Mambo

Just curious. I've built couples of website for my clients and myself. I notice that those nuke and mambo/Joomla platform come with very strong SEO capability compared to the one I wrote from scratch.

What do you guys think?

I've tried everything in the one I wrote from scratch:

title
h1
meta keyword
meta description
alt image.

do I need anything else?

In addition to h1

h2 - h6 may also be consider
bold text
italic text
Actual anchor link text
depth of link
internal linking
Keywords in content
Description in content
Title = contain keyword
(all onpage factors)
