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?
