E Commerce product page canonical and indexing + URL parameters
-
Hi,
I'm having some issues on the best way to handle site structure. The technical side of SEO isn't my strong point so I thought I'd ask the question before I make the decision.
Two examples for you to look at.
This is a new site http://www.tester.co.uk/electrical/multimeters/digital.
By selecting another page to see more products you get this url string where/p/2. This page also has the canonical tag relating to this page and not the original page.
Now if say for example I exclude this parameter (where) in webmaster tools will I be stopping Google indexing the products on the other pages where/p/2, 3, 4 etc. and the same if I make the canonical point to multimeters/digital/ instead of multimeters/digital/where/p/2 etc.?
I have the same question applied to the older site http://www.pat-services.co.uk/digital-multimeters-26.html. which no longer has an canonical tags at all.
The only real difference is Google is indexing http://www.pat-services.co.uk/digital-multimeters-26.html?page=2 but not http://www.tester.co.uk/electrical/multimeters/digital/where/p/2
Thanks for help in advance

If you're not experiencing any serious problems and just want to prevent future issues, I'd probably use rel=prev/next here:
http://googlewebmastercentral.blogspot.com/2011/09/pagination-with-relnext-and-relprev.html
It was designed specifically for paginated content and won't block your link-juice flow to deeper pages. Google has in the past said you can canonical to the "View All", but don't canonical back to page one. I've heard mixed results on the "View All" technique.
One thing, though - you currently have all these pages NOINDEX,FOLLOW'ed, so it's kind of a moot point. What you could do is just lift the NOINDEX on page 1 of results and keep it for pages 2+. That may be your least risky move at this point.

Canonicals don't prevent anyone from indexing the page. Canonicals let you select which duplicate pages show up in Google (as opposed to letting Google pick for you). If you want the page to never be indexed you can use a robots NOINDEX meta tag or a robots.txt file.
I don't know if I understand the rest of your question, tho. Are you asking if you should canonical your pagination to the main category landing page? If so, unless the content is clearly duplicate, I don't know that it will make a lot of difference. Remember, canonicals just shape what shows on your site. It could be advantageous to canonical your pagination but what if what I was searching for was on page 4? Could also hurt you if not done properly.

Url structure on product pages - Should we apply canonicalized links in breadcrumbs or entry folders
We have products in the that go into mulitiple categories on our e-commerce site. But of course, each product is only canonicalized to one category. My question is: what should the breadcrumbs look like when users access a product from a non-canonicalized/primary category ?Should we apply canonicalized links in breadcrumbs or entry folders? For example: Let´s say we have product called "glacier hiking in the alps". It is in two categories; 1) glacier hiking 2) mountain tours. And is canonicalized to the glacier hiking category. If a user accesses it from the mountain tours category, should the url/breadcrumbs look like this: www.example.com/glacier-hiking/glacier-hiking-in-the-alps (because that is the canonicalized version) Or should it look like like this: www.example.com/mountain-tours/glacier-hiking-in-the-alps (because that is where the user came from) Thanks in advance!

[e-commerce] Should I index product variants?
Hi guys, I have e-commerce site, that sells car tires. I was wondering would I benefit from making all Product Variants ( for example each tire size ) as different page, that has link to the main product to provide some affiliation, or should I make each variant noindex, and add rel=canonical to the main product. The benefits from having each variant indexed can be many: greater click through rate more relative results for customers etc. But I'm not sure how to handle the duplicate content issue ( in this case, only the title, URL and H1 can be different ). Regards.

Duplicate Content on Product Pages
I'm getting a lot of duplicate content errors on my ecommerce site www.outdoormegastore.co.uk mainly centered around product pages. The products are completely different in terms of the title, meta data, product descriptions and images (with alt tags)but SEOmoz is still identifying them as duplicates and we've noticed a significant drop in google ranking lately. Admittedly the product descriptions are a little bit thin but I don't understand why the pages would be viewed as duplicates and therefore can be ranked lower? The content is definitely unique too. As an example these three pages have been identified as being duplicates of each other. http://www.outdoormegastore.co.uk/regatta-landtrek-25l-rucksack.html http://www.outdoormegastore.co.uk/canyon-bryce-adult-cycling-helmet-9045.html http://www.outdoormegastore.co.uk/outwell-minnesota-6-carpet-for-green-07-08-tent.html

Indexing an e-commerce site
Hi all, My client babyblingstreet.com. She sells baby and toddler clothing. Now a lot of the links on her site contain the same products. For instance: if you go to "What's new" you can find those same products in let's say her "Sale Items" link category. The real problem with this is let's say my client sells a green dress and someone accesses it through the "baby and toddler dresses" category. And let's say this URL has 10 links pointing to it. Now, let's say someone else accesses this same green dress through the "What's new" category. And let's say this particular URL has 10 links pointing to it. Instead of having 20 links pointing to one URL about the green dress, I now have 10 links pointing to one URL and 10 pointing to another URL even though both URLs feature the exact same green dress. In this particular example I would want to make the URL of the green dress in the "baby and toddler clothing" section be the canonical URL. So that means I would have to use this canonical tag on the green dress URL that's in the "what's new" category and let's say also the "sale items" category. This could get very tedious if my client has 200+ products. So I am wondering if I have to place a canonical tag on every URL that displays the green dress? More importantly, I would like to know other people's strategies for indexing e-commerce sites that have the same product featured in multiple categories throughout the site. I hope this makes sense. Thanks for your time.

How to keep the link juice in E-commerce to an "out of stock" products URL?
I am running an e-commerce business where I sell fashion jewelry. We usually have 500 products to offer and some of them we have only one in stock. What happens is that many of our back links are pointed directly to a specific product, and when a product is sold out and no longer is in stock the URL becomes inactive, and we lose the link juice. What is the best practice or tool to 301-redirect many URLs at the same time without going and changing one URL at a time? Do you have any other suggestions on how to manage an out of stock product but still maintain the link juice from the back link? Thanks!

Index.php canonical/dup issues
Hello my fellow SEOs! I would LOVE some additional insight/opinions on the following... I have a client who is an industry leader, big site, ranks for many competitive phrases, blah blah..you get the picture. However, they have a big dup content/canonical issue. Most pages resolve with and without the /index.php at the end of the URL. Obviously this is a dup content issue but more importantly they SEs sometimes serve an "index.php" version of the page, sometimes they don't, and it is constantly changing which version it serves and the rank goes up and down. Now, I've instructed them that we are going to need to write a sitewide redirect to attempt a uniform structure. Most people would say, redirect to the non index.php version buttttt 1. The index.php pages consistently outperforms the non index.php versions, except the homepage. 2. The client really would prefer to have the "index.php" at the end of the URL The homepage performs extremely well for a lot of competitive phrases. I'd like to redirect all pages to the "index.php" version except the homepage and I'm thinking that if I redirect all pages EXCEPT the homepage to the index.php version, it could cause some unforeseen issues. I can not use rel=canonical because they have many different versions of the their pages with different country codes in the URL..example, if I make the US version canonical, it will hurt the pages trying to rank with a fr URL, de URL, (where fr/de are country codes in the URL depending where the user is, it serves the correct version). Any advice would be GREATLY appreciated. Thanks in advance! Mike
