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 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

Using the word "FREE" in domain name
Hi, This may seem like a simple question but a new client of mine wishes to use a domain name with the word "free" in it. The website will offer free activity vouchers. I couldn't see this being a problem as there a lot of websites that do this although he was told it may present a problem with the search engines thinking the site was spammy. It won't be and will be offering information and vouchers on local sporting activities. I was wondering if anybody could clarify this please so I can give him a more definitive answer to his question. Thanks for your help.

"nofollow pages" or "duplicate content"?
We have a huge site with lots of geographical-pages in this structure: domain.com/country/resort/hotel domain.com/country/resort/hotel/facts domain.com/country/resort/hotel/images domain.com/country/resort/hotel/excursions domain.com/country/resort/hotel/maps domain.com/country/resort/hotel/car-rental Problem is that the text on ie. /excursions is often exactly the same on .../alcudia/hotel-sea-club/excursion and .../alcudia/hotel-beach-club/excursion The two hotels offer the same excursions, and the intro text on the pages are the exact same throughout the entire site. This is also a problem on the /images and /car-rental pages. I think in most cases the only difference on these pages is the Title, description and H1. These pages do not attract a lot of visits through search-engines. But to avoid them being flagged as duplicate content (we have more than 4000 of these pages - /excursions, /maps, /car-rental, /images), do i add a nofollow-tag to these, do i block them in robots.txt or should i just leave them and live with them being flagged as duplicate content? Im waiting for our web-team to add a function to insert a geographical-name in the text, so i could add ie #HOTELNAME# in the text and thereby avoiding the duplicate text. Right now we have intros like: When you visit the hotel ... instead of: When you visit Alcudia Sea Club But untill the web-team has fixed these GEO-tags, what should i do? What would you do and why?

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

How valuable is content "hidden" behind a JavaScript dropdown really?
I've come across a method implemented by some SEO agencies to fill up pages with somehow relevant text and hide it behind a javascript dropdown. Does Google fall for such cheap tricks? You can see this method used on these pages for example (just scroll down to the bottom) - it's all in German, but you get the idea I guess: http://www.insider-boersenbrief.de/ http://www.deko-und-kerzenshop.de/ How is you experience with this way of adding content to a site? Do you think it is valuable or will it get penalised?

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

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.
