How cloudflare might affect "rank juice" on numerous domains due to limited IP range?
-
We have implemented quite a few large websites onto cloudflare and have been very happy with our results. Since this has been successful so far, we have been considering putting some other companies on CL as well, but have some concerns due to the structure of their business and related websites.
The companies run multiple networks of technology, review, news, and informational websites. All have good content (Almost all unique to each website) and rankings currently, but if implemented to cloudflare, would be sharing DNS and most likely IP's with eachother. Raising a concern of google reducing their link juice because it would be detected as if it was coming from the same server, such as people used to do for their blog farms.
For example, they might be tasked to write an article on XYZ company's new product. A unique article would be generated for 5-10 websites, all with unique, informative, valid and relevant content to each domain; Including links, be it direct or contextual, to the XYZ product or website URL. To clarify, so there is no confusion...each article is relevant to its website...
technology website- artciel about the engineering of xyz product
business website - How xyz product is affecting the market or stock price
howto website - How the xyz product is properly usedCurrently all sites are on different IP's and servers due to their size, but if routed through cloudflare, will Google simply detect this as duplicate linking efforts or some type of "black hat" effort since its coming from cloudflare?
If yes, is there a way to prevent this while still using CL?
If no, why and how is this different than someone doing this to trick google?Thank you in advance! I look forward to some informative answers.

Thank you for some great information! I am reading it over now!
The concern is not necessarily the page rank or da of the actual sites with the content linking to the other site, but that google might reduce or diminish the link juice of the actual links since they would likely detected as originating from the same server.
It might be 5-10 websites, original content...but not really something we can "test and see"
Thank you again!

For a small number of sites I would not be concerned, but if you are worried, Try Microsoft Azure you get a unique ip for each website and they are very cheap with a great interface.

Where did you get that information for all sites being on different IP's? I ask because 3 of the sites we are using for some clients all are coming from the same IP or the same c block or range.
A better question might be if there is a way to ensure they are served from different IP's since we cannot risk it.
Side note, I am waiting for a response from CL as well and will post their info if relevant.
thanks!

UPDATED/CLARIFICATION: Responding to your comment "Currently all sites are on different IP's and servers due to their size."
Your server IP addresses (A Records) will stay unique/same. The IP is masked by Cloudflare's Anycast using different IP addresses across the world, depending where used can be identical or in similar range. They cache static content with a short expiry time; for non-cached content their servers proxy through requests to the actual server then forward to a user.
See http://www.quora.com/CloudFlare/How-does-CloudFlare-work for a detailed response from CloudFlare's CEO to a similar question.
Now Google "should" first of all understand how Cloudflare works as a CDN just like it does with other similar CDNs and security platforms.
Does Google care about same IPs no, unless there are spammy neighbors using it:
“… there was recently a discussion on a NANOG (North American Network Operators Group) email list about virtual hosting vs. dedicated IP addresses. They were commenting on the misconception that having multiple sites hosted on the same IP address will in some way affect the PageRanks of those sites. There is no PageRank difference whatsoever between these two cases (virtual hosting vs. a dedicated IP).” Cutts Blog
Should Google figure this out and be able to differentiate the Cloudflare masking yes. But has Google been found with incorrectly diagnosing spam yes, with probably less complex issues to Cloudflare. The question may be do you want to take the risk, or partial risk as you can actually use your own DNS and cloudflare (paid version) again hoping assuming Google will understand.
Hope this helps, curious as to how Cloudflare will respond to this, so please update. But as an SEO'r it would depend how much risk you want to take in this case.

What are legit ways to raise up you're ranking for a new website?
I have a wallpaper website that i just made and bought a template that looks fine for the site so far for a month now, and i wanted to know what steps i cant take to better rank my site and build some traffic along the way. I use only specific directories, not sure how to get a press release done and also link back to other sites from pages that get a decent amount of traffic where i can leave a link to it, of course not leaving any type of spammy looking comments. This is the site i am working on right now, freehdwallpapers.be I have linked back from a few sites already, i look at the alexa rank if it will show a number at one point, the sites worth is still pretty low, and also i have added social networks on the site which has gained a number of followers to this day, so i got work to do still. I just don't want to go on about it the wrong way and get penalized by google.

Please Please Please help (not ranking any more)..
my website is: www.tcclinic.com it was a static website which was ranking well. total about 400 pages. I also had my blog hosted on another domain (www.shopify.com) about 800 pages. I was told if I bring the blog to my domain, then I will have more content on my site and will rank even better, and also was advised to switch to WordPress. so about two weeks ago I did the following changes: I moved the site and blogs to my domain (tcclinic.com). and switch to WordPress. total of 1200 pages Since it was changing to WordPress all the URLs was changed and named differently. I did 301 redirect for all the pages. all the URLs now contains "toronto-cosmetic-clinic" which is the name of my clinic example: www.tcclinic.com/toronto-cosmetic-clinic-liposuction-surgery/ www.tcclinic.com/toronto-cosmetic-clinic-tummy-tuck/ most of my pages are indexed by google now BUT Now as the result I am not ranking anywhere in first 5 to 6 pages. I am not sure what is happening. have I been hit by a penguin, panda or any other black and white animal ? if this is the case how do I know this happened. Haveing "toronto-cosmetic-clinic" in all the URLs is considered as keyword stuffing ? moving 800 pages of blog to my domain caused it ? (blogs are removed from shopify.com) Is it just the matter of time to come back to the first page? Please let me know what you think.... Thank you

Spammy Links (from .ru) pointing to my domain! How to deal with it?
Hi all, We run an e-commerce store - I am just looking at the apache logs and I am finding a lot of spammy links that have been referrers to our pages - when I check the links, I cannot find our URL in an HREF on their page so I presume they may be using some country based cloaking? These are the domains that are targeting specific pages on our site:

It Shows as "google results" but it's an incoming links, is it spaming me...?
Hello everyone I have 2 issues to share: 1) We have a site (personal-loans.org), In the past few weeks we notice that there are sites that have links to our site and we get traffic from them but...! when you go online to these sites they show you that all they do is provide "google search" results, because we where in first page on the results we had hits there as well what leads me to think that this is the reason we are at page 7 now after yesterday the ranking was at page 4. these are some of these sites so you can see it: internetpayadvances.com fastlivecashadvance.com assistancemoney.com scoutcashnow.com officialpayday.net Does anyone else got to see anything like that...??? I have many more links like that, these are only 5 out of 9 that had hits yesterday only, site traffic went from 250-300 to 63 a day... For the same site - it was on google search results 1st page and ranked 4-7, even after the big penguin changes. What we did notice is that A LOT of non related sites like surfing (yes ocean surfing) and sites that had no content AT ALL - all the text was inside of an image and ranked 3! 3rd on payday loans search result. (and the rest was and still just looks the same with different content...) Google say they want quality but does not do homework for the 2nd largest search for keywords such as loans and payday loans market, same goes for the cash advance. Please help, need your advice.... Thanks

Geotargeting a new domain without impacting traffic to existing domain
I had previously asked this as a 'private question' and couldn't make it a 'public question' automatically-- hence reposting it as a new question: We have an existing site, let's say www.xyz.com --- which attracts traffic from all over the world (including the US), though it's primary audience is the UK/ Europe. Most of this traffic is via organic search results on Google. Now, there is a business case to launch a US-centric website -- www.xyz.us, which will have most of its content from the original site (probably with some localization). Our goal is that on day 1 when the new site xyz.us is launched, we want all traffic originating from the US (and may be some other North American countries) to be directed to the .us domain instead of the .com domain. We don't want to lose any search engine traffic; equally importantly, we want this to be done in a manner that is seen by the search engines as a legitimate technique. What are the best options to do this such that the new .US site automatically inherits all of the traffic from the .com site on day 1, without either of these sites getting penalized in any form. Thanks.

Can you block backlinks from another domain
Wondering if this is somehow possible. A site got hacked and created a /data folder with hundreds of .php files that are web pages selling all sorts of stuff. We deleted the /data folder and blocked Google from indexing it. Just noticed in Webmaster Tools that the site has 35,000 backlinks from other sites that got hacked with the same way. Is there a way to block these sites? I am assuming there isn't, but wanted to see if anyone ran into the same problem. It is a wordpress site is that helps.
