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.

Does anyone know the linking of hashtags on Wix sites does it negatively or postively impact SEO. It is coming up as an error in site crawls 'Pages with 404 errors' Anyone got any experience please?
Does anyone know the linking of hashtags on Wix sites does it negatively or positively impact SEO. It is coming up as an error in site crawls 'Pages with 404 errors' Anyone got any experience please? For example at the bottom of this blog post https://www.poppyandperle.com/post/face-painting-a-global-language the hashtags are linked, but they don't go to a page, they go to search results of all other blogs using that hashtag. Seems a bit of a strange approach to me.

Google Search Console "Text too small to read" Errors
What are the guidelines / best practices for clearing these errors? Google has some pretty vague documentation on how to handle this sort of error. User behavior metrics in GA are pretty much in line with desktop usage and don't show anything concerning Any input is appreciated! Thanks m3F3uOI

Sudden Indexation of "Index of /wp-content/uploads/"
Hi all, I have suddenly noticed a massive jump in indexed pages. After performing a "site:" search, it was revealed that the sudden jump was due to the indexation of many pages beginning with the serp title "Index of /wp-content/uploads/" for many uploaded pieces of content & plugins. This has appeared approximately one month after switching to https. I have also noticed a decline in Bing rankings. Does anyone know what is causing/how to fix this? To be clear, these pages are **not **normal /wp-content/uploads/ but rather "index of" pages, being included in Google. Thank you.

Does an Apostrophe affect searches?
Does Google differentiate between keyphrase structures such as Mens Sunglasses & Men**'**s Sunglasses? I.e. does the inclusion/exclusion of an apostrophe make any difference when optimising your main keyword/phrase for a page? Keyword explorer appears to give different results..... I.e. no data for Men's Sunglasses, but data appears for Mens sunglasses. So if I optimise my page to include the apostrophe, will it screw the potential success for that page? Thanks 🙂 Bob

"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

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?
