hei i just bought new domain pr2,but why google didnt update my cached? how to make update cached more fast? and how many times per month or week or day?
Use Google Webmaster Tools. It will take you much more deeper. It will show when was your Home page accessed and many other interesting facts!
1-Lets Google to remove all existing URLs, which you may not want to use from the old website. I mean if you are starting a new website with your new domain, then you should remove all existing links from Google, because you may get 404 errors, if someone finds your older pages in search engines. If I am right, then you can do that in Google Webmaster. Just create an account and use all useful tools. 2-If you want to get indexed faster, then you should use the social networking. Submit your articles to the social networking websites such as LotText - Propeller - Digg. If you do that, then Google´s Crawlers will be there on your site after few hours.
@ameran i have been alrady indexed by google but,my problem is cached..last update cached was 31 july
31 July , i think thats fine. Google caches those site fast which changes very fast like news site. In your case if its 31 July, then not at all worry. even bigger sites also has 1-2 days past date. Not at all any problem
