After reading this: "Keep the links on a given page to a reasonable number" [Googkle official site]
And this: "Users often dislike link-heavy pages too, so before you go overboard putting a ton of links on a page, ask yourself what the purpose of the page is and whether it works well for the user experience." [Matt Cutts official blog]
I'm wondering how to keep links on a given page to a reasonable number for a generic e-commerce site, in order to make Google happy too.
Usually these type of sites contains a left menu packed with all the products/articles in the shop catalog divided by categories/sub-categories. Each sub-category has naturally a link to it (on some sites even the main category have a link showing a page with the sub-categories listed as page contents)
Shops/companies usually have many categories/sub-categories to show, so generally these left menu are big with many, many links. And since these left menu are repeated in each page (1) how could we keep the amount of links to a reasonable number?
Any SEO considerations and suggestions are well accepted too in your answer (as always).
(1) note - I think these big menus repeated in all pages don't make the website less user friendly I'm talking about tree menus like this one for instance
Actually I think the opposite: I can't stand navigating sites that change the position or the flow/contents of menus while I'm navigating. And you?
