ECommerce Problem with canonicol , rel next , rel prev
-
Hi
I was wondering if anyone willing to share your experience on implementing pagination and canonical when it comes to multiple sort options . Lets look at an example
I have a site example.com ( i share the ownership with the rest of the world on that one ) and I sell stuff on the site
I allow users to sort it by date_added, price, a-z, z-a, umph-value, and so on . So now we have
- example.com/for-sale/stuff1?sortby=date_added
- example.com/for-sale/stuff1?sortby=price
- example.com/for-sale/stuff1?sortby=a-z
- example.com/for-sale/stuff1?sortby=z-a
- example.com/for-sale/stuff1?sortby=umph-value
- etc
example.com/for-sale/stuff1 **has the same result as **example.com/for-sale/stuff1?sortby=date_added ( that is the default sort option )
similarly for stuff2, stuff3 and so on. I cant 301 these because these are relevant for users who come in to buy from the site. I can add a view all page and rel canonical to that but let us assume its not technically possible for the site and there are tens of thousands of items in each of the for-sale pages. So I split it up in to pages of x numbers and let us assume we have 50 pages to sort through.
- example.com/for-sale/stuff1?sortby=date_added&page=2 to ...page=50
- example.com/for-sale/stuff1?sortby=price&page=2 to ...page=50
- example.com/for-sale/stuff1?sortby=a-z&page=2 to ...page=50
- example.com/for-sale/stuff1?sortby=z-a&page=2 to ...page=50
- example.com/for-sale/stuff1?sortby=umph-value&page=2 to ...page=50
- etc
This is where the shit hits the fan. So now if I want to avoid duplicate issue and when it comes to page 30 of stuff1 sorted by date do I add
- rel canonical = example.com/for-sale/stuff1
- rel next = example.com/for-sale/stuff1?sortby=date_added&page=31
- rel prev = example.com/for-sale/stuff1?sortby=date_added&page=29
or
- rel canonical = example.com/for-sale/stuff1?sortby=date_added
- rel next = example.com/for-sale/stuff1?sortby=date_added&page=31
- rel prev = example.com/for-sale/stuff1?sortby=date_added&page=29
or
- rel canonical = example.com/for-sale/stuff1
- rel next = example.com/for-sale/stuff1?page=31
- rel prev = example.com/for-sale/stuff1?page=29
or
- rel canonical = example.com/for-sale/stuff1?page=30
- rel next = example.com/for-sale/stuff1?sortby=date_added&page=31
- rel prev = example.com/for-sale/stuff1?sortby=date_added&page=29
or
- rel canonical = example.com/for-sale/stuff1?page=30
- rel next = example.com/for-sale/stuff1?page=31
- rel prev = example.com/for-sale/stuff1?page=29
None of this feels right to me . I am thinking of using GWT to ask G-bot not to crawl any of the sort parameters ( date_added, price, a-z, z-a, umph-value, and so on ) and use
- rel canonical = example.com/for-sale/stuff1?sortby=date_added&page=30
- rel next = example.com/for-sale/stuff1?sortby=date_added&page=31
- rel prev = example.com/for-sale/stuff1?sortby=date_added&page=29
My doubts about this is that , will the link value that goes in to the pages with parameters be consolidated when I choose to ignore them via URL Parameters in GWT ? what do you guys think ?

Thanks Peter .

Thanks for your input.
IMHO...If I exclude ? , then paginated pages like ?page=xx wont be crawled , thus the rel=next prev tags on the page are rendered useless.

Yeah, it gets ugly fast, and even done "by the book" you're often going to need to monitor your index and make adjustments, I've found. That said, the official Google stance (at least the last I heard) is that you should canonical to the page with no parameters and rel=prev/next to the parameterized versions (your 2nd-to-last example):
- rel canonical = example.com/for-sale/stuff1?page=30
- rel next = example.com/for-sale/stuff1?sortby=date_added&page=31
- rel prev = example.com/for-sale/stuff1?sortby=date_added&page=29
See the bottom of this Google blog post:
http://googlewebmastercentral.blogspot.com/2011/09/pagination-with-relnext-and-relprev.html
The other option would be to use rel=prev/next on the paginated URLs and then dynamically Meta Noindex anything with parameters. Honestly, it really depends on what works, and it can take a while to sort out. Also, keep in mind that Bing doesn't handle rel=prev/next quite the same way as Google.

First of all: did you check this video? http://www.youtube.com/watch?feature=player_detailpage&v=njn8uXTWiGg

You can set the ? as exclude from searches in Webmaster Tool
-
I would always set rel="canonical" to the main page (category page): .
Check how big sites work with this issue.

Another Duplicate Content - eCommerce Question!
We are manufacturers of about 15 products and our website provides information about the products. We also offer them for sale on the site. Recently we partnered with a large eCommerce site that sells many of these types of products. They lifted descriptions from our site for theirs and are now selling our products. They have higher DA than us. Will this cause a ranking problem for us? Should we write unique descriptions for them? Thanks!

Having Problems to Index all URLs on Sitemap
Hi all again ! Thanks in advance ! My client's site is having problems to index all its pages. I even bought the full extension of XML Sitemaps and the number of urls increased, but we still have problems to index all of them. What are the reasons? The robots.txt is open for all robots, we only prohibit users and spiders to enter our Intranet. I've read that duplicate content and 404's can be the reason. Anything else?

Importance of WMT change of address and problem doing it
Hi, How important is it to submit a change of address in WMT? I say that because I am having problems doing it so wondered if it was worth the hassle in trying to fix it. I am getting the error: "We couldn't verify website.co.uk. To submit a change of address, website.co.uk must be verified using the same method as www.website.co.uk. Add website.co.uk to your account and verify ownership, then try again." I have looked on the web to try and find an answer and have come across 2 suggestions: You might have lost the verification with the redirect. If you used a metatag on the home page, the home page is now redirecting. If you had uploaded a verification text file, that file is probably now gone and redirecting as well. You probably need to re-verify the site. Either re-upload the text file and configure it not to redirect (may be difficult) or use the DNS server verification method. You need to verify the non www. version of the website because that's the way Google like it. Not sure why solution 2 would be necessary but it does seem to be what WMT are getting. Because the site already redirects, 1 would then come in to play. Is it worth persevering with because IT will be getting a long list of stuff to do from me as it is.... Thanks all

Similar pages: noindex or rel:canonical or disregard parameters?!
Hey all! We have a hotel booking website that has search results pages per destinations (e.g. hotels in NYC is dayguest.com/nyc). Pages are also generated for destinations depending on various parameters, that can be star rating, amenities, style of the properties, etc. (e.g. dayguest.com/nyc/4stars, dayguest.com/nyc/luggagestorage, dayguest.com/nyc/luxury, etc.). In general, all of these pages are very similar, as for example, there might be 10 hotels in NYC and all of them will offer luggage storage. Pages can be nearly identical. Come the problems of duplicate content and loss of juice by dilution. I was wondering what was the best practice in such a situation: should I just put all pages except the most important ones (e.g. dayguest.com/nyc) as noindex? Or set it as canonical page for all variations? Or in google webmaster tool ask google to disregard the URLs for various parameters? Or do something else altogether?! Thanks for the help!

Rel="no follow" for All Links on a Site that Charges for Advertising
If I run a site that charges other companies for listing their products, running banner advertisements, white paper downloads, etc. does it make sense to "no follow" all of their links on my site? For example: they receive a profile page, product pages and are allowed to post press releases. Should all of their links on these pages be "no follow"? It seems like a gray area to me because the explicit advertisements will definitely be "no followed" and they are not buying links, but buying exposure. However, I still don't know the common practice for links from other parts of their "package". Thanks

301 redirect problems on site not yet moved
I have re-designed one of my sites, the old site is all static pages on a Windows server, I have made the new sites and it is on a new server and is running on Wordpress. I have just finished testing it and so am nearly ready to switch over the nameservers to the new server, however I'm having some problems with 301 redirects. I have tried to set up a few 301 redirects on the new server to test before I change nameservers but they don't appear to be working. I would have imagined that they should (even though the actual page isn't hosted on the new server) or am I being very stupid here and I can't test a 301 redirect until the nameservers have been changed. Redirect 301 /magazines.htm http://.../~account/magazine-freebies Obviously the above with the stars (*) is the server address and route to my account.

Problems with changing the page title on Wordpress Site...
The website is http://www.masterpieceinteriors.co.uk/ I'm not sure why the homepage title is reading 'masterpieces' in Google but looks fine here. There seem to be 2 versions of the homepage coming up in google - you can see them both by searching 'masterpieceinteriors' and then 'masterpiece interiors'. Some help would be hugely appreciated!

Any input / pointers for my upcoming Ecommerce move?
I posted this as a reply on my other question, but never got another responce... I am basically moving ecommerce platforms to answer your question. I am keep the same domain (www.stbands.com). If you want to get even more specific i am moving from storesonline to corecommerce. Here's some more info: All meta tags, URLS, content is virtually going to be the same except my product pages and normal pages will end with .html, however my category pages will still be /categoryname (like a directory). My category URLS seem to build in a mod re-write fashion, which I hear is better for SEO (like /sweatbands/head-sweatbands/). I have set all my pages to use the rel=cananical tag, so if you are on the category /sweatbands/head-sweatbands/ it cananicals back to /head-sweatbands The images are changing names as I upload them on a product because it auto creates new sizes. This differs from our old host and may affect our vertical image rankings. Should I 301 the image URLS? I am keeping the www. in my domain name, as opposed to just domain.com to keep everything the same. CoreCommerce automatically seems to make my products uppercase in the URL as they are in the title, but the url works both lowercase and uppercase so its not case sensitive. This is just an overview of some things I think I have most of my bases covered, but i'm aiming for a april 1st launch / move for the new site. Do you guys have any other pointers / suggestions?
