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,

Schema markup for products is missing "price": Is this bad?
Hey guys, So a current client of mine has an e-commerce shop with a few hundred products. They purposely choose to keep the prices off of their website, which is causing errors in Google Webmaster Tools. Basically the error shows: Error: Structured Data > Product (markup: schema.org) Error type: missing price 208 items with error Is this a huge deal? Or are we allowed to have non-numerical prices for schema ie. "call for quote"

Does using data-href="" work more effectively than href="" rel="nofollow"?
I've been looking at some bigger enterprise sites and noticed some of them used HTML like this: <a <="" span="">data-href="http://www.otherodmain.com/" class="nofollow" rel="nofollow" target="_blank"></a> <a <="" span="">Instead of a regular href="" Does using data-href and some javascript help with shaping internal links, rather than just using a strict nofollow?</a>

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.

Meta tag "noindex,nofollow" by accident
Hi, 3 weeks ago I wanted to release a new website (made in WordPress), so I neatly created 301 redirects for all files and folders of my old html website and transferred the WordPress site into the index folder. Job well done I thought, but after a few days, my site suddenly disappeared from google. I read in other Q&A's that this could happen so I waited a little longer till I finally saw today that there was a meta robots added on every page with "noindex, nofollow". For some reason, the WordPress setting "I want to forbid search engines, but allow normal visitors to my website" was selected, although I never even opened that section called "Privacy". So my question is, will this have a negative impact on my pagerank afterwards? Thanks, Sven

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
