A SEO Speedwagon member reported about how to get more index count at Yahoo!. Now submitting sitemap feeds to Yahoo in default Google feed file format sitemap.xml can increase the index count by triple. Exporting sitemap.xml file directly to urllist.txt. which is recommended file format by Yahoo! can create a bloat. Google sitemap.xml file have many URLs which you won't like to get crawled. Using urllist.txt format led to listing of incidental graphics files in crawling list and increasing the file size. It is better to submit feed in sitemap.xml.
