Privacy: Is Whois info used to help establish an admin relationship between sites in addition to host/IP etc ?
-
Hi
Do you think Google looks at WhoIs details as a contributing factor to establishing an adminsitrative relationship between two domains (in addition to being hosted on similar hosts/IP blocks etc), and in regard to linkbuilding would having teh same whois details on both sites have a negative effect or be perfectly ok (if the sites are on different hosts/ip blocks) ?
Also do you think whois privacy turned on has a negative effect on trust and subsequent seo ?
Considering the answer to the above two questions: Do you think its a good or bad idea to have domain reg/whois ‘privacy’ turned on for a site of curated content relating to the project/primary sites niche, and linking to this site for contextual link benefit ?
Im building out a site of curated content that i want to perform well in-itself as well as providing backlink benefit to the primary site but worried if they both have same whois details will cause seo problems or would that only be if also had same host/ip footprint ?
Should i enable whois privacy, use a different address for reg, or actually make a point of using the same whois details for transparency ?

cool cheers

I would personally, but not for any SEO benefits or trying to hide anything to Google. Just because I can and stops people snooping.

Hi there
I really don't think it matters overall in the grand scheme so long as you are providing a valuable experience with your content and take proper steps to eliminate duplicate content issues.
To reference Andy below, there are sites that get tons of organic rankings / traffic with private Whois sites, and the same for public Whois. In the grand scheme of thinks, if you are linking naturally and not abusing anchor text and giving credit where it is due, you should be fine.
Hope this helps!

So IYO prob is best if i turn privacy on rather than 'potentially' show an administrative relationship by having same details ?
-
great thanks Andy !
-
Thanks Patrick !
So having whois data same for two interlinking sites could negate or heavily reduce any link benefit since they do likely use it to determine administrative relationship ? so should turn privacy on except that can also reduce trust in the domain!
So any ideas which is the least worse option if that is the case ? reducing the trust via privacy on option or admitting an admin relationship between the sites via whois option ?
All Best

So your saying that if i use 'who is privacy on' for the new site, it shouldn't have a negative effect for that sites seo
Absolutely. I have a wide range of clients, some of who like to hide their personal details and others who don't. None have any negative effects for either. Google is more interested in how good a site is, rather than who the admin contact is.
Can I just add, if there is actual test data that I haven't seen, I would be very interested to have a look.

Definitely true! I was just stating it for the reference of Matt talking about Whois data back then to reference information.
-
Just be a little cautions with info dating back to 2006-2007. You can't rely on that now.
-
Thanks for the quick response Andy !
So your saying that if i use 'who is privacy on' for the new site, it shouldn't have a negative effect for that sites seo BUT Google doesn't look at 'WhoIs' info to establish an administrative relationship between two sites anyway, hence there's no need to use it since same whois details shouldn't cause any issues?

Hi there
Cyrus gave a great answer to this a few years back. You can read that here.
That being said, some people think Whois data is used as a ranking factor (6, 8, 9, 63) or at least used in some ranking factors.
Matt Cutts has stated as well:
"…When I checked the whois on them, they all had “whois privacy protection service” on them. That’s relatively unusual. …Having whois privacy turned on isn’t automatically bad, but once you get several of these factors all together, you’re often talking about a very different type of webmaster than the fellow who just has a single site or so."
In my opinion, it's better to be open than hide information. But that's upto you to do the research and see what best suits you.
Hope this helps! Good luck!

I would say this is a resounding no to both questions here Dan. I have never seen anything that would suggest this and can imagine it would be full of problems for Google to try and do.
Use WHOIS privacy if you don't want anyone to see who the site belongs to, but that is as far as your concerns need go

Best Web-site Structure/ SEO Strategy for an online travel agency?
Dear Experts! I need your help with pointing me in the right direction. So far I have found scattered tips around the Internet but it's hard to make a full picture with all these bits and pieces of information without a professional advice. My primary goal is to understand how I should build my online travel agency web-site’s (https://qualistay.com) structure, so that I target my keywords on correct pages and do not create a duplicate content. In my particular case I have very similar properties in similar locations in Tenerife. Many of them are located in the same villa or apartment complex, thus, it is very hard to come up with the unique description for each of them. Not speaking of amenities and pricing blocks, which are standard and almost identical (I don’t know if Google sees it as a duplicate content). From what I have read so far, it’s better to target archive pages rather than every single property. At the moment my archive pages are: all properties (includes all property types and locations), a page for each location (includes all property types). Does it make sense adding archive pages by property type in addition OR in stead of the location ones if I, for instance, target separate keywords like 'villas costa adeje' and 'apartments costa adeje'? At the moment, the title of the respective archive page "Properties to rent in costa adeje: villas, apartments" in principle targets both keywords... Does using the same keyword in a single property listing cannibalize archive page ranking it is linking back to? Or not, unless Google specifically identifies this as a duplicate content, which one can see in Google Search Console under HTML Improvements and/or archive page has more incoming links than a single property? If targeting only archive pages, how should I optimize them in such a way that they stay user-friendly. I have created (though, not yet fully optimized) descriptions for each archive page just below the main header. But I have them partially hidden (collapsible) using a JS in order to keep visitors’ focus on the properties. I know that Google does not rank hidden content high, at least at the moment, but since there is a new algorithm Mobile First coming up in the near future, they promise not to punish mobile sites for a collapsible content and will use mobile version to rate desktop one. Does this mean I should not worry about hidden content anymore or should I move the descirption to the bottom of the page and make it fully visible? Your feedback will be highly appreciated! Thank you! Dmitry

Help changing category and page titles on established Magento site.
Hi All, This is my first post, I've been a Pro member for a while now, read many posts but have never asked a question here. I have an established Magento site that I need to do a lot of SEO work on. I am a newbie at SEO, so I wanted to ask for advice here. I just changed one of the category names, the url, meta title, and meta description. When making the change I selected the checkbox in the Magento backend that says "Create Permanent Redirect for Old URL" Example:
Technical SEO | | TrulyLuna
Old Category: http://www.domain.com/old-category-name.html
New Category: http://www.domain.com/new-category-name.html Everything worked fine with the exception of one alarming thing... I lost all of the page authority for the category itself and all of the sub categories and pages below it. Now the category and all pages below it show (on the moz toolbar) a PA of 1 and 0 links and 0 domains. I updated the sitemap. I did not do a 301 redirect in the .htaccess, I only chose the option to redirect on the Magento backend when changing the name and url of the category. I need to change a lot of other category and page names and urls but now I'm a bit gun shy, as I do not want to do something that will damage what little page rank I have at the moment. I'm looking for some advice from one of you guys who might be able to help me do this the correct way. I did some research on Google, but I'm still not sure of the correct method to accomplish this. Thanks in advance for any help that you can offer.0 -
Switching Site to a Domain Name that's in Use
I'm comfortable with the steps of moving a site to a new domain name as recommended by Google. However, in this case, the domain name I'm asked to move to is not really "new" ... meaning it's currently hosting a website and has been for a long time. So my question is, do I do this in steps and take the old website down first in order to "free up" the domain name in they eyes of search engines to avoid large numbers of 404s and then (in step 2) switch to the "new" domain in a few months? Thanks.

Redesign existing websites / worried about urls / mapping
Hi Guys, While redesigning existing websites that will have page name changes such as: example.com/products to be called example.com/solutions example.com/about-us to be called example.com/about should I 301 the old url to the new url. In the past I have not done this & I'm just wondering from an SEO point of view how bad is this? (On a scale of 1 to 10 how bad is this not 301ing urls, 10 being really bad & 1 being fine), Thanks.
