Category Pages - Canonical, Robots.txt, Changing Page Attributes
-
A site has category pages as such: www.domain.com/category.html, www.domain.com/category-page2.html, etc...
This is producing duplicate meta descriptions (page titles have page numbers in them so they are not duplicate). Below are the options that we've been thinking about:
a. Keep meta descriptions the same except for adding a page number (this would keep internal juice flowing to products that are listed on subsequent pages). All pages have unique product listings.
b. Use canonical tags on subsequent pages and point them back to the main category page.
c. Robots.txt on subsequent pages.
d. ?
Options b and c will orphan or french fry some of our product pages.
Any help on this would be much appreciated. Thank you.

I see. I think the concern is with duplicate content though, right?
-
Either way, it will be tough to go that route and still get indexed. Its a pagination issue that everyone would like a solution to, but there just isnt one. It wont hurt you to do this, but wont ultimately get all those pages indexed like you want.
-
Disagree. I think you are missing out big time here- category pages are the bread and butter for eCommerce sites. Search engines have confirmed that these pages are of high value for users, and it gets you a chance to have optimized static content on a page that also shows product results. All the major e retailers heavily rely on these pages (Amazon, ebay, zappos, etc...)
-
Sorry, I don't think I clarified. The page title and meta descriptions would be unique, however they would be almost the same except for it saying "Page [x}" somewhere within it.
-
Option A doesnt do anything for you. I think the search engines flag duplicated title tags, even with different products on the page.
-
Thanks for the comprehensive response, Ryan; really great info here!
Would option A be out of the question in your mind due to the fact that the page attributes would be too similar even though unique content is on all the subsequent category pages? I know this method isn't typical, however, it would be the most efficient way to address.
Note: A big downside to this is also the fact that we will have multiple pages targeting the same keyword, however, since internally and externally, the main category pages are getting more link love, would it still hurt to have all those subsequent pages getting indexed?

Ahh... the ultimate IA question that still doesnt have a clear anwer from the search engines. A ton of talk about this at the recent SMX Advanced at Seattle (as is with almost every one). I will try and summarize the common sentiment that i gathered from other pros. I will not claim that this is the correct way, but for now this is what i heard a bunch of people agree on:
- No index, follow the pagination links for all except page 1
- Do not block/hand it with robots.txt (in your case, you realyl cant since you have no identifying parameters in your url)
- If you had paginated parameters in the url you can also manage those in the Google & Bing WMT by telling the SE to ignore those certain parameters.
- Canonical to page 1 was a strategy that some retailers were using, and other want to try. Google reps tried to say this is not the way to do it, but others claim success from it.
- If you have a "View All" link that would display all the products in a longer form on a single page, canonical to that page (if its reasonable)
Notes: Depending on how your results/pages are generated, you will need to remember that they probably arent passing "juice". Any dynamic content is usually not "flow through" links from an SEO perspective (or even crawled sometimes).
The better approach to not orphaning your product pages is finding ways to link to them from other sources besides the results pages. For larger sites, its a hassle, buts thats a challenge we all face Here are some SEO tips for attacking the "orphan" issue:
- If you have product feeds, create a "deal" or "price change" feed. Create a twitter account that people can sign up for to follow these new deals or price changes on products. Push in your feed into tweets, and these will link to your product page, hence creating an in-link for search engines to follow.
- Can do the same with blogs or facebook, but not on a mass scale. Something a bit more useful for users like "top 10 deals of the week) and link to 10 products, or "Favorites for gifts" or something. over time, you can keep track of which product you recommend, and make sure you eventually hit all your products. Again, the point is creating at least 1 inbound link for search engines to follow.
- Create a static internal "product index page" (this is not for your sitemap page FYI) where either by category or some other structure, you make a static link to every product page you have on the site. Developers can have these links dynamically updated/inserted with some extra effort which will avoid manually needing to be updated.
- Create a xml sitemap index. Instead of everything being clumped into 1 xml sitemap for your site, try creating a sitemap index and with your product pages in their own sitemap. This may help with indexing those pages.
Hope that helps? Anyone else want to chime in?

I think that generally speaking you want to block search engines from indexing your category pages (use your sitemap and robots.txt to do this). I could be totally wrong here but that is how I setup my sites.

Stub category pages (dupe warning)
Hi I have a number of highly ranked category pages. However, at times these contain no products for a few weeks, etc. They are being flagged as duplicate content as they are just stub pages when they have no products, with the same "No products found" message. I don't want to risk 'noindex' ing the pages though - because as soon as they have products in, they become valuable pages and I would hate to lose a good ranking. Should I just leave them as-is and ignore the dupe warnings?

Is a 301 Redirect and a Canonical Tag on Uppercase to Lowercase Pages Correct?
We have a medium size site that lost more than 50% of its traffic in July 2013 just before the Panda rollout. After working with a SEO agency, we were advised to clean up various items, one of them being that the 10k+ urls were all mixed case (i.e. www.example.com/Blue-Widget). A 301 redirect was set up thereafter forcing all these urls to go to a lowercase version (i.e. www.example.com/blue-widget). In addition, there was a canonical tag placed on all of these pages in case any parameters or other characters were incorporated into a url. I thought this was a good set up, but when running a SEO audit through a third party tool, it shows me the massive amount of 301 redirects. And, now I wonder if there should only be a canonical without the redirect or if its okay to have tens of thousands 301 redirects on the site. We have not recovered yet from the traffic loss yet and we are wondering if its really more of a technical problem than a Google penalty. Guidance and advise from those experienced in the industry is appreciated.

Use Canonical or Robots.txt for Map View URL without Backlink Potential
I have a Page X with lots of unique content. This page has a "Map view" option, which displays some of the info from Page X, but a lot is ommitted.

I don't see any back links coming to Map View URL Should Map View page have unique H1, title tag, meta des?

Is it best to condense 2 similar category pages?
After reading Rand's great article about building Seo focused pages to serve topics, not keywords (http://moz.com/blog/topics-people-over-keywords-rankings-whiteboard-friday ) I started looking at my site. Question: I have 2 very similar category pages, orginally built to go after similar but different keyword terms. For example, one is: domain.com/blue-rings.html and the other is domain.com/blue-bands.com. (bridal jewelry) "Blue" is just a hypothetical type. At one time I could rank for "blue-rings" and "blue-bands". But with google changes, I think it's better to focus on a general term, right? Not set up similar pages, with same product, for very similar keywords. I'm thinking that having these 2 pages could be actually hurting, as they are competing with each other. Any recommendations? Thanks folks! Ron

Rel=canonical on image pages
Hi, Im working on a Wordpress hosted blog site. I recently did a "site:search" in Google for a specific article page to make sure it was getting crawled, and it returned three separate URLs in the search results. One was the article page, and the other two were the URLs that hosted the images that are found in the article. Would you suggest adding the rel=canonical tag to the pages that host the images so they point back to the actual context article page? Or are they fine being left alone? Thank you!
