I recently googled some key words related to my site and found that the shop name (or part of it) was missing from the google description and I had dropped in ranking (possible side effect?). The full shop name used to show up in the Google description but now it seems to be missing.
I.e my site is thefruitstore.com (example) and the site name was "The Fruit Store - the number 1 fruit store in Canada".
Now when I google it it only shows
The Fruit Store (no additional description - the bold sentence doesn't appear).
When I go to seetings I can still the full shop name i.e "The Fruit Store - the number 1 fruit store in Canada"
