You can make it so that the title
attribute is removed exclusively on hover, and then re-added. This makes it so that your SEO remains identical, but there is no tooltip text when hovering.
$('a[title]').on('mouseenter', function () {
var $this = $(this);
$this.attr('title-cache', $this.attr('title'));
$this.attr('title', '');
});
$('a[title]').on('mouseleave', function () {
var $this = $(this);
$this.attr('title', $this.attr('title-cache'));
$this.attr('title-cache', '');
});
