Shareaholic Share Buttons can be customized using data- attributes.
You may customize the content that is shared when people (Title, Link, Image & Summary) by defining "data attributes" within the button code.
To do this, add the following within the div tag embedded in the Share Button code you added to your page:
data-title
data-title='This is my Page Title'
data-link
data-link='https://www.TheURLtoShare.com/page.html'
data-image
data-image='https://www.TheURLtoShare.com/image.jpg'
data-summary
data-summary='Place any notes here.'
data-description
data-description='This is the page description'
Example
<div class='shareaholic-canvas' data-app='share_buttons' data-app-id="xxxxx" data-title='Tiffany T T1 Ring in Rose Gold with Diamonds, 2.5 mm | Tiffany & Co.' data-link='https://www.tiffany.com/jewelry/rings/tiffany-t-t1-narrow-diamond-ring-GRP11292/' data-image='https://media.tiffany.com/is/image/Tiffany/EcomItemL2/tiffany-tt1-ring-67795253_1010336_ED_M.jpg' data-description='Pavé diamonds illuminate one side of this ring, adding a striking radiance to the design. A reinvention of a Tiffany icon, Tiffany T1 designs represent individual strength and perpetual power, worn outwardly to express what lies within.' data-summary='A little hint that this caught my eye!'></div>
For Tumblr:
For Tumblr, you can use data-title and data-link along with the dynamic variable keys.
<div class='shareaholic-canvas' data-app='share_buttons' data-app-id="xxxxx" data-title='{title}' data-link='{permalink}'></div>
Please, see Tumblr's documentation on theme variables for more information.
For WordPress:
For WordPress, you can use data-link along with the function that retrieves the permalink path.
<div class='shareaholic-canvas' data-app='share_buttons' data-app-id="xxxxx" data-link='http://www.your-domain-here.com<?php the_permalink(); ?>'></div>
