When one shares a
resource using the +1 button, Google attempts to extract a page title, a
description of the page and a thumbnail image from that resource. This
preview is then used on the Google+ post page (and one would think that the
same extraction logic is used when linking to a page directly from Google+, but
I have yet to verify this with testing).
According to Google's technical
documentation for the +1 button, the data is extracted from the
target URL in one of four ways, listed in order of precedence.
1.
Schema.org microdata
2.
Open Graph protocol
3.
Meta "title"
and "description" tags
4.
Best guess from page
content
<!-- Update your html tag to include the itemscope and itemtype
attributes -->
<html itemscope
itemtype="http://schema.org/LocalBusiness">
<!-- Add the following three tags inside head -->
<meta itemprop="name" content="title of your
content">
<meta
itemprop="description" content="description">
<meta itemprop="image" content="image
url">
