Subdomains and duplicate content issue
-
Hi, a website I know of, let's call it Americanizedwine.com, is undergoing development. It includes a detailed map of hundreds wine growers right across the Americas, with all the map grower icons / names pointing to unique pages within Americanizedwine.com (info pages with online retail functionality where wine grower wants to sell direct through this website).
This website is teaming up with wine magazines / food blogs etc., offering them subdomains of Americanzedwine.com - e.g. [magazinename].americanizedwine.com - to carry within their own websites > duplicating the map and all the wine grower/retail pages from Americanwizedwine.com website, including meta data, etc (hmmmm!).
Could you simply use some method to simply tell Google that the mother website is elsewhere, and this subdomain information is simply duplicate copy? Would that suffice I’m wondering? Or will the solution here require deeper exploration?

Thanks Oleg and Matt for the really helpful feedback
-
What Oleg said - the pages should be no-index. They aren't for search engines, they're for the magazines. I wouldn't necessarily set canonical for all those pages because I'm not a fan of having 50 pages say their real link is something else. In your situation, just no-index anything that's for people, not SEs.

Hmm, you should either set a canonical url to the main site or noindex the other pages.
Since your main site already has all the information, the other subdomains won't rank for any terms anyways and you may be hit with duplicate content problems. Setting a canonical link will prevent the subdomains from ranking and any links built to that page will help your main site rank better. On the downside, the subdomains wont rank.

What is the danger of integrating different affiliate program widgets far under our core content?
We have pages with lots of unique content that are ranking very well in google.
Affiliate Marketing | | lcourse
I am now considering to add towards the end of the pages widgets from the booking.com affiliate program and also from the affiliate program of two other accommodtion sites. These affilliate widgets would be placed far beyond our core content in the bottom 15% of the page. Each widget will contain a large number of links to the different accomodation options that booking.com or others offer. In our context this information would be indeed very useful for our visitors. Shall I be concerned that our google rankings may suffer due to google perceiving our site as less quality (or google misinterpreting our intent to generate traffic to affiliate programs) ? If google rankings would be suffering, is this something we would normally see in a week (most of our pages are crawled daily by google) and then recover in a week when we would remove the widgets or would this generally be something that would affect the ranking over the course of a month or more? Shall I be concerned abou link dillution since my pages would now have a lot of links pointing to the affiliate sites, which could devalue my internal links? Any thoughts?0 -
What's the best way to go about making Duplicate Content Pages on my domain for affiliates?
Hello, I would like to make a bunch of duplicate pages of my site's Home Page, that way affiliates of mine can have a page of their own with links specialized to themselves littered throughout the page. What's the best practice going about this without jeopardizing domain authority from tons of duplicate content signals firing off?

Affiliate links and parameters creating duplicate page titles
Hi, we have an affiliate system and use rel=**canonical **to canonicalise them to the right link. Still, we see those links creating duplicate page titles, in Moz crawl and in Google search console. How are we supposed to treat those links so they do not create duplicate content? Thanks for your help!

Issues with centrally hosting your own affiliate links?
Can anyone see any issues centralising affiliate links across a network? Example - many of us would use some kind of redirect from our sites like abc.com/go/afflink1
Affiliate Marketing | | RaceMedia
bcd.com/go/afflink1 using either htaccess, php or javascript to redirect to the affiliate site But as your network of site grows - to change a link involves visiting 40 sites to change each of the files in the "go" folders. Would there be any net effect from using an otherwise vacant domain to host the links - so they only need to be changed in one place? Example
abc/go/afflink1 links to afflinks.com/1 which then redirects to affiliate site
bcd/go/afflink1 links to afflinks.com/1 which then redirects to affiliate site So all your links across the network for afflink1 would point to your afflinks.com/1 Any changes only require changes to one file afflinks.com/1 Assuming there is nothing else on afflinks.com - would there be any issues? Assume all links no followed and afflinks.com noindex. AND.... our redirects have been in place for some years using javascript,php or .htaccess. What is the current best practice for redirecting affiliate links?0 -

Affilate Programs on Subdomains
Hello SEO Community! We are launching an affiliate program and for CMS flexibility the preferred, development solution, is putting the affiliate program on a subdomain. Financial incentive affiliate programs "don't pass link value." Lets pretend they do for this situation 🙂 Here is the example: company website= example.com affilate website= affiliate.example.com Proposed affilate program: affilate.example.com/12345 -->301 redirects --> example.com There are multiple business services so sometimes the 301 redirect looks like this: affilate.example.com/23457 -->301 redirects ---> example.com/busines-service-foo affilate.example.com/23457 -->301 redirects ---> example.com/busines-service-bar note: The business services provided are very different. As a result, these links will be placed on very different types of website. To keep contextually relevant links in the 301 redirect should the affiliate look like this?: affilate.example.com/busines-service-foo/23457 -->301 redirects ---> example.com/busines-service-foo affilate.example.com/busines-service-bar/23457 -->301 redirects ---> example.com/busines-service-bar Thanks in advance for your feedback! If anyone can point me in the direction of an ideal way to set up affiliate programs that would be great. Especially regarding: canonical tag, # in url, 301 Any arguments about keeping the the affiliate off a subdomain are also very welcome. Thanks!

Duplicate versions of pages on my site are getting indexed by Google...I think...
Hello, Our site has a very high bounce rate, which in part is down to a slightly old fashioned design, and also because we are a retailer and I imagine many visitors are simply quickly comparing prices and then leaving. However, having had a look in Google Analytics, I think that there is another issue that is contributing to a very high bounce rate. When I look in Content > Top Content, and order the pages in order of Bounce Rate, high to low, there are hundreds of instances of pages with just one or two visits in the last month, and a 100% bounce rate. The links are the same as our home page or pages on our website, but with extra letters and numbers at the end of the url. We have an affiliate scheme, which provides our affiliates with unique codes for the products they want to link to, and my guess is that these urls are getting indexed. I've looked at a few other links, and they go to translated versions of a page from our website, generated by Google. Other urls seem to have been generated by search results from our own search on the website. What worries me is that there are lots and lots of versions of the same page, with slightly different urls. I am by no means an SEO expert - I work for a very small company and am basically learning as I go - but I know that duplicate content is bad news. If the pages were on our own site, we could use 301s to redirect, but what about translated versions, or urls generated by affiliate schemes, or search results? Many thanks, Sophy

Any issues with a simple php redirect?
Hi, I have used a simple php redirect for one site that it used for an affiliate link. Always used it, cant remember the exact reason I did but most likely to make the url pretty 🙂 On the crawl stats of this domain it shows as a 302 redirect - does this have any issues? What do people recommend for affiliate links? Cloaking? Tracking? There are a number of wordpress plugins available that seem to be aimed at affiliate links, any recommendations? I assume that they will still be classed as 302's. Any advice gratefully received. Thanks Jason
