For sure. The quickest way to always & only share the home page using the default AddToAny buttons is add some code to your “Additional JavaScript” box in Settings > AddToAny:
a2a_config.callbacks.push({
share: function(data) {
data.url = 'https://www.example.com/';
data.title = 'Example Site';
return data;
}
});
Just change https://www.example.com/
and Example Site
.
Alternatively, you can disable the default buttons and use the [addtoany]
shortcode in page/post content like:
[addtoany url="https://www.example.com/" title="Example Site"]
