Wordpress Plug ins for SEO

[humbledmarket]

Hello Warriors,
I know this has been ask many times but I've noticed numerous changes and advancements in Plug ins as well.

I'm looking for some essential plug ins I need for SEO on wordpress and other plug ins for general good use.

I prefer free plug ins however I don't mind paid plug ins if you have a suggestion.

I currently know of these two:
All in One SEO
XML Sitemap Generator

Are there more I can add?

Also how else can I SEO a wordpress blog to target specific keywords? Do tags work and how do I add tags as I see on blogs with a side bar with tons of tags are they simply text widgets?

Thanks

The first set of plugins in the list in this article are SEO related:

Wordpress Plugins: A Recommended List | Create an Awesome Home Business

There's a brief description of each and a link to the plugin.

WRT tags, I use them as an internal filing system, along with categories. Categories are my filing cabinet, tags are folders within the cabinet. For example, articles on WordPress Themes would go into the WordPress category and the wordpress themes tag.

This makes it easy for both people and the search engines to find their way around the site.

Cheers,

Martin.
