Hi friends, 
sitemap added .. all pages are indexed. no duplicate content. no notification on webmaster tool. any suggestion what do i do ?
 

Maybe not all of them are indexed yet, the landing page usually show up first. Did you put proper meta-tags inside of product pages? You could check Google Search Console if it detects any problem, or existing issue. If not, guess you will just have to wait.

Did you recently create the page or request indexing? It can take time for Google to index your page; allow at least a week after submitting a sitemap or a submit to index request before assuming a problem. If your page or site change is recent, check back in a week to see if it is still missing.

 

submit you sitemap competently maybe this issue.
