To help Google index your blog, use one of several sitemap plugins and point your Google Webmaster service to the sitemap xml.
Add configuration to _config.yml
Add a robots.txt file to the root folder.
Submit your sitemap url to Google for verification, log into Google Webmaster Central using your Google account.
I’m using CloudFlare to front the website.
Have Google crawl your website by registering your sitemap.xml to the Crawler
You may not see the data immediately, but after Google finish indexing your website (about half a day), you can see your website status (like Crawl errors, Search Analytics etc.).
