John Mueller: The one thing that I notice in talking with the mobile indexing folks is that when the e-commerce category pages don’t have any other content at all other than links to the products then it’s really hard for us to rank those pages. So I’m not saying all of that text at the bottom of your page is bad but maybe 90%, 95% of that text is unnecessary but some amount of text is useful to have on a page so that we can understand what this page is about. And at that point you are probably with the amount of text that a user will probably be able to read as well, be able to understand as well. So that’s kind of where I would head in that regard.
