What Makes a Good Navigation Stucture?

What Makes a Good Navigation Stucture on a website?

1. . All links have anchor text appropriate for the target page.
2. The number of links to each page is relative to the importance and ranking difficulty for that page's target keyword(s).
3. Both users and SEs can easily (and intuitively in the case of human users) navigate the entire site.

Thanks for the help. Above do you mean incoming links from external sites?

and make sure that all links are working. =)

Good points outlining the basics; not much to add there.

He means external links and internal.

Some facts that are counter-balanced by different trials.

1. Most eyes find upper left first and most often - so many suggest top nav and left side navs.

2. Alternative - the mouse pointer usually rests to the right side close to the scroll bar making a right nav bar ideal.

3. In SEO nav menus with anchor text the same as the search query can interfer in the snippet (and why many say use meta decription... but that is only true for top & left nav bars in default positioning.

4. AN OPINION - In context with #1 if eyes are upper-left is seems odd to put traditional text or image links links there.... if most eyes go there and most often you want you most important assets there - in a buying domains that IMHO is featured items, sales items, best sellers... anything the time sensitive - not main menus that are like "old salts" telling fish stories... you can easily find these guys anywhere and while the connect you to the general most important pages - enticement is needed "should be upper left".

THus the best over nav menu is right side - leaving top and left of banners and adverts for immediate sales.

each page should link back to home page.
important keywords in anchor text
link related to page including internal as well as external incoming links.
navigation shoud easy to human as well as spider.
your main product pr services pages shoud be proper linked with anchortext form the home page.
