· Alternate HTML Navigation– Creating an HTML path through the form for the spider works well for sites that don’t have too many pages behind the form. For instance, you could create an alternate navigation in your native sitemap. As long as your sitemap is clearly linked to within the footer of your homepage, the sitemap can lead the spider to different product areas, different versions of the site (such as by country) or different store/campus locations.
· XML Sitemap– For sites that have a lot of pages behind forms, such as a retailer with thousands of locations, creating an external sitemap of all the URLs and submitting it to the engines is the best strategy. In this case, each individual page needs to have a unique URL.
