogry created a different URL. I want to do these so I can rediect all of these URLs to the appropraite new cateogry page in a single redirect. Thanks for any help.
