Most websites link from every page to the frontpage via a href placed in a logo or home button.
I'm maintaining this website where there isn't such a link per se. Navigation to the homepage is done via a button attached to a form. It makes sense in the context, as the entire menu that the button belongs to is made of more buttons and inputs that dinamically load and sort content.
Is there any loss from a SEO perspective (such as not enough link juice not being passed to the homepage etc.) or, conversely, a gain (like more juice to share between the other pages)? So should I recommend replacing the button with a classical link or just leave it be?
