Auto-loading content via AJAX - best practices
-
We have an ecommerce website and I'm looking at replacing the pagination on our category pages with functionality that auto-loads the products as the user scrolls. There are a number of big websites that do this - MyFonts and Kickstarter are two that spring to mind.
Obviously if we are loading the content in via AJAX then search engine spiders aren't going to be able to crawl our categories in the same way they can now. I'm wondering what the best way to get around this is.
Some ideas that spring to mind are:
-
detect the user agent and if the visitor is a spider, show them the old-style pagination instead of the AJAX version
-
make sure we submit an updated Google sitemap every day (I'm not sure if this a reasonable substitute for Google being able to properly crawl our site)
Are there any best practices surrounding this approach to pagination? Surely the bigger sites that do this must have had to deal with these issues?
Any advice would be much appreciated!

Hi Paul,
Pagination is always a bit of a sticky area!
Firstly I certainly wouldn't do any user agent detection, you don't wanna get busted for cloaking when you aren't even up to anything that naughty.
A nice way i've seen this handled (for wordpress sites although the idea can work on any site) is with the wordpress infinite scroll plugin : http://wordpress.org/extend/plugins/infinite-scroll/
That basically leaves the site as it is for non-javascript web browsers (so with page 1, 2 3 etc.) but if you have js enabled (i.e. not a spider bot) it will keep scrolling the page. This functionality could I guess be changed to create a pagination effect.
Tie this is with some rel="prev" and rel="next" markeup (http://googlewebmastercentral.blogspot.co.uk/2011/09/pagination-with-relnext-and-relprev.html) and I think that is certainly one way to fix the problem.
Another way could be using similar markup for a 'View All' page : http://googlewebmastercentral.blogspot.co.uk/2011/09/view-all-in-search-results.html
Hope that helps!

Geo Targeting Content Question
Hi, all First question here so be gentle, please My question is around geo targeted dynamic content; at the moment we run a .com domain with, for example, an article about running headphones and then at the end - taking up about 40% of the content - is a review of some people can buy, with affiliate links. We have a .co.uk site with the same page about running headphones and then 10 headphones for the UK market. Note: rel alternative is used on the pages to point to each other, therefore (hopefully) removing duplicate content issues. This design works well but it involves having to build links to two pages, in the case of this example. What we are thinking of doing is to just use the .com domain and having the product page of the page served dynamically, ie, people in the UK see UK products and people in US see US products. What are people's thoughts on this technique, please? From my understanding, it wouldn't be any problem with Google for cloaking etc because a googlebot and a human from the same country will see the same content. The site is made in Wordpress and has <....html lang="en-US"> (for the .com) in the header. Would this cause problems for the page ranking in the UK etc? The ultimate goal of doing this would be to reduce link building efforts by halving the number of pages which links would have to be built for. I welcome any feedback. Many thanks

Content in Accordion doesn't rank as well as Content in Text box?
Does content rank better in a full view text layout, rather than in a clickable accordion? I read somewhere because users need to click into an accordion it may not rank as well, as it may be considered hidden on the page - is this true? accordion example: see features: https://www.workday.com/en-us/applications/student.html

Redirects - How Best to do this ?
Hi I am looking to close Website A which has many pages. I would like to keep the home page and add some great content to it with a link pointing to Website B. As for all the other pages excluding the home page , how is it best to approach them on Website A. Should I redirect them all to the home page of Website A which will tell Google thoose Pages are no longer needed and to prevent the visitors from seeing a 404? My Main aim here is to not lose any visitors to Website A by sending them to Website B but also to hopefully pass any Page strength from Website A to Website B Thanks Adam

Duplicate video content question
This is really two questions in one. 1. If we put a video on YouTube and on our site via Wistia, how would that affect our rankings/authority/credibility? Would we get punished for duplicate video content? 2. If we put a Wistia hosted video on our website twice, on two different pages, we would get hit for having duplicate content? Any other suggestions regarding hosting on Wistia and YouTube versus just Wistia for product videos would be much appreciated. Thank you!

Duplicate Content and Canonical use
We have a pagination issue, which the developers seem reluctant (or incapable) to fix whereby we have 3 of the same page (slightly differing URLs) coming up in different pages in the archived article index. The indexing convention was very poorly thought up by the developers and has left us with the same article on, for example, page 1, 2 and 3 of the article index, hence the duplications. Is this a clear cut case of using a canonical tag? Quite concerned this is going to have a negative impact on ranking, of course. Cheers Martin

Duplicate content?
I have a question regarding a warning that I got on one of my websites, it says Duplicate content. I'm canonical url:s and is also using blocking Google out from pages that you are warning me about. The pages are not indexed by Google, why do I get the warnings? Thanks for great seotools! 3M5AY.png

Canonical Link for Duplicate Content
A client of ours uses some unique keyword tracking for their landing pages where they append certain metrics in a query string, and pulls that information out dynamically to learn more about their traffic (kind of like Google's UTM tracking). Non-the-less these query strings are now being indexed as separate pages in Google and Yahoo and are being flagged as duplicate content/title tags by the SEOmoz tools. For example: Base Page: www.domain.com/page.html

Tracking: www.domain.com/page.html?keyword=keyword#source=source Now both of these are being indexed even though it is only one page. So i suggested placing an canonical link tag in the header point back to the base page to start discrediting the tracking URLs: But this means that the base pages will be pointing to themselves as well, would that be an issue? Is their a better way to solve this issue without removing the query tracking all togther? Thanks - Kyle Chandler0
