Head of Google Spam Search, Matt Cutts has recently answered an interesting question in the Webmaster Help video. On asking "How has query syntax changed since voice search has become more popular?”, Cutts discussed about the trends that Google is currently seeing.
Explaining further, Cutts said, "If you have something coming in the form of voice, people are more likely to use a natural language. The speaker will be less likely to use keywords. Google wants to get better at conversational search and wants to give your answers directly, in case you are looking for some sort of a conversational mode".
Voice search is a growing trend on mobile and Google has recently launched the conversational search feature for the desktop.
Matt said, “We will have to change our mental viewpoint. If we normally add words onto the query, we are using "and" between each of the words. So, the more words you add, the more "and" are present in between, and fewer results you get. The reason behind is that only a few pages have the words that you entered in the query. However, the more you talk, the more results you get. Therefore, users will have to summarize what they are looking for and this will match the overall idea".
Cutts added, "If you take voice search to a limit, you can try to do a query on Google using the entire document or something like that. And rather than match only the documents that have thousands of those words. Ideally, you would say, what's the person looking for? May be the documents are telling a lot about the topic but try to distill down what the important parts are and search for that. This is definitely the case query syntax has changed and it will continue to change. Google allow people to search for images by dragging and dropping an image on Google Image Search. So, people want to search in all possible ways. They do not want to think about keywords, if they can avoid it".
Google hopes to get better at understanding the user's intent while trying to match that up and finding the best information or answers or documents, the user is looking for.Matt Cutts on How Query Syntax has Changed After Voice Search Became Popular!,
