I have more than 400 posts on my blog but in webmaster tool i saw sitemap just 26 urls submitted and 18 urls indexed. that's why?
Most likely your sitemap did not contain all URLs. Contact the developer of the sitemapper tool you use and ask for possible reasons.
May be there is some problem in the hyper link you have created on the site map. Please check the Links Again.
Maybe your sitemap did not contain all URLs. Need to create your sitemap again and upload it again on webmaster.
YAA THERE IS A PROBLEM IN THE WEBMASTER TOOL AT THE BEGNING AT HO TO SUBMIT A SITE MAP The default number of URLs in Blogger XML sitemap is 26, so within Webmasters tools you will see there are 26 total URLs. But if you have more than 26 posts and less than 100 posts then you can add the following sitemap: atom.xml?redirect=false&start-index=1&max-results=100 For more than 100 posts, add a second sitemap:YAA THERE IS A PROBLEM IN THE WEBMASTER TOOL AT THE BEGNING AT HO TO SUBMIT A SITE MAP The default number of URLs in Blogger XML sitemap is 26, so within Webmasters tools you will see there are 26 total URLs.
