Your title is so short that Google has enough room to add a keyword and geographic reference to it?
I would send a thank you note to Google for spotting the underoptimized title tag and proactively fixing it.
This is what I would do: Step 1 - Look at the landing page traffic to the page. Has it improved or dropped?
Step 2 - Ask yourself if the changes that Google made will likely benefit most users or is it overly personalized so it doesn't apply to most users?
Step 3 - Regularly monitor your title tags so you don't end up with underoptimized 20 character title tags.
Step 4 - Is the existing page focused on that new title tag from Google or is this revised title tag a good idea for a new content page to be created?
Step 5 - Don't go crazy. If you start changing every title tag, every single day, Google might think you are trying to manipulate them instead of just honestly optimizing your content and that can be dangerous.
It actually isn't putting "keywords" on all the references of my search engine result.
For example.. like one of my page is coming in google with more than 10 keywords.. Like.. if you type "Blue Widget City Name" .. you get the result with the modified title.. but if you search "Cheap Blue Widget".. it will display my title as it is..
With some queries it modifies the title.. it cuts the actual title.. and ads it's own keyword with it.
