update of cache pages

[adi123]

How do i "force" the search engine to go to a web site and update pages. For exmaple if there's an existing search "cached" in yahoo and the info has changed. I want future searches for the same search criteria to go to the web site itself and update the pages that were cashed. Could someone "shed" some light on this issue ??

thanks

There are 2 options to do it,

1. Pay Yahoo for Sitematch PFI and get your site crawled every 48 hours, This way everytime your site is updated yahoo will have the latest cache of the page,

2. You dont have any control over this option but it works, Get a lot of links to the page which you want updated often, Yahoo slurp likes lot of links to a page and it will crawl that page regularly if it finds many links pointing to that page,

Remember crawling frequency also depends on the updation of your pages, if you dont update your pages often then there is no need for the Bots to visit it regularly.

I would like to refrase the question differently. Let's assume that Yahoo Search cached a document from a web site for a specific search criteria. Let's assume that this doument or web page no longer exist on that web site. When i perform another search for the same criteria yahoo brings the cached pages. I want to "force" the search engine to go back to the web site and update the cached pages and making sure that the previous pages that no longer exist on the web site will be removed from the cached pages. Any suggestions ????

It is almost impossible to do that unless you pay the search engines for regular crawling, Regular crawling ensures updated cache of the page,

You dont have any control over the free crawling of a search engine and there is nothing you can do to change the update pages in search results,

adi123, are you talking about having the cache of a page that's no longer on line removed from the cache, like you can do at Google?

Yahoo isn't quick with removing 404 pages, which is a good thing when a site has unintentional downtime but not as good for when a page is meant to be gone.
