How to request Google to re-crawl my website? [clo

问题:

Does someone know a way to request Google to re-crawl a website? If possible, this shouldn't last months. My site is showing an old title in Google's search results. How can I show it with the correct title and description?

There are two options. The first (and better) one is using the Fetch as Google option in Webmaster Tools that Mike Flynn commented about. Here are detailed instructions:

1. Go to: https://www.google.com/webmasters/tools/ and log in
2. If you haven't already, add and verify the site with the "Add a Site" button
3. Click on the site name for the one you want to manage
4. Click Crawl -> Fetch as Google
5. Optional: if you want to do a specific page only, type in the URL
6. Click Fetch
7. Click Submit to Index
8. Select either "URL" or "URL and its direct links"
9. Click OK and you're done.

With the option above, as long as every page can be reached from some link on the initial page or a page that it links to, Google should recrawl the whole thing. If you want to explicitly tell it a list of pages to crawl on the domain, you can follow the directions to submit a sitemap.

Your second (and generally slower) option is, as seanbreeden pointed out, submitting here: http://www.google.com/addurl/

The usual way is to either resubmit your site in your Google Webmaster Tools or submit it here: http://www.google.com/addurl/

Google says that it is unable to control when your site is re-crawled. Regardless, you could also check this post on "forcing rewcrawls", I haven't tried it myself but it's worth a shot if you're desperate.

On another note, I might add that you make sure you have a sitemap.xml up as this will also help with SEO.

As far I know, if you resubmit a sitemap it will trigger and crawler of your site.

Nowadays, the revisiting of a website pretty much depends on its popularity, authority and how often its content changes. Having a sitemap.xml containing all URLs is always better. You can also set the lastmod tag of each URL entries. If you don't abuse it, crawlers will take it into account.
