Canonical use when dynamically placing items on "all products" page
-
Hi all,
We're trying to get our canonical situation straightened out. We have a section of our site with 100 product pages in it (in our case a city with hotels that we've reviewed), and we have a single page where we list them all out--an "all products" page called "all.html."
However, because we have 100 and that's a lot for a user to see at once, we plan to first show only 50 on "all.html." When the user scrolls down to the bottom, we use AJAX to place another 50 on the page (these come from another page called "more.html" and are placed onto "all.html"). So, as you scroll down from the front end, you see "all.html" with 100 listings.
We have other listings pages that are sorted and filtered subsets of this list with little or no unique content. Thus, we want to place a canonical on those pages.
Question: Should the canonical point to "all.html"? Would spiders get confused, because they see that all.html is only half the listings? Is it dangerous to dynamically place content on a page that's used as a canonical? Is this a non-issue?
Thanks,
Tom

Hi Tom
(Great name)
If you preference is to have the all.html page (and more.html page) indexed and potentially ranked, rather than the subset/filtered pages, then you should do just as you say.
It's worth double checking if your "more.html" page is being indexed as well (just paste the URL into a Google search bar). If so, if you can point any of the subset pages to that one, if it is more accurate, then that's an option. Google, when crawling the page, won't see the dynamically loaded content (at least I think - you can test this by pasting the URL into the SEO Browser, running a 'simple' analysis, and seeing what the Googlebot sees), so it might be wise to point the subset pages to the URL that it matches most closely.
If that isn't an option though, there won't be an issue with adding the canonicals to the subset pages to point to the all.html - even if the content isn't an exact match. You're taking steps to prevent any duplicate indexation and Google will appreciate that. Another idea, which is probably more robust, is to add the tag to the code in the HTML, if the listing pages physically exist and are not dynamically created with search queries.
Having said that, I do believe your solution would work fine. Hope this helps

Seeking subdomain usage and related SEO advice... I'd like to use multiple subdomains for multiple landing pages all with content related to the main root domain. Why?...Cost: so I only have to register one domain. One root domain for better 'branding'. Multiple subdomains that each focus on one specific reason & set of specific keywords people would search a solution to their reason to hire us (or our competition).

Is it ok to add rel=CANONICAL into the desktop version on top of the rel="alternate" Tag (Mobile vs Desktop version)
Hi mozzers, We launched a mobile site a couples months ago following the parallel mobile structure with a URL:m.example.com The week later my moz crawl detected thousands of dups which I resolved by implementing canonical tags on the mobile version and rel=alternate onto the desktop version. The problem here is that I still also got Dups from that got generated by the CMS. ?device=mobile ?device=desktop One of the options to resolve those is to add canonicals on the desktop versions as well on top of the rel=alternate tag we just implemented. So my question here: is it dangerous to add rel=canonical and rel=alternate tags on the desktop version of the site or not? will it disrupt the rel=canonical on mobile? Thanks

High number of items per page or low number with more category pages?
In SEO terms, what would be the best method: High number of items per page or low number with more pages? For example, this category listing here: http://flyawaysimulation.com/downloads/90/fsx-civil-aircraft/ It has 10 items per page. Would there be any benefit of changing a listing like that to 20 items in order to decrease the number of pages in the category? Also, what other ways could you increase the SEO of category listings like that?
