I have a website where the front-end developer has added 3 times the menu in the markup, e.g.:
div.menu>home+about+news+contact us"
Update 1: The HTML markup is repeated 3 times
<div class="menu">
<span>home.html</span>
<span>about.html</span>
<span>news.html</span>
<span>contact-us.html</span>
</div>
One is for responsive, one for desktop and another one when you scroll, a bit crazy.
As far as I know this is not a good practice as you have three times the same content on your markup.
But my question then is: Do search engines like Google penalise this or get confused for SEO?
