Hey, I am making great steps forward pimping my side for seo, based on the great sparking theme.
Today I noticed that sparkling uses h3 for widget titles in sidebar and footer section.
I have to many h3 heading at my page and I want to reduce the amount via widget title,
as I don´t see any reason why the widget title should use h3.
Optimizating further for seo, I want to substitute h3 for all widget title by standard text.
Using same font, same font size, same background color as today.
I am not sure what exactly it is that you are asking here. Do you want to change all the H3 tags to something else or do you want to edit the H3 tags with a new appearance?
