Lots of websites have site menu at the top or on the side. But most of the menu items are usually very generic with text like: Home ¦ Products ¦ Services/Articles ¦ Support ¦ About However, I have seen a few websites with very specific or even narrow menu designs like: Widgets ¦ Blue Widgets ¦ Red Widgets ¦ Green Widgets ¦ Other Keywords... How affective is it for search engine results... assuming that the keywords are sufficiently backed by enough content in the site sections with seo-friendly urls (/widgets/blue-widgets/blue-widget-content1, so on and so forth).[/li] How affective is it for reducing rejection rate for human visitors? (stickiness) If this is indeed so affective, why is it that lots of sites, even ones that are apparently well designed for seo visibility, do not have such site wide navigation Anyone tested the different approaches and found any difference?
It works, that much is known. How much so depends on the site. If you're going to use this as an internal linking tactic, make sure you put your users' needs and expectations first (in other words, make sure the keywords identify what's on the page) and forget about SEO. Before you know it, your menus will be optimized without you even realizing it or trying.
