I don't know of any way to directly influence the speed with which Google will crawl and index sites, or update the cache. Setting update frequency in your sitemap or meta tags will have no effect -- Google crawls and indexes your site based on other factors, such as site authority and history. A sitemap just helps Google find all your pages eventually (on its own schedule).

Updates to the Google cache typically trail updates to the actual search index by quite a bit -- days or weeks. You cannot use the cache as an indication of what is in the index. A better way to check is to search on exact strings in your new pages -- you may find them indexed but not yet in the cache.

As to how to speed up crawling and indexing, the best way to do this is to build the authority of your site, and that means building inbound links.

Hi, jreseo thanks for your response and suggestion . I have check my site on Google and it not detect the changes on my site. Google just detect my site on 3 weeks ago

Any other ideas?
Thanks

Try to submit your XML sitemap in Google Webmaster tool.

And you can use social bookmarking for fast indexing..websites like digg.com can really help in easy indexing of site as they are fantastic traffic.

Also use Pingoat Service. Send Ping to Google and many other websites, they will release spiders on your blog and they will update their information about your website

We also have pingomatic.com to do so...

Wow , thanks ..........
Thats great idea. About Submit my sitemap site, it was done some weeks ago

But Google stay not detect that. I will try your other suggestions.
Thank you so much

You can't tell to google to update their cache. They are the one who set on when to update. Try to submit your sitemap, I think this can help.

This is good information. I have two websites that are showing old pages that do not exist anymore.
www.tillsvisalaw.com
www.globaldirectsavings.ca

I was waiting for google to update them. about 6 weeks wait time on GDS. I will add the site map and inbound links. I have added the websites to various directories the old pages are still showing up. Is there another way. These pages are gone. Only when I add the URL in the address bar will peopel see teh new site. I will get his old settings from the randon "search". Is there something I can do? Do I need to contact google directly, or what measures must be done?

Use Google webmaster tools ( http://www.google.com/webmasters/ ). In URL removal section there is an option for just clearing the old cashed page. You can update cache from there.
