Google adds suffix to title -

i wondering why google adds suffix website, don't know why specific word. website talking has sub domain. keep post free of ads, let's domain is:

so when search website on google this:

"lorem ipsum| specific page title - my_name"

original page title:

<title>lorem ipsum | specific page title</title>

maybe google got word here, why?:

at bottom / footer of each website include following code:

<div class="container">     <p class="any-class"><b>my_name</b>     </p> </div>

the main website http://my-name.com/ has following code:

    <div class="title">     <h1 class="title-text">my_name</h1>     <p class="title-sub"><b>this is</b>a subtitle</p>     </div>

and

<title>my_name</title>

where , why did google word from? how can change suffix (if possible).

thanks ideas, jonas.

if using entirely different title tags pages, google tries add common string. done prevent title spamming.

for example if /index.html has title “foobar - welcome website“, google may add “foobar“ pages short or disconnected titles.
