I have a doubt in robots.txt - need help

I have uploaded robot.txt, which conatained

User-agent: *
Disallow: /


so after i did , for the past 2 days , i have a problem in my website adsense ads are not displaying properly.

sometimes it shows sometimes not.

when i checked in google webmaster tools.
it says that my robot blocked robot visit on my page.

Now i removed my robots.txt

Now i want to know
will the site show adsense ads normally.
will the google index my web pages.

Thanks

 

Since you have removed the robots.txt code, now your webpage would be indexed and your adsense ads will also be visible. The reason your ads were not visible was the fact that you had blocked the all crawlers to access the website and it also disabled the ad sense crawlers to vist your webiste, hence your ads were stopped being visible there. In case you want not to index your website and wants that ad sense ads continue to be visible then use following code:

User-agent: *
Disallow: /

User-agent: Mediapartners-Google*
Disallow:

 

User-agent: *
Disallow: /

User-agent: Mediapartners-Google
Disallow:

(no star after google)

 

* in the code has been added because there are several media bots that Google uses to crawl the webpages and put ads on the web pages. So * will cover all those bots and enable them to access the webpages. However, I believe that without using * would do the same job. But if you use the *, it will give you clear picture of the process.

 

Thank you very much.

What you said is 100% correct.

Now adsense ads starts appears on my web pages. Google crawls my site now. Now i am waiting for the google index.
