Knowledge Graph Dropdown Hit the Local SERPs at Google
It appears that Google is now including Knowledge Graph dropdowns (see below) inline in both general and local search results.
Knowledge Graph results, as you likely know, typically pulls the data it shows from available Wikipedia information as well as Google+ profiles (a good reason to ensure your G+ information is up to date). Read Website Magazine's previous coverage of the Knowledge Graph here and here (and most recently here). The new Knowledge Graph integration, which really is just an extension of the current program to feature for more local businesses it seems, provides a link on the same line as a listing's URL - upon clicking the dropdown, information about the company is then provided.
While some have suggested that the Knowledge Graph provides "mostly irrelevant, distracting, repetitive" and non-specific results, the majority of end-users don't really seem to mind - and that's reason enough for Google to keep the feature functional and even extend its inclusion to more search results.
There's no reason to believe at this point that those sites/pages that have been awarded a Knowledge Graph listing are experiencing better placement or additional traffic, but it's definitely something to keep your digital eye on.
