How to flag inbound affiliate links to Search Engines
-
Afternoon Mozzers,
I was chatting to our VP of marketing earlier about one of our sites with a somewhat unhealthy looking link profile. This is primarily caused by the sector its in and the fact that lots of low quality lead generators / affiliates operate there, sending traffic to us in return for payment on accepted leads.
Now, he recalled that there is a way to mark these inbound links, through a URL parameter he thought, as being affiliates and therefore should be ignored as we don’t want them misinterpreted as an attempt to manipulate our rankings.
I have been doing a spot of research but can't find a straight answer. heres a few articles i looked at: blogaid, Yoast, Webmaster world and the Moz Q&A.The problem is all these are from the perspective of a site linking out and acting as an affiliate, so all deal with that page not losing PR. The two methods i have derived from this boil down to:
- No follow the links
- Use an intermediary redirect page and script which you can block from robots.txt
So, back to our case - Are there any ways we can signal to Search engines, as the destination site, that these links are from affiliates (such as this URL parameter our VP had vague recollections off) or should i just get in touch and ask the sites to make them Nofollow?
Thanks, Tom.

Tom,
You can use the Disavow Links tool to do this for existing links, though I would advise updating the way your affiliate program works so as to avoid the issue going forward. For example, when providing the link code to affiliates include the rel nofollow tag, as mentioned above.
Most affiliate programs will send the user through an internal redirect, which can pass on the unique identifying parameter for the affiliate so they get credit for the conversions. I understand you may not want to go that route due to the work involved, but this is really the standard for affiliate programs these days. It allows you complete control on your end without having to bother the affiliates to update their links.
Good luck!

Hi Bradley and thanks for the feedback.
I’m reluctant to use the intermediary page / redirect combo as our publishers also append URL parameters for use in internal tracking and commission payment to their landing pages. As we have a large number of these affiliates having to set up a series of redirect cases (which i know we could do by identifying their source and original URL values) could be more effort than its worth, particularly with on-going maintenance. As such I'm currently inclined to go with the nofollow approach.
It seems through the silence in the Moz community that there is no URL parameter either so I’m assuming our VP was alluding to the two methods discussed which is what i was hoping. Going to leave this question open a little longer however just in case anyone else has any further insights!
Thanks, Tom.

I think using an intermediary page with a redirect script is the way to go. This allows you to modify the redirect (301 vs 302), the server header, and the destination - after the fact.
Ideally, you could do this going forward. For your current affiliates, you could reach out to them and provide a new affiliate link, or ask them to nofollow the link. This part isn't ideal, but if you had the intermediary redirect page you could handle this without contacting the affiliate.

Can 302 chains (affiliate links) from "toxic" sources hurt you? Or are you "shielded"?
Hi, I'm going through some affiliate links, which send visitors to our website via a chain of several 302 redirects Some of them are relevant links, others perhaps not so much. I know that Google doesn't pass PageRank on 302s... But are they still considered valid links that pass, let's say, "reputation", "relevance", "link neighbourhood" kind of signals? Otherwise put, is a 302 similar to adding the "nofollow" attribute on a link? Sort of? Not at all? More succinctly put, should I be worried about "toxic" sources separated from us by 302 redirect chains? By the way, yes I recognize that (Google's 302 redirect chain handling aside) associating our brand with perhaps what some might consider spammy websites is not in general a good move; I'm concerned with the technical SEO implications here however. In fact, this technical information may very well help drive decisions/policies on where we allow our affiliate advertising to appear. Thanks 🙂 PS - The affiliate company by the way is cj.com if that helps

What impact do affiliate links have on SEO
We commonly reference engineering standards on our site (because half our products are known and searched for by those standard names) and have just signed up as an affiliate to an organisation that sell the standards. Which seems a nice match We're going through and making sure all are no follow now because that seems the general advice - but should we be doing anything else? Yoast says you should mask affiliate links - https://yoast.com/affiliate-links-and-seo/ - but that was from 2010. Matt Cutts is fairly clear on nonfollow - http://www.webpronews.com/heres-what-googles-matt-cutts-says-about-affiliate-links-and-nofollow-2012-06 - but not on whether it affects SERPS Does it? And what is the best way to handle it? This is a typical example of a page where we would have an affiliate link or two. http://www.oakleysteel.co.uk/fake-mill-certificates-en10168

Affiliate marketing dead?
I have created a network of travel websites that I have decided to promote little by little.. Also so they getdomain age and google trust.... but now when you search for all my main keyphrases... you either have wikitravel,lonelyplanet,frommers and other big brand. I guess that Google gave them better value as to get trusted travel information... However, it seems it will be very difficult to rank my sites. I could do long tail keyphrases but again might not be worth it... I used to work as a SEO consultant for other travel sites selling products... they still rank pretty well as they are sites of value selling something.. of course threy compete with other sites but we are in the same level. How can you compete with loneyplanet with your affiliate site because I am not selling anything on my sites. I am pretty much desperate. I designed a network of 30 sites... all good content with good SEO on the page... of course, I will be honest. I might have to change the content to make it better... you can check one of my site here; www.simplyparis.org it is worth it or better stop this project and focus on 1 product oriented website ? Is anyone working as an affiliate marketer with experience after google panda and pinguin ? is affiliate marketing dead in 2013 now?

Affiliate URLs Indexed in Google
We have an active in-house affiliate program which has a create-a-link function where affiliate, as in most affiliate programs, can build links back to our content to produce sales. The problem that I am seeing is that some of the affiliate URL versions are being indexed in Google rather than the original page. For instance.. http://www.ourdomain.com/page_start.aspx?affnum=F025212&Start_Page=RaceCar&referrer=createlink is outranking... http://www.ourdomain.com/racecar This presents 2 issues for us. First, this presents duplicate content issues obviously. Second, we pay our affiliates a portion of the sales so, in order to maximize profitability, we'd like the indexed pages to be the original version. What's the best way to handle this? I want to make sure that affiliates continue to get credit for links from their sites but search engine links should go to the original versions.

Promoting an Affiliate Scheme
I have to promote an affiliate scheme, and am drawing up a list of techniques that I can use to get people interested and sign up to it. Currently I have: Promoting the scheme in any article promotion. Identifying relevant websites to the scheme, and contacting them directly. Networking in affiliate forums and communities. Promoting on Facebook and Twitter. Possibly producing a video reviewing the scheme and posting it onto YouTube and other video sites. Can anyone think of any other techniques that I could try using? Cheers.

Link juice from my affiliates to my site
I'm setting up an affiliate program through 1shoppingcart. Even though I run 3 different websites, the way their program works is that I have to have 1 domain name that my affiliates get as their affiliate link, with their unique id attached at the end. I can give them multiple links that will redirect to various places on my 3 websites, but those original links that they put on their site will all be to just 1 domain. I'm wondering if I still get link juice to my sites even though the links are obviously being redirected? Does it depend on the redirection method? I was just thinking that getting hundreds of affiliates who run related sites could be a very good seo boost if they're all linking to my site, but I feel like it's going to be wasted because of this redirection thing. Hope this made sense. Thanks very much,
