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,

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?

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?

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/

Hyphenated Domain Names - "Spammy" or Not?
Some say hyphenated domain names are "spammy". I have also noticed that Moz's On Page Keyword Tool does NOT recognize keywords in a non-hyphenated domain name. So one would assume neither do the bots. I noticed obviously misleading words like car in carnival or spa in space or spatula, etc embedded in domain names and pondered the effect. I took it a step further with non-hyphenated domain names. I experimented by selecting totally random three or four letter blocks - Example: randomfactgenerator.net - rand omf act gene rator Each one of those clips returns copious results AND the On-Page Report Card does not credit the domain name as containing "random facts" as keywords**,** whereas www.business-sales-sarasota.com does get credit for "business sales sarasota" in the URL. This seems an obvious situation - unhyphenated domains can scramble the keywords and confuse the bots, as they search all possible combinations. YES - I know the content should carry it but - I do not believe domain names are irrelevant, as many say. I don't believe that hyphenated domain names are not more efficient than non hyphenated ones - as long as you don't overdo it. I have also seen where a weak site in an easy market will quickly top the list because the hyphenated domain name matches the search term - I have done it (in my pre Seo Moz days) with ft-myers-auto-air.com. I built the site in a couple of days and in a couple weeks it was on page one. Any thoughts on this?

Delete old site but redirect domain to a new domain and site
I just have a quick query and I have a feeling about what the answer is so just wanted to see what you guys thought... Basically I am working on a client site. This client has a few other websites that are divisions of their company. However these divisions/websites are no longer used. They are wanting to delete the websites but redirect the domains to their name main website. They believe this will pass on SEO benefits as these old division sites are old and have a good PR and history. I'm unsure for DEFINITE, which way is correct?

Index forum sites
Hi Moz Team, somehow the last question i raised a few days ago not only wasnt answered up until now, it was also completely deleted and the credit was not "refunded" - obviously there was some data loss involved with your restructuring. Can you check whether you still find the last question and answer it quickly? I need the answer 🙂 Here is one more question: I bought a website that has a huge forum, loads of pages with user generated content. Overall around 500.000 Threads with 9 Million comments. The complete forum is noindex/nofollow when i bought the site, now i am thinking about what is the best way to unleash the potential. The current system is vBulletin 3.6.10. a) Shall i first do an update of vbulletin to version 4 and use the vSEO tool to make the URLs clean, more user and search engine friendly before i switch to index/follow? b) would you recommend to have the forum in the folder structure or on a subdomain? As far as i know subdomain does take lesser strenght from the TLD, however, it is safer because the subdomain is seen as a separate entity from the regular TLD. Having it in he folder makes it easiert to pass strenght from the TLD to the forum, however, it puts my TLD at risk c) Would you release all forum sites at once or section by section? I think section by section looks rather unnatural not only to search engines but also to users, however, i am afraid of blasting more than a millionpages into the index at once. d) Would you index the first page of a threat or all pages of a threat? I fear duplicate content as the different pages of the threat contain different body content but the same Title and possibly the same h1. Looking forward to hear from you soon! Best Fabian
