Google have been busy adding new features – you’ve probably noticed the larger font in the search box for instance.
One thing you should definitely be aware of if you have a Google Maps listing (Local Business Centre) is the new Place Pages, as detailed here. It’s worth having a read of this to understand how it could affect what people see about your business if they find it through a Google Maps search (as often comes at the top of the search results if you search for a business name and/or place). There isn’t that much different from the old Local Business Centre listing, except for the addition of adverts – so you could see your competitors listed alongside your own information! This is what’s happening with some of the ads in the page below:
If you happen to search for a “hot topic”, Google’s list of which is here, you might find the graph of exactly how hot the topic is appearing in the main search results. Details are here, but sadly it only covers the US and Japan at preset.
Finally, you may notice some additional links appearing in search result pages under some website entries. These are designed to take you directly to the section of the page that’s relevant to your search, using in-page (named) anchor tags that the page’s author has included. Why Google are doing this and what it looks like is explained here, whilst what you can do to utilise this as a webmaster is explained here.
