Why is it when searching my website on google there's no result. Before when searching it, it was on first page and 1st result on google. This happened when i switch scripts from AVS to Smart Tube Pro.
May be you have change the URL of your website pages. or any major changes i.e Title or poor redirection ?
Did you get a notification in Google Webmaster Tools? Do you not even get a result with: info:domain.com site:domain.com (Just type it into Google search.) For further, more specific advice, you're going to need to provide more information.
So did you check Google Webmaster Tools? There will be a notification in there if you have been de-indexed due to a penalty. It will also contain more information about it.
I have this message last July 8, 2012. This is because I moved to other host and changed script from Adult Video Script to Smart Tube Pro
Google has de-indexed your website. There's no use of doing this now. Try and contact Google and see if they can reindex your website. Is your website searchable on bing and yahoo and duckduckgo?
So now we know the exact problem, which is that Google has blocked your site from its search results. Yahoo, Bing, etc., dont follow strict rules, but Google does, thats why your site has been unindexed. My advice would be that you contact Google and ask them for the exact reason, because your site wont come back up automatically
If Google can't access a site, it will temporarily be de-indexed. It's failing altogether to fetch pages from your site, which suggests there is a technical issue. If you had been removed for a violation of guidelines then you would have had a notification. Take a look in the crawl errors. In particular, click on DNS and server connectivity. That will give you a history of any DNS or connectivity issues. Do you have any other websites with the same host? Specifically, on the same server?
your website might be not get indexed in google so its display no result, create xml sitemap and integrate with site and add in google web master tool
I have created a sitemap and submitted it but when I tested have this error "Error occured while testing a sitemap. Reason: Unable to fetch sitemap at this time. Please try again later"
And will continue to fail, until the connectivity problems for GoogleBot are resolved. See my previous post (DNS and server connectivity are checked under crawl errors in Webmaster Tools):
