Text sitemaps contain one website url per line. Many search engines including Google and Yahoo can scan text sitemaps.
Improve compability between text sitemaps and search engines:
For Yahoo, name the primary text sitemap file urllist.txt.
Save text file sitemaps as UTF-8 documents. Especially if you have website urls with non-English characters.
Each text sitemap file should contain no more than 50.000 urls.
The example of text sitemap is; http://www.bimadeals.com/urllist.txt
