Hi One of my site have sitemap links, which is reflacted in Google Webmaster tool, but its not showing in Google SERP. Can anyone tell me when can I expect to see sitemap links in Google SERP results.
I have a site that's been showing sitelinks in webmaster tools for 18 months, they are still not in the SERP's. Webmaster tools is buggy, i wouldn't worry about them.
As google itself stated in webmaster tools, if google "sees" the sitelinks and reports them in webmaster tools, this doesn't guarantee that the links would be shown up in google under your website. In fact it's the the search engine itself that chooses to display those links if they are very well related to the keyword the user searched. Also, I've never seen sitelinks in google other than for number 1 site, so unless your website is there, there's no chance for them to be displayed (based on my observations only). Hope this helps.
I agree that the sitelinks are only showing up for the #1 ranked website. You will likely only see your own sitelinks if you show up first for your website/company name.
Sitelinks have nothing to do with the SERPs because they show the relative quality and reliability of a certain site when a special term is being searched for and usually the informative sites are like this.
