Till last month Google cache my articles2u.com blog home page within a minute....(after blog post) But now my blog home page cache not updating very fast. I change settings in feedburner, i active noindex options on feedburner publicize tab. Please help me to solve this problem...I need to deactivate noindex options?
You mean you use the noindex option for de-indexing your RSS feed, right? This should not affect the indexing of your home page. Have you tried adjusting your crawl rate manually in Google's Webmasters Tools? Also, tweeting each new post (or posting on other social networks) helps faster indexing.
