I don't know why my site listing in Yahoo search engine decreased so rapidly these three days for about 6000 to only 3000.Is that because of my sitemap.xml or sitemap.txt?
It is probably because of decrease in number of backlinks to your site OR due to some indexing problem of your site. ---------------------------------------------------------------- Funny Phrases | Valentines Day | Funny Commercials | Funny Riddles
dont forget search engines such as yahoo and google are constantly tweaking their algo's so one minute you could have a great ranking, the next you might have a crap ranking. its all part of seo my friend. during the last week my ranks has dropped slightly in google and increased in yahoo. im sure soon that will change again.
