This week is blended search week on our SEO company blog, and of course, you can’t discuss blended search without understanding the various types of results that you might get, depending on the sort of query you have.  Without further ado:

Traditional Listings - This is the type of basic text listing that we are all used to seeing in the SERPs.

Blog Listings - Similar to the classic text, except for that the listing is from a blog/blog post.  Blog search results are indexed by site feed.

Image Listings - Images/pictures related to the query.

Maps Listings - Maps are being integrated into Google’s search results, and they will likely show up if you are searching for specific business, building, or other singular location.

Video Listings - Video clips related to the query terms, likely from YouTube or Google News.

Financial Listings - Most likely to show up for large, public corporations, these include current stock information.

Book Listings - If your query is related to content in any of Google’s digital book archive, these results are likely to show up near the top of the SERPs.

Product/Catalog Listings -  These show up for queries/search terms that involve a particular retail product; if you have an ecommerce website, you want to make sure that your inventory appears in the relevant product search listings.

Local Listings - If you search for something within a specific area (such as Chicago web design), you’ll likely get a collection of results from Google’s local business center along with a map pin-pointing their exact locations.

PDF Listings - PDF documents are starting to show up in the SERPs in increasing numbers.  That said, if you have any critical content on your site that is only in PDF form, consider the that many of your users may be either unwilling or unable to download it (but that is a usability issue, not an SEO problem).

Of course, this is not an exhaustive list of possible blended search elements, but these are the types of listings that our SEO agency sees most often in the SERPs for our clients’ keywords.  What other unusual elements have you noticed popping up in the results pages lately?
