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.

Will content inside an "accordion" module be ranked as non-hidden content? Is there an official guide by google and other search engines addressing this?

SEO advice on ecommerce url structure where categories contain "/c/"
Hi! We use Hybris as plattform and I would like input on which url to choose. We must keep "/c/" before the actual category. c stands for category. I.e. this current url format will be shortened and cleaned:
Technical SEO | | hampgunn
https://www.granngarden.se/Sortiment/Husdjur/Hund/Hundfoder-%26-Hundmat/c/hundfoder To either: a.
https://www.granngarden.se/husdjur/hund/hundfoder/c/hundfoder b.
https://www.granngarden.se/husdjur/hund/c/hundfoder (hundfoder means dogfood) The question is whether we should keep the duplicated category name (hundfoder) before the "/c/" or not. Will there be SEO disadvantages by removing the duplicate "hundfoder" before the "/c/"? I prefer the shorter version ofc, but do not want to jeopardize any SEO rankings or send confusing signals to search engines or customers due to the "/c/" breaking up the url breadcrumb. What do you guys say and prefer from the above alternatives? Thanks /Hampus0 -

Magento Dublicate Content (Noindex and Rel"canonical")
Hi All, Just looking for some advice regarding my website on magento. We by mistake didnt enable canonical tags and noindex tags so had a big problem with dublicate content from filter pages but also have URLs to Cats as Yes so this didnt help with not having canonical tags enabled. We now have everything enabled for a few weeks now but dont see much drop in indexed pages in google. (currently 27k and we have only 5k products) My question basically is how do we speed up noindexation of dublicate content and also would you change URL to cats as No so google just now sees the url to products? (my concerns with this is would leaving it to Yes help because it will hopefully read the canonical tags on products now) Thank you in advance Michael

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>

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?

"Fourth-level" subdomains. Any negative impact compared with regular "third-level" subdomains?
Hey moz New client has a site that uses: subdomains ("third-level" stuff like location.business.com) and; "fourth-level" subdomains (location.parent.business.com) Are these fourth-level addresses at risk of being treated differently than the other subdomains? Screaming Frog, for example, doesn't return these fourth-level addresses when doing a crawl for business.com except in the External tab. But maybe I'm just configuring the crawls incorrectly. These addresses rank, but I'm worried that we're losing some link juice along the way. Any thoughts would be appreciated!

"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?
