For the last 3 years our website has been listed perfectly in Google, I suspect because I supply a sitemap directly for webmaster tools to make use of. In all of this time, if you ever did a site
urwebsite you would get our complete listings with all meta titles and descriptions correctly shown. Approximately 4 weeks ago however everything changed. When you now try a site
urwebsite you see all of our listings but 50% of the time the meta titles have been changed. They are now showing as our 'meta title - Something Extra'. When I click on the link it goes to the correct page with the meta title as it should be. I have searched on page and in code and on most occasions there is no mention of the keyword anywhere to be found that Google has decided to attach to the page.
My questions therefore are:
1. Has anyone else seen this happen to their websites?
2. Can anchor text on in bound links somehow affect what they decide to display?
3. Does it sound out of the ordinary and should I be concerned with contacting them?
The problem I have is that I now have a few pages which show the meta title in Google as:
'Brand X blah blah blah - Brand Y'
So Google has decided to attach a competing brand name to the end of a product from another brand from our website. Before it was just happening to categories which looked odd but didn't cause me to worry so much.
Any help appreciated.
