We are looking at changing our URL structure for tracking various affiliates from:

https://sub.domain.com/quote/?affiliate_id=xxx

to https://aff_xxx_affname.domain.com/quote/

Both would allow us to track affiliates, but the second would allow us to use cookies to track. Does anyone know if this could possibly cause SEO concerns?

Also, For the site we want to rank for, we will use a reverse proxy to change the URL from https://aff_xxx.maindomain.com/quote/ to https://www.maindomain.com/quote/

would that cause any SEO issues.

Thank you.

Hello Rox,

I hate the idea of you going away unsatisfied with unanswered questions. Let's try to work through this. Let me approach it from a different way, as I may have misunderstood what you were asking.

https://sub.domain.com/quote/?affiliate_id=xxx

https://aff_xxx_affname.domain.com/quote/

The first URL is the one I'd go with because it's easy to rel canonical back to the base URL and you're keeping it all on one subdomain. The second version creates a new subdomain for every affiliate, which I don't think would be a good thing.

Please let me know if I have understood your question this time.

Thanks!

I don't feel this question is understood and I'm not sure how to explain it any further so I would like to close it, without marking any answers good or bad. I'm not sure how I would close it so am posting this response. Thank you.

Not if that something has to do with affiliate landing pages.

Isn't it good to let google see that our site does something as opposed to just being a glorified blog?

All of those subdomains should have a robots.txt file that disallows the search engine from accessing them in the first place. In that sense, it doesn't matter which you choose for SEO. Or am I missing something?

The sub-domain would not be redirected. It would be forwarded on to an application server to parse the sub-domains and continue with displaying a page customized for that affiliate (HTML, CSS, and verbiage all can change).

As for why the URL structure won't work, the site must throw an error if no affiliate ID is specified. It cannot simply assume the one in the cookie is correct.

Hi there.

So, are those affiliates domains gonna actually exist and be empty and be redirected from with proxy or it's gonna be simple htaccess rewrite rule?

In first case i can see lots of trouble with UX (do you like when after clicking on a link it takes you to a page, which refreshes several times before giving you end page result? - feels very spammy and unsettling, doesn't it?!)

In second case - there won't be any problems.

P.S. Why parameter URL structure doesn't let you use cookies? You can assign specific cookie based on parameter with simple php get. Or am i missing something?

What is the Redirect Rule for corresponding https urls to new domain with the same https urls?

2 sites have the same urls but the owner wants just the 1 site. So I will be doing a 301 redirect with .htaccess from https://www.example.co.uk/sportsbook/SOCCER/today/ redirecting to https://www.example.com//sportsbook/SOCCER/today/ There are a lot of urls that are the same, so I was wondering what the rule is to put in the file please that will change them all to the corresponding urls? Would this be correct?... RewriteEngine on
RewriteCond %{HTTPS_HOST} ^example.co.uk [NC,OR]
RewriteCond %{HTTPS_HOST} ^www.example.co.uk [NC]
RewriteRule ^(.*)$ https://example.com$1 [L,R=301,NC] Or would a simple rule like this work... redirect 301 / http://www.new domain.com/ If not correct could you please give me the correct rule, thanks! Then of course doing a change of address of address in webmaster tools after. Also... do I still need to do the forwarding from the https://www.example.co.uk/ domain provider after as well? Many thanks for your help in advance.

How much does URLs with CAPS and URLs with non-CAPS existing on an IIS site matter nowadays?

I work on a couple ecommerce sites that are on IIS. Both sites have return a 200 header status for the CAPS and non CAPS version of the URLs. While I suppose it would be ok if the canonicals pointed to the same version of the page, in some cases it doesn't (ie; /Home-Office canonicalizes to itself and /home-office canonicalizes to itself). I came across this article (http://www.searchdiscovery.com/blog/case-sensitive-urls-and-seo-case-matters/) that is a few years old and I'm wondering how much of an issue it is and how I would determine if it is/isn't?

Is it best to have products and reviews on the same URL?

Hi Moz, Is it better to have products and reviews on the same or different URLs? I suspect that combining these into one page will help with rankings overall even though some ranking for product review terms may suffer. This is for a hair products company with tens of thousands if not hundreds of thousands of reviews. Thanks for reading!

Complex URL Migration

Hi There, I have three separate questions which are all related. Some brief back ground. My client has an adventure tourism company that takes predominantly North American customers on adventure tours to three separate destinations: New Zealand, South America and the Himalayas. They previously had these sites on their own URL's. These URL's had the destination in the URL (eg: sitenewzealand.com). 2 of the three URL's had good age and lots of incoming links. This time last year a new web company was bought in and convinced them to pull all three sites onto a single domain and to put the sites under sub folders (eg: site.com/new-zealand). The built a brand new site for them on a Joomla platform. Unfortunately the new sites have not performed and halved the previous call to action rates. Organic traffic was not adversely affected with this change, however it hasn't grown either. I have been overhauling these new sites with a project team and we have managed to keep the new design but make usability/marketing changes that have the conversion rate nearly back to where it originally was and we have managed to keep the new design (and the CMS) in place. We have recently made programmatic changes to the joomla system to push the separate destination sites back onto their original URL's. My first question is around whether technically this was a good idea. Question 1 Does our logic below add up or is it flawed logic? The reasons we decided to migrate the sites back onto their old URL's were: We have assumed that with the majority of searches containing the actual destination (eg: "New Zealand") that all other things being equal it is likely to attract a higher click through rate on the domain www.sitenewzealand.com than for www.site.com/new-zealand. Having the "newzealand" in the actual URL would provide a rankings boost for target keyword phrases containing "new zealand" in them. We also wanted to create the consumer perception that we are specialists in each of the destinations which we service rather than having a single site which positions us as a "multi-destination" global travel company. Two of the old sites had solid incoming links and there has been very little new links acquired for the domain used for the past 12 months. It was also assumed that with the sites on their own domains that the theme for each site would be completely destination specific rather than having the single site with multiple destinations on it diluting this destination theme relevance. It is assumed that this would also help us to rank better for the destination specific search phrases (which account for 95% of all target keyword phrases). The downsides of this approach were that we were splitting out content onto three sites instead of one with a presumed associated drop in authority overall. The other major one was the actual disruption that a relatively complex domain migration could cause. Opinions on the logic we adopted for deciding to split these domains out would be highly appreciated. Question 2 We migrated the folder based destination specific sites back onto their old domains at the start of March. We were careful to thoroughly prepare the htaccess file to ensure we covered off all the new redirects needed and to directly redirect the old redirects to the new pages. The structure of each site and the content remained the same across the destination specific folders (eg: site.com/new-zealand/hiking became sitenewzealand.com/hiking). To achieve this splitting out of sites and the ability to keep the single instance of Joomla we wrote custom code to dynamically rewrite the URL's. This worked as designed. Unfortunately however, Joomla had a component which was dynamically creating the google site maps and as this had not had any code changes it got all confused and started feeding up a heap of URL's which never previously existed. This resulted in each site having 1000 - 2000 404's. It took us three weeks to work this out and to put a fix into place. This has now been done and we are down to zero 404's for each site in GWT and we have proper google site maps submitted (all done 3 days ago). In the meantime our organic rankings and traffic began to decline after around 5 days (after the migration) and after 10 days had dropped down to around 300 daily visitors from around 700 daily visitors. It has remained at that level for the past 2 weeks with no sign of any recovery. Now that we have fixed the 404's and have accurate site maps into google, how long do you think it will take to start to see an upwards trend again and how long it is likely to take to get to similar levels of organic traffic compared to pre-migration levels? (if at all). Question 3 The owner of the company is understandably nervous about the overall situation. He is wishing right now that we had never made the migration. If we decided to roll back to what we previously had are we likely to cause further recovery delays and would it come back to what we previously had in a reasonably quick time frame? A huge thanks to everyone for reading what is quite a technical and lengthy post and a big thank you in advance for any answers. Kind Regards

Indexed non existent pages, problem appeared after we 301d the url/index to the url.

I recently read that if a site has 2 pages that are live such as: http://www.url.com/index and http://www.url.com/ will come up as duplicate if they are both live... I read that it's best to 301 redirect the http://www.url.com/index and http://www.url.com/. I read that this helps avoid duplicate content and keep all the link juice on one page. We did the 301 for one of our clients and we got about 20,000 errors that did not exist. The errors are of pages that are indexed but do not exist on the server. We are assuming that these indexed (nonexistent) pages are somehow linked to the http://www.url.com/index The links are showing 200 OK. We took off the 301 redirect from the http://www.url.com/index page however now we still have 2 exaact pages, www.url.com/index and http://www.url.com/. What is the best way to solve this issue?

Search Refinement URLs

My site is using search refinement and I am concerned about the URL adding additional characters when it's refined. My current URL is: http://www.autopartscheaper.com/Air-Conditioning-Heater-Parts-s/10280.htm and when someone chooses their specific year, make, and model then it changes to: http://www.autopartscheaper.com/Air-Conditioning-Heater-Parts-s/10280.htm?searching=Y&Cat=10280&RefineBy_7371=7708. Will this negatively affect SEO for this URL? Will the URL be counted twice? Any help would be great!

Use of subdomains, subdirectories or both?

Hello, i would like your advice on a dilemma i am facing. I am working a new project that is going to release soon, thats a network of users with personal profiles seperated in categories for example lets say the categories are colors. So let say i am a member and i belong in red color categorie and i got a page where i update my personal information/cv/resume as well as a personal blog thats on that page. So the main site is giving the option to user to search for members by the criteria of color. My first idea is that all users should own a subdomain (and this is how its developed so far) thats easy to use and since the domain name is really small (just 3 letters) i believe subdomain worth since personal site will be easy to remember. My dilemma is should all users own a subdomain, a subdirectory or both and if both witch one should be the canonical? Since it said that search engines treat subdomains as different stand-alone sites, whats best for the main site? to show multiple search results with profiles in subdomains or subdirectories? What if i use both? meaning in search results i use search directory url for each profile while same time each profile owns a subdomains as well? and if so which one should be the canonical? Thanks in advance, C

URL Shorteners. Are they SEO Friendly?

Do URL shortener services like bit.ly act as 301 redirects? I was thinking about utilizing one for longer query based URLs and didn't want to risk losing link juice. Thanks for the insight! Regards - Kyle
