I have a search based navigation web-site. Each query has filters as well as sort-by. The search results point to end-pages inside the site. Each of those pages has many outlinks to other end-pages. Currently I have a XML sitemap which directs crawlers to all the end pages. I'm trying to add a silo sitemap directory to improve SEO. Assuming this is the right direction I have a couple of options:
- end pages sorted alphabetically.
- Pages by major search filters, and then divide alphabetically.
- Pages for every filter and cross option between them and the sort-by.
Which would you recommend and why?
NOTE: I'm not referring to a XML sitemap.
