DENNY DOUBLEPLUS MARKETING  It's a fact - having a SiteMap on your website increases your position in the organic search engines - sometimes dramatically so. This plugin for Rapidweaver creates a SiteMap for you so you don't have to. The cost of this plugin is completely insignificant considering what it effectively does. I'm still learning some of the ins and outs, but believe this is a must. When you update your website (add or delete pages), this plugin updates your SiteMap automatically! Install, setup, and forget about it! Here is my example of my "effortless" SiteMap: http://doubleplusdeals.com/sitemap/sitemap.html

Special note, if you go to the developer's site (http://www.loghound.com/), they have many more MUST-HAVE plugins and the more you buy the lower the pricing! Just gotta love that!

AMPLIFYFITNESS  I've used this plugin with RapidWeaver for over a year now and I have seen a huge difference in my Google and Yahoo tracking numbers. SiteMap has built a simple, accurate, and compliant map that is frequently used by visitors and especially make finding recent blog entries easy to find.

The plugin is updated often, filled with improvements to match RapidWeaver's advancements. Granted a site map generator isn't the "sexiest" of plugins, but is so worth the validity it brings to a website site.

Highly recommended.
