The AllWebMenus SEO CSS Menu Addin adds the following functionality to AllWebMenus for creating SEO-friendly menus, through either the "sitemap-based SEO" or the "on-page SEO" method:

Sitemap-based SEO:
Search engines will crawl your menu links through a single sitemap file that they find on your website.
Use the "Generic Sitemap" button to create a sitemap based on your menu structure.
A simple .html file will be exported that contains all your menu items along with their links (as <A> tags).
Then, just add a "sitemap" link on your index page (or any other page crawled by search engines) that links to that file and your most important pages of your website (those in your menu) will be indexed by the search engine crawlers, without any hassles!
Additionally, you may also use the "Google Sitemap" or "ROR Sitemap" to provide more info for certain search engines.
With this method (compared to the "on-page SEO" method below) you do not need to add a lot of HTML code to your page (other than just adding a simple link to the sitemap file).
On-page SEO:
Search engines will crawl your menu links through <UL><LI> HTML code that you add to your pages.
Use the "View sample <UL><LI> code" button to see how your HTML code should be structured.
As you can see there, your menu links are presented as standard <A> tags.
Therefore, search engines will index them automatically whenever they crawl a page that contains the related <UL><LI> HTML code.
Example:
<ul id="awmULLI-menu" style="display:none;">
<li><a href="index.html">Home</a></li>
<li><a href="item1.html">Item 1</a></li>
<li><a href="item2.html">Item 2</a>
<ul>
<li>Item 2.1
<ul>
<li><a href="item_211.html">Item 2.1.1</a></li>
<li><a href="item_212.html">Item 2.1.2</a></li>
<li><a href="item_213.html">Item 2.1.3</a></li>
<li><a href="item_214.html">Item 2.1.4</a></li>
</ul>
</li>
<li><a href="item_22.html">Item 2.2</a>
</li>
</ul>
</li>
<li><a href="item3.html">Item 3</a>
</li>
</ul>
Through the above <UL><LI> HTML, search engines will index all pages referenced by the <a> tags.
