There's been a bit floating around the internet recently regarding Google changing it's algorithm to penalise pages using hidden content. The theory behind it is that users are seeing search results with the content they want but on click through that content isn't on the actual page as its hidden and is only there to boost rankings, making users then question the accuracy of google's search results. A knock on affect of this is that pages using tabs to display content are likely to be penalised. I've seen it first hand as pages that we've launched since this change which incorporate tabbed content have ranked really badly on Google but removing the tabs in favor of one really long page has made a dramatic difference to page ranking. The past few days I've been thinking over this issue and I'm wondering if the method of hiding content within tabs could change the way google ranks it? For example, pages I've had issue with have had content within tabs that have a display:none class applied which a .click(function() add/removes as required to browse the page. Has anyone looked into using jQuery .hide() in the page footer to hide tabs as a page loads? In theory the content will be visible until the footer loads but is that enough to keep google happy? Anyone have any thoughts on this?
